Where the New Climate Law Means More Drilling, Not Less.

HOUMA, La. — Justin Solet planted his foot on the sting of his camouflage inexperienced boat in Bayou Chauvin and pointed to a pure gasoline rig protruding from the waters forward. An internet of pipelines and rusted storage tanks jutted up from the marsh behind him as a shrimp boat floated previous and markers for crab traps bobbed on the water’s floor.

“We’re water folks,” mentioned Mr. Solet, 37, a member of the United Houma Nation, a Native neighborhood with many shrimpers, oyster farmers and crab fishers who depend upon the Gulf of Mexico’s bounty. “That is their livelihood. And it’s proper subsequent to those tanks that I don’t suppose have been mounted or serviced in years.”

Oil and gasoline wells and drilling tools are a persistent risk to the fishing trade within the Gulf. Along with the 2010 Deepwater Horizon catastrophe, there have been dozens of less-noticed oil spills. Final month, on the primary day of Louisiana’s inshore shrimp season, a tank platform collapsed, pouring 14,000 gallons into Terrebonne Bay and ruining the catch.

Now, extra drilling could also be on the best way.

Underneath a brand new local weather and tax regulation, the federal authorities will lease lots of of hundreds of thousands extra acres for offshore drilling within the Gulf within the subsequent decade, even because it invests $370 billion to maneuver the nation away from fossil fuels and develop wind, photo voltaic and different renewable power.

Extra Gulf leasing was among the many concessions that Democrats and President Biden made to Senator Joe Manchin III of West Virginia, a Democrat who champions fossil fuels and whose vote for the laws was essential within the evenly divided Senate.

It got here regardless of Mr. Biden’s promise as a candidate to finish new drilling on public land and in federal waters “interval, interval, interval.” And it got here although Deb Haaland, who will oversee the leasing as the inside secretary, mentioned as a congresswoman in 2020 that “we have to act quick to counteract local weather change and preserve fossil fuels within the floor.”

The leasing additionally follows a warning from the Worldwide Power Company that nations should cease approving new fossil gas initiatives if the world has any hope of maintaining the common world temperature from rising 1.5 levels Celsius above preindustrial ranges. That’s the brink past which scientists say the probability of catastrophic local weather impacts will increase significantly. The planet has already warmed 1.1 levels Celsius.

The brand new regulation condemns communities like Houma, that are already coping with storms made extra intense by local weather change, to continued reliance on oil and gasoline drilling, whilst different elements of america race towards renewable energy, mentioned Cynthia Sarthou, government director of Wholesome Gulf, an environmental group primarily based in New Orleans.

“We have been actually offered down the river and needed to serve the function of bargaining chip with out the enter of oldsters in Louisiana,” mentioned Jack Sweeney, an activist with the Louisiana Bucket Brigade, an environmental nonprofit group. The group’s members traveled to Mr. Biden’s residence state of Delaware final month to level out that, whereas Congress and the administration are enabling extra drilling within the Gulf, they’re defending the Atlantic and Pacific coasts. “The remedy of coastal Louisiana is so completely different,” he mentioned.

Erik Milito, president of the Nationwide Ocean Industries Affiliation, which represents offshore power firms, mentioned the brand new regulation created an “even enjoying discipline” for offshore oil and gasoline alongside wind. His group mentioned oil and gasoline manufacturing within the Gulf was projected to common about 2.6 million barrels of oil equal per day via 2040, and mentioned the trade would assist an estimated 372,000 jobs within the area throughout that point.

As oil drilling know-how improves, the bodily footprint of the trade is shrinking, Mr. Milito mentioned.

Underneath the brand new regulation, the Inside Division should settle for by Sept. 15 the very best bid it had acquired final 12 months to lease 80 million acres within the Gulf of Mexico. (The sale was canceled in January by a federal decide who dominated that the Biden administration had not sufficiently taken local weather change under consideration, but it surely has been revived beneath the brand new local weather regulation.)

Analysts have mentioned the lease sale may produce as much as 1.1 billion barrels of oil and would most certainly emit 723 million metric tons of carbon dioxide into the ambiance over its lifetime.

Ms. Haaland mentioned this week the company was “dedicated to implementing the regulation,” together with the mandate for extra lease gross sales on public lands and in federal waters. Environmental teams have indicated they nonetheless plan to problem the sale.

The brand new regulation additionally requires the Inside Division to lease two million acres in federal lands onshore and 60 million acres offshore annually for oil and gasoline improvement earlier than it may possibly approve federal leasing for wind, photo voltaic and different renewable power initiatives.

Brian Deese, director of Mr. Biden’s Nationwide Financial Council, mentioned no communities have been sacrificed throughout negotiations over the laws. He known as the brand new regulation “essentially the most vital laws in American historical past to not solely meet the second of the local weather disaster however construct a clear power manufacturing base in america that can energy renewable power and jobs for years.”

Mr. Deese famous that the regulation contains $60 billion to assist low-income communities tackle what he known as “the legacy of environmental air pollution and environmental justice.”

So whereas Occasions employees members could vote, they aren’t allowed to endorse or marketing campaign for candidates or political causes. This contains collaborating in marches or rallies in assist of a motion or giving cash to, or elevating cash for, any political candidate or election trigger.

The Inside Division this week proposed to strengthen security laws for offshore oil and gasoline drilling that have been loosened beneath the Trump administration. But there is no such thing as a cash the in new local weather regulation or federal plans to restore the greater than 8,600 miles of lively offshore pipelines that lack enough oversight, in accordance with authorities estimates.

Activists mentioned that placing much more drilling rigs within the Gulf, the place they’re susceptible to bigger and extra frequent hurricanes due to local weather change, would result in catastrophe.

The area is already residence to the nation’s longest-running oil spill. Undersea wells owned by Taylor Power have been seeping into the Gulf of Mexico since 2004, when a manufacturing platform about 10 miles off the Louisiana coast was broken by Hurricane Ivan. Multiple million gallons of crude have been collected and eliminated up to now, and the spill continues to be lively. When Hurricane Ida slammed into southeast Louisiana final 12 months, it triggered 55 oil spills, together with a spill close to a fragile nature reserve.

Comparatively small spills, just like the current one in Terrebonne Bay on the opening day of shrimp season, not often make nationwide information.

Mr. Milito, the spokesman for the trade group, mentioned that ageing tools remained an issue. “It is among the dangers associated to grease and gasoline improvement, but it surely’s a danger the trade takes severely,” he mentioned. Requested if the Gulf was a “sacrifice zone,” he mentioned. “If we weren’t to proceed leasing within the Gulf of Mexico we might be making a far better sacrifice for Individuals.”

In a area tied to each fishing and oil drilling, it’s maybe unsurprising to search out the annual Louisiana Shrimp and Petroleum Competition, hosted over the Labor Day weekend in Morgan Metropolis, a city about 70 miles west of New Orleans. Lots of of individuals streamed beneath an overpass two weeks in the past to pattern fried alligator and jambalaya, tour a decommissioned oil rig nicknamed Mr. Charlie, and think about the blessing of the shrimping fleet alongside the Berwick Docks.

Skipper Williams, 71, who mentioned he got here from a household of boat captains, mentioned the area prided itself on each gas and meals.

“It goes hand in hand,” mentioned Mr. Williams, who runs a sporting items retailer that sells T-shirts on the pageant. As for oil spills, he mentioned, “Does it harm? Yeah. however does it harm endlessly? No.”

Advised that the brand new local weather and tax regulation ensured extra offshore oil and gasoline leasing within the Gulf, Mr. Williams mentioned: “I believe that’s the proper factor to do. I imply, what do you suppose, we simply convert all automobile to electrical energy proper now? You might have a hurricane down right here which we now have yearly virtually. Nicely, you’re not going to get very far with an electrical automobile.”

A.J. Richard, 68, labored as a pipe fitter for oil firms all through the Gulf Coast and abroad for 36 years. He mentioned Mr. Biden had “shut all the things down” within the oil trade and blamed the president for inflation, together with the $18 he and his spouse Cathy, 66, paid on the pageant for 2 hamburgers and two orders of fries.

The couple mentioned they weren’t conscious that Mr. Biden had signed a regulation guaranteeing extra drilling leases within the Gulf however didn’t imagine the president deserved credit score for serving to the area. Mr. Richard mentioned he believed the world’s solely hope was the 2024 presidential election.

“So long as it’s a Republican — it doesn’t must be Trump — a Republican can straighten all of it again up and folks can begin going again to work,” mentioned Mr. Richard, who’s retired.

Wanda Presa, 46, moved to Amelia, La., from New Jersey 14 years in the past and now works as captain on a riverboat on line casino. She mentioned she frightened about local weather change however was heartened to listen to that oil and gasoline leasing would proceed within the Gulf. It means extra residents could have disposable revenue to spend.

“If there’s extra leasing within the Gulf, which means I really feel somewhat safer in my job,” she mentioned.

Even some whose livelihoods have been harm by current spills mentioned they need the oil trade to thrive.

At a shrimp dock within the close by city of Dulac, Kimberly Chauvin, co-owner of the David Chauvin Shrimp Firm, mentioned she was livid concerning the spill on the primary day of shrimp season. Fishermen she works with “wakened within the oil” that day to search out the slicks had fouled their catches, and the extent of the monetary harm received’t be clear till the top of the season.

“We do have a double-edged sword,” she mentioned of the Gulf’s reliance on oil and gasoline as she lifted recent shrimp from blue plastic buckets into plastic luggage for purchasers.

However Ms. Chauvin mentioned she was skeptical about local weather change and added that oil and gasoline are very important to the Gulf.

“We do want extra leases,” Ms. Chauvin mentioned. “We simply additionally want extra oversight.”

Mr. Solet nodded silently as Ms. Chauvin spoke. Afterward, he acknowledged that he treads rigorously with buddies and neighbors. His opposition to grease and gasoline enlargement within the Gulf already has triggered friction with relations who work within the trade, he mentioned.

“Folks down right here don’t prefer to be labeled as ‘you reside in a sacrifice zone,’ as a result of what they hear is, ‘You’re coming for our jobs. You’re coming for the meals on my desk, the garments on my little one’s again, a lifestyle I really like,’” he mentioned.

Mr. Solet himself labored for 9 years on oil rigs till the Deepwater Horizon spill turned him to activism. He additionally comes from an extended line of economic fishermen whose livelihoods he has seen altered by coastal erosion, waters which have been battered by more and more devastating hurricanes or threatened by ageing infrastructure.

“I’m afraid by the point my youngest one is 16 years previous, I received’t be capable of carry him right here,” Mr. Solet mentioned. “It’s going to be gone.”

Are 'deaths of despair' really more common for white Americans? A UCLA report says no

Are 'deaths of despair' really more common for white Americans? A UCLA report says no

Nakeya Fields has seen how the stresses that come with being Black — racial injustice, financial strain, social isolation — can leave people feeling hopeless and push some into substance abuse.

It’s one of the reasons the Pasadena social worker started offering “therapeutic play” gatherings for Black mothers like herself and children.

“I’m trying to host more safe spaces for us to come and share that we’re suffering,” the 32-year-old said. “And honestly, the adults need play more than kids.”

Yet while Black and brown mental health practitioners such as Fields have labored to address these issues within their communities, a very different conversation has been occurring in the nation at large.

For years, discussions about America’s substance-abuse crisis have focused almost exclusively on the narrative that it is white, middle-age adults who face the greatest risk of dying from drug overdoses, alcoholic liver disease and suicide.

The theory, which was presented by two Princeton economists in 2015 and based on data from 1999 to 2013, argued that despair was behind rising premature mortality rates among white Americans, especially those who were less educated.

Virtually overnight, the “deaths of despair” concept began to drive the national discourse over populist far-right politics; the rise of Donald Trump; and deepening political polarization over such topics as addiction treatment, law enforcement and immigration.

But after roughly a decade, researchers at UCLA and elsewhere have begun to dismantle this idea.

In a study published recently in the journal JAMA Psychiatry, authors found that deaths of despair rates for middle-age Black and Native Americans have surged past those of white Americans as the overdose crisis moves from being driven by prescription opioids to illegal drugs such as fentanyl and heroin.

While the opioid crisis did raise drug overdose deaths among white Americans for a time, it was an anomaly, said Joseph Friedman, a social medicine expert at UCLA’s David Geffen School of Medicine who was the lead author of the journal analysis. In fact, by 2022 the rate for white Americans had started to dip.

“What’s really important is that now, with these three causes of death, the gap has closed, and it’s moving in the other direction,” Friedman said.

The analysis found that deaths of despair for Black Americans hit a rate of 103.81 per 100,000 people in 2022, compared with 102.63 for white Americans. The rate for Native American and Alaska Native populations was even higher at 241.7 per 100,000 people in 2022.

The UCLA analysis doesn’t specify the midlife personal issues that might have led to addiction or suicide.

But the authors say that flaws in the methodology of the 2015 deaths of despair report skewed its conclusions about who was most at risk. Specifically, Friedman said that it failed to give enough consideration to long-standing racial inequities that Black Americans experience in income, educational attainment, incarceration and access to quality medical care, all of which can contribute to drug use and poor mental health outcomes. And statistics for Native Americans weren’t factored in at all.

“It was burned into the American psyche that it was white people in the rural U.S.,” Friedman said. “It was just a very small piece of the truth that was very interesting but was widely sold as something it wasn’t.”

Another recent worrying sign, Friedman says: Deaths of despair among Latinos are starting to catch up to those among Black and Native Americans.

Princeton professors Anne Case and her husband Angus Deaton, winner of the 2015 Nobel Prize in economic sciences, were thrust into the media spotlight when their deaths of despair findings were first published. Deaton told NPR that during a visit to the White House, even President Obama asked him about the phenomenon.

Their 2020 book, “Deaths of Despair and the Future of Capitalism,” was described by publisher Princeton University Press as “a troubling portrait of the American dream in decline.”

“For the white working class, today’s America has become a land of broken families and few prospects. As the college educated become healthier and wealthier, adults without a degree are literally dying from pain and despair,” the publisher said.

Fields, who employs yoga and pottery in her therapy, said this framing was misleading and racially biased.

“I’m actually flabbergasted that somebody has a term called ‘deaths of despair,’” Fields said. “It’s ‘despair’ when white people experience this suffering. But when we experience it, it’s just what we have to deal with.”

Both Friedman and Fields say their critiques are not intended to minimize deaths among white Americans.

Still, Friedman wonders: “How do we empower Black and Native American communities in a way that enables them to treat these problems?”

Racism must be considered when trying to make sense of the crisis in premature deaths, says Dr. Helena Hansen, head of UCLA’s Department of Psychiatry and a senior author on Friedman’s analysis. Hansen, who is Black and specializes in addiction psychiatry, also co-authored the book “Whiteout: How Racial Capitalism Changed the Color of Opioids in America.”

For years, pharmaceutical companies steered expensive prescription pain medications, such as the opioid Oxycontin, as well as the most effective medications for opioid-use disorder, to white Americans with good access to healthcare, she said.

But at the same time, Black and brown Americans were unfairly subjected to law enforcement policies that prioritized incarceration for illegal drug use over increasing access to more humane medical strategies to help them, further harming already vulnerable communities, Hansen said.

“In our society, people with access to the new technologies and pharmaceuticals are more likely to be white,” Hansen says. “None of this is by accident. All of this is the direct result of careful racially and class-segmented marketing strategies by pharmaceutical companies.”

This two-tiered system arose because drug manufacturers, doctors and policymakers have for too long failed to see people from historically marginalized communities who live with addiction and mental health crises as worthy of the same sympathy and treatments that many white Americans receive, Hansen says.

Joseph Gone, a professor of anthropology at Harvard who has spent 25 years studying the intersection of colonialism, culture and mental health in Indigenous communities, agreed.

“Deaths of despair have been a reality for Indigenous communities since conquest and dispossession,” he said.

“It’s amazing how much grief our people contend with from early deaths — there are not that many communities in America that bear it quite the way we do,” said Gone, who is a member of the Aaniiih-Gros Ventre tribal nation of north-central Montana. “Until we acknowledge and take responsibility for the casualties of colonization, which endure to this day through deaths of despair, it’s going to be very hard to turn this around.”

Gone, who has collaborated with Friedman on previous research, says the mental health crisis in tribal nations is aggravated by widespread joblessness and generational poverty, and a lack of healthcare resources to treat people in need of immediate or long-term treatment.

Just one traveling psychiatrist serves reservations spread across both Montana and Wyoming — a region covering more than 243,300 square miles — mostly to manage patients’ prescriptions, he says.

And “for all of Indian country, we’re talking about a very small number of in-patient psychiatric facilities,” Gone says.

General practitioners can serve as a first line of defense, but they are not necessarily equipped to address the ongoing life crises that can lead to excessive drug and alcohol use, Gone says.

Fields says it’s important to address mental wellness issues early, before people reach a crisis point and become another statistic.

While her focus remains on Black women, she’s developed additional programming for adults, families and children, such as developmental screenings that measure for high stress levels. In June, Fields will co-present “Rap 4 Peace,” a conference and gala featuring hip-hop artists talking about mental health and reducing gun violence.

“This ‘tragedy of despair’ lives in us,” Fields says. “We breathe it. We go outside hoping that nobody will harm us or our children because they feel threatened by us. This is truly harmful to our bodies.”

SpaceX plans to launch 90 rockets from Vandenberg Space Force Base by 2026. Could that harm the coast?

SpaceX plans to launch 90 rockets from Vandenberg Space Force Base by 2026. Could that harm the coast?

SpaceX plans to launch 90 rockets into space from a Santa Barbara County military base by 2026, tripling the number of blasts rocking the coastal community — and raising concerns from neighbors and environmental groups about the effects on marine life.

Founded by billionaire Elon Musk, SpaceX has ramped up the number of rocket launches from Vandenberg Space Force Base in recent years, and it has made clear its desire to increase the frequency of blastoffs. But during a California Coastal Commission hearing Friday, U.S. Space Force officials outlined for the first time its own plans to multiply the number of launches from the base, from 37 in 2023 to more than 120 a year by 2026.

The overwhelming majority of those rocket liftoffs would be conducted by SpaceX, which has already done more launches from the base than the commission has approved.

Last year SpaceX breached an agreement with the commission that limited the number of launches to six, sending 28 rockets into space.

It is seeking an agreement with the commission to do 36 launches a year, increasing to 90 in 2026.

The decision by the commission, which was created to protect the state’s coastal resources, will directly affect residents and marine life near the military base that hear and feel the rockets’ sonic booms.

It could also redirect the future of SpaceX, whose pursuit to redefine space exploration is already closely tied with U.S. military interests, given its work as a military contractor.

“The ultimate goal is for this to be more routine and not a huge deal,” said Space Force Col. Bryan Titus, operations vice commander at the base.

Formed in 2019, the U.S. Space Force has been looking to improve its ability to send rockets into space, Titus said, so SpaceX’s ability to launch with more frequency is a benefit to the U.S. military.

SpaceX launched 96 rockets in 2023 from Vandenberg and three other facilities: Cape Canaveral Space Force Station in Florida, NASA’s Kennedy Space Center in Merritt Island, Fla., and SpaceX Starbase in Boca Chica, Texas.

Environmental groups argue that turning launches into a routine event could affect marine life.

“We’re concerned that more frequent launches will result in permanent changes,” said Ana Citrin, legal and policy director for the Gaviota Coast Conservancy.

Federal agencies, including the U.S. Fish and Wildlife Service and National Marine Fisheries Service, monitor the effects of the liftoffs on such animals as sea otters, bats, western snowy plovers, California least terns and California red-legged frogs.

Thus far, the monitoring has shown that some of the animals might react to the blastoff by flushing, or fleeing from their nests and homes, but they return soon after, according to U.S. Space Force officials. No long-term effects have been seen, they said.

SpaceX did not respond to a request for comment.

Flushing or hunkering down after a blast are already signs of wildlife exhibiting signs of stress, said Duncan Leitch, a professor of integrative biology at UCLA.

Most animals can adapt to infrequent incidents, but exposure to more frequent stressful incidents can change their biology as well as their behavior, he said.

In the worst-case scenarios, he said, the ability of birds to communicate could be impeded, and migratory birds could avoid the area. Fish and other animals that use sound to communicate and navigate underwater — including whales — could be affected too.

“Over a longer period of time, there may be reductions in the population of fish as they move away from the sound, or they may be affected to the point that it affects their health,” Leitch said. “It would change the ecosystem as far as other animals that rely on the fish.

“Having sounds that are well into the damaging, or painful, range of decibels now occurring [100] times a year, the animals might not have the ability to change their behavior or accommodate these types of sounds.”

Some environmental groups, including the Surfrider Foundation, are asking the commission to reject the increase.

SpaceX “intends to begin increasing very rapidly, so we’re very concerned about this,” said Mandy Sackett, senior California policy coordinator for the Surfrider Foundation.

More frequent launches could change the way wildlife in the area responds in the long term, environmental groups said.

Members of the California Coastal Commission are also asking whether SpaceX should be entitled to circumvent the permit process, as federal agencies are.

Federal entities negotiate agreements with the commission but ultimately can move ahead even without commission approval. In such cases, the commission’s recourse would be through mediation or the courts.

Because SpaceX is a U.S. Space Force contractor, military officials argue that all launch operations at the base by the company are “federal activities.”

But U.S. Space Force officials said only 25% of the rockets launched into space by SpaceX are carrying payloads for the Department of the Defense.

The vast majority of the liftoffs are for the company’s private benefit, raising questions about why SpaceX can dispense with permits when 75% of its blasts from the base don’t involve the U.S. government.

“That is still pretty skewed for me,” Commissioner Mike Wilson said during a meeting Friday.

Some commissioners — whose focus is usually on environmental protection, development and water issues during their monthly meetings — also brought up the war in Ukraine during Friday’s discussion.

“I question the national security public benefit of concentrating that much power, literally communication power, in one company that we’re enabling in this case,” Wilson said. “[SpaceX] has already showed that it will play in international conflicts at the will of one human being.”

Wilson was referring to reports that Musk’s company refused to allow Ukraine to use satellite internet service from Starlink, a subsidiary of SpaceX, to help it carry out an attack against Russia in September 2022.

“If the idea is that we’re supporting these permits on the side that we’re promoting national defense, and then a single company is able to dismantle our allies during armed conflict — that really doesn’t align,” Commissioner Justin Cummings said.

“I suspect that would violate our strategies around national defense.”

Titus declined to address the question, saying it was “out of my lane,” but he said he would try to get answers to address the commissioners’ concerns.

Some commissioners on Friday also argued that SpaceX, not U.S. military officials, should be making the company’s case in front of the agency.

“When this comes back, I think it would be really important that a representative from SpaceX comes to the meeting,” Cummings said.

Cummings said it was “ridiculous” for SpaceX not to appear at the meeting, despite multiple efforts from the agency to have SpaceX officials speak.

“They obviously refuse to because they’ve never shown up,” he said.

On Friday, Commission Chair Caryl Hart suggested an agreement might not be possible unless SpaceX changes its stance.

“From my perspective,” Hart said, “I think we’re going to continue to hit significant obstacles in achieving a federal consistency ruling without having SpaceX.”

Pregnant? Researchers want you to know something about fluoride

Pregnant? Researchers want you to know something about fluoride

Adding fluoride to drinking water is widely considered a triumph of public health. The Centers for Disease Control and Prevention says the cavity-prevention strategy ranks alongside the development of vaccines and the recognition of tobacco’s dangers as signal achievements of the 20th century.

But new evidence from Los Angeles mothers and their preschool-age children suggests community water fluoridation may have a downside.

A study published Monday in JAMA Network Open links prenatal exposure to the mineral with an increased risk of neurobehavioral problems at age 3, including symptoms that characterize autism spectrum disorder. The association was seen among women who consumed fluoride in amounts that are considered typical in Los Angeles and across the country.

The findings do not show that drinking fluoridated water causes autism or any other behavioral conditions. Nor is it clear whether the relationship between fluoride exposure and the problems seen in the L.A.-area children — a cohort that is predominantly low-income and 80% Latino — would extend to other demographic groups.

However, the results are concerning enough that USC epidemiologist Tracy Bastain said she would advise pregnant people to avoid fluoridated water straight from the tap and drink filtered water instead.

“This exposure can impact the developing fetus,” said Bastain, the study’s senior author. “Eliminating that from drinking water is probably a good practice.”

About 63% of Americans receive fluoridated water through their taps, including 73% of those served by community water systems, according to the CDC. In Los Angeles County, 62% of residents get fluoridated water, the Department of Public Health says.

The data analyzed by Bastain and her colleagues came from participants in an ongoing USC research project called Maternal and Developmental Risks from Environmental and Social Stressors, or MADRES. Women receiving prenatal care from clinics in Central and South Los Angeles that cater to low-income patients with Medi-Cal insurance were invited to join.

Between 2017 and 2020, 229 mothers took a test to measure the concentration of fluoride in their urine during their third trimester of pregnancy. Then, between 2020 and 2023, they completed a 99-question survey to assess their child’s behavior when their sons and daughters were 3 years old.

Among other things, the survey asked mothers whether their children were restless, hyperactive, impatient, clingy or accident-prone. It also asked about specific behaviors, such as resisting bedtime or sleeping alone, chewing on things that aren’t edible, holding their breath, and being overly concerned with neatness or cleanliness.

Some of the questions the mothers answered addressed health problems with no obvious medical cause, including headaches, cramps, nausea and skin rashes.

Among the 229 children — 116 girls and 113 boys — 35 were found to have a collection of symptoms that put them in the clinical or borderline clinical range for inward-focused problems such as sadness, depression and anxiety. In addition, 23 were in the clinical or borderline clinical range for behaviors directed at others, such as shouting in a classroom or attacking other kids, and 32 were deemed at least borderline clinical for a combination of inward and outward problems.

What interested the researchers was whether there was any correlation between a child’s risk of having clinical or borderline clinical behavioral problems and the amount of fluoride in his or her mother’s urine during pregnancy.

They found that compared to women whose fluoride levels placed them at the 25th percentile — meaning 24% of women in the study had levels lower than theirs — women at the 75th percentile were 83% more likely to have their child score in the “clinical” or “borderline clinical” range for inward and outward problems combined. When the researchers narrowed their focus to children in the clinical range only, that risk increased to 84%, according to the study.

The researchers also found that the same increase in fluoride levels was associated with an 18.5% increase in a child’s symptoms related to autism spectrum disorder, as well as an 11.3% increase in symptoms of anxiety.

The amount of fluoride needed for mothers to go from the 25th to the 75th percentile was 0.68 milligrams per liter. As it happens, that’s nearly identical to the 0.7 mg per liter standard that federal regulators say is optimal for preventing tooth decay.

Bastain said that allowed the researchers to compare what might happen to children in two parallel universes: a typical one where their mothers consumed fluoridated water during pregnancy, and an alternate one where they didn’t.

“You can use it as a proxy for if they lived in a fluoridated community or not,” she said.

What that thought experiment shows is that children in the fluoridated community face a higher level of risk. That said, it’s not clear when that risk becomes high enough to be worrisome.

“We don’t know what the safe threshold is,” Bastain said. “It’s not like you can say that as long as you’re under the 75th percentile, there are no effects.”

The study authors’ concerns about the effects of fluoride on developing brains didn’t come out of nowhere.

The National Toxicology Program — a joint effort of the CDC, the National Institutes of Health, and the Food and Drug Administration — has been investigating the issue since 2016. In a report last year that reviewed an array of evidence from humans and laboratory animals, a working group concluded “with moderate confidence” that overall fluoride exposure at levels at or above 1.5 mg per liter “is consistently associated with lower IQ in children.”

The working group added that “more studies are needed to fully understand the potential for lower fluoride exposure to affect children’s IQ.”

A 2019 study of hundreds of mothers in Canada — where 39% of residents have fluoridated water — found that a 1-mg increase in daily fluoride intake during pregnancy was associated with a 3.7-point reduction in IQ scores in their 3- and 4-year-old children.

And among hundreds of pregnant women in Mexico, a 0.5-mg-per-liter increase in urinary fluoride went along with a 2.5-point drop in IQ scores for their 6- to 12-year-old children, researchers reported in 2017.

Bastain and her colleagues write their study is the first they are aware of that examines the link between prenatal fluoride exposure and neurobehavioral outcomes in children in the United States. The results are sure to be controversial, Bastain said, but there’s a straightforward way for pregnant people to reduce the possible risk.

“It’s a pretty easy intervention to get one of those tabletop plastic pitchers” that filter out metals, she said. “Most of them do a pretty good job of filtering out fluoride.”
