Palisades and Eaton firefighters had elevated blood levels of mercury and lead, according to an early study

The immediate risks faced by the firefighters who were on the front lines battling the Palisades and Eaton fires that tore through Los Angeles County may have abated, but long-term health concerns remain.

A team of researchers tested the blood of a group of 20 firefighters who were called to duty when the wildfires hit Los Angeles County communities, and found that they had levels of lead and mercury in their blood that was significantly higher than what health experts consider to be safe — and also higher than firefighters exposed to a forest fire.

The results are part of the longer-term LA Fire Health Study, which is investigating the health impacts of the January fires on those exposed to the toxins it released into the the environment. The team includes researchers from the Harvard T.H. Chan School of Public Health, the UCLA Fielding School of Public Health, UC Davis, the University of Texas at Austin, and the USC Keck School of Medicine.

“What you need to worry about is some of these metals that, when they get burned, they get up in the air,” said Dr. Kari Nadeau, chair of the Department of Environmental Health at Harvard T.H. Chan School of Public Health and one of the researchers working on the project. “They can get into your lungs, and they can get into your skin, and they get can absorbed and get into your blood.”

The group of 20 firefighters — who had come from Northern California to assist in the efforts — were tested just days after the fires were contained. They had toiled for long hours as the two fires razed entire communities, burning homes, cars, businesses, and a still unknown list of chemicals and metals. Combined, the fires killed 29 people and destroyed more than 16,000 structures.

On average, said Nadeau, the firefighters had lead and mercury levels three and five times higher, respectively, than a control group of firefighters who fought a forest fire alone. According to the California Department of Public Health, the average blood lead level for adults in the United States is less than 1 microgram per deciliter.

Researchers are still looking to expand the number of firefighters in the study, as well as the range of toxins they may have been exposed to. Nevertheless, even these limited and preliminary findings bolster a growing worry among firefighters that the L.A. fires may have exposed them to metals and chemicals with long-term health effects.

“The results are pretty alarming,” said Dave Gillotte, a captain with the Los Angeles County Fire Department and president of the Los Angeles County Firefighters Local 1014. “We don’t just fear, but we’re quite confident that we’re going to see health impacts with our firefighters who fought these fires on the front lines.”

Firefighters regularly risk exposure to chemicals and metals — including lead and mercury — when responding to house and commercial fires in an urban setting, Gillotte said. But response to a single house fire, for example, would likely last a few hours, not the days on end of the Palisades and Eaton fires. Firefighters also typically face prolonged exposure to the particulate matter in smoke when fighting wildfires in rural areas — but not the chemicals of an urban setting. The Eaton and Palisades fires presented a combined risk: a wildfire-like blaze with firefighters on the ground for extended periods in an urban setting, with electric vehicles, batteries, chemicals and metals burning in high heat, mixing and spreading with the same wind that was spreading the flames.

“It was a more intense exposure as a result of the wind driving those toxins, even with our protective gear,” Gillotte said.

According to Gillotte, these types of urban wildfires could cause long-term health impacts for first responders similar to those from events like the destruction of the World Trade Center on Sept. 11, 2001. Already, officials from the Sacramento Metropolitan Fire District, the Sacramento Fire Department, and Los Angeles County have begun to test their firefighters for metal and chemical exposure, Gillotte said.

Meanwhile, as part of a separate study, Los Angeles city fire officials have also been looking at the health effects on its firefighters.

“We are very concerned and worried,” said Los Angeles Fire Department Capt. Kevin Frank. The LAFD has so far taken blood and urine samples of about 350 of its firefighters, as part of an ongoing nationwide study, funded by the Federal Emergency Management Agency, to look at firefighters’ biomarkers and exposure to cancer-causing substances. That study — which is different than the LA Fire Health Study and the one mentioned by Gillotte — includes more than 7,000 firefighters from across the country.

After the fires, Frank said, several firefighters who reported to Altadena and Pacific Palisades reported health issues, such as trouble breathing. Nadeau, who is working on the LA Fire Health Study, but not the FEMA-funded national study, noted that exposure to heavy metals can contribute to worse long-term health outcomes.

Firefighters already face higher levels of some illnesses, such as autoimmune diseases, asthma and some cancers, she said. Fire officials said the life expectancy of a firefighter is about 10 years lower than that of the average person.

The LA Fire Health study is still in its early stages. Nadeau says she and her colleagues plan to look for evidence of exposure to other heavy metals in addition to mercury and lead. “We’re going to be studying toxins that haven’t been studied” in firefighters before, she said.

Typically, the results of studies like these are not made public until they have been peer-reviewed and published by a scientific journal. Nadeau said the consortium decided to share some of the preliminary data early, hoping to help residents, civic leaders and first responders understand the impacts of the fires.

“You really want to know: ‘What’s in the air, what’s in the water, what’s in the ash that blew into my kitchen cabinet? Do I let my dog outside?’” she said. “All these questions were coming up and we thought, ‘We really need to serve the community.’” Indeed, while the initial findings will be focused on firefighters’ exposure, the team is also looking into residents’ exposure to heavy metals and chemicals.

Nadeau is also looking ahead: The information, she says, could help fire officials as they face the possibility of another similar fire by helping them better understand the source of the chemicals, how safety equipment was used during the fires, and the efficacy of that gear.

“I’d like to say this is the last of its kind, but we know it won’t be,” she said. “It’s not a matter of if, but a matter of when people undergo a fire like that again in L.A.”

Owners of fire-destroyed Palisades mobile home park seek to displace residents for development deal

Owners of fire-destroyed Palisades mobile home park seek to displace residents for development deal

For months, former residents of the Pacific Palisades Bowl Mobile Estates have feared the uncommunicative owners of the property would seek to displace them in favor of a more lucrative development deal after the Palisades fire destroyed the rent-controlled, roughly 170-unit mobile home park.

A confidential memorandum listing the Bowl for sale indicates the owners intend to do exactly that.

The memorandum, quietly posted on a website associated with the global commercial real estate company CBRE, says that the Palisades fire created a “blank canvas for redevelopment” at a site “ideally positioned for a transformative residential or mixed-use project.”

“I just thought, oh my god, this is so much propaganda and false advertising,” said Lisa Ross, a 33-year resident of the Bowl and a Realtor. “How can they even get away with printing this?”

Neither the current owners of the Bowl nor the real estate companies listed on the memorandum responded to requests for comment.

The memorandum describes the current single-family residential zoning as “favorable” for developers; however, the city and mobile housing law experts have painted a different picture.

“Multifamily and mixed-use development on this site is not allowed by existing zoning and land use regulations,” Mayor Karen Bass’s office said in a statement Wednesday, adding only low density single-family housing or reconstructing the mobile home park are currently allowed. “Mayor Bass will continue taking action and [work] with residents to restore the Palisades community.”

City Councilmember Traci Park also reiterated her focus on getting the mobile home park rebuilt and allowing residents to return, with a spokesperson noting she is not entertaining the potential for any rezoning efforts from a developer.

Zoning changes typically require a city council vote and are subject to the mayor’s approval or veto.

Beyond the zoning laws, the site is also currently governed by a state law requiring cities to preserve affordable housing along the coast and a city ordinance protecting mobile home residents against sudden displacement.

Spencer Pratt, a resident of the Palisades and an outspoken supporter of the neighborhood’s mobile home community, criticized the mayor and the owners in a statement to The Times. “It’s unfortunate that Karen Bass has not advocated for mobile home residents impacted by the fire,” he said, “and that the current owner of the Bowl is ignoring good faith offers from residents to buy the property.”

The mayor’s office disputed this, noting Bass recently led a delegation of Palisadians, including mobile home owners, to Sacramento to advocate for recovery. “Mayor Bass’ priority is getting every Palisadian home — single-family homeowners, town home owners, renters, mobile home owners.”

Bass also advocated for the federal government to include the Bowl in its debris cleanup efforts; however, the Federal Emergency Management Agency ultimately refused to include it, unlike other mobile home parks impacted by the Palisades fire. Its reasoning: It could not trust the owners to rebuild the park as affordable housing.

Court rulings over the years found the owners routinely failed to maintain the infrastructure and worked to replace the park with an “upscale resort community.” Residents also accused the owners of attempting to circumvent rent control regulations.

After the fire, it ultimately took more than 13 months to begin cleaning up the debris.

Ross said she approached the owners with independent mobile home park developers who were interested in buying the fire-destroyed lot and letting residents rebuild within months. She also approached the owners with a proposition that the former residents band together to buy the park. She heard nothing back.

“They don’t communicate,” Ross said. “It’s a feuding family. That’s also why we had so many problems with maintenance and with upgrades in the park.”

Pratt, who is running for mayor against Bass, also called on private developers like Rick Caruso to step in and save the Bowl. (Caruso’s team noted his rebuilding nonprofit is looking into how to help residents of the Bowl.)

Ross is a fan of Pratt’s proposition. “We need those kinds of people — we need Rick Caruso. That would be great,” Ross said. To sweeten the deal: “I’ll cook for him. I would make him all his favorite dishes.”

A virus without a vaccine or treatment is hitting California. What you need to know

A virus without a vaccine or treatment is hitting California. What you need to know

A respiratory virus that doesn’t have a vaccine or a specific treatment regimen is spreading in some parts of California — but there’s no need to sound the alarm just yet, public health officials say.

A majority of Northern California communities have seen high concentrations of human metapneumovirus, or HMPV, detected in their wastewater, according to data from the WastewaterScan Dashboard, a public database that monitors sewage to track the presence of infectious diseases.

A Los Angeles Times data analysis found the communities of Merced in the San Joaquin Valley, and Novato and Sunnyvale in the San Francisco Bay Area have seen increases in HMPV levels in their wastewater between mid-December and the end of February.

HMPV has also been detected in L.A. County, though at levels considered low to moderate at this point, data show.

While HMPV may not necessarily ring a bell, it isn’t a new virus. Its typical pattern of seasonal spread was upended by the COVID-19 pandemic, and its resurgence could signal a return to a more typical pre-coronavirus respiratory disease landscape.

Here’s what you need to know.

What is HMPV?

HMPV was first detected in 2001, according to the U.S. Centers for Disease Control and Prevention. It’s transmitted by close contact with someone who is infected or by touching a contaminated surface, said Dr. Neha Nanda, chief of infectious diseases and hospital epidemiologist for Keck Medicine of USC.

Like other respiratory illnesses, such as influenza, HMPV spreads and is more durable in colder temperatures, infectious-disease experts say.

Human metapneumovirus cases commonly start showing up in January before peaking in March or April and then tailing off in June, said Dr. Jessica August, chief of infectious diseases at Kaiser Permanente Santa Rosa.

However, as was the case with many respiratory viruses, COVID disrupted that seasonal trend.

Why are we talking about HMPV now?

Before the pandemic hit in 2020, Americans were regularly exposed to seasonal viruses like HMPV and developed a degree of natural immunity, August said.

That protection waned during the pandemic, as people stayed home or kept their distance from others. So when people resumed normal activities, they were more vulnerable to the virus. Unlike other viruses, there isn’t a vaccine for human metapneumovirus.

“That’s why after the pandemic we saw record-breaking childhood viral illnesses because we lacked the usual immunity that we had, just from lack of exposure,” August said. “All of that also led to longer viral seasons, more severe illness. But all of these things have settled down in many respects.”

In 2024, the national test positivity for HMPV peaked at 11.7% at the end of March, according to the National Respiratory and Enteric Virus Surveillance System. The following year’s peak was 7.15% in late April.

So far this year, the highest test positivity rate documented was 6.1%, reported on Feb. 21 — the most recent date for which complete data are available.

While the seasonal spread of viruses like HMPV is nothing new, people became more aware of infectious diseases and how to prevent them during the pandemic, and they’ve remained part of the public consciousness in the years since, August and Nanda said.

What are the symptoms of HMPV?

Most people won’t go to the doctor if they have HMPV because it typically causes mild, cold-like symptoms that include cough, fever, nasal congestion and sore throat.

HMPV infection can progress to:

  • An asthma attack and reactive airway disease (wheezing and difficulty breathing)
  • Middle ear infections behind the ear drum
  • Croup, also known as “barking” cough — an infection of the vocal cords, windpipe and sometimes the larger airways in the lungs
  • Bronchitis
  • Fever

Anyone can contract human metapneumovirus, but those who are immunocompromised or have other underlying medical conditions are at particular risk of developing severe disease — including pneumonia. Young children and older adults are also considered higher-risk groups, Nanda said.

What is the treatment for HMPV?

There is no specified treatment protocol or antiviral medication for HMPV. However, it’s common for an infection to clear up on its own and treatment is mostly geared toward soothing symptoms, according to the American Lung Assn.

A doctor will likely send you home and tell you to rest and drink plenty of fluids, Nanda said.

If symptoms worsen, experts say you should contact your healthcare provider.

How to avoid contracting HMPV

Infectious-disease experts said the best way to avoid contracting HMPV is similar to preventing other respiratory illnesses.

The American Lung Assn.’s recommendations include:

  • Wash your hands often with soap and water. If that’s not available, clean your hands with an alcohol-based hand sanitizer.
  • Clean frequently touched surfaces.
  • Crack open a window to improve air flow in crowded spaces.
  • Avoid being around sick people if you can.
  • Avoid touching your eyes, nose and mouth.

After rash of overdose deaths, L.A. banned sales of kratom. Some say they lost lifeline for pain and opioid withdrawal

After rash of overdose deaths, L.A. banned sales of kratom. Some say they lost lifeline for pain and opioid withdrawal

Nearly four months ago, Los Angeles County banned the sale of kratom, as well as 7-OH, the synthetic version of the alkaloid that is its active ingredient. The idea was to put an end to what at the time seemed like a rash of overdose deaths related to the drug.

It’s too soon to tell whether kratom-related deaths have dissipated as a result — or, really, whether there was ever actually an epidemic to begin with. But many L.A. residents had become reliant on kratom as something of a panacea for debilitating pain and opioid withdrawal symptoms, and the new rules have made it harder for them to find what they say has been a lifesaving drug.

Robert Wallace started using kratom a few years ago for his knees. For decades he had been in pain, which he says stems from his days as a physical education teacher for the Glendale Unified School District between 1989 and 1998, when he and his students primarily exercised on asphalt.

In 2004, he had arthroscopic surgery on his right knee, followed by varicose vein surgery on both legs. Over the next couple of decades, he saw pain-management specialists regularly. But the primary outcome was a growing dependence on opioid-based painkillers. “I found myself seeking doctors who would prescribe it,” he said.

He leaned on opioids when he could get them and alcohol when he couldn’t, resulting in a strain on his marriage.

When Wallace was scheduled for his first knee replacement in 2021 (he had his other knee replaced a few years later), his brother recommended he take kratom for the post-surgery pain.

It seemed to work: Wallace said he takes a quarter of a teaspoon of powdered kratom twice a day, and it lets him take charge of managing his pain without prescription painkillers and eases harsh opiate-withdrawal symptoms.

He’s one of many Angelenos frustrated by recent efforts by the county health department to limit access to the drug. “Kratom has impacted my life in only positive ways,” Wallace told The Times.

For now, Wallace is still able to get his kratom powder, called Red Bali, by ordering from a company in Florida.

However, advocates say that the county crackdown on kratom could significantly affect the ability of many Angelenos to access what they say is an affordable, safer alternative to prescription painkillers.

Kratom comes from the leaves of a tree native to Southeast Asia called Mitragyna speciosa. It has been used for hundreds of years to treat chronic pain, coughing and diarrhea as well as to boost energy — in low doses, kratom appears to act as a stimulant, though in higher doses, it can have effects more like opioids.

Though advocates note that kratom has been used in the U.S. for more than 50 years for all sorts of health applications, there is limited research that suggests kratom could have therapeutic value, and there is no scientific consensus.

Then there’s 7-OH, or 7-Hydroxymitragynine, a synthetic alkaloid derived from kratom that has similar effects and has been on the U.S. market for only about three years. However, because of its ability to bind to opioid receptors in the body, it has a higher potential for abuse than kratom.

Public health officials and advocates are divided on kratom. Some say it should be heavily regulated — and 7-OH banned altogether — while others say both should be accessible, as long as there are age limitations and proper labeling, such as with alcohol or cannabis.

In the U.S., kratom and 7-OH can be found in all sorts of forms, including powder, capsules and liquids — though it depends on exactly where you are in the country. Though the Food and Drug Administration has recommended that 7-OH be included as a Schedule 1 controlled substance under the Controlled Substances Act, that hasn’t been made official. And the plant itself remains unscheduled on the federal level.

That has left states, counties and cities to decide how to regulate the substances.

California failed to approve an Assembly bill in 2024 that would have required kratom products to be registered with the state, have labeling and warnings, and be prohibited from being sold to anyone younger than 21.

It would also have banned products containing synthetic versions of kratom alkaloids. The state Legislature is now considering another bill that basically does the same without banning 7-OH — while also limiting the amount of synthetic alkaloids in kratom and 7-OH products sold in the state.

“Until kratom and its pharmacologically active key ingredients mitragynine and 7-OH are approved for use, they will remain classified as adulterants in drugs, dietary supplements and foods,” a California Department of Public Health spokesperson previously told The Times.

On Tuesday, California Gov. Gavin Newsom announced that the state’s efforts to crack down on kratom products has resulted in the removal of more than 3,300 kratom and 7-OH products from retail stores. According to a news release from the governor’s office, there has been a 95% compliance rate from businesses in removing the products.

Newsom has equated these actions to the state’s efforts in 2024 to quash the sale of hemp products containing cannabinoids such as THC. Under emergency state regulations two years ago, California banned these specific hemp products and agents with the state Department of Alcoholic Beverage Control seized thousands of products statewide.

Since the beginning of 2026, there have been no reported violations of the ban on sales of such products.

“We’ve shown with illegal hemp products that when the state sets clear expectations and partners with businesses, compliance follows,” Newsom said in a statement. “This effort builds on that model — education first, enforcement where necessary — to protect Californians.”

Despite the state’s actions, the Los Angeles County Board of Supervisors is still considering whether to regulate kratom, or ban it altogether.

The county Public Health Department’s decision to ban the sale of kratom didn’t come out of nowhere. As Maral Farsi, deputy director of the California Department of Public Health, noted during a Feb. 18 state Senate hearing, the agency “identified 362 kratom-related overdose deaths in California between 2019 and 2023, with a steady increase from 38 in 2019 up to 92 in 2023.”

However, some experts say those numbers aren’t as clear-cut as they seem.

For example, a Los Angeles Times investigation found that in a number of recent L.A. County deaths that were initially thought to be caused by kratom or 7-OH, there wasn’t enough evidence to say those drugs alone caused the deaths; it might be the case that the danger is in mixing them with other substances.

Meanwhile, the actual application of this new policy seems to be piecemeal at best.

The county Public Health Department told The Times it conducted 2,696 kratom-related inspections between Nov. 10 and Jan. 27, and found 352 locations selling kratom products. The health department said the majority stopped selling kratom after those inspections; there were nine locations that ignored the warnings, and in those cases, inspectors impounded their kratom products.

But the reality is that people who need kratom will buy it on the black market, drive far enough so they get to where it’s sold legally or, like Wallace, order it online from a different state.

For now, retailers who sell kratom products are simply carrying on until they’re investigated by county health inspectors.

Ari Agalopol, a decorated pianist and piano teacher, saw her performances and classes abruptly come to a halt in 2012 after a car accident resulted in severe spinal and knee injuries.

“I tried my best to do traditional acupuncture, physical therapy and hydrocortisone shots in my spine and everything,” she said. “Finally, after nothing was working, I relegated myself to being a pain-management patient.”

She was prescribed oxycodone, and while on the medication, battled depression, anhedonia and suicidal ideation. She felt as though she were in a fog when taking oxycodone, and when it ran out, ”the pain would rear its ugly head.” Agalopol struggled to get out of bed daily and could manage teaching only five students a week.

Then, looking for alternatives to opioids, she found a Reddit thread in which people were talking up the benefits of kratom.

“I was kind of hesitant at first because there’re so many horror stories about 7-OH, but then I researched and I realized that the natural plant is not the same as 7-OH,” she said.

She went to a local shop, Authentic Kratom in Woodland Hills, and spoke to a sales associate who helped her decide which of the 47 strains of kratom it sold would best suit her needs.

Agalopol currently takes a 75-milligram dose of mitragynine, the primary alkaloid in kratom, when necessary. It has enabled her to get back to where she was before her injury: teaching 40 students a week and performing every weekend.

Agalopol believes the county hasn’t done its homework on kratom. “They’re just taking these actions because of public pressure, and public pressure is happening because of ignorance,” she said.

During the course of reporting this story, Authentic Kratom has shut down its three locations; it’s unclear if the closures are temporary. The owner of the business declined to comment on the matter.

When she heard the news of the recent closures, Agalopol was seething. She told The Times she has enough capsules of kratom for now, but when she runs out, her option will have to be Tylenol and ibuprofen, “which will slowly kill my liver.”

“Prohibition is not a public health strategy,” said Jackie Subeck, executive director of 7-Hope Alliance, a nonprofit that promotes safe and responsible access to 7-OH for consumers, at the Feb. 18 Senate hearing. “[It’s] only going to make things worse, likely resulting in an entirely new health crisis for Californians.”
