Researchers Shocked at Daily Level of Plasticizers in California's Air
We live in a world where it is virtually impossible to escape plastics and their associated chemicals.
New evidence suggests that in southern California, the average urban resident’s exposure to plasticizers – the substances used to soften plastics and make them more flexible – is “through the roof”.
“No matter who you are, or where you are, your daily level of exposure to these plasticizer chemicals is high and persistent,” concludes toxicologist David Volz from the University of California, Riverside (UCR).
“They are ubiquitous.”
While not all of these plasticizers are known to be toxic, several are linked to serious health issues.
Just recently, the California State Legislature moved to ban one of these chemical compounds, DEHP, from use in IV bags and medical tubing. The state warns that DEHP (di (2-ethylhexyl) phthalate) can increase the risk of cancer, harm the reproductive system, and affect child development.
In California, DEHP has been banned in children’s products at certain concentrations since 2009.
The new research, however, suggests residents in the southern region of the state continue to be exposed to this chemical and others like it at high concentrations.
The findings come from experiments conducted in 2019 and 2020. A total of 137 students at UCR were equipped with silicone wristbands, which they then wore for five days straight as they went about their usual lives.
Retrieving the bands, researchers at UCR and Duke University looked for 10 known plasticizers that the material might have absorbed from the environment. To their surprise, they uncovered an astonishing concentration of possibly dangerous pollutants.
“The levels of these compounds are through the roof,” says Volz. “We weren’t expecting that.”
But similar exposure levels have been found on the east coast of the US, too.
Of the total mass of plasticizers absorbed by the bracelets in southern California, between 94 and 97 percent were attributed to DiNP, DEHP, and a new type called DEHT.
Along with DEHP, the state of California has also determined that DiNP (di-isononyl phthalate) may increase the risk of cancer.
Like most of today’s plasticizers, DiNP and DEHP belong to a family called phthalates – found in food packaging, vinyl, cosmetics, and household products galore.
Phthalates can be ingested, absorbed through the skin, or inhaled. They have a short life in the human body, and yet they are now found in the urine of most Americans with largely unknown health effects.
DEHT is not a phthalate. It was introduced as a safer alternative, but researchers say “little is known about the potential toxicity of DEHT in human-relevant model systems.”
“Overall, our findings raise concerns about chronic DiNP, DEHP, and DEHT exposure in urban, population-dense regions throughout California,” warns the team.
And they aren’t the only ones expressing concern. The US Environmental Protection Agency (EPA) is currently evaluating the toxicity of DEHP, DiNP, and other phthalates in light of new evidence, which suggests these chemicals are probably carcinogenic.
A preliminary draft of the EPA review determines that DiNP causes liver damage and could cause cancer at higher levels of exposure.
“EPA is concerned about phthalates because of their toxicity and the evidence of pervasive human and environmental exposure to these chemicals,” reads the agency site on phthalates.
“Phthalates are used in many industrial and consumer products, many of which pose potentially high exposure. Phthalates have been detected in food and also measured in humans.”
The study was published in Environmental Research.

Mother, daughter found ‘alive and well’ after going missing on Southern California hiking trail
A mother and daughter who went missing after going for a hike on a difficult trail in San Bernardino County’s San Gorgonio Wilderness have been found “alive and well,” the sheriff’s department announced Friday.
The San Bernardino County Sheriff’s Department told KTLA they were uninjured and “walked out on their own.”
Krystal Meyers, 41, and her daughter Alexis Meyers Martinez, 21, were hiking on the Vivian Creek Trail Thursday but didn’t return, according to the San Bernardino County Sheriff’s Department.
They were last known to be at the 10,300-foot elevation mark above the High Creek switchbacks at 11 a.m., according to the San Gorgonio Search and Rescue team.
The Vivian Creek Trail is widely considered one of the more strenuous and hazardous routes in the San Gorgonio Wilderness.
The U.S. Forest Service says it’s the shortest and steepest route to the summit of Mount San Gorgonio and requires experienced mountaineering skills.
Officials did not provide any further details about the circumstances surrounding their disappearance.

California Highway Patrol work to keep drivers safe during holiday weekend enforcement
BAKERSFIELD, Calif. (KBAK/KBFX) — The California Highway Patrol is urging drivers to stay focused on the road as they head out for Fourth of July celebrations.
The holiday weekend can be a dangerous time on our roads as millions of drivers are expected to travel.
CHP Officer Jorge Toro joined Eyewitness News Mornings to share how drivers can stay safe behind the wheel.
Officer Toro also highlighted the importance of sober driving over the holiday.

California returns stretch of coast to Indigenous tribes. ‘This is beyond huge’
California is returning a stretch of rugged Mendocino County coast to the Indigenous nations whose ancestors once stewarded its shores.
State transportation officials recently approved the transfer of Blues Beach and the surrounding bluffs to Kai Poma, a nonprofit founded by representatives of the Sherwood Valley Band of Pomo Indians, Round Valley Indian Tribes and Coyote Valley Band of Pomo Indians.
The transfer of 136 acres just south of the community of Westport will mark the first time land managed by the California Department of Transportation has been returned to Indigenous tribes.
“This is beyond huge,” said J. Carlos Rivera, tribal chairman of the Sherwood Valley Band of Pomo Indians. “It’s enormous from our tribal perspective that we are basically obtaining the land that our people once lived on before colonization.”
California purchased the swath of rocky cliffs and windswept shoreline in the 1960s to expand the construction of Highway 1 and create a scenic viewpoint for highway travelers, according to a California Coastal Commission report.
More recently, public access has been largely unregulated, and summer weekends and holidays have drawn large groups who camp and party on the beach, at times driving through sensitive areas, damaging cultural sites and leaving behind trash, the report states.
Kai Poma plans to conduct cultural and archaeological resource studies and environmental surveys and then prepare a resource management plan for the property, according to planning documents. The nonprofit and the Coastal Commission have drafted a public access management plan that states the land will be open from sunrise to sunset.
Rivera described the entire property as a sacred site. The coastal waters are used by tribal people for seaweed and abalone gathering, and the shores host youth cultural camps, he said. “Protecting the land, it has a deeper meaning for us because we’re connected to the land,” he said.
The effort to acquire the land took years — and required a change in state law. Caltrans lacked the ability to transfer land to tribal governments until 2021, when Gov. Gavin Newsom signed a bill sponsored by state Sen. Mike McGuire (D-Healdsburg) that enabled the transfer, according to a news release issued at the time. The law also bars commercial activity on the property and requires public access be maintained.
“With 136 acres now officially transferred into tribal stewardship, one of the most spectacular stretches of the Mendocino Coast will be forever protected,” McGuire said in a statement.
“This agreement, the first of its kind in California, gives these three dynamic Native American tribes the rightful opportunity to reclaim sacred lands and cultural traditions on this special piece of earth. And it’s about damn time.”
The land transfer cleared its last regulatory hurdle June 26 with the approval by the California Transportation Commission, said Neil Thapar, an attorney who works as an advisor and legal consultant to Kai Poma. Caltrans staff will next record the deed transferring the title from the state of California to Kai Poma, which is expected to happen any day, he said.
