Could your car make you sick? Study highlights potentially cancerous toxins in vehicles
Americans may be breathing in cancer-causing chemicals while driving, recent research suggests.
A study published in the journal Environmental Science & Technology has sparked discussions about the potentially harmful toxins that could be lurking in the cabins of vehicles.
“Certainly the indoor air quality can cause health symptoms,” Dr. Ken Speath, M.D., the division chief and medical director for occupational and environmental medicine at Northwell Health on Long Island, New York, told Fox News Digital.

It is important to be mindful of what you’re breathing in at home, at the office, at school and even in cars, according to Speath, who was not involved in the study.
“There can be situations where levels of harmful chemicals get high enough to potentially cause health harms,” he said.

“A car is a closed small space — so whatever is in the air is certainly going to be breathed in.”
Research reveals ‘harmful chemicals’
The peer-reviewed study looked at 101 owned vehicles in the U.S., model year 2015 or newer.
The researchers concluded that harmful flame-retardant chemicals — including those suspected of potentially causing cancer and some neurological issues — may be polluting the air inside vehicles.
DRIVING DANGERS: 9 TOP DISTRACTIONS THAT CONTRIBUTE TO ACCIDENTS, ACCORDING TO EXPERTS
“Flame retardant chemicals, which are intentionally added to vehicle interiors to meet flammability standards, are released into the cabin air from the materials to which they were applied,” lead author Rebecca Hoehn, a scientist at Duke University, told Fox News Digital.
“People in these vehicles may be exposed to these chemicals.”
Seat foam was the only material the researchers measured, Hoehn said, but other interior materials could also contain the chemicals.

“Considering the average driver spends about an hour in the car every day, this is a significant public health issue,” Hoehn warned.
“It’s particularly concerning for drivers with longer commutes, as well as child passengers, who breathe more air pound for pound than adults.”
The chemicals detected in the car cabins included a flame retardant called tris (1-chloro-isopropyl) phosphate (TCIPP), which is currently being investigated as a potential carcinogen by the U.S. National Toxicology Program.
“Considering the average driver spends about an hour in the car every day, this is a significant public health issue.”
Other flame retardants — tris (1, 3-dichloro-2-propyl) phosphate (TDCIPP) and tris (2-chloroethyl) phosphate (TCEP) — were also detected.
These are “two Californian Proposition 65 carcinogens linked to neurological and reproductive harms,” according to a press release.
Higher concentrations of the flame retardants were found during warmer weather.
“We found that the same cars, sampled in both winter and summer, had higher concentrations of flame retardants in the cabin air during the warm summer months,” Hoehn told Fox News Digital.
Flame retardants are added to vehicles to meet the National Highway Traffic Safety Administration Federal Motor Vehicle Safety Standard, which mandated their use in the 1970s. (iStock)
Flame retardants are added to vehicles to meet the National Highway Traffic Safety Administration Federal Motor Vehicle Safety Standard (FMVSS 302), which mandated their use in the 1970s, the release stated.
Flame retardants have been the “focus of concern for some time,” Speath told Fox News Digital.
More information is needed to determine the health risks these chemicals pose in humans, he said.

“A number of these have been demonstrated in studies to have health harms in animals,” he said.
“That doesn’t necessarily mean that would be true for humans, but it raises that possibility, so we need to study these chemicals more in relation to their effects on humans.”

Emanuela Taioli, M.D., PhD, the director of the Institute for Translational Epidemiology at Icahn School of Medicine at Mount Sinai in New York City, was also not part of the study, but shared her reactions.
“This is a very relevant finding, since it may prompt changes in cars’ upholstery, as well as in other parts of the car where there is foam,” she told Fox News Digital via email.
“We also want to know more about this finding and monitor whether it is replicated by other investigators.”
Other sources of toxins
Stephen Showalter, a home inspector and indoor environmental air consultant with Showalter Property Consultants in Maryland, said he typically interviews clients about their history of illness, then tests for potential sources of sickness in buildings, cars, RVs and boats.
Mold is a common culprit when it comes to health issues triggered by one’s environment, he said in an interview with Fox News Digital.
TOXIC CHEMICAL POISONING: HAVE YOU BEEN AFFECTED? HOW TO KNOW
Dr. Daniel Johns, a member of the International Society of Environmentally Acquired Illnesses and a chiropractor who practices in Annapolis, Maryland, echoed Showalter’s concerns about mold-related health issues.
Johns also cautioned that cars can be a daily source of mold exposure.
“Any water that leaks from a window, sunroof or convertible can get into the carpet and cause mold growth,” he said during an interview with Fox News Digital.

“Mold can start growing on a wet surface within 24 to 48 hours.”
For families with small children, spilled sippy cups could play a role when it comes to mold in cars, Johns warned.
“The water seeps into the upholstery and doesn’t get noticed or properly dried out, and the whole seat can become moldy,” he said.
“Mold can start growing on a wet surface within 24 to 48 hours.”
“Every time you sit on the seat, it releases a mold spore cloud into the car. Once that happens, you can’t clean it away. The upholstery must be removed and replaced.”
The impact of these potentially harmful pollutants can vary from one person to the next, experts told Fox News Digital.

People metabolize chemicals and toxins in different ways, according to Taioli.
“Metabolism happens through enzymes that the body produces,” he said.
“Each of us has a different genetic profile that defines our metabolic capacity. As a consequence, the same amount of toxin may be metabolized better/faster by some, and worse/slower by others.”
Tips for ensuring safe interiors
While further research on car-borne chemicals is needed, experts say people can take measures to limit exposure.
“People may be able to reduce their exposure by ventilating their cars,” Hoehn advised.
“For example, rolling down the windows to let out contaminated air, or pulling in fresh air with climate control systems, should reduce concentrations.
“Ultimately, reducing the amount of flame retardants added to vehicles in the first place would provide the greatest reduction in exposure risk.”
Controlling your vehicle’s cabin temperature may also reduce exposure, she added.
“Parking in a garage or shade instead of full sun may reduce the cabin temperature and limit the extent of flame retardant release,” Hoehn said.
The researchers also called for action from regulatory agencies and vehicle manufacturers.

“Ultimately, reducing the amount of flame retardants added to vehicles in the first place would provide the greatest reduction in exposure risk,” Hoehn noted.
“If flammability standards for vehicles could be revised to meet fire safety guidelines without the use of added flame retardants, risk of flame retardant exposure from personal vehicles could be greatly reduced.”
To prevent mold in a vehicle, experts recommend keeping your windows up when it rains or snows to prevent water from permeating the carpet or fabric. (iStock)
Having your car’s air quality and surfaces tested is one way to reduce the risk of exposure to allergens, toxins and chemicals, experts told Fox News Digital.
To prevent mold in a vehicle, Showalter recommends keeping your windows up when it rains or snows to prevent water from permeating the carpet or fabric.
He also cautioned about leaky air conditioners, which can foster mold growth in vehicles, and about leaving wet items in the car.
Lastly, before buying a used car, he said it is important to check the vehicle’s history to make sure it doesn’t have flood damage, which can lead to mold and other issues.
If you think you are experiencing illness due to chemical exposure in your car, home or office, it’s best to see a health care professional to discuss your symptoms.
Fox News Digital reached out to several major car companies for comment.

An American woman who may have been exposed to hantavirus on board the MV Hondius cruise ship is now being forced to quarantine at a facility in Omaha, Nebraska.
Angela Perryman, 47, anticipated having to stay at the National Quarantine Unit for a short time after arriving last week, but on Monday she was served with a federal order to remain quarantined for at least two more weeks, she shared with The New York Times.
The order mandates that Perryman remains in the facility until May 31, which would be a total of 21 days after her arrival. Officials told her that any attempts to leave could result in law enforcement involvement, she said.

The woman shared that she received a negative hantavirus test result and is not experiencing symptoms. However, she said she did briefly speak with a passenger who later died from the disease.
The federal order, which the passenger shared with the Times, states that it could “constitute a probable source of infection to other people” if Perryman were to leave the facility to travel to another state.

Seven other passengers who left the ship and returned home prior to the outbreak’s discovery are being monitored by their state and local health departments, per the CDC.
“The reason they’re watching these passengers so carefully is that the incubation period can be very long — up to six weeks — and when symptoms hit, patients can deteriorate very rapidly,” Dr. Marc Siegel, Fox News senior medical analyst, said during a recent episode of “The Faulkner Focus.”

“This is not something that spreads easily like COVID, but because the Andes strain has rare person-to-person transmission, public health officials are being extremely cautious,” he added.
At least three people linked to the outbreak aboard the ship have died, while additional passengers have been sickened, according to the World Health Organization.
“This is not something that spreads easily like COVID, but because the Andes strain has rare person-to-person transmission, public health officials are being extremely cautious.”
The federal government last imposed a large-scale quarantine order in January 2020, when nearly 200 Americans evacuated from Wuhan, China, the epicenter of the COVID-19 outbreak. They were required to remain in isolation for two weeks at the March Air Reserve Base in Riverside County, California, per the CDC.

FDA fast-tracks pancreatic cancer drug daraxonrasib
Family and emergency medicine physician Dr. Janette Nesheiwat discusses how artificial intelligence could help detect pancreatic cancer earlier and the FDA fast-tracking the drug daraxonrasib on ‘Fox Report.’
NEWYou can now listen to Fox News articles!
A new drug for pancreatic cancer is showing promise in early testing.
Daraxonrasib is a daily pill designed to block cancer signals linked to the RAS gene. It has now finished an early-stage clinical trial — the first time it was tested in people — to evaluate both its safety and effectiveness.
The clinical trial, led by the Dana-Farber Cancer Institute and published in The New England Journal of Medicine, tested the drug in 168 patients with advanced pancreatic cancer whose tumors had mutations in the RAS gene. All study participants had previously received at least one chemotherapy treatment.
6 THINGS TO KNOW ABOUT PANCREATIC CANCER AFTER FORMER SENATOR’S DIAGNOSIS
The drug is designed to block multiple active cancer signals that help tumor cells grow. This is especially important because more than 90% of pancreatic cancers carry these harmful mutations, researchers said.
Existing and older drugs that target RAS mutations only work on certain types that are uncommon in pancreatic cancer, such as KRAS mutations.

At the 300-milligram dose — the amount that will be used in larger phase 3 trials — about 30% of patients saw a positive response, researchers noted. Overall, about 90% of patients had their cancer either shrink or stop getting worse.
DEADLY CANCER TYPE LINKED TO OBESITY AND HIGH STRESS LEVELS
There were some side effects reported — most commonly rash, mouth inflammation, nausea and diarrhea.
Lead investigator Dr. Brian Wolpin, director of the Hale Family Center for Pancreatic Cancer Research at Dana-Farber, commented in a press release statement that this development could change the future of cancer care.
About 90% of patients treated with the drug experienced disease control, meaning their cancer was reduced or stabilized. (iStock)
“If supported by data from future clinical trials, daraxonrasib would be a targeted therapy relevant to nearly all patients with advanced pancreatic cancer,” he said.

“This trial provides the first published data showing the safety and broad activity of a RAS(ON) multi-selective inhibitor in pancreatic cancer,” Wolpin went on. “If it proves effective in larger clinical trials, it would signify a substantial shift in how this disease is treated.”
In an interview with Fox News Digital, the researcher claimed that daraxonrasib represents “one of the most promising therapy advances we’ve seen in pancreatic cancer.”

This is especially significant since pancreatic cancer has had “very few effective therapies” in the past, Wolpin noted.
“The study also showed disease control in approximately 90% of patients with metastatic pancreatic cancer, which is extremely exciting,” he added.
The study does not prove daraxonrasib is superior to standard treatment of chemotherapy, researchers noted. (iStock)
Wolpin noted that while side effects were common, most patients were able to tolerate treatment with “supportive care measures, and very few patients needed to stop therapy due to side effects.”
As this was a phase 1/2 study, it does not “definitively prove” the superiority of daraxonrasib compared to chemotherapy, Wolpin added.

“The study did not include a randomized control arm that directly compared daraxonrasib with chemotherapy,” he said. “That being said, the results for daraxonrasib looked substantially better than what we have seen in prior clinical trials of chemotherapy in patients with previously treated metastatic pancreatic cancer.”
It also remains unclear how the drug may perform earlier in the disease, as the trial included patients who had already received prior treatments.
“Additional research is needed to determine how best to sequence or combine therapies to provide the most durable responses and cures,” the lead investigaror sid. (iStock)
For patients and families affected by pancreatic cancer, Wolpin noted that daraxonrasib signals “real momentum” toward effective treatments, but it is still investigational and is not a cure.
“Pancreatic cancer remains a challenging disease, and additional research is needed to determine how best to sequence or combine therapies to provide the most durable responses and cures,” he said.

Brian Slomovitz, director of gynecologic oncology and co-chair of the Cancer Research Committee at Mount Sinai Medical Center in Miami Beach, applauded this development in a separate interview with Fox News Digital.
“We are anxiously awaiting the upcoming plenary presentation of RASolute 302 at the ASCO meeting later this month,” said the expert, who was not involved in the study. “Greater than 90% of pancreatic cancers have activation of kRAS, which is a major factor in the development and progression of these cancers.”
“Doubling the survival time in pretreated patients is unprecedented.”
“If the full dataset results that will be reported later this month confirm what was earlier released, I believe this will be one of the most important breakthroughs in all solid tumors,” Slomovitz went on. “Doubling the survival time in pretreated patients is unprecedented.”

The doctor added that the “magnitude of benefit” could “reshape the treatment landscape” and “establish a new standard of care.”
“We will need to evaluate the full dataset for efficacy and safety,” Slomovitz added. “I am more than cautiously optimistic, and I am truly excited for our patients and their families that suffer from this dreadful disease.”
