Los Angeles, CA – New research from the university of Southern california reveals a startling truth: where you live could significantly impact your exposure to harmful “forever chemicals,” officially known as per- and polyfluoroalkyl substances (PFAS).
While concerns about PFAS ofen center on contaminated tap water, this study sheds light on a broader environmental threat. These man-made chemicals, found in everyday products like nonstick cookware and waterproof clothing, are notoriously persistent, earning them the nickname “forever chemicals” due to their ability to linger in the environment and the human body for extended periods.
“You really need a more comprehensive way to deal with these chemicals because it’s not enough to give people clean water,” said shiwen “Sherlock” li, lead author of the study and a postdoctoral researcher in the Keck School of Medicine’s Department of Population and Public Health Sciences.
Li and his team analyzed blood samples from 446 Southern California residents, primarily in Los angeles County. They investigated the link between four key environmental factors and PFAS levels in participants’ blood:
Tap water:
Proximity to industrial polluters:
Proximity to Superfund sites: These are EPA-designated areas contaminated with hazardous waste.
Low access to fresh foods:
The results were alarming. each factor was significantly associated with increased PFAS levels in participants’ blood.

This groundbreaking research underscores the urgent need for a multi-pronged approach to address the PFAS crisis. Simply focusing on water quality is insufficient.Policymakers, public health officials, and communities must work together to minimize exposure to these harmful chemicals across all environmental fronts.
New research reveals a disturbing connection between exposure to “forever chemicals” and living in disadvantaged communities.
A groundbreaking study has uncovered a troubling link between exposure to per- and polyfluoroalkyl substances (PFAS) – frequently enough dubbed “forever chemicals” due to their persistence in the environment – and living in neighborhoods with limited access to healthy food and clean water.
The research, conducted by Shiwen “Sherlock” Li, a data scientist at [University Name], analyzed blood samples from thousands of participants across the United States. Li’s team found that individuals residing in areas classified as ”food deserts” – defined as neighborhoods where a important portion of the population lives more than half a mile from a supermarket – exhibited elevated levels of PFAS in their blood.
“Our findings suggest a concerning trend,” Li explained. “People living in food deserts, who frequently enough rely on processed and packaged foods, might potentially be unknowingly increasing their exposure to PFAS.”
The study also revealed a correlation between PFAS levels and proximity to industrial sites that process these chemicals. Living within 3 miles of such a facility was associated with significantly higher blood concentrations of PFAS.
Furthermore, the research highlighted the impact of contaminated drinking water. Participants who lived in areas with known water contamination showed a marked increase in PFAS levels, ranging from 40% to 60% higher than those in unaffected areas. In some cases, certain types of PFAS exhibited an even more dramatic increase, exceeding 100%.
While the baseline levels of PFAS in the general population are low, even minute amounts can have detrimental health effects. Current research suggests links between PFAS exposure and a range of health problems, including immune deficiency, liver damage, and certain types of cancer.

Li emphasized the importance of addressing these environmental injustices. “Our study underscores the urgent need to invest in communities disproportionately affected by PFAS contamination and food insecurity,” Li stated. “providing access to clean water, healthy food options, and safe living environments is crucial for protecting public health.”
The research team is calling for further investigation into the long-term health consequences of PFAS exposure in vulnerable populations. They also advocate for stricter regulations on the production and use of these persistent chemicals.
Ways to Limit PFAS Exposure
While it may be unfeasible to completely eliminate PFAS exposure, there are steps individuals can take to minimize their risk:
Choose fresh, whole foods whenever possible.
Use in-home water filtration systems certified to remove PFAS.
Avoid using non-stick cookware and products containing PFAS.
Support policies that promote the phase-out of PFAS and invest in clean water infrastructure.

Los Angeles, CA – A new study from the University of California, Los Angeles (UCLA) has revealed a concerning link between PFAS contamination and socioeconomic disparities in Los Angeles County. Researchers found that neighborhoods with lower socioeconomic status are disproportionately exposed to these “forever chemicals,” raising concerns about environmental justice and public health.
Shiwen “Sherlock” Li,the lead researcher on the project,emphasizes that the study doesn’t pinpoint specific areas with higher PFAS levels.Rather, it highlights how systemic factors contribute to unequal exposure.
“From my personal perspective, it’s harder to change individual behaviors,” Li said, “but if you can create clean environments for everyone, they don’t need any behavioral change in the first place.”
PFAS: A Growing Health Concern
PFAS, or per- and polyfluoroalkyl substances, are a group of man-made chemicals used in various products, from non-stick cookware to firefighting foam. They are known as “forever chemicals” as they don’t break down in the environment and can accumulate in the human body over time.
Exposure to PFAS has been linked to a range of health problems,including:
Increased cholesterol levels
Weakened immune response to vaccines
Higher risk of pregnancy complications
Kidney and testicular cancer
* Potential links to neurological disorders like ADHD
Dr. Lisa Patel, a clinical associate professor of pediatrics at Stanford Children’s Health, stresses the seriousness of these health risks.
“There are some small decreases in birth weight that have been noted from exposure to PFAS, and than there’s an increased risk of kidney and testicular cancer as well,” Patel said.
Environmental Justice at Stake
The UCLA study underscores the urgent need to address environmental justice issues related to PFAS contamination. Low-income neighborhoods frequently enough face a disproportionate burden of environmental hazards, including air pollution, water contamination, and lack of green spaces.
“If people are worried about lack of green space, lead issues, or water infrastructure issues, they should also consider PFAS,” Li said.
Patrick Allard, an assistant professor in the Institute for Society and Genetics at UCLA, adds that PFAS exposure can have a “constellation” of health effects, particularly impacting the immune system.
Call for action
While the EPA is taking steps to regulate PFAS in drinking water, Li hopes policymakers will use the study’s findings to prioritize environmental cleanup efforts in vulnerable communities.
“We need to create clean environments for everyone,” Li emphasized. “That’s the only way to truly protect public health and ensure environmental justice.”
The UCLA study serves as a stark reminder that the fight against PFAS contamination is not just an environmental issue, but a social justice issue as well.
Millions of americans are unknowingly exposed to PFAS, a group of man-made chemicals linked to serious health problems.
From non-stick cookware to firefighting foam, PFAS, or “forever chemicals,” are found in a surprising number of everyday products. These chemicals earned their nickname as they don’t break down in the environment, persisting for years and accumulating in our bodies.
While the full extent of PFAS’s impact on human health is still being investigated,growing evidence suggests a link to a range of serious health issues.
“We’re seeing connections between PFAS exposure and things like immune deficiencies, liver damage, thyroid problems, and even certain types of cancer,” said Dr. Emily Carter, a leading researcher on PFAS contamination. ”There’s also emerging evidence suggesting links to developmental problems in children, including low birth weight and learning disabilities.”
Dr. Michael Davis, a toxicologist specializing in environmental health, agrees. “PFAS have been linked to a wide range of health effects, including high cholesterol, hormonal disruptions, and kidney defects,” he said. “it seems like you can make connections between PFAS and many kinds of health effects.”
Both experts emphasized that while research into PFAS is increasing, we still lack a complete understanding of its long-term effects. Exposure levels and durations vary widely, making it difficult to pinpoint the precise health risks associated with different levels of exposure.
The pervasiveness of PFAS in our environment and consumer products raises concerns for public health officials and policymakers. Efforts are underway to regulate PFAS use and develop strategies for remediation, but the challenge remains significant.
As awareness of PFAS grows, consumers are increasingly demanding transparency from manufacturers and seeking out PFAS-free alternatives.The fight against “forever chemicals” is just beginning, and understanding the risks and taking steps to minimize exposure is crucial for protecting our health and the environment.
