Toxic Burden: American Communities Unequal Before "Forever Chemicals"
A new study reveals a stark reality for residents of countless communities across the U.S.: where you live can have a significant impact on your exposure to toxic "forever chemicals" known as PFAS. This alarming revelation comes from research focusing on Southern California, but the implications are felt nationwide.
Researchers at the University of Southern California examined hundreds of residents and found a clear link between proximity to pollution sources and elevated levels of PFAS in the bloodstream.
"It’s a difficult question because you can’t tell people to just move or to buy air filters and water filters and eat healthy food,” said Sherlock Li, a postdoctoral researcher at USC.
Invisible Threats, Tangible Dangers
Living within a three-mile radius of a Superfund site—a location contaminated with hazardous substances—increases PFAS levels by up to 107% in some individuals, the study found. Similarly, those residing near industrial facilities using PFAS showed significantly higher blood concentrations compared to other participants.
Even access to fresh food became a critical factor. Individuals living more than half a mile from a grocery store had 14% higher levels of two common PFAS compounds—PFOA and PFOS—likely due to reliance on processed and fast foods known to be PFAS-laden.
“We’re hoping the government will see the analysis and take action … because it’s more cost effective to reduce pollution at the source," Li emphasizes.
The Ubiquitous Threat of PFAS
PFAS, used in countless everyday products due to their water and stain-resistant properties, have earned the ominous moniker "forever chemicals" because they don’t naturally degrade. They’ve been linked to a horrifying array of health problems, including cancer, kidney and liver disease, immune disorders, birth defects, and more.
While the FDA took a step towards reducing exposure by banning the use of PFAS in paper food packaging produced in the U.S. last year, imported wrappers and plastic containers could still pose a threat.
A Multifaceted Problem Requiring Holistic Solutions
The study highlights how multiple pathways contribute to PFAS exposure in vulnerable communities. Contamination of drinking water, air pollution emanating from contaminated sites, and the widespread presence of PFAS in food packaging all play a role.
Addressing this complex issue requires a multipronged approach.
"We need to be more holistic to reduce water, food, soil air exposure – all of them,” Li stated.
Solutions must go beyond individual responsibility and delve into structural changes.
Increased access to fresh, healthy food through community gardens and grocery stores in underserved areas could help mitigate exposure. Strengthening environmental regulations to curb pollution at its source and mandating comprehensive cleanup of contaminated sites are also essential steps toward safeguarding public health.
The study serves as a sobering reminder that the burden of environmental toxins often falls disproportionately on those least equipped to bear it.
It underscores the urgent need for policy changes and community action to break free from the legacy of forever chemicals.
## Toxic Burden: Unequal Exposure to “Forever Chemicals”

**With Sarah Jenkins, Senior Editor, WorldTodayNews.com**
**SJ:** Dr. Li, thank you for joining us today. Your groundbreaking research on PFAS exposure in Southern California has painted a disturbing picture of unequal vulnerability to these “forever chemicals.” can you elaborate on your findings?
**SL:** Certainly. Our study looked at hundreds of Southern California residents and measured their blood levels of PFAS. We found a clear correlation: those living closer to known sources of PFAS contamination, such as industrial sites and military bases, had significantly higher PFAS concentrations in their blood. This suggests that geographical location plays a critical role in determining individual exposure risk.
**SJ:** This research is alarming,especially considering the potential health impacts of PFAS.Can you tell us more about these risks?
**SL:** PFAS are known as “forever chemicals” because they don’t break down in the environment. They can accumulate in our bodies over time, leading to a range of health problems. These include immune deficiency, liver damage, thyroid disruption, and even certain types of cancer. Children are notably vulnerable to the harmful effects of PFAS.
**SJ:** Your study focused on Southern California, but you’ve indicated these findings have nationwide implications. Why is that?
**SL:** PFAS contamination is a widespread problem in the US and beyond.These chemicals have been used in countless products and applications for decades, meaning they’ve permeated our soil, water, and even the air we breathe. While our study focused on Southern California, the pattern of unequal exposure is likely mirrored in communities across the country.
**SJ:** What can be done to address this problem?
**SL:** This is a complex issue requiring a multi-faceted approach. We need stricter regulations on PFAS manufacturing and use, robust cleanup efforts at contaminated sites, and increased public awareness about the risks.
Individuals can take steps to reduce their exposure, such as using filtered water, avoiding non-stick cookware, and supporting companies committed to PFAS-free products.
**SJ:** The solutions you proposed seem elaborate and long-term. What message do you have for those facing immediate concerns about PFAS exposure in their communities?
**SL:** It’s a challenging question because you can’t tell people to simply move or to buy air filters and water filters and eat healthy food.
These are complex issues rooted in systemic inequalities.The first step is awareness.knowing your risk allows you to make informed decisions. Advocate for testing in your community, demand clarity from local authorities, and support policies that prioritize public health over corporate interests. Finding solutions requires a collective effort, and it starts with each of us raising our voices.
**SJ:** Dr. Li, thank you for yourTime and your insights. This is a critical issue, and your work is bringing much-needed attention to the unequal burden of “forever chemicals.”
**SL:** Thank you for having me.
