Recent research has shed light on the increased exposure to toxic PFAS “forever chemicals” in certain US neighborhoods. Those residing near superfund sites, major industrial polluters, or areas lacking access to fresh food tend to have higher levels of these harmful compounds in their bloodstream.
A study conducted in southern California revealed that individuals living more than half a mile away from a grocery store have 14% higher levels of PFOA and PFOS in their blood compared to those who live closer to one. Similarly, residents within three miles of superfund sites showed up to 107% higher levels of certain compounds associated with PFAS exposure.
Sherlock Li, a postdoctoral researcher at the University of Southern California, emphasized how environmental factors in low-income neighborhoods contribute to multiple routes of PFAS exposure. Addressing this issue poses challenges as simple solutions like relocation or using filters may not be feasible for everyone.
PFAS are persistent chemicals known for their adverse health effects such as cancer and immune disorders. The study also linked contaminated water sources with elevated blood levels of PFOS and PFOA. Diet plays a role too, with processed foods containing higher levels of PFAS commonly found in neighborhoods with limited access to fresh produce.
While efforts are being made to reduce the use of PFAS in food packaging, imported products may still contain these chemicals. Improving access to fresh foods through more grocery stores or community gardens could help lower PFAS exposure levels.
Some participants in the study lived near former Air Force bases and metal plating facilities now designated as superfund sites due to PFAS contamination. The findings underscore the need for comprehensive action by authorities to address this pressing public health concern.
