Los Angeles, California – New research conducted in southern California has revealed that residents living near superfund sites and major industrial polluters are at a higher risk of exposure to toxic PFAS “forever chemicals.” Furthermore, those living in areas with limited access to fresh food have been found to have increased levels of these dangerous compounds in their blood.
The study, which focused on hundreds of individuals, showed that people who live more than half a mile from a grocery store have 14% higher levels of PFOA and PFOS in their blood compared to those who live closer to a grocery store. Additionally, individuals residing within three miles of a superfund site have shown up to 107% higher levels of certain PFAS compounds in their blood.
Sherlock Li, a postdoctoral researcher at the University of Southern California, emphasized that the built environment in low-income neighborhoods plays a significant role in multiple PFAS exposure routes. He mentioned the challenges in finding solutions, as simply moving or using air filters, water filters, and consuming healthy food may not be feasible for everyone.
PFAS, known for their resistance to water, stains, and heat, have been linked to various health issues such as cancer, kidney disease, liver problems, immune disorders, birth defects, and more. The study also indicated that individuals living in neighborhoods with water contaminated by PFAS have 70% higher blood levels of PFOS and PFOA.
In neighborhoods with limited fresh food access, diet has been identified as a contributing factor to higher PFAS levels. Processed and fast foods that are commonly consumed in these areas tend to contain higher levels of PFAS, as they are often added to resist moisture and grease in food packaging.
The researchers emphasized the need for a holistic approach to reduce exposure to PFAS, addressing water, food, soil, and air contamination comprehensively. They also highlighted the importance of improving access to fresh foods through initiatives such as increasing the number of grocery stores or establishing community gardens.
The study participants living near former Air Force bases and a metal plating facility, now superfund sites contaminated with PFAS, showed higher blood levels of PFAS. The authors suggested that the elevated PFAS blood levels around these sites may be attributed to air pollution, as PFAS can become airborne and be ingested through breathing or dust ingestion.
Moving forward, researchers hope that the government will take action based on the analysis to reduce pollution at the source, ultimately protecting the health of individuals exposed to PFAS in their communities.
