A recent study revealed alarming levels of PFAS chemicals in nearly every fish sample from San Francisco Bay. Researchers found that over 80% of fish from the South Bay contained PFAS exceeding safe consumption levels. The concern is particularly pronounced for local fishing communities that consume significant amounts of these fish, thereby increasing their risk of health issues linked to PFAS, including various cancers and hormone disruptions. The study highlights the origin of these chemicals, primarily from consumer products and urban runoff, indicating an urgent need for assessing and mitigating risks.
In sampling nearly 100 fish between 2009 and 2019, effectively every sample contained PFAS, with concerns being raised for fishing communities consuming fish from the Bay.
The researchers detected elevated levels of PFAS, particularly 7:3 FTCA, not previously found in marine fish, raising alarms about their origin from consumer products.
