‘Forever Chemicals’ Threaten Community of Bay Fishers
It’s long been risky to eat fish from San Francisco Bay because pollutants like mercury build up in their bodies, and new research shows they are also contaminated with harmful “forever chemicals,” including one never before detected in marine fish. High levels of these chemicals are found in 10 species of fish frequently caught in San Francisco Bay, according to a study that the San Francisco Estuary Institute published in May. The newly detected contamination threatens anglers’ health and what many of them consider a way of life.
Perfluoroalkyl and polyfluoroalkyl substances, or PFAS, are colloquially called “forever chemicals” because they are notoriously difficult to eliminate or break down. PFAS can cause cancers, thyroid and hormone disruption, and developmental delays, and can weaken the immune system, said study author Rebecca Sutton.
