Tag: Polychlorinated biphenyls

Over one billion pounds of polychlorinated biphenyls (PCBs) were produced in the United States before their ban in 1979. What are PCBs in fish and how do these persistent pollutants continue to pose a threat to both marine ecosystems and human health through the consumption of contaminated seafood? These industrial chemicals, once widespread, persist in the environment and accumulate in the fatty tissues of aquatic organisms, creating long-term risks.

Research shows that PCBs have spread across all oceans, with concentrations varying significantly by region. This reality means that tuna, as a top marine predator, can contain levels of polychlorinated biphenyls (PCBs).

Polychlorinated biphenyls (PCBs) are persistent environmental pollutants that accumulate up the food chain, with levels in some fish thousands of times higher than in water. Knowing what fish are low in PCBs is crucial for making healthier seafood choices and reducing your exposure to these concerning chemicals.
