WebSep 5, 2024 · Bioaccumulation Bioaccumulation is the buildup of chemicals in an organism’s tissues over its lifetime. While bioaccumulated toxins are commonly fat soluble, such as DDT and PCBs, water-soluble toxins, such as inorganic forms of heavy metals can also bioaccumulate. WebSome persistent chemicals such as DDT and PCB bioaccumulate in the organism and become concentrated at levels which are much higher in living cells than in water. Bioaccumulate is repeated at each step of the food chain. The process of increasing concentrated through the food chain is called biomagnification
