Recent studies show that individuals eat more sport caught fish than was previously assumed. Therefore, a more stringent advisory was needed in order to protect human health and allow individuals to make informed decisions on the types and amounts of fish they eat. Assume that the fish are in a Group 2 advisory. Follow the cooking instructions on page 57.
Contaminants found in Indiana fish include PCBs, pesticides, and heavy metals.
Two of these contaminants, mercury and PCBs, are the major contaminants found in Indiana fish. PCBs are synthetic oils once widely used in electrical transformers and capacitors. PCBs break down very slowly in the environment. Mercury is a naturally-occurring metal which does not break down, but recycles between land, water, and air. Some mercury that reaches Indiana waters occurs naturally.
