Bioamplification
|
Natural accumulation of toxins and pesticides that can have amplified negative effects and animal tissues as they move up the food chain. Effect occurs most frequently with fat. Solube pesticides, which are absorbs and stored in fat cells for long periods, rather than being digested and excreted. fat toxins include DDT , mercury and tetrathyl lead
|
|
|
|
Bioaccumulation
|
Organisms higher in food chain have higher concentration of matter than normal. organisms at the top of the food chain accumulate more material then the organisms below them.
