Business / Agriculture / Bioaccumulation: The absorption and concentration of toxic chemicals, heavy metals, and certain pesticides in plants and animals. Toxicity can be expressed in several ways: lead that is ingested by calves can bioaccumulate in their bones, interfering with calcium absorption and bone development: stored chemicals may be released to the blood stream at a later time, for example, during gestation or weight loss: and chemicals may concentrate to lethal levels at upper ends of the food chain. Bioconcentration is a synonym for biaccumulation.
