网页Bioaccumulation is defined as the ‘net result of uptake, transformation and elimination of a substance in an organism due to all routes of exposure (i.e., air, water, sediment/soil, and food)’ and degradation as ‘the decomposition of organic molecules to smaller molecules and eventually to carbon dioxide, water, and salts.’
Bioaccumulation, bioconcentration, biomagnification
网页Bioaccumulation is the intake of a chemical and its concentration in the organism by all possible means, including contact, respiration and ingestion. Biomagnification occurs when the chemical is passed up the food chain to higher trophic levels, such that in predators it exceeds the concentration to be expected where equilibrium prevails ...
