WebApr 18, 2011 · Bioaccumulation, bioconcentration, and biosynthesis typically account for the presence of toxic molecules in organisms at low trophic levels, with transfer of compounds from environment to organism via cell membranes in small organisms with high surface-to-volume ratios, and via gill membranes in many larger aquatic species. WebBiomagnification is a process by which contaminant concentrations increase in the tissue of higher species of the food chain. As contaminated smaller organisms are consumed, chemicals are accumulated and magnified in the tissue and organs of larger animals. ...
