Biological Magnification. From: Treatise on Geochemistry, 2007. This is biomagnification, and it means that higher-level predators-fish, birds, and marine mammals-build up greater and more dangerous amounts of toxic materials than animals lower on the food chain. Biomagnification is the process by which toxic chemicals build up within predators. The concentration effect occurs because DDT is metabolized and excreted much more slowly than the nutrients that are passed from one trophic level to the next.
