biomagnification [ˌbaɪəʊmæɡnɪfɪˈkeɪʃn], bioamplification[ˌbaɪəʊæmplɪfɪˈkeɪʃn], bioaccumulation[ˌbaɪəʊəˌkjuːmjʊˈleɪʃn]名词(the progressive build up of persistent substances by successive trophic levels such as DDT)
While much is generally known about mercury bioaccumulation and biomagnification, the process is extremely complex and involves complicated biogeochemical cycling and ecological interactions.
This biomagnification of toxins is more likely to occur when plastics are small enough to be ingested by low trophic fauna, such as small fish and zooplankton.
Secondary and tertiary consumers accumulate even higher concentrations of these metals by the same logic (for more information on this process, see biomagnification).
