hello friend.... i will say about bioaccumulation and biomagnification with complete examples :

Bioaccumulation is the accumulation of substances, such pesticides, or other chemicals in an organism.

EXAMPLES : An example  of bioaccumulation is the use of DDT as an insecticide in the 1950s and 1960s. 

Biomagnification, which is the increase in concentration of toxins up the food chain, especially affects you.

EXAMPLES : For example spraying a marsh to control mosquitoes will cause trace amounts of DDT to accumulate in the cells of microscopic aquatic organisms, the plankton, in the marsh. In feeding on the plankton, filter-feeders, like clams andsome fish, harvest DDT as well as food.
