 Definition|title= bioaccumulation
 |definition= Bioaccumulation is the gradual accumulation of a certain chemical into the living tissue of an organism from its environment. This accumulation may result from direct absorption from the environment or from ingestion of food particles.  <ref>http://www.belgochlor.be/nl/B102.htm </ref>}}
 ==Notes==
 The concentration of bioacumulation substances usually increases in with the age of an organism.
 Bioaccumulation is one of the factors used to asses the environmental hazard of a chemical. Chemicals with a higher tendency towards bioaccumulation form a greater hazard.
