Bioaccumulation is an ecological term used to describe the accumulation of certain substances in the tissues of living organisms. There are several synonyms that can be used to describe this phenomenon, including biomagnification, biological concentration, and bioconcentration. Biomagnification refers to the process by which the concentration of a particular substance becomes increasingly higher as it moves up the food chain. Biological concentration is a term used to describe the overall level of a particular substance in an organism's tissues or organs. Bioconcentration is similar to biomagnification but typically refers to the accumulation of a substance in a single organism rather than the entire food chain.
