Biomagnification, also known as bioamplification or biological magnification, occurs when the concentration of a substance, such as DDT or mercury, in an organism exceeds the background concentration of the substance in its diet. This increase can occur as a result of: The following is an example showing how bio-magnification takes place in nature...

ecological magnification Sequence of processes in an ecosystem by which higher
concentrations are attained in organisms at higher trophic levels (at higher levels in the food web); at its simplest, a process leading to a higher concentration of a su...

The accumulation of a substance by an animal that preys on other animals that have themselves accumulated the substance. This process can deliver remarkably high concentrations of persistent chemicals or
heavy metals to top predators even if the levels in the ...

This is a general term applied to the sequence of processes in an ecosystem by which higher concentrations are attained in organisms of higher trophic level, i.e., of higher levels in the food chain. The process by which xenobiotics increase in body concentration in organisms through a series of prey-predator relationships from primary producers to…

bioamplification, biomagnification The increase in concentration of a pollutant from one trophic level in a food chain to another; this usually occurs when the pollutant is metabolized and excreted much more slowly than the nutrients that are passed from one trophic level to the next. Such pollutants are long-lived, mobile, soluble in fats, and bi...

This term denotes the accumulation of substances in a living organism from food intake. Simple organisms such as algae can absorb minute quantities of a substance which are transferred through the food chain to higher levels such as fish and preditory birds. Biomagnification along a food chain will result in the highest concentrations of a substanc...

The process by which some substances increase in concentration in a food chain or food web. Biomagnification occurs because certain substances, including some pesticides and heavy metals, are not easily degraded and can accumulate in organisms’ tissues or internal organs. Pregnant women are advised not to eat certain kinds of fish because of the ...
