The accumulation of a chemical in tissues of a fish or other organism to levels greater than in the surrounding medium.

The accumulation of a chemical in tissues of an organism (such as fish) to levels that are greater than the level in the medium (such as water) in which the organism resides.

The accumulation of a chemical in the tissues of an organism as a result of direct exposure to the surrounding medium (e.g. water; i.e. it does not include food web transfer).
