(Askeri) bioaccumulation

The accumulation of a substance, such as a toxic chemical, in various tissues of a living organism: the bioaccumulation of mercury in fish

- The tendency for substances to increase in concentration in living organisms as they take in contaminated air, water, or food because the substances are very slowly metabolized or excreted

The uptake and retention of environmental substances by an organism by means other than the ingestion of food See Biomagnification

Related Topics: [wetlands] Although organisms are able to moderate the concentrations of most substances within their bodies, some substances cannot be regulated and consequently tend to become more concentrated in living tissues as they move through the food chain Consequently if toxins capable of bioaccumulating are present in a system, the organisms at the top of the food chain are likely to suffer the most Probably the most famous and best documented of all bioaccumulants is DDT

n: An increase in the concentration of a chemical in specific organs or tissues at a level higher than would normally be expected

the process by which chemicals are amassed by organisms from water directly or through the consumption of food containing the chemicals

(bioaccumulation) A process by which chemical substances are ingested and retained by organisms, either from the environment directly or through consumption of food containing the substances

The process where chemical substances from water or food build up in an organism

The process whereby certain toxic substances collect in living tissues, thus posing a substantial hazard to human health or the environment

The accumulation of a particular element or compound by any or all members of a particular biota

The net accumulation of a chemical by an organism as a result of uptake from all routes of exposure (Suter 1993)

The uptake and retention of chemicals by biota, from the water, sediment, and food

The accumulation by organisms of contaminants through ingestion or contact with skin or respiratory tissue The net accumulation of a substance by an organism as a result of uptake from all environmental sources As an organism ages, it can accumulate more of these substances, either from its food or directly from the environment Bioaccumulation of a toxic substance has the potential to cause harm to organisms, particularly to those at the top of the food chain

{i} accumulation of material that is toxic, accumulation of a harmful substance; accumulation of foreign substances in the body

The process by which certain metals and chemical levels in the tissue of organisms increase with higher standing in the food chain

The retention and concentration of a substance by an organism

Intracellular accumulation of environmental pollutants such as organic materials by living organisms Accumulation of a chemical substance in living tissue

General term describing a process by which chemicals are taken up by a plant or animal either directly from exposure to a contaminated medium (soil, sediment, water) or by eating food containing the chemical Related terms are bioconcentration in which chemicals are absorbed by an animal or plant to levels higher than the surrounding environment; and biomagnification, in which chemical levels in plants or animals increase from transfer through the food web (e g , predators have greater concentrations of a particular chemical than their prey)

Intracellular accumulation of environmental pollutants, such as heavy metals, by living organisms

Bioaccumulation is a process by which substances build up over time in the tissues of living organisms When POPs are ingested, for example, it is often difficult for an organism to break them down or to excrete them Therefore, the POPs accumulate in the tissues of the organism and build up over time
