The concentration of a particular substance in a living organism, possibly with harmful effects. The likelihood of this occurring is expressed as the bioaccumulation potential and can be estimated by [..]

The idea that substances collect in an animal’s system and although they may remain immune to their effects there are other species that can be negatively affected by its presence in their environment [..]

process by which chemicals are absorbed by an organism, either from exposure to a substance with the chemical or by consumption of food containing the chemical.

Increasingly concentrated accumulation of substances, especially pollutants, at successively higher trophic levels in food chains. bioassay

is a general term for the accumulation of substances, such as pesticides (DDT is an example), methylmercury, or other organic chemicals in an organism or part of an organism. The accumulation process involves the biological sequestering of substances that enter the organism through respiration, food intake, epidermal (skin) contact with the substan [..]

The presence of a chemical substance in higher concentrations in an organism than in the direct environment or in its food.

The process that leads to accumulation of pollutants over time in the fatty tissue, or lipids, of living things. The primary chemicals that tend to bioaccumulate are persistent organic pollutants because they dissolved easily in fatty tissues and are not easily metabolized in the body.

The accumulation of a substance within the tissues of an organism, which can lead to biomagnification through the food web

the accumulation and concentration of stable substances as they move up the food chain. Perhaps the best known examples are organochlorine pesticides such as DDT, now banned in New Zealand

The process by which the amount of a substance in a living organism (or its parts) increases with time (WHO, 1979).

Bioaccumulation denotes the accumulation of a substance in a living organism as a result of its intake both in the food and also from the environment. Determination of the B-factor (Bioaccumulation Fa [..]

The process by which  the concentrations of some toxic chemicals gradually increase in living tissue,  such as in plants, fish, or people as they breathe contaminated air, drink contaminated water, or eat contaminated food.

The process by which a contaminant accumulates in the tissues of an individual organism. For example, certain chemicals in food eaten by a fish tend to accumulate in its liver and other tissues.

The retention and concentration of a substance by an organism.

Bioaccumulation is an increase in concentration of a toxic substance in organs and tissues in excess of what is normally expected. The toxic substance is bioconcentrated if its concentration in organs and tissues exceeds those of the surrounding air or water. These accumulations can harm the animal or be passed on to a predator.

The process by which toxic chemicals can accumulate in animal tissues and become concentrated when they move up the food chain.

The uptake and storage of chemical contaminants by living animals and plants. This can occur through direct contact with contaminated water or sediment or through the ingestion of another organism tha [..]

The process by which organisms absorb chemicals or elements  directly from their environment.  Often refers to residues of chemical compounds  applied to waters for a control purpose being retained in substrates and  being absorbed by resident micro-organisms to form a "toxic soup".

Bioaccumulation refers to the accumulation of substances such as chemicals or toxic substances in an organism that occurs when its absorption rate is greater than the rate at which the substance is lost. It can lead to chronic poisoning even if environmental levels of the toxin are not very high. In fish, bioaccumulation can be predicted by models. [..]

Higher concentration of a chemical in cells than in the nonliving surroundings.

the uptake of a substance (usually toxic substance) from the environment and from food, that is stored long-term (accumulates) in the tissues of living organisms. Read more on hazardous substances.

uptake and retention of substances by an organism from its surrounding medium (usually water) and from food.

The accumulation of a chemical in tissues of an organism to levels greater than in the surrounding medium. Accumulation may take place by breathing, swallowing or dermal contact.

The process by which a contaminant accumulates in the tissues of an individual organism. For example, certain chemicals in food eaten by a fish tend to accumulate in its liver and other tissues.

Progressive increase in the amount of a substance in an organism or part of an organism which occurs because the rate of intake exceeds the organism's ability to remove the substance from the bod [..]

Bioaccumulation is the process by which chemicals concentrate in an organism. For example, DDT concentrates in fish and birds that eat fish. This concentration effect is expressed as the ratio of the [..]

Substances that are stored in living tissues (including people), and remain for very long periods of time, during which concentrations can reach very high levels. These substances can also be transfer [..]

The uptake and retention of a bioavailable chemical from any one of or all possible external sources (water, food, substrate, air).

the accumulation of a substance, such as a toxic chemical, in the tissues of a living organism.

accumulation of fat-soluble and stable pollutants in fat tissues in animals, typically fat, liver and brain in man, egg yolk in birds, and mothers milk

The process by which the concentrations of some toxic chemicals gradually increase in living tissue, such as in plants, fish, or people as they breathe contaminated air, drink contaminated water, or e [..]

The occurrence of chemicals in much higher concentrations in organisms than in the ambient environment. Compare with food-web magnification.
