Bioaccumulation processes in ecosystems
Experientia, 1992The fate of environmental pollutants--the various isotopes of elements, and inorganic or organic compounds--is a fundamental aspect of ecology and ecotoxicology, and bioaccumulation is a phenomenon often discussed in this context. Human activities have drastically altered natural concentrations of many substances in the environment and added numerous ...

Bioaccumulation of marine pollutants
Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1979Bioaccumulation of pollutants can occur from sea water, from suspended particles, from sediments and through food chains. The rate at which accumulation occurs in an organism depends not only on the availability of the pollutant but also on a whole range of biological, chemical and environmental factors.

Bioaccumulation and Biomagnification
2015When a toxic chemical is taken up into an organism, it may be excreted, stored, or metabolized. What happens to the chemical will determine what its effects will be on that organism, and potentially the predators that may eat it.

Bioaccumulation and Biomonitoring
2016Bioaccumulation is defined as the increase of contaminant concentrations in aquatic organisms following uptake from the ambient environmental medium. Different sources of exposure contribute to contaminant bioaccumulation. Toxicokinetic parameters are critical in the bioaccumulation processes, including the dissolved uptake rate constant, dietary ...

Bioaccumulation/Storage/Detoxification
2013Bioavailability refers to the fraction of the total chemical in the environment that is available for absorption into biota. This depends on the chemical, the organism, and environmental conditions, such as temperature, DO, and pH. Uptake of contaminants generally is via the skin, respiratory system, or food, with food being a major route of uptake for

Arsenic is bioconcentrated by aquatic organisms but not biomagnified. Plants usually accumulate more arsenic than fish, and crustacea accumulate intermediate amounts. Marine organisms normally contain more arsenic than their fresh water counterparts. However, the arsenic contained in the organisms is apparently not toxic to animals or humans, and is ...
