Plutonium bioaccumulation in seabirds
Journal of Environmental Radioactivity, 2011The aim of the paper was plutonium (²³⁸Pu and ²³⁹⁺²⁴⁰Pu) determination in seabirds, permanently or temporarily living in northern Poland at the Baltic Sea coast. Together 11 marine birds species were examined: 3 species permanently residing in the southern Baltic, 4 species of wintering birds and 3 species of migrating birds.

Molecular Diversity, 2008
The present work aimed at developing in silico models allowing for a reliable prediction of bioaccumulative compounds and non-bioaccumulative compounds based on the definition of Bioconcentration Factor (BCF) using a diverse data set of 238 organic molecules.

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 gadolinium in freshwater bivalves
Environmental Science and Pollution Research, 2017In this study, the presence of anthropogenic gadolinium (Gd) was evaluated in rivers, close to wastewater treatment plant outputs. Then, one site was selected for in situ experiments to assess the bioaccumulation of Gd in the digestive gland and in the gills of two bivalves (Dreissena rostriformis bugensis and Corbicula fluminea).

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 Trophic Transfer [PDF]
, 2011 Sediments are not simply a passive sink for contaminants, on the contrary, benthic animals can both act as accumulators with subsequent transfer of materials to their predators, and through their physiological processes can transport contaminants either in solution or adsorbed to sediment particles. Worms can accumulate metals and have metabolic routes

Bioaccumulation of radiocaesium in Arctic seals
Marine Pollution Bulletin, 2002Seals are high trophic level feeders that bioaccumulate many contaminants to a greater degree than most lower trophic level organisms. Their trophic status in the marine food web and wide-spread distribution make seals useful sentinels of arctic environmental change.

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 ...

Bioaccumulation of cadmium in marine organisms
Experientia, 1984It has been established that, although Cd occurs in the marine environment in only trace concentrations, most marine organisms, especially molluscs and crustaceans, can accumulate it rapidly. Cadmium is not uniformly distributed in the body and selectively accumulates in specific organs like liver, kidney, gills, and exoskeleton.
