Bioaccumulation of nickel by algae

Environmental Science & Technology, 1984
Six strains of algae and one Euglena sp. were tested for their ability to bioaccumulate nickel. Radioactive /sup 63/Ni was used together with a microplate technique to determine the conditions for nickel removal by axenic cultures of cyanobacteria, green algae, and one euglenoid.

Plutonium bioaccumulation in seabirds

Journal of Environmental Radioactivity, 2011
The 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.

Bioaccumulation processes in ecosystems

Experientia, 1992
The 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 ...

Assessing bioaccumulation with biomagnification factors from dietary bioaccumulation tests

Integrated Environmental Assessment and Management
Abstract Despite the fact that the UN Stockholm Convention on persistent organic pollutants specifically acknowledges that Arctic ecosystems and Indigenous communities are particularly at risk due to biomagnification of contaminants in traditional foods, the bioconcentration factor (BCF) of substances in fish remains the preferred metric

Classification of bioaccumulative and non-bioaccumulative chemicals using statistical learning approaches

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 of contaminants in fish

1998
The term bioaccumulation is defined as uptake, storage, and accumulation of organic and inorganic contaminants by organisms from their environment. Bioaccumulation therefore results from complex interactions between various routes of uptake, excretion, passive release, and metabolization.

Bioaccumulation and Biomagnification

2015
When 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 of Arsenicals

1975
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 ...
