Bioaccumulation of Microcystins in Lettuce

Journal of Phycology, 2012
The contamination of lettuce (Lactuca sativa L.) by water‐borne crude extracts of the cyanobacterium microcystin‐producing Microcystis aeruginosa (Kützing) Kützing was investigated. The aim of the study was to determine whether bioaccumulation of microcystins occurs in lettuce foliar tissue when sprayed with solutions containing microcystins at ...

Bioaccumulation of mercury and methylmercury

Water, Air, & Soil Pollution, 1995
The factors controlling the accumulation of mercury in fish are poorly understood. The oil invoked lipid solubility of MMHg is an inadequate explanation because inorganic Hg complexes, which are not bioaccumulated, are as lipid soluble as their MMHg analogs and, unlike other hydrophobic compounds, MMHg in fish resides in protein rather than fat tissue.

Bioaccumulation of marine pollutants

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1979
Abstract Bioaccumulation 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 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

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.
