1990
In many parts of the world, the changing weather patterns of the 1980s certainly focussed attention much more on the importance of fresh water. In times of drought, not only were lakes and rivers shallower than normal but reservoirs were lower, crops were poorer, gardens were drier and cars were dirtier as a result. Yet elsewhere, or at another time of

Persistence of fenthion in the aquatic environment
Bulletin of Environmental Contamination and Toxicology, 1989We have investigated the effect of some potential chemical, photochemical, biological and environmental conditions upon the degradation of fenthion in laboratory and field experiments. These experiments have been designed with an emphasis on possible environmental situations into which fenthion might be introduced.

Organochlorine compounds in aquatic environments
Archives of Environmental Contamination and Toxicology, 1980The body burdens of five organochlorine compounds were determined in several marine fishes and invertebrates from two localities in Norway. DDE, PCBs, and pentachlorobenzene showed uniform levels, especially on a fat weight basis, while hexachlorobenzene and octachlorostyrene were detected at various levels in the different species.

Toxaphene in the aquatic environment of Greenland
Environmental Pollution, 2015The octa- and nonachlorinated bornanes (toxaphene) CHBs 26, 40, 41, 44, 50 and 62 were analysed in Arctic char (Salvelinus alpinus), shorthorn sculpin (Myoxocephalus scorpius), ringed seal (Pusa hispida) and black guillemot eggs (Cepphus grylle) from Greenland.

Occurrence of antibiotics in the aquatic environment
Science of The Total Environment, 1999The recent monitoring of drug residues in the aquatic environment has gained much interest as many pharmaceutical compounds can frequently be found in sewage treatment plant (STP) effluents and river water at concentrations up to several microgram/l.

Photochemistry of iron in aquatic environments
Environmental Science: Processes & Impacts, 2020Light-induced reduction of Fe(iii) delivers Fe(ii) as nutrient or substrate for growth of planktonic or sedimentary organisms. Biological uptake, as well as chemical or microbial oxidation of Fe(ii) close this photochemically driven iron cycle.

Methylation of Selenium in the Aquatic Environment
Science, 1976Conversion of inorganic and organic selenium compounds to volatile selenium compounds (dimethyl selenide, dimethyl diselenide, and an unknown compound) by microorganisms in lake sediment has been observed. This conversion could also be effected by pure cultures of bacteria and fungi.

Speciation of Iron in the Aquatic Environment
Water Environment Research, 2014ABSTRACT: Iron is one of the basic metals occurring in the aquatic environment and it is considered a macroelement with regard to live organisms. This metal has a broad range of applications that, together with factors conditioning its chemical transitions, results in the occurrence of many iron species in water. Depending on water and land development
