Organochlorine Pesticides by LC−MS
Analytical Chemistry, 2008Contamination of water resources by organochlorine pesticides (OCPs) continues to receive widespread attention because of the increasing concern regarding their high persistence and bioaccumulation. These organic pollutants are not amenable by liquid chromatography (LC) coupled to atmospheric pressure ionization-mass spectrometry, which represents the ...

Pesticide Residues: Organochlorines
2014Organochlorinated pesticides, such as dichlorodiphenylethanes, hexachlorocyclohexanes, cyclodienes, hexachlorobenzene, chlordecone, and mirex, are persistent lipophilic compounds that tend to bioaccumulate in food chain. Because of their high vapor pressure, they may be transported long distances by air currents.

Organochlorine pesticides in Argentinian butter
Science of The Total Environment, 1994Organochlorine pesticide residues were analysed in 150 samples of butter collected from several places in the cities of Santa Fe and Rosario (Argentine Republic) over a period of 18 months. Pesticides analysed in butter were: HCH (alpha and gamma isomers), heptachlor and its epoxide, aldrin, dieldrin, and DDT (p,p' DDE, o,p' DDT and p,p' DDT).

Organochlorine Pesticides in Seals and Porpoises
Nature, 1967Seals and porpoises in Scotland and Canada, far from the sites of application of pesticides, can accumulate high concentrations of residues in their blubber. These chemicals are spreading through the long food chain which ends with seals and porpoises and obviously cannot be confined to their place of discharge.

Organochlorine pesticides and human health
Food and Cosmetics Toxicology, 1971Summary In autopsy specimens of body fat from non-occupationally exposed residents of Dade County, Florida, the mean concentrations of DDT-derived material were 9·7 ppm in 42 cases of accidental death, 9·4 ppm in 31 individuals who used pesticides in home or garden only sparingly, 19·4 ppm in 65 moderate users and 27 ppm in 22 individuals who used ...

Accumulation of Organochlorine Pesticides in Man
Journal of Pharmaceutical Sciences, 1972Abstract It is generally known that organochlorine pesticides are slowly eliminated and that they accumulate in humans. By using pharmacokinetic relationships, these properties were quantitated to make them more meaningful. Repeated dosing causes the average level of dichlorodiphenyltrichloroethane at equilibrium to rise to 500 times that following a ...

2019
Indiscriminate use of different pesticides in agriculture has increased over the years, especially in the developing countries. This influences the aquatic environment to a great extent. This also poses a great danger to freshwater organisms, including fish, which constitute a major share in the aquatic environment and contribute to the economy of the ...

Organochlorine Pesticides in Antarctica
Nature, 1967The first reports of organochlorine pesticides in wildlife in the vicinity of the US Antarctic base at McMurdo Sound suggested that local human activity might be responsible. Measurements of samples from the British Antarctic Survey Base at Signy Island in the South Orkneys now suggest that there is a world-wide pattern of distribution by means of the ...

Biodegradation of Organochlorine Pesticides
2015The widespread use of organochlorine pesticides (OCPs), mainly in the past, has caused serious environmental problems. Many OCPs were recently categorized as persistent organic pollutants (POPs) that should be controlled as toxic environmental contaminants.

Persistent organochlorine pesticides in Mexican butter
Food Additives and Contaminants, 2003Organochlorine pesticides have been used in Mexico in malaria control programmes against ectoparasites and as seed dresser. Owing to their chemical stability, they tend to accumulate in the lipid part of the organisms. The stored pesticides are excreted with the endogenous fat during milk production.
