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 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.

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 ...

Persistent organochlorinated pesticides and mechanisms of their toxicity
Toxicology, 2013Persistent organic pollutants comprised of organic chemicals like polychlorinated biphenyls, dibenzo-p-dioxins, dibenzofurans and organochlorinated pesticides which have many characteristics in common. Once released in the environment they resist physical, biological, chemical and photochemical breakdown processes and thus persist in the environment ...

Organochlorine pesticide residues in bamboo shoot
Journal of the Science of Food and Agriculture, 2010Xenobiotic organochlorine pesticides (OCPs) are a major environmental problem because of their historic widespread use, pronounced persistence against chemical and biological degradation, and bioaccumulation in the food chain. Pesticide use is prevalent in the production of edible bamboo shoots, which are exported widely from China.

Concentration of organochlorine pesticides in wine corks
Chemosphere, 2001Wine corks were extracted and analyzed for 23 organochlorine pesticides, including alpha-, beta-, and gamma-hexachlorocyclohexanes (HCH), hexachlorobenzene, DDT, DDE and DDD, chlordane, endosulfan, dieldrin, aldrin, and endrin. This was done to investigate the occurrence, concentrations, composition profiles, and possible sources of organochlorine ...

Organochlorine pesticide residues in Songkla Lake
Environmental Monitoring and Assessment, 1994The water quality of Songkla Lake for organochlorine (OC) pesticide contamination was studied from chosen sampling sites (stations) using the lakes geographic data and pollution sources. The water samples were collected monthly from 13 stations in Songkla Lake during September 1991-November 1992.
