Organochlorine pesticide residues in human breast tissue and their relationships with clinical and pathological characteristics of breast cancer

Environmental Toxicology, 2018
Agricultural pesticides are abundant environmental contaminants worldwide, prompting interest in studying their possible detrimental health effects. We examined organochlorine residues by quadrant (n = 245) in breast adipose tissues from 51 women with ...

Pesticide Residues: Organochlorines

2014
Organochlorinated 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, 1994
Organochlorine 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, 1967
Seals 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, 1971
Summary 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 ...

Organochlorine Pesticides in Antarctica

Nature, 1967
The 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

2015
The 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, 1972
Abstract 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 ...
