Organochlorine compounds and estrogen-related cancers in women

Cancer Causes and Control, 1995
The organochlorines, a diverse group of some 15,000 compounds, have been implicated increasingly as being harmful to humans. Some congeners of DDT and PCB elicit very weak estrogenic responses in animals, while the dioxin TCDD and related compounds have antiestrogenic properties.

Storage of some organochlorine compounds in toxemia of pregnancy

Environmental Research, 1980
Abstract Nine out of 18 cases of toxemia of pregnancy had high PCB serum levels in comparison with a control group of 12 women with normal pregnancies. Seven out of the nine high PCB levels cases were multiparae. These findings suggest a role of PCBs in the promotion of toxemia of pregnancy, possibly by depressing the maternal immunological response ...

Organochlorine compounds in mother and fetus during labor

Environmental Research, 1977
Abstract Some features of the storage of organochlorine compounds in mother and fetus as assessed during labor are reported in this paper. Organochlorine insecticides (DDT and metabolites, dieldrin, y-BHC, and heptachlor expoxide) and polychlorinated biphenyls were assessed in maternal adipose tissue, maternal blood, fetal blood, maternal uterine ...

Reconstruction of organochlorine compound inputs in the Tagus Prodelta

Science of The Total Environment, 2016
Twenty century time-resolved variability of riverine deposits of polychlorobiphenyls (PCBs), DDTs, hexachlorocyclohexanes (HCHs) and hexachlorobenzene (HCB) was studied in three (210)Pb dated sediment cores collected in a depositional shelf area adjacent to the Tagus estuary (the Tagus Prodelta).

Is There a Correlation Between Organochlorine Compounds and Undescended Testes?

European Journal of Pediatric Surgery, 2000
Some pesticides and synthetic chemicals are known to act as hormonal modulators, often possessing oestrogenic activity (xenooestrogens). They are persistent and accumulate in fatty tissue. Aim of our study is to address the question, whether a selection of such compounds is to be found in the fatty tissue of children undergoing surgical procedures and ...

Catalytic dechlorination of organochlorine compounds III. Lindane

Bulletin of Environmental Contamination and Toxicology, 1977
We found that in-situ preparation of Ni2B with the addition of excess NaBHa was--6ff--ective in the extensive dechlorination of DDT (DENNIS-and COOPER, 1975), heptachlor and chlordane (DENNIS and COOPER, in press). Similar systems have been used to reductively dehalogenate aromatic systems (EGLI, 1968) and as a site specific method for deuteration ...

Organochlorine Compounds in Norwegian Human Fat and Milk

Acta Pharmacologica et Toxicologica, 1978
Abstract Analyses were carried out in 1975/76 of 58 samples of human, perirenal fatty tissue and 45 samples of human milk with regard to persistent organochlorine compounds. A corresponding investigation was carried out in 1969/70. A comparison of the results suggests that a decrease in the content of DDT and its metabolites occurs.

[Organochlorine compounds in human milk].

Zentralblatt fur Hygiene und Umweltmedizin = International journal of hygiene and environmental medicine, 1991
The impact of life style characteristics and chemical exposure conditions of about 80 nursing women on the contents of Organochlorine compounds (OCC) in their breast milk is analyzed and described by a robust statistical procedure. Information on independent variables such as age, diet, smoking, occupation and chemical exposures is obtained by a ...

ORGANOCHLORINE COMPOUNDS IN PINE NEEDLES: METHODS AND TRENDS

Environmental Toxicology and Chemistry, 1994
Abstract During April 1989, needles from Scotch pine (Pinus sylvestris) trees were collected from a network of stations in West Germany, Denmark, Norway, and Sweden. Samples from selected stations were analyzed for hexachlorobenzene (HCB), pen-tachlorophenol (PCP), hexachlorocyclohexane isomers (α-HCH and γ-HCH [lindane]), DDT, and DDE ...

DETERMINATION OF ORGANOCHLORINE COMPOUNDS IN NEUSTON FROM THE MEDITERRANEAN

Environmental Technology, 2008
A reliable analytical procedure was developed to determine trace levels of organochlorine compounds in neuston samples. Freeze-dried samples were extracted by sonication (3 x 15 ml cyclohexane, 15 min) followed by gel permeation chromatography (GPC) and gas chromatography electron capture detection (GC-ECD) determination.
