Organochlorine compounds in human brain

Human & Experimental Toxicology, 1996
Having observed polychlorinated biphenyls (PCBs) in brain tissue obtained post mortem from two men we have carried out a study of organochlorine compounds in frontal cortex from patients with Parkinson's disease (PD) and from controls. No PCBs were found in any of those samples.

Organochlorine compounds in aquatic environments

Archives of Environmental Contamination and Toxicology, 1980
The 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.

Persistent Organochlorine Compounds and Birth Weight

Annals of Epidemiology, 2003
To determine whether weight at birth is related to prenatal exposure to persistent organochlorine compounds.Birth weight was obtained for 197 singleton infants drawn from the general population born in two cities in Ukraine in 1993 to 1994.

Organochlorinated compounds in Caspian Sea sediments

Marine Pollution Bulletin, 2004
Several organochlorinated contaminants, including numerous pesticides, were determined in coastal sediments from the Caspian Sea. The most important contaminants were p,p'-DDT (up to 7400 pg g(-1)) and its breakdown products, p,p'-DDD (up to 3400 pg g(-1)) and p,p'-DDE (up to 1300 pg g(-1)). Although the contamination was most severe in Azerbaijan, the

Global Distribution of Persistent Organochlorine Compounds

Science, 1995
The global distribution of 22 potentially harmful organochlorine compounds was investigated in more than 200 tree bark samples from 90 sites worldwide. High concentrations of organochlorines were found not only in some developing countries but also in industrialized countries, which continue to be highly contaminated even though the use of many of ...

Organochlorine Compounds in Pine Needles from Croatia

Bulletin of Environmental Contamination and Toxicology, 2012
Levels of seven organochlorine pesticides and 17 congeners of polychlorinated biphenyls (PCBs) were analysed in pine needles collected at eight sites along eastern Adriatic coast (Croatia). The concentration of organochlorine pesticides and PCBs ranged between 0 (below determination limit) and 7.44 ng g(-1) in 1-year-old needles and between 0 (below ...

Premature delivery and organochlorine compounds: Polychlorinated biphenyls and some organochlorine insecticides

Environmental Research, 1982
Abstract Some organochlorine compounds (OCC), DDT and metabolites, γ-HCH, dieldrin, heptachlor epoxide and polychlorinated biphenyls were assessed in the serum of 17 women with premature delivery (PD) and 10 women with normal, third-trimester pregnancy.

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 ...

Bioaccumulation of organochlorine compounds in earthworms

Soil Biology and Biochemistry, 1992
Abstract Bioaccumulation of chlorophenolic wood preservatives 2,3,4,6-tetrachlorophenol (2346-TeCP) and pentachlorophenol (PeCP) and their metabolites in earthworms were studied in the laboratory, and by taking worm samples from the contaminated soil of a sawmill which was abandoned 28 yr ago.

Organochlorine Compounds and Xenoestrogens in Human Endometrium

1998
Numerous in vitro-studies have demonstrated weak estrogenic effects of a large number of environmental chemicals (Jobling et al., 1995; Soto et al., 1994; Colborn and Clement, 1992). A major limitation of in vitro-testing is that it does not account for pharmacokinetic properties of the test compounds. Many xenoestrogens contain hydroxy groups or ester
