Adipose tissue concentrations of p,p′-DDE and the risk for endometrial cancer

Gynecologic Oncology, 2004
To evaluate in a case-control study possible risk of endometrial cancer associated with environmental endocrine disruptors.We analyzed the adipose tissue concentrations of polychlorinated biphenyls, hexachlorobenzene (HCB), p,p'-dichlorodiphenyl-dichloroethylene (p,p'-DDE), chlordanes, and polybrominated biphenyls in 76 cases with endometrial cancer ...

Concentrations of p,p′-DDE in plasma of nestling Wood Storks from Georgia

Chemosphere, 2007
We determined the concentrations of organochlorine pesticides and total PCBs in plasma of nestling Wood Storks (Mycteria americana) from two colonies in Georgia in 2000. Of 20 compounds analyzed for, only p,p'-DDE was quantified in reportable concentrations, ranging from

In vitro exposure to the organochlorine p,p′-DDE affects functional human sperm parameters

Chemosphere, 2015
Although no information exists regarding the levels of p,p'-dichlorodiphenyldichloroethylene (p,p'-DDE) on reproductive fluids of heavily exposed populations, they are possibly quite high given the serum levels reported so far. In these populations altered semen quality has been reported, although the direct effects of this DDT metabolite on crucial ...

Structure of phenolic metabolites of p,p′-DDE in rat, wild seal and guillemot

Nature, 1975
WE recently described the isolation and characterisation of metabolites of polychlorinated biphenyls from field-collected samples, that is faeces from guillemots and seals1. In addition to the PCB metabolites—hydroxychlorobiphenyls—we unexpectedly found two compounds which after treatment with diazomethane gave mass spectra consistent with p,p′-DDE (1 ...

Is p,p-DDE still affecting Baltic Sea cormorants?

No abstracts are to be cited without prior reference to the author.During a cormorant (Phalacrocorax carbo sinensis) population control campaign in May 2005, eggs were collected from a ground-breeding colony on the small island Heuwiese (N 54°25’, E 13°7’) at the Baltic Sea shore of Western Pomerania, Germany. The hatching status of all eggs was scaled

Nonoccupational Determinants of Plasma DDT and p,p'-DDE in Men from Chiapas, Mexico

Archives of Environmental Health: An International Journal, 2004
A cross-sectional study was conducted to evaluate nonoccupational biological exposure to 1,1,1-trichloro-2,2-bis(4-chlorophenyl)ethane (DDT) compounds and to identify the main factors associated with such exposure in a malaria endemic region in Mexico.

p,p′-DDE induces testicular apoptosis in prepubertal rats via the Fas/FasL pathway

Toxicology Letters, 2010
1,1-Dichloro-2,2 bis(p-chlorophenyl) ethylene (p,p'-DDE), the major metabolite of 2,2-bis(4-chlorophenyl)-1,1,1-trichloroethane (DDT), is a known persistent organic pollutant and male reproductive toxicant. It has antiandrogenic effect. However, the mechanism by which p,p'-DDE exposure causes male reproductive toxicity remains unknown. To elucidate the

Circulating levels of p,p'-DDE are related to prevalent hypertension in the elderly

Environmental Research, 2014
Polychlorinated biphenyls (PCBs) and dioxin given to experimental animals increase the blood pressure. We therefore investigated if circulating levels of persistent organic pollutants (POPs) were related to hypertension in a population-based sample of men and women.One thousand and sixteen subjects aged 70 years were investigated in the Prospective ...

Polychlorinated biphenyls and p, p′-DDE in Loggerhead and Green postyearling Atlantic sea turtles

Bulletin of Environmental Contamination and Toxicology, 1983
The Green (Chelonia mydas) and Loggerhead (Caretta caretta) sea turtles are classified as endangered and threatened species respectively (CLARK & KRYNITSKY 1980). ' The Green sea turtle has a distribution in the Atlantic which ranges from New England to Mardel Plata and Necochea Argentina and from the English Channel to South Africa (HIRTH 1971 ...

p,p′-DDE bioaccumulation in female sea lions of the California Channel Islands

Continental Shelf Research, 2002
Abstract An area of sediment on the Palos Verdes shelf and in Santa Monica Bay off Los Angeles, CA is contaminated with DDE and other breakdown products of DDT as a result of discharges of DDT through the Whites Point outfall. Elevated concentrations of DDE have been found in the water column of the Palos Verdes Shelf and in various fish species ...
