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 ...

Levels of p , p ′-DDE in Liver of Predatory Birds from Calabria, Italy

Bulletin of Environmental Contamination and Toxicology, 2002
In the present study, the levels of OCs in the liver of predatory birds were evaluated. Liver samples were collected from 80 birds (9 different species) found dead or dying in the territory of Calabria region of Southern Italy from 1993 to 1997. Collected data were compared to data already available regarding the OCs contamination in predatory birds ...

Persistent DDT metabolite p,p'–DDE is a potent androgen receptor antagonist

Nature, 1995
The increase in the number of reports of abnormalities in male sex development in wildlife and humans coincided with the introduction of 'oestrogenic' chemicals such as DDT (1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane) into the environment. Although these phenotypic alterations are thought to be mediated by the oestrogen receptor, they are also ...

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 ...

Association between environmental exposure to p, p′-DDE and lindane and semen quality

Environmental Science and Pollution Research, 2014
Scientific concern exists about the toxic effect of dichlorodiphenyldichloroethylene (p, p'-DDE) and lindane on male infertility, and the mechanism underlying male reproductive toxicity of this pesticide remains unanswered. We investigated not only the possible association between the chlorinated pesticide levels and semen quality in nonoccupationally ...

Influence of plant–earthworm interactions on SOM chemistry and p,p′-DDE bioaccumulation

Chemosphere, 2011
Laboratory experiments assessed how bioaccumulation of weathered p,p'-DDE from soil and humic acid (HA) chemistry are affected by interactions between the plants Cucurbita pepo ssp. pepo and ssp. ovifera and the earthworms Eisenia fetida, Lumbricus terrestris, and Apporectodea caliginosa. Total organochlorine phytoextraction by ssp.

Effect of mycorrhizal fungi on the phytoextraction of weathered p,p-DDE by Cucurbita pepo

Journal of Hazardous Materials, 2006
Field experiments were conducted to assess the impact of inoculation with mycorrhizal fungi on the accumulation of weathered p,p'-DDE from soil by three cultivars of zucchini (Cucurbita pepo spp. pepo cv Costata Romanesco, Goldrush, Raven). Three commercially available mycorrhizal products (BioVam, Myco-Vam, INVAM) were inoculated into the root system ...

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 ...
