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 ...

Is p,p-DDE still affecting Baltic Sea cormorants?
, 2007 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

Endocrine disruption effects of p,p′‐DDE on juvenile zebrafish
Journal of Applied Toxicology, 2014AbstractThe persistent organic pollutant p,p′‐DDE, the major metabolite of the insecticide DDT, has displayed evidence of endocrine disruption through the inhibition of androgen binding to androgen receptors in different species. Although p,p′‐DDE was continuously detected in wild fish with abnormal gonad development such as intersex, little is known ...

Environmental Pollution Series A, Ecological and Biological, 1986
Abstract It is generally accepted that p , p ′-DDE causes many species of bird to lay eggs with thinner shells, but the published evidence for this proposition is ambiguous. Data on egg size (measured by maximum length), shape (measured by the ratio of maximum breadth to maximum length), shell thickness (measured indirectly by Ratcliffe's index, I ...

Persistence and binding of p,p'-DDE in soil
Journal of Environmental Science and Health, Part B, 1994Abstract Soil was treated with 14C‐p,p'‐DDE and left under field conditions for 545 days. The dissipation of the chemical was apparently biphasic; halflife of dissipation 271 days. After one year, 61% of the initially applied radiocarbon was lost from soil.

Metabolic effects of p,p′‐DDE on Atlantic salmon hepatocytes
Journal of Applied Toxicology, 2017AbstractDecades after being banned in many countries, DDT and its metabolites are still considered major environmental hazards. The p,p′‐DDE isomer, the DDT metabolite found in highest concentration in aquaculture feeds, is an endocrine disruptor with demonstrated ability to induce epigenetic effects.

Polychlorobiphenyl congeners,p,p?-DDE, and sperm function in humans
Archives of Environmental Contamination and Toxicology, 1986170 seminal samples from fertile men, men with idiopathic oligospermia or azoospermia and men status post vasectomy were analyzed for 74 polychlorobiphenyl (PCB) congeners,p,p′-DDE, mirex, and hexachlorobenzene using the technique of glass capillary gas chromatography with electron capture detection. Low concentrations of 32 PCB congeners were measured

Residues of p,p′-DDE and mercury in lake trout as a function of age
Archives of Environmental Contamination and Toxicology, 1992Lake trout (Salvelinus namaycush) of known age from 1 to 12 years were taken from Cayuga Lake in central New York State in 1991 and p,p'-DDE and mercury were determined in their flesh. The concentrations of p,p'-DDE and mercury increased significantly (p less than 0.001) with increasing age of the fish.

Transplacental and Lactational Transfer of p,p′-DDE in Sprague–Dawley Rats
Toxicology and Applied Pharmacology, 1999p,p'-DDE (hereafter DDE), a persistent metabolite of p,p'-DDT, is a widespread environmental contaminant that can induce antiandrogenic developmental effects in rats. Quantitative measurements of the transfer of DDE from pregnant or lactating dams to the fetus or suckling neonate were performed, and physiologically based pharmacokinetic (PBPK) models ...

Induction of hepatic aromatase by p,p′-DDE in adult male rats
Molecular and Cellular Endocrinology, 20011,1-dichloro-2,2-bis(p-chlorophenyl)ethylene (p,p'-DDE, DDE) is a stable metabolite of the pesticide DDT and a persistent environmental pollutant. Earlier reports have demonstrated that DDE is an endocrine-active compound capable of affecting early-stage sexual differentiation in male rats.
