Chlorinated biphenyls and p,p'-DDE in Mediterranean surface waters
Croatica Chemica Acta, 1997 Individual chlorobiphenyls (CBs) and p,p'-DDE were determined in solution and suspension in surface transects of the open Mediterranean Sea in 1987. Large volumes of sea water (1400—1700 dm3) were analyzed. Concentrations of CBs were low in solution (

p,p′-DDE fails to reduce the competitive reproductive fitness in Nigerian male guppies
Ecotoxicology and Environmental Safety, 2006 The ecologically highly important effect of intermale competition is assessed here in a new approach to evaluating endocrine disruption at the population level. A guppy (Poecilia reticulata) male exposed to the antiandrogenic DDT metabolite p,p'-DDE competed against an unexposed male for the opportunity to fertilize a female.

Gene expression analysis of largemouth bass exposed to estradiol, nonylphenol, and p,p′-DDE
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2002 The purpose of this study was to determine the specific expression profile of 132 genes, some of which are estrogen responsive, in largemouth bass (LMB) following exposure to estradiol (E(2)), or to two hormonally active agents, 4-nonylphenol (4-NP) and 1,1-dichloro-2, 2-bis (p-chlorophenyl) ethylene (p,p'-DDE), using gene array technology. The results
