We studied pregnancy-related changes in serum concentrations of five polychlorinated
biphenyls (PCBs, CB 118, CB 138, CB 153, CB 156, CB 180), three hydroxylated PCB …

In animal studies, exposure to persistent organochlorine pollutants (POPs) in utero and
through mother's milk has been suggested to affect the onset of puberty. However, human …

Organochlorine pesticides and polychlorinated biphenyls (PCBs) are consistently found in
human tissues. Serum levels of organochlorine compounds (OC) in pregnant women in …

Objectives: There is a concern that persistent organohalogen toxicants, such as
polychlorinated biphenyls (PCBs), might display endocrine-disrupting effects in exposed …

Abstract Background Persistent organic pollutants (POPs), including polychlorinated
biphenyls (PCBs) and pesticides bioaccumulate through the food chain and cross the …

Recent declines in the secondary sex ratio (SSR), defined as the ratio of males to females at
birth, in some industrialized countries may be attributed to exposure to environmental …

Female infertility rates have increased by approximately 4% since the 1980s. There is
evidence of adverse effects on female fertility in relation to exposure of chemical pollution in …

Background We performed a cross-sectional study of associations between personal
characteristics and lipid-adjusted serum concentrations of certain PCB congeners and …

Organochlorine compounds and their metabolites bioaccumulate and have been detected in
follicular and genital tract fluids of humans and animals. This study was designed to …

Although some persistent organic pollutants (POPs) may not be currently in production,
many of these chemicals still exist ubiquitously in the environment and continue to represent …
