(2002) have shown that Flemish adolescents exposed to polychlorinated biphenyls
(PCBs) and dioxins are more susceptible to infectious diseases.
This project, which is part of the execution of the National Implementation Plan for the Stockholm Convention on Persistent Organic Pollutants (POPs), addresses the sources of polychlorinated biphenyls
(PCBs) in Tunisia, such as Oils and wastes and aims to eliminate equipment and materials that contain and / or are contaminated with PCBs.
if found in Inland and migratory fish should not be over 2.0 ppm and if found in marine fish, crustaceans and mollusks should not be 0.5 ppm.
In the case of polychlorinated biphenyls
, the mortality in the highest quintile of fat mass was only one-fifth of that in the lowest quintile.
Firefighters working in the rubble of the World Trade Center were exposed to potentially hazardous aerosolized dust consisting of pulverized cement, glass fibers, asbestos, lead, polycyclic aromatic hydrocarbons, polychlorinated biphenyls
, and polychlorinated furans and dioxins produced as combustion byproducts from the collapsed and burning buildings.
(PCBs) are a family of 209 synthetic hydrocarbons once extensively used in a variety of industrial applications as coolants or lubricants.
Chemical analysis simultaneously conducted showed higher than normal levels of dioxins in the liver, muscle, and fat, ie, polychlorinated dibenzodioxins, polychlorinated dibenzo-furans, and coplanar polychlorinated biphenyls
. The present results, together with those of relevant previous studies, strongly suggest an association between these pollutants and thyroid lesions in the great cormorant.
SAN FRANCISCO -- Greater levels of polychlorinated biphenyls
in the blood were associated with worse neuropsychological executive functioning in a study of 276 adults, Richard F.
However, as a new link in the Great Lakes food chain, Ricciardi worries, the fatty crustacean could boost concentrations of pollutants such as polychlorinated biphenyls
in the larger fish.
One possibility is that persistent organochlorine pollutants such as polychlorinated biphenyls
(PCBs) elicit immunotoxic effects that influence the production of specific antibodies.
"The studies of pesticides and other contaminants that are very common, such as mercury, lead and polychlorinated biphenyls
(PCBs), show that all are decreasing IQ levels," says Guillette.
They show that ministers this week (Tues) ordered that aldrin, chlordane, dieldrin, endrin, heptachlor, hexachlorobenzene, mirex, toxaphene, polychlorinated biphenyls
(PCB), DDT, chlordecone, the sum of alpha, beta- and gamma-HCH, and hexabromobiphenyl be present in wastes at concentrations not exceeding 50 mg/kg.
