(TAP) -- The first phase of the project for environmentally sound management of Polychlorinated biphenyls
(PCB) in Tunisia was announced on Monday by the National Agency for Waste Management (ANGED), at a news conference organised in Tunis for this purpose.
The report also focuses on three particular environmental hazards: the health effects of climate change, lead-free drinking water and polychlorinated biphenyls
, which are banned toxic chemicals that are still found in the environment.
Mashnouk signed on Tuesday a cooperation agreement with Electricite du Liban's Chairman Kamal Hayek to execute the Polychlorinated Biphenyls
(POP) management in the electricity sector and implement a national strategy to get rid of the Polychlorinated biphenyls
High stability, the quality that made polychlorinated biphenyls
(PCBs) so useful in hundreds of industrial and commercial applications during the mid-1900s, has ensured the compounds' continuing presence in the environment despite decades of banned and restricted use.
Axially chiral biphenyls
having conformationally restricted and unresticted cores were investigated for dipole moment at B3LYP/6-31G(d) method of DFT(density functional theory).
, polybrominated diphenyl ethers, polybrominated biphenyls
, phthalates, bisphenol-A and halogens such as fluoride, bromide and iodide can bind to thyroid hormone receptors and exert negative effects.
(PCBs) are a family of 209 synthetic hydrocarbons once extensively used in a variety of industrial applications as coolants or lubricants.
When sources that emit at wavelengths above 300nm are employed, such as sunlight, the absorption of light by the polychlorinated biphenyls
is very small.
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.
The restriction of Use of Certain Hazardous Substances in Electrical and Electronic Equipment (RoHS) Directive limits the use of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls
and two polybrominated diphenyl ethers.
