The project is aimed to ensure minimazation of Polychlorinated biphenyl
relases and subsequent health and environmental implacts through systematic capacity development for sound Polychlorinated biphenyl
management in the country.

There was no significant association between polychlorinated biphenyl

Aroclors) typically consist of 60-90 of the 209 possible congeners, each of which differs in the positions and/or numbers of chlorines on the biphenyl
The directive requires that all new electrical equipment shipped to the European market after July 2006 contain less than maximum levels of the substances such as heavy metals (lead, cadmium, mercury, hexavalent chromium) and bromated flame retardants (polybromated biphenyl
or polyborminated diphenyl ethers).
First, polybrominated biphenyl
exposures have been associated with earlier menarche in girls, whereas experimental models show delayed puberty, a discordance that may be due to timing of exposure (Blanck et al.
The RoHS directive was established by the European Parliament and the Council of the European Union, requiring that electronics manufacturers not exceed new minimum acceptable levels of the following hazardous substances: lead, hexavalent chromium, mercury, polybrominated biphenyl
, cadmium and polybrominated diphenyl ether.
The six substances covered under the RoHS mandate are lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls
and polybrominated biphenyl
