The project, led by the Ministry of Environment and Sustainable Development, will achieve this goal by implementing environmental management systems of polychlorinated biphenyls
in the energy sector stakeholders and strengthen the structure of provincial environmental authorities to ensure control and compliance Plan.

The production of polychlorinated biphenyls
(PCBs) was banned worldwide by 1977, but the chemicals linger in the environment at hazardous waste sites, in contaminated fish and food supplies, and in old appliances.
RM 8504, Transformer Oil, is intended to be used as a diluent oil with transformer oil Standard Reference Materials (SRMs) 3075 to 3080 and SRM 3090  when developing and validating methods for the determination of polychlorinated biphenyls
(PCBs) as Aroclors (1) in transformer oil or similar matrices.
Burkholderia xenovarans (strain LB400) is a bacterium found in soil that has the ability to degrade polychlorinated biphenyls
and other contaminants.
The State of Wisconsin Department of Natural Resources (W-DNR), Madison, Wisconsin, USA says the long-awaited cleanup of polychlorinated biphenyls
(PCB) began the week of September 13 at two of Wisconsin's worst PCB contamination sites, while work at third site moved into a critical phase during the same period.
In the final part, there are chapters summarising a wide range of other chemical residues in food, from xenoestrogens/endocrine disruptors and dietary estrogens to polycyclic aromatic hydrocarbons, dioxins and polychlorinated biphenyls
The US government banned PCBs, or polychlorinated biphenyls
, in 1979.
(PCBs) are manmade chemicals and well-known contaminants prevalent in both terrestrial and aquatic ecosystems.
It is valuable in determining levels of polychlorinated biphenyls
in groundwater samples and facilitates the assay of many recycled organics and other materials such as pesticides, pharmaceuticals, polymers, and hydrocarbons.
