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

A new reference material (RM), RM 8504, has been prepared for use as a diluent oil with Aroclors in 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 in transformer oil or similar matrices.
Prior soil and sediment assessment has shown that the reserve land is heavily contaminated with pollutants such as polychlorinated biphenyls
, polyaromatic hydrocarbons, hexachlorobenzene, mirex, a variety of potentially toxic metals, volatile organic compounds, phthalates, and dioxins; many of these are known or suspected endocrine disruptors.
People covet wild salmon because it is leaner, tastier and contains no color dyes and fewer cancer-causing polychlorinated biphenyls
(PCBs) than its pen-raised cousin, according to Ecotrust's Salmon Nation.
Coming in July, EU Directive 2002/95/EC, "Restriction of Hazardous Substances" (RollS), will limit those metals plus polybrominated biphenyls
