PCBs – The World’s Greatest Hidden Threat

PCB’s are a major threat to world health yet their hardly dicsussed in terms of major world problems. Lets look at the facts

PCB – or PolyChlorinated Biphenyls was a great step forward for industrial chemistry. They were widely marketed in the 1930s onward and have been used as coolants and lubricants in transformers, capacitors, and other electrical equipment because they don’t burn easily and are good insulators.

Products made before 1977 (in the United States and Europe) that may contain PCBs include old fluorescent lighting fixtures and electrical devices containing PCB capacitors, and old microscope and hydraulic oils. The manufacture of PCBs was stopped in the US in 1977 because of massive evidence that PCBs build up in the environment and can cause harmful health effects.

The truth is that PCBs are extremely stable in the environment and do not biodegrade. They are a pollutant without equal.

PCBs were used because of their special qualities, such as:

o low vapor pressure
