Although PCBs pose a serious threat to global health, they are not considered a major problem. Let's examine the facts.The great leap forward in industrial chemistry was the PolyChlorinated Biphenyls (PCB). They were popularly marketed from the 1930s and used as coolants or lubricants in transformers and capacitors.
Products manufactured before 1977 in the United States and Europe may contain PCBs. These include old fluorescent lighting fixtures, electrical devices containing capacitors PCBs, old microscopes, and hydraulic oils. In 1977, the US stopped the manufacture of PCBs due to extensive evidence that PCBs can build up in the environment.

PCBs are very stable in the environment, and they do not biodegrade. They are an unrivaled pollutant.
Because of their unique qualities, PCBs were chosen for their use.
- Low vapor pressure
EXTREME stability, non-biodegradability
High boiling point 278 to 415C
Low solubility in water: 20 C, 25 ppb
Good solubility in organic solvents and lubricants
Good thermal conduction
high dielectric constant
High-temperature Resistance
It is an environmental pollutant, however, it is unrivaled. It accumulates in animal tissues, with teratogenic and pathogenic effects. It is known to be carcinogenic and can, under certain conditions, turn into dioxin, which is a highly toxic poison.
During their manufacturing, disposal, or use, PCBs can enter the soil, air, and water. They can also be released into the environment by accidental spillages during transformer servicing or transport. So, when working with this material, we have to be extremely careful.
