The broad category of human-made organic chemicals known as chlorinated hydrogens includes polychlorinated biphenyls (or PCBs). From 1929 to 1979, PCBs were produced all over the world. In 1979, the United States banned their production. They come in a variety of consistency, from thin, translucent liquids to thick, waxy solids that are yellow or black.
This chemical can prove to be dangerous if not disposed of carefully. If you happen to work in this industry, it is advised to take the help of a good PCBs disposal company through https://benzoil.com.au/services/polychlorinated-biphenyls-pcbs/.
Because of their nonflammability and chemical stability, high boiling points, and electrical insulation properties, PCBs have been used in many industrial and commercial applications, including heat transfer and hydraulic equipment, paints, rubber products, plasticizers, pigments, dyes, and carbonless copy papers, as well as in other industrial applications.

PCBs can persist in the environment and build up in the organic portion of the media they are present in. PCBs are found in water, soil, and air. However, they can easily accumulate in tissue and sediment, and they are found most frequently in aquatic food webs.
PCBs are actually made up of 209 chemicals.PCBs are most commonly exposed to humans through fish consumption. Then, they can be found in agricultural products like dairy, beef, and, to a lesser degree, many vegetable crops.
Both animal and human studies have shown that PCBs are associated with development delays after in-utero exposures. PCBs are also known to have reproductive effects, particularly in wildlife, and immunological effects.
