Polychlorinated naphthalene

Polychlorated naphtalenes, or PCN are the products that are made when naphtalene is treated with chlorine. In many respects, these substances are similar to Polychlorinated biphenyls, or PCBs.[1]

Uses

PCNs are used as insicticides and as fungicides. Wood is often treated with PCNs to make it more resistant. Sometimes, they are used to produce water-resistant dyes and colors. Sometimes, they replaces PCBs in the form of artificial resins.[2]

Hazards

Like PCBs, they are very poisonous. They cause chloracne when they have direct contact with the skin.[3] There are other symptoms, such as being irritable, losing weight, and certain liver dysfunctions.[4][4] Because, like PCBs, they take a long time to decay, they were classified as persistent organic pollutant in 2015.[5]
