Epoxybenzopyrene

There are many things in life that we don’t understand, but are very harmful to our bodies. For example, benzopyrene epoxy is something that exists in people's lives but is relatively rare. It mainly exists in coal tar and the smoke produced by the burning of some tobacco and wood. It is a mutagen and carcinogen, which poses a great threat to the human body. The following is a detailed introduction to it.

Benzoapyrene (Benzoapyrene), chemical formula: C20H12, English name BaP, is a pentacyclic polycyclic aromatic hydrocarbon. Crystallizes as a yellow solid. This substance is produced during incomplete combustion at temperatures between 300 and 600°C. Benzo(a)pyrene is found in coal tar, which can be found in car exhaust (especially diesel engines), tobacco and wood smoke, and in charcoal-grilled foods. Benzopyrene is a mutagen and carcinogen that has been linked to many cancers since the 18th century. Its metabolite in the body, dihydroxyepoxybenzopyrene, produces carcinogenic substances.
