Wood smoke also contains organic compounds such as benzopyrenes, dibenzanthracenes and dibenzocarbazoles, and other toxic compounds such as aldehydes, phenols and cresols.
Four compounds (anthracene, chrysene, benzopyrenes, and perylene) were identified directly by comparison with each of their respective deuterated standards.
Its combustion produces carcinogenic compounds such as benzopyrenes.
Thus the monograph on benzopyrenes has a series of chapters on environmental occurrence and analysis of these compounds.
