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.

We detected PAHs with higher molecular mass, ranging as high as 1,000 amu (not shown), with compounds in the range 228-366 amu well represented (Figure 2; M+[H.sup.*+] masses > 500 not shown) and in large amounts [1,000-5,000 cigarette equivalents of benzofluoranthenes + benzopyrenes
