Benzo[b]fluoranthene
A tracer of diesel exhaust in city air.
Benzo[b]fluoranthene is a PAH monitored in air quality measurements as an indicator of diesel exhaust and heating-related pollution. Its level in urban air rises in winter. For a smoker, though, the main source is not the street but the smoke itself.
Source: The substances are drawn from the U.S. Food and Drug Administration's list of harmful and potentially harmful constituents in tobacco products. Carcinogen classifications come from the International Agency for Research on Cancer (IARC).
