Pollutant Information: Benzo[a]pyrene 

About Benzo[a]pyrene

Category: Air pollutants

Benzo[a]pyrene (BaP) is part of the group of Polycyclic Aromatic Hydrocarbons (PAHs) and is recognised as one of the most carcinogenic of the group. Emissions have decreased by 88% since 1990 and almost all of this reduction is due to reduced emissions from aluminium production and the banning of stubble burning in 1993. However, while emissions decreased consistently between 1990 and 2002, subsequently they have stabilised and even increased in some recent years, predominantly due to increased emissions from domestic combustion. This is due to a combination of fairly stable demand for coal and increasing use of wood as a domestic fuel.
