Pollutant Information: Benzo[a]pyrene 

About Benzo[a]pyrene

Category: Air pollutants

Benzo[a]pyrene (BaP) is of concern because of its effect on human health.  It is part of the group of Polycyclic Aromatic Hydrocarbons (PAHs) and is recognized as one of the most carcinogenic of the group. Emissions have decreased by 96% since 1990. Almost all of this reduction is due to the banning of stubble burning in 1993, since this source contributed 86% of emissions in 1990. Most of the rest of the reduction was due to improved control of emissions from aluminium production through the 1990s.  Since 2000, UK emissions have increased by 11%.  This is because emissions from residential sector combustion have grown due to increasing use of wood as a domestic fuel.
