RELATIONSHIPS OF POLYCYCLIC AROMATIC HYDROCARBON YIELDS WITH PARTICULATE MATTER (WATER AND NICOTINE FREE) YIELDS IN MAINSTREAM AND SIDESTREAM CIGARETTE-SMOKE

Machine generated polycyclic aromatic hydrocarbon (PAH) yields, exempl ified by benzo[b]fluoranthene (B[b]F), benzo[k]fluoranthene (B[k]F) an d benzo[a]pyrene (B[a]P), have been measured in mainstream cigarette s moke (MCS) and sidestream cigarette smoke (SCS). Relationships are app arent, with exceptions which are discussed, for each PAH yield with th e particulate matter (water and nicotine free) yield in both MCS and S CS. For approximately 60% of cigarette sales in the UK, the sales weig hted yield for B[b]F, B[k]F and B[a]P, respectively are 10.4, 5.1 and 13.4 ng/cigarette (cig) in MCS and 154,42 and 161 ng/cig in SCS.
