摘要：Influence of cigarette draw resistance between 860-1130Pa on Benz [a] Pyrene in mainstream cigarette smoke was carried out, and contribution to cigarette hazard index was also studied. The experimental results showed that the contribution degree of is uniform, which is different from variation of HCN, CO, crotonaldehyde and NNK. 1000Pa is the critical draw resistance, below and above 1000Pa an obvious variation of Benz [a] Pyrene appears. Contribution to cigarette hazard index was also analyzed, which proves that it is feasible and convincing to study variation of Benz [a] Pyrene and other smoke harmful components.
