In order to investigate the effects of material parameters, including air permeability of cigarette paper (APCP), air permeability of tipping paper (APTP), air permeability of plug wrapper (APPW), tow specifications (tow index I) of combined filter at mouth end (ITME) and tobacco end (ITTE), addition rates of filter additive A (benzoin resin, ARAA) and filter additive B (bergamot oil, ARAB), on the benzo[a]pyrene (B[a]P) delivery in mainstream cigarette smoke, the test cigarettes with various material combinations were prepared. The B[a]P delivery in mainstream cigarette smoke was analyzed against the said factors, and the optimized material combinations were verified. The results showed that: 1) APPW did not influence B[a]P delivery significantly, the other factors in the order of their effects on B[a]P delivery were ARAB > ITTE> ITME=APCP>APTP >ARAA, and interacted each other. 2) The optimized material combination for low B[a]P delivery were: APCP 50 CU, APTP 400 CU, ITTE 3.5 Y/34000, ITME 3.0 Y/35000, ARAA 2.436 mg/cig, and ARAB 2.100 mg/cig. 3) Comparing with monoacetate filter, the B[a]P delivery in mainstream smoke of cigarettes prepared with the optimized material combination decreased by 48.87%. ©, 2015, Editorial Office of Tobacco Science and Technology.
