A comparative study of major brands of domestic and imported cigarettes saled in market has been conducted. The total amounts of total particulate matter(TPM), tar and nicotine delivered from cigarettes, as well as the amounts of tar, nicotine in puff by puff were determined in the mainstream smoke of 6 brands.

Results showed that the amounts of TPM and tar delivered from domestic brands were similar to the imported brands and the amounts of total nicotine delivered from domestic brands were higher than those of imported brands. As the domestic cigarettes nicotine/tar(N/T X 100) ratio was 9.5-10.3, the imported one's was 5.6-8.1. However, the amounts of tar and nicotine in puff by puff for the domestic brands were lower than those of the imported cigarettes and the relative amounts of vapour phase in 3rd puff smoke for the domestic cigarettes were lower than those of the imported cigarettes.
