  • NOTE: All cigarettes were smoked under ISO smoking regimen. Mainstream smoke emission constituents (TSNAs and PAHs) were normalized by tobacco weight consumed during smoking. Nitrate contents were normalized by tobacco weight.

  • * Ten PAHs listed in IARC monograph 83.

  • Statistical significant (P < 0.01).
