Tobacco Nitrate and Free Radical Levels in the Mainstream Smoke of US Cigarette Brands.

ABSTRACT: Tobacco nitrate levels have been known to impact the levels of toxicants such as polyaromatic hydrocarbons and tobacco-specific nitrosamines (TSNAs) produced during smoking. Recent work in our group showed that the intrinsic nitrate levels in individual tobacco varieties also have a large influence on the formation of gas-phase (GP) free radicals in the mainstream smoke of cigarettes produced with a single tobacco variety. As tobacco nitrate content is a potential target for future regulatory policies, we investigated whether the levels of GP free radicals in the smoke from commercially available cigarettes is also dependent on the nitrate content in the corresponding tobacco blends. GP and particulate-phase (PP) free radical yields in mainstream smoke produced from 25 popular US cigarette
