Comparative analysis of reactive oxygen species in cigarette smoke under two machine smoking regimes (ISO and Canadian intense conditions) from selected Chinese cigarette brands

Cigarette smoke can cause cellular oxidative stress and contributes to various adverse health effects associated with smoke exposure, partially due to reactive oxygen species (ROS) present in cigarette smoke. The purpose of present work is to evaluate toxic potential of selected Chinese blended and flue-cured cigarettes in terms of ROS quantification and effect of different smoking behaviors on the deliveries of ROS in...
