Estimation of mouth level exposure to smoke constituents of cigarettes with different tar levels using filter analysis.

Highlights: [•] Mouth level exposure to smoke constituents was estimated using filter analysis. [•] Calibration curves for 41 out of 47 smoke constituents were generated. [•] 780 smokers were recruited in Japan to estimate MLE to selected smoke constituents. [•] Most of measured MLE were positively correlated with ISO Tar. [•] Most of measured MLE were negatively correlated with HCI yields per mg nicotine. [Copyright &y& Elsevier]
