Abstract
In this study, an inter-standard quantitative method was used for determination of PAHs in gum-based chewing tobacco by GC-MS/MS. Under the control of the optimized experimental conditions, the LODs and the LOQs of 19 target PAHs could achieve 0.04~0.14 ng/mL and 0.14~0.46 ng/mL, respectively, while the linear correlation efficiencies were larger than 0.998 for all PAHs. With three different adding-levels, the recovery rates for all PAHs ranging from 92.26% to 109.46%. And the Intra-assay and Inter-assay precisions for the PAHs were 0.77%~3.85% and 1.57%~4.86%, respectively. The method developed was reliable and suitable for routine analysis of PAHs, and was verified to be one of the effective methods for quality control of gum-based chewing tobacco.
