2017 Collaborative Study on Benzo[a]pyrene in Tobacco Products

TTPA Technical Document

July 2017

In March 2016, the CORESTA Smokeless Tobacco Sub-Group (STS) (now named Tobacco and Tobacco Products Analytes Sub-Group, TTPA) published CORESTA Recommended Method No. 82 “Determination of Benzo[a]pyrene in Tobacco Products by GC-MS (CRM N° 82). In May 2016, four new CORESTA Reference Products (CRPs) were manufactured. In a characterisation study of the new CRPs, it was noted that the reproducibility (R) results showed greater variability than expected for CRP2.1 and CRP3.1 - this was attributed to the CRPs having higher levels of benzo[a]pyrene (B[a]P) than analysed previously. This collaborative study was organised to determine if the modification to the CRM would improve the reproducibility (R) values for samples with high levels of B[a]P.

The results of the study demonstrated that the method modifications did improve the reproducibility (R) results for CRP2.1 and CRP3.1, and CRM 82 was subsequently revised and updated.
