Comparative Studies of Environmentally Persistent Free Radicals on Total Particulate Matter Collected from Electronic and Tobacco Cigarettes.
Hasan F, Khachatryan L, Lomnicki S. Hasan F, et al. Environ Sci Technol. 2020 May 5;54(9):5710-5718. doi: 10.1021/acs.est.0c00351. Epub 2020 Apr 14. Environ Sci Technol. 2020. PMID: 32267684
Comparable concentrations of EPFRs were detected in both sidestream (8.05 1.32) 10(4) pmol/g and mainstream TPM (7.41 0.85) 10(4) pmol/g of conventional cigarettes. TPM exposure to air resulted in long-lived oxygen centered, secondary radicals with EPR g values of 2.0041 f …
