PhilaU Researchers Publish Study on Third-Hand Smoke Tyler Fleming ’12, Chris Anderson ’12, Sarang Amin ’12 and faculty research mentor Jeff Ashley, associate professor of chemistry, published a paper on third-hand smoke in the October Journal of Integrated Environmental Assessment and Management, a respected publication highlighting advances in the field of environmental toxicology and assessment. Fleming, Anderson and Amin conducted research on the levels of a group of cancercausing chemicals in third-hand smoke, which is the residue from tobacco smoke that is absorbed by smokers’ clothing and skin, as well as surrounding surfaces such as walls, carpets and furniture. The study, “Third-Hand Tobacco Smoke: Significant Vector for PAH Exposure or Non-Issue?,” concludes that after smoking even one cigarette, smokers have higher residues of these chemicals on their bodies and clothes. This may increase chemical exposures to non-smokers, especially infants and children, who come in contact with third-hand smoke residues. 54 • Entrepreneurial DNA
