Seminar by Charles Weschler

Time: 9:00 -10:00

Dermal uptake directly from air for phthalates and other common chemicals 

Numerous studies over the past five years have indicated that indoor exposures are responsible for a significant fraction of the plasticizers, flame retardants, surfactants and other additives found in our bodies. Models based on fundamental physical chemistry indicate that some of these compounds are dermally absorbed from air or clothing at rates comparable to or larger than inhalation intake. Yet, with a few exceptions, this pathway has not been largely overlooked when performing exposure assessments. This talk will describe recent studies with human volunteers that confirm the importance of the dermal pathway for a number of common indoor pollutants.

About Charles J. Weschler

Environmental and Occupational Health Sciences Institute, Rutgers University

International Center for Indoor Environment and Energy, Technical University of Denmark

Professor Charles J. Weschler earned his Ph.D. in Chemistry from the University of Chicago and did Postdoctoral research at Northwestern University before joining Bell Laboratories. After 25 years at Bell Labs and its successor institutions, he accepted positions at the Environmental and Occupational Health Sciences Institute (EOHSI) at Rutgers University and the International Centre for Indoor Environment and Energy, Technical University of Denmark. For the past eight years he has also been a Visiting Professor at Tsinghua University. His research interests include chemicals present in indoor air, their sources and their fate; human exposure to these pollutants, including via the dermal pathway; chemical reactions among indoor pollutants with an emphasis on ozone-initiated chemistry; and redistribution of semi-volatile organic compounds (SVOCs) in indoors settings. Prof. Weschler has served on four National Academy of Sciences’ committees and, from 1999-2005, was a member of the US EPA’s Science Advisory Board. He has published over 150 peer-reviewed papers and has an h-index of 53 (Web of Science). He is an elected member of the International Academy of Indoor Air Sciences and has received the Pettenkofer Award, its highest honor.
