Dr. Kissel has a history of research related to human exposure to environmental contaminants. One aspect of this work involves characterization of human dermal contact with soils and sediments. Results of those studies have been incorporated directly into EPA guidance documents, such as the Exposure Factors Handbook, that are used by persons involved in cleanup of Superfund sites or other contaminated lands. Dr. Kissel and his students have also investigated the efficiency of dermal absorption of contaminants from environmental matrices. A second research focus area is evaluation of the predictive capability of regulatory exposure models. Dr. Kissel was awarded an EPA STAR grant to examine correspondence between output from probabilistic aggregate exposure models and observed levels of urinary biomarkers of pesticide exposure. A NIOSH-funded project involving prediction of chemical decontamination of skin by washing began in September 2007. Current activity also includes investigation of chronic SVOC exposures in indoor environments. Recent journal publications are listed below.
