Research Interests

My primary research objectives are (1) the determination of the human health effects of exposures to waste materials and (2) the determination of residential housing factors responsible for pediatric lead poisoning. The former includes both occupational and public exposures and involves biological as well as chemical agents. The wastewater exposure situations are land application, sludge composting, conventional wastewater treatment and sewer maintenance. Public exposures include air and drinking water co...
