The project will develop lead exposure indices associated with the 200 houses included in the ongoing study of immunologic effects of lead exposure of a population living near a secondary lead smelter in Cairo, Egypt. In addition to exposure from air, this proposal will also develop quantitative indices of exposure from lead in dust both interior and exterior areas and in soil. Because lead in paint has recently been detected in paint in a countries, where it had not been previously found, the extent and level of lead-based paint that may exist in the housing will also be determined. The analytical method to be used is field portable X-Ray Fluorescence which is a low cost technology capable of measuring lead in a variety of media (air, soil, dust, paint and other solid materials), can provide results within a short period of time that can be conveyed to stakeholders, and is one with which investigators at the UC collaborating institution, the Department of Environmental Health of the University of Cincinnati, has extensive experience. Investigators in the Department of Industrial Medicine and Occupational Diseases currently is investigating the immunology effects of lead on the population near the lead smelter. There is evidence that immumologic effects occur before the presence of more traditional toxicological manifestations and thus could serve as an early warning mechanism of impending disease. The quantitative data developed in the proposed study will provide valuable exposure information for use in developing dose-response relationships.
