Description:
Problem: Estimate children’s blood lead levels (BLLs) for the U.S. residential population, given multimedia exposures from drinking water, soil, dust, air, and food Stakeholders: EPA Office of Water and other Program Offices, public health community Approach: Probabilistic analysis using coupled EPA’s SHEDS Multimedia and IEUBK models Model evaluation using CDC NHANES BLLs data Determined relationship between daily average drinking water Pb concentrations & BLLs for specified scenarios Quantified relative exposure pathway contributions across population distributions Identified most important factors affecting BLLs
