COMPARISON OF IEUBK MODEL PREDICTIONS AND ACTUAL BLOOD LEAD VALUES ATA FORMER BATTERY RECYCLING SITE

This paper presents an evaluation of US EPA's integrated exposureuptak e biokinetic model for lead (IEUBK model) using data obtained during e mergency removal operations at a former lead-acid battery recycling pl ant and the surrounding community. Data employed in the study include soil lead and interior dust lead, air lead levels collected at the sit e perimeter, drinking water lead levels at the community water main an d blood lead data collected from an annual blood lead monitoring progr amme conducted over a four year period during the remediation activiti es. Geometric mean soil and dust concentrations were found to be a bet ter predictor of blood lead than arithmetic mean data. However, weight based dust lead data were believed to be an inappropriate measure of dust lead levels. Estimates of household dust lead concentrations base d upon surface loading data (mug m-2) yielded blood lead predictions w hich were more consistent with data collected in the blood lead monito ring programme.
