Abstract

Lead stable isotope ratio (IR) analysis by inductively coupled plasma mass spectrometry was used to examine the relationship between sources of Pb in 22 dust wipe samples collected from 10 homes in Jersey City, NJ. Common lead sources examined included interior lead-based paints, exterior soils and street dusts, and indoor air. High correlations between IRs of wipe samples and both street dusts and exterior soils indicated these two exterior sources were indistinguishable. They were treated as a single exterior source in a source apportionment using IR matching and a simple mixing model. The upper-bound estimate of the contribution of interior lead-based paints to 10 floor- and eight sill-wipe samples was 56% and 50%, respectively. It was not possible to apportion sources in four of the 22 samples because wipe sample IRs were outside the range of measured sources. Examination of means obscures the variability in the data, however, as eight of the 18 apportioned samples matched interior or exterior source media. In most cases, however, sources from outside the home contribute as much Pb to house dust wipe samples as interior lead-based paints. Copyright (C) 1998 Elsevier Science B.V. All rights reserved.
