QUITERIO, Simone Lorena et al. Use of dust and air as indicators of environmental pollution in areas adjacent to a source of stationary lead emission. Cad. Saúde Pública [online]. 2001, vol.17, n.3, pp. 501-508. ISSN 1678-4464. http://dx.doi.org/10.1590/S0102-311X2001000300006.
This study measured lead concentrations in both the outdoor air and household dust from houses located around a lead-acid battery repair shop. Such installations are one of the largest sources of lead exposure, since outdated technology is still used, coupled with the lack of strict air-quality control programs. Measurements of the air lead concentration around the repair shop were carried out at 6 points, approximately 25 and 500m from the shop. Over 50% of the air samples exceeded the limit of 1.5µg Pb.m-3 (range 0.03 - 183.3µg Pb.m-3). House dust samples were collected from 6 places in houses located at approximately 25, 50, and 500m from the repair shop, and the concentration of 1,500µg Pb.m-2 for lead in house dust was exceeded in 44% of the samples, with results varying from 2.2 to 54,338.9µg Pb.m-2.
