VANZ, Argeu; MIRLEAN, Nicolai  and  BAISCH, Paulo. Evaluation of the air pollution by particulate lead: geochemical approach. Quím. Nova [online]. 2003, vol.26, n.1, pp.25-29. ISSN 0100-4042.

High lead concentrations up to 5478 mg kg-1 were detected in dry atmospheric precipitations in Rio Grande city and adjacent area. Lead anomalies cover up to 30% of the study area. Lead concentration measurement in dry atmospheric precipitation and suspended particulate matter provides a possibility to detect concentrations above lead threshold in the air. The most impacted areas are fishermen's villages. The most possible source of lead in the air is uncontrolled sub industrial activity of local population

Keywords : lead; precipitation; air pollution.
