Na, Ca, K, Mg e Cl Atmosféricos na Região Leste do Estado de São Paulo

Abstract

Rainwater and atmospheric particulate matter samples were systematically collected from July 1981 to August 1983 at three meteorological stations in the eastern part of the state of São Paulo. These samples were analyzed and sodium, calcium, potassium, magnesium and chloride contents were determined, as well as the total particle concentration. The results were correlated with some geoclimatic parameters which allowed us to draw inferences about the continent-ocean-atmosphere interactions. Wet and dry fluxes were also determined, and with the only exception of sodium at São José dos Campos, it was found the well-marked prevalence of the wet deposition for all studied elements.
