ABSTRACT
Rainfall is one of the primary nutrient inputs to vegetation and its chemical composition is
dependent on air quality as falling rain scavenges gaseous and particulate emissions from natural,
industrial, and agricultural activities. The objective of this study was to evaluate whether the
vegetation burn in a region of the Pampa biome influences the pH and chemical composition
(anions) in incident rainfall. Nitrate, sulfate, and chloride concentrations, as well as the pH of
the rainwater, were influenced by suspended particles in the atmosphere from biomass burning
of native grassland and pasture renewal. The rainwater was acidified by, ash, and soot, which
introduced large amounts of chloride and sulfate into the ecosystems caused by burning vegetation.
Keywords: rainwater acidification, anions, atmospheric pollution.
