Acid rain: a case study at the Universidade de Sao Paulo campus, Sao Paulo State, Brazil; Chuva acida: estudo de caso no campus USP/SP

Abstract

The phenomena called acid rain is considered, by many researchers, one of the most serious environmental problem. This work has the aim of showing, in a theoretical and practical study, the problems caused by the atmospheric-pollutant emission, through natural or anthropogenic sources. In a period of 1 year (nov/94-nov/95), it was realized a practical work on rainwater, which consisted of collecting and, afterwards, analysing some physical and chemical parameters of this water, such as acidity, ionic concentrations, etc, with the purpose of characterizing the rainwater in Cidade Universitaria (SP, Brazil). After ending the practical part, it was possible to observe a 1,236.71 mm/y pluviosity, characterized by rainy summer and dry winter. The chemical-constituent-concentration analysis show us the predominance of SO{sup 2-}{sub 4} and Ca{sup 2+}, and a continental-origin water). The region of sao Paulo (Brazil), site of this study, is one of the largest metropolitan and industrialized areas of the world, which includes 18 million people, beside to an enormous industrial and vehicular complex. The acidity in the rain water is a complex problem and it must be treated by a range of disciplines to have a better comprehension of the cause/effects of the acid rain. (author) 96 refs., 28  More>>
