Abstract

It is intended, in this paper, to discuss rainwater chemical composition in Cuiabá City, using the Urban Climate System (U.C.S.) perspective, considering sources emissions, topographical and geographic characteristics, and Man-Nature relationship. The samples were collected between 02/21 and 07/02/2006, which represent the end of the wet season and the beginning of the dry season. Acidity (pH measure), electric conductivity, nitrate, sulphate, chloride, nitrite and phosphate anions concentration were determined from 38 samples in which low anions concentrations were observed. These results indicate that Cuiabá City, being a continental area, has not been impacted with the acid rain phenomenon. The influence of the number of previous days without rain in the chemical composition variability was also evaluated.
