THE SEASONALITY OF AIR POLLUTION BY A PERMANENT SPOT OF MINING IN GOIÁS NORTHWESTERN

Abstract

Atmospheric pollution affects human health and the environment. There are many pollutions spots but they are mainly from industries, transport, energetic production, agriculture and mining. In atmosphere many chemical reactions of substances from natural, anthropic that disperse and react between then and other elements that already exists on atmosphere. The permanent spots of mining are located on delimited, allowing us to assess the environmental impact and the released substances of this activity. This study aims to verify the seasonality effect of pollutants emission of mining activity spots on Goiás northwestern. For that, we sample the substances at these areas, using an Isocinect collector of atmospheric pollutants – CIPA, and Gas analyser 3000 Eurotron and we made some laboratory exams to set the concentration of them, before and later the rock detonation process. The period of the study was on dry and wet periods of 2012. We analyse data through Kruskall-Wallis test and Spermann correlation. The samples was adequate and seems to be sufficient. The substances released by chimney agree with environmental laws. However, we suggest that must be an environmental passive to mining activities as well as environmental laws and environmental inspection improvement of these activities.
