ANÁLISE DE ELEMENTOS E COMPOSTOS QUÍMICOS NA ÁGUA DAS ESTAÇÕES DE TRATAMENTO DE ÁGUA (ETA´s) EM 6 (SEIS) MUNICÍPIOS DO SUDOESTE GOIANO E SUA CORRELAÇÃO COM A SAÚDE.

Abstract

Water is becoming time after time a rare product and its quality is also getting worse, however, the quality of water shows a close relation with the environment balance and human health. Water sources can suffer natural and anthropic contaminations, showing even elements and chemistry complex in anomalous concentrations. This work has the goal to conduct a geochemistry research of treated water samples taken from Water Treatment Stations and also an epidemiologic research in six cities from the Southwest region of Goiás State in Brasil. The methodology used to determine the concentrations of multielements , was ICP-AES and liquid chromatography. From these results found, data had a statistic treatment and then, it was made matrixes of correlation and geochemistry maps. It was found an

sample, from that, it was noticed that this contamination problably comes from Nitrogen Pesticides used in local agriculture, because the soy bean crops are in areas that are very close to the stream that supply the Water treatment Station of the city Acreuna, with a possible impact on deaths in the region.
