ANÁLISE QUÍMICA DA ÁGUA NAS ESTAÇÕES DE TRATAMENTO DE ÁGUA (ETA s) DA REGIÃO METROPOLITANA DE GOIÂNIA-GO E SUA RELAÇÃO COM A SAÚDE

Abstract

Water is responsible for transporting minerals in the physiology of living beings, which makes human health dependent on its potability. As part of the work carried out by Company of Mineral Resources Research (Companhia de Pesquisas dos Recursos Minerais CPRM) in the Water Treatment Plants of the Goiás State, samples collected in 11 municipalities in the metropolitan region of Goiânia-GO were analyzed aiming at verifying the physical-chemical parameters and multielement composition of water (method ICP-OES and chromatography). The results obtained were compared to Brazilian and international standards of water quality and correlated with possible health problems that may be caused by excess or lack of some chemical elements present in living beings. Environmental alterations were identified in the municipality of Goianira-GO, with the presence of lead in the composition of the water that supplies the population. In Parque dos Girassóis, a neighborhood near the points where the water that supplies the municipality of Goianira-GO is collected, the presence of auto repair shops and junk yards was detected. These enterprises deal with car batteries and other products that contain lead in their composition and dispose of these materials directly into the soil. This causes the contamination of water and poses health risk to the local population.
