Environmental chemical study of the Murucupi river – Barcarena, PA, Brazil impacted area for the aluminum production
Abstract
The present work evaluate the chemical conditions of the Murucupi river with relationship to the physical-chemical parameters and the presence of chemical elements in the water and correlations. The Murucupi river is located in the amazon region close the aluminum production area. Were analyzed the major, minor and trace elements (Ca, Mg, Na, K, Fe, Al, Ba, Mn, Sr, Zn, Ni, Pb e Cu), and physical-chemical parameters, acidity, total alkalinity, organic matter, pH, turbidity, temperature, conductivity, dissolved oxygen (OD) and total hardness. 13 collection points were selected along this river. In relation to the physical-chemical parameters the pH and OD only presented values in non conformity with the strip of values established by the resolution 357/05 of CONAMA. In relation to the chemical elements were found only the aluminum (Al: 356.04µg/L) and the iron (Fe: 1080.80µg/L), were in non conformity with the legislation. This results shows the anthropogenic influence in the contamination of the Amazon rivers from the production of aluminum reject.
