Diagnóstico da disposição final de resíduos sólidos no vazadouro do município de Manicoré-AM

Abstract

In most Brazilian cities, there is no system for collecting, treating and disposing of waste properly. The locations that receive waste have three main forms, which are the dump, sanitary landfill and controlled landfill. The aim of this research was to diagnose the influence of the Manicoré dump, in the state of Amazonas, by carrying out chemical analyses of soil pollutants and physical-chemical analyses of surface water, recognizing the enterprise as a threat to environmental and public health. In order to georeference and map the areas, it was necessary to visit the study area on site to check the coordinates and take photographs. Observations made at the site showed that waste is disposed of directly on the ground, without protection or subsequent covering. Due to this problem, it was proposed to characterize the toxic metals present in the soil in the area of the dump, in which eight sampling points were selected distributed around the perimeter, the depth for all was 0-80cm. The elements Copper (Cu), Cadmium (Cd), Lead (Pb), Manganese (Mn), Chromium (Cr), Iron (Fe), Zinc (Zn), Cobalt (Co), Nickel (Ni), Potassium (K) and Sodium (Na) were defined for chemical analysis of the soil, along with the variables Organic Matter and pH. The water sample collected had its parameters measured in a specialized laboratory. The results obtained provide crucial information for The water samples collected had their parameters measured in a specialized laboratory. The results obtained provide crucial information for decision-making and the promotion of public policies aimed at this issue, which affects quality of life in so many ways. The research did not reveal the presence of toxic metals at relevant levels, but it did reveal the presence of coliforms in the wells adjacent to the dump.
