Avaliação dos solos e das águas nas áreas de influência de disposição de resíduos sólidos urbanos de Humaitá, Amazonas

Abstract

The areas used for disposal of urban solid waste — usually represented by the “dumps” — are potential sources of pollution, negatively influencing the quality of human life and environmental health in the regions under their influence. The aim of this study was to evaluate changes in soil and water in the disposal area of the urban solid waste of Humaitá, Amazonas, Brazil. The study was conducted on soil of native forest, natural field and in the solid waste disposal area, as well as in the water courses near the area of solid waste disposal. The low clay levels found in the soil of the study area do not make it suitable for solid waste disposal. The levels of heavy metals in soil are within the limits allowed by law. And only iron in the water is above the limits allowed. The index of quality of water was good.
