Avaliação da contaminação causada no perfil do solo, pelo deslocamento de alguns elementos químicos, em uma área do lixão da cidade de Paripueira-AL

Abstract

The work had as prerogative to evaluate the contamination caused in the soil profile, by the displacement of some chemical elements in an area of the garbage dump in the city of Paripueira-AL through a chemical study of the soil profile. For this purpose, a study was carried Therefore, a study was carried out in a 2x6 factorial statistical model (with and without garbage x six depths). The work had the following sequence: construction of trenches, soil collection in different depths in the profile, chemical analysis of the soil in the laboratory, interpretation and technical comments, in addition to a review of the literature appropriate to the topic. Among the main results, it can be highlighted that urban waste, over time and after decomposition, did not cause contamination in the deeper layers of the studied soil, and in the comparison between areas with and without urban waste, it was observed that there was no contribution of chemical elements to soil layers below 20 centimeters. Although the contaminating substances did not reach deeper layers in this study, other studies of a microbiological nature may be necessary to obtain a broader view of the impacts on the soil and the water table.
