Ocupação do relevo e fatores de contaminação do solo por metais pesados. Uma análise do cemitério São José na cidade de Ituiutaba - MG

Abstract

This work presents an analysis of soil occupation and soil contamination in the São José cemetery in the city of Ituiutaba - MG. By means of the geography one can make an analysis of the soil element, being made its chemical analysis to determine the values of heavy metals and physical analysis to know its texture. A new methodology is proposed to classify the soils of this type of occupation. In chapter one, the relation between man and nature is discussed, as well as the occupation of relief for the implantation and use of the cemeteries. This relationship is the choice of the appropriate relief compartment, the use and occupation of the soil directed to these areas. It also deals with the history of burials and the use of cemeteries and a general approach to Brazilian cemeteries. Chapter two makes a characterization of the study area where it is the comparison of the conditions found in relation to the CONAMA regulations, presenting the cases found in the current condition in which the cemetery is located. The final chapter brings the results of the research, starting with the relation of the urban environmental impacts in graveyard areas. The final step is the analysis of the soil that is the central theme of the research. The texture and chemical parameters for the heavy metals values - Ba, Cu, Zn and Cr - are presented, discussing the impacts caused to the soil and to human health through maps showing the distribution of the samples and their values and graphs compare these values to those permitted by both national and state legislation.
