Cemeteries are potential sources of environmental impacts, mainly in terms of the risk of contamination of groundwater and surface water by microorganisms that proliferate during the processes of decomposition of bodies, in addition to the chemical substances released. This contaminated water, in turn, frequently ends up being used by the populations neighboring the cemeteries for animals, crops, etc. The main contaminant from cemeteries is necrochorume. The objective is to verify if the municipal cemetery of Araruna, considering its characteristics of location, type of soil, proximity with small properties and source of affluent, may be contaminated in soil and/or surface water. Holes were drilled at three different depths on the sides of graves with the burial of human bodies without any control of civil works, that is, directly in the ground. In addition, the collection of surface water in spring and tributary distant approximately 60 meters from the cemetery area. The water and soil samples were evaluated considering the standards established in CONAMA Resolution 420/2009 for the soil and CONAMA Resolution 357/2005 for the water samples for analysis of heavy metal patterns were carried out at the UFPR Laboratory Campo Mourão Campus PR. The result found showed changes that may be related to the characteristics of the local soil, but the possibility of interference due to the existence of a cemetery located upstream of this collection point about 60 meters is not ruled out. Soil metal analyzes were performed in an outsourced laboratory. The results presented in relation to metals in the soil, considering their profiles from 0 to 1.00 meters in depth, point to changes as the soil deepens to the point of burial of human bodies, where the results presented are superior to the ones presented. reference, which may be related to human decomposition because it is a soil with greater permeability and the presence of metal elements in the funerary urn. |
