Abstract

This research aims to quantify and analyze the levels of soil contamination by heavy metals in three cemeteries\ud located in the city of Carazinho-RS, Brazil. The decomposition of buried bodies in traditional cemeteries releases\ud high amounts of heavy metals into the ground, which compromises population settlements near the cemeterial\ud areas. In each of the three selected cemeteries (A, B and C), five sampling points were determined through the\ud Triangular Irregular Network (TIN) method. The depths to collect the samples were 0-20cm and 20-40cm. Four\ud sample sites outside the cemeteries (for the same depths), 100m away from each other were also defined in order\ud to obtain a triangulation of up to 400m away from each analyzed cemetery. The results indicated that all\ud cemeteries in question had significantly higher heavy metal values when compared to Brazilian tolerated limits,\ud especially regarding to copper (Cu). Iron (Fe), manganese (Mn) and lead (Pb) concentration analysis also\ud deserve attention due to the high values found. The results of this research warn for possible soil contamination\ud hazards by heavy metals to residents who live near cemeteries, in a 400m radius
