Concentrações de metais em solo ocupado por cemitério - uso da técnica de espectrometria de fluorescência de raios-x por energia dispersiva - EDXRF Concentrations of metals in soil for busy cemetery - use the technique of ray fluorescence spectrometry-energy dispersive x - EDXRF

The study of contamination of soil and surface water resources and / or by underground cemeteries is an area still fresh in the scientific community. The main contaminant is necrochorume generated from the decomposition process of the human body over a period of time. This study aimed to determine the range of variation of the concentration of some metals in soil profiles. We used the technique of Fluorescence Spectroscopy Energy Dispersive X-ray (EDXRF) evaluated in 70 soil samples. The study area was a cemetery located in Seberi in the northwest of the State of Rio Grande do Sul, Parana Basin, in Oxisols red ferric aluminum originated from the weathering of volcanic rocks, basalts forming the type of the Serra Geral Aquifer System / SGAS. The selection of the sampling sites was estimated from the preferential flow of surface water, using the mathematical method of kriging interpolation. We considered 10 collection points distributed between the ground surface to a depth of 300 cm, in materials with stony clay matrix to the C horizon Metals Aluminium and Iron and Vanadium nonmetal showed varying concentrations in different depths of the soil profile.
