Resumo
RMB will be a nuclear reactor for research and production of radioisotopes. Its applications extend to agriculture, industry and the environment. With the changes that will occur in the study area by its construction, the flow of vehicles will increase. It is known that one of the largest anthropogenic sources of PAHs is from the burning of fossil fuels and biomass. The aim of this research was to identify and quantify 14 of the 16 majorities PAHs in the sediment samples at RMB installations area in a period before the enterprise construction, June 2017, using the methodology developed and validated by Brito, 2009. It was observed individual concentrations from 0.05 to 1.11 μg g-1 in this first evaluation indicating that, although were found some PAHs concentrations above the established values by CONAMA and CETESB, this area still remains preserved. Pyrene was the compound that had the highest concentrations at different collecting points (1.11±0.03 and 1.09±0.02 μg g-1). Although were observed some PAHs concentrations above the established values by CONAMA and CETESB, the area is preserved. The study will provide previous information on PAHs concentrations in the area of the enterprise, providing information for the environmental impact study after the construction of the enterprise.
