Abstract
This study presents preliminary results on mercury distribution releas ed by gold mining activities, in soils from Vila Nova River region, an area located in Sew do Navio, Amapa in the Brazilian Amazon. The soil samples were separated in two grain sizes, sand (between 2 and 0.063 mm) and silt+clay (<63 mu m), and have been analysed by radiochemical neutron activation analysis. The precision and accuracy of the method were verified by means of the reference material analysis GXR-5 (USGS) .
