Resumen
This study was aimed at determining the range and spatial distribution of mercury in a geographical area influenced by the emissions of phosphate fertilizers industries in Rio Grande, Brazil. The case study demonstrated that mercury concentrations in a fine fraction of the surface soil close to the fertilizer factory reached levels as high as 800 μg kg -1. Increased mercury concentrations were detected up to 60 cm below the soil surface. Further, a significant impact of the elevated mercury levels was manifested in a 1-km zone around the factory. Technical grade sulfuric acid employed in superphosphate production is considered the principal source of this mercury contamination.
