【 摘 要 】

Mercury distributionand geochemical support on the Continental Margin was evaluated at the CamposBasin, Rio de Janeiro state, Brazil. The average concentrations for all analyzedelements were, respectively, 20 ± 5 ng g-1 (Hg); 30 ±14 mg g-1 (Al); 16 ± 6 mg g-1 (Fe), and 254 ±83 µg g-1 (Mn). Silt and clay content, total carbonate and Hg,and organic carbon increased with depth. Finally, the relationship between Hgand silt clay showed significant positive correlation. Total Hg concentrationsare the background level described primarily (~40 ng g-1).
