【 摘 要 】

Total Hg contentin soils of Baixada Santista, affected by different sources of pollution, andCardoso Island, which is almost free of anthropogenic activities, were determinedby CVAAS. To explain the fate of Hg in the ecosystem, pH, Eh, AVS, Stotaland Total Organic Carbon were also obtained throughout the soil profiles. Withthe exception of two sampling sites the average content of Hg in samples obtainedfor Baixada Santista was 0.34 ± 0.20 mg kg-1, which was closeto the average data at Cardoso Island (0.30 ± 0.21 mg kg-1).Both of them were below the limit established by CETESB - 0.50 mg kg-1.
