Abstract

Bioavailability, toxicity, persistence and accumulation of arsenic and mercury in living organisms are strongly influenced by chemical speciation. This study was realized to test two innovative techniques, HPLC-ICP-MS, which allows the chemical speciation, and DGT, which measures lability in soil solution and soil resupply, in the evaluation of risk from contaminated soil. The presence of arsenic and mercury in the examined soil is considerable, but speciation and DGT analysis suggest that availability of these trace elements is low. Modification of mobility and availability to living organisms induced by plant cultivation, fertilization and mycorrhiza inoculation both in soil and solution were also investigated. HPLC-ICP-MS and DGT techniques were confirmed as complementary in the assessment of the risk from contaminated soil.
