Abstract

Phenanthrene toxicity in soil is related to its bioaccessibility and bioavailability. The Dissolved Organic Matter (DOM) can increase the mobility of a contaminant, and should increase its bioavailability and, consequently, its toxicity. The aging should decrease the soil bioavailability ofpollutants. This research aims at investigating the influence of the DOM on the bioaccessibility, bioavailability and toxicity of PRE. Agricultural soil samples were spiked with 15 and 150 ppm of pollutant, aged at 20 and 120 days and treated with DOM extracted from compost. The bioaccessibility ofPHE in presence ofDOM was lower than that observed in absence ofDOM. The bioavailability measured through PRE uptake in Eisenia andrei exposed for 14 days to soil samples treated with DOM was lower than that observed in absence of DOM. The DOM seemed to positively interact with earthworms because their survival was higher in samples polluted and treated with DOM than in those polluted but untreated with DOM.
