| Abstract: | Purpose This paper evaluates the feasibility of using the buffering capacity of natural soil for the remediation of dredged material
before being disposed in soil landfills. To achieve that, an Integrated Soil Microcosms (ISM) system was designed to produce
elutriates and leachates from the sediment/soil percentage mixtures. Furthermore, to investigate the biological effects of
the contaminated sediments, the toxicity behavior of leachates and elutriates was assessed and compared by performing acute
(48 h) toxicity assays with the cladoceran Daphnia magna as test organism. |
