ECOTOXICITY MONITORING OF HYDROCARBON-CONTAMINATED SOIL USING EARTHWORM(EISENIA FOETIDA)

摘要

In order to assess the applicability of an earthworm bioassay as a technique for monitoring the soil flushing process, short-term and long-term toxicity tests were conducted on remediated soil using various pore volumes of surfactant solution. Results obtained on short-term toxicity testing indicated that biomass increased as the soil flushing proceeded, and on diesel-contaminated soils this testing showed that the effect of diesel is lethal and that 25 pore volumes of soil surfactant were not sufficient to abrogate the toxic effect of diese.
