Hazard assessment of chemicals in soil : Proposed ecotoxicological test strategy.
Based on a stepwise (tiered) approach, degradation, adsorption and leaching tests as well as various effect tests (using plants, microorganisms and animals) are recommended for the testing of environmental chemicals. If, after the tests of tiers 1 and 2, the results of a monospecies-effect-test (including a safety factor) are within the range of the predicted exposure, the ecotoxicological hazard should be determined using a terrestrial model ecosystem. Some of the tests for the proposed strategy were selected from practical experience in testing environmental chemicals in the laboratory, and some on the basis of a comprehensive literature review.
