MODELING ZINC TOXICITY FOR TERRESTRIAL INVERTEBRATES

摘要

Acute and chronic ecotoxicity tests with zinc were performed with the earthworm Eisenia fetida, the potworn Enchy- traeus albidus, and the springtail Folsomia candida. To assess the influence of the soil type on zinc toxicity for these soil invertebrates, these tests were carried out in a standard artificial soil, a sandy a loamy field soil. Based on the results of this experimental work and data taken from literature, models were developed relating the ecotoxicity of zinc to the most important parameters controlling bioavailability: pH and cation exchanges capacity.
