Part of the Residue Reviews book series (RECT, volume 86)


High quality data describing changes in the biotic compartments of soils are indispensable prerequisites for ecotoxicological characterization of chemicals. Numerous results from careful experimental work are now available. The wealth of data, however, contributes only partially to our understanding and capability of hazard assessment. Frequently we experience a kind of helplessness on how to weight, rate, and evaluate data and ignore the urgent need for interpretation in sensible ecological terms.
