    Abstract

    The springtail Folsomia candida was exposed to the insecticide parathion in loamy, sandy and peaty soils. The dose-response relationships were measured and used to calculate the 50%-effect (EC50) values. The toxicity of parathion in the three soils could be explained from its bio-availability, as a result of adsorption and transformation. In soil, bio-availability decreased faster than pesticide content, due to continued shift to stronger adsorption. A first estimate of pesticide effect on soil organisms can be obtained by combining water-only toxicity values with measurements/calculations of the concentration in soil solution.
