An acute-toxicty test is described in which the springtail Folsomia candida was exposed to pesticides in water for four days. The test method has been designed for the direct and economical chemical analyses of all the concentrations during the execution of the test. The 96-hour EC50 values determined for parathion, carbofuran, dimethoate and oxamyl were 0.0087, 0.222, 16.2 and 23.6 mg/l, respectively. The toxicity of the pesticides was correlated with their lipophilicity. For terrestrial hazard assessment procedures the use of the intrinsic toxicity of chemicals to soil organisms, as determined in this simple test, is proposed.
