The acute toxicity, 50% lethal concentration (LC(50)), to the earthworm Eisenia foetida of two chloroanilines was determined by the EEC (1985) method. The test was made on artificial and natural soils. The acute toxicity measured by an (LX(50)) for 2,4,5-trichloroaniline varied between 460 and 3100 mg/kg and for 2,3,5-6-tetrachloroaniline between 1400 and 2000 mg/kg. In order to assess the toxicity of chloroanilines to the earthworms in soil, LX(50) (mmol/kg) was corrleated wth the organic carbon content f(oc), and the octanol/water partition coefficient (K(ow)) in a multiple linear regression analysis: LX(50) = 4.3f(oc) (0.9)K(ow) (0.1).
