title: Nematode test to estimate the hazard potential of solved contaminations.
abstract: The acute toxicity of lindane, pentachlorophenol and a fluortenside was examined using a recently developed ecotoxicity test with the terrestrial nematode species Panagrellus redivivus. The exposure was performed in aqueous solution over an investigation period of 96 h. For lindane a time dependent decrease of the survival rate (LC50 after 96 h: 0.4 mg/l) was observed which indicates a high cuticular permeability of the insecticide. For pentachlorophenol the LC50 (96 h) was 13 mg/l, for the fluortenside a value of 110 mg/l was determined.
