- Executive summary:
The acute toxicity of the test substance to earthworms, Eisenia fetida, was estimated in a 14-day soil exposure laboratory study conducted under OECD Guideline 207 in artificial soil. Based on the results of a range-finding test, a limit test was conducted. The 14-day LC50 and NOEC were determined to be greater than 1000 mg/kg dry weight soil.
