The purpose of this study was to evaluate the acute toxicity of the test
substance to earthworm by observing the mortality and pathological
The artificial test involves keeping earthworms in samples of precisely
defined artificial soil to which a limit of concentration (1000 mg/kg)
of the test substance has been applied. Mortality is assessed 7 and 14
days after application, and then the acute toxicity of the test
substance is determined by the results of the mortality.
The results demonstrated the mortality in the controls, solvent and test
group was 0%, which fulfilled the validity criteria of not exceeding
10%. The mean moisture content of the control group and treatment
group’s artificial soil at the start and at the end of the test were
30.3% and 26.3% respectively.
Under the present test conditions, results indicated that the 14 Day
LC50 of the test substance to earthworms by artificial soil test was
greater than 1000 mg/kg dry soil.
The study was conducted to GLP in accordance with the OECD 207 guideline.
The results demonstrated the mortality in the controls solvent and test
group was 0%, which fulfilled the valid criteria of not exceeding 10%.
