CAS number: -
In an acute toxicity test, performed according to "Guideline HJ/T 153
-2004" and "Guidelines for the Testing of Chemicals-Effects on Biotic
Systems", with reference to OECD guideline 207, and according to GLP
principles,Eisenia fetida(earthworm) were exposed to a limit
concentration (1000 mg/kg (dry soil)) of the test substance for 14 days.
A blank control group was included. The treatment group and the control
groups consisted of 4 replicates of 10 worms each. The test was
performed in artificial soil consisting of sphagnum peat (10%), kaolin
clay (20%) and quartz sand (70%). Based on the results of a range
finding study in which no mortality occurred in all tested
concentrations (10, 500 and 1000 mg/kg dry soil), a nominal
concentration of 1000 mg/kg dry soil was used in the limit test.
Mortality was recorded at day 7 and at day 14. No mortality occurred in
the blank control group and in the treatment group. The LC50 was
determined to be >1000 mg/kg (dry soil), based on the nominal test
concentration. The test is considered reliable without restriction.
14d-LC50 > 1000 mg/kg, no acute hazard identified.
