1 000 mg/kg soil dw

Additional information

The effect of DOPA-Glycinate (20% a.i., as manufactured) on survival of adult earthworms of the species Eisenia fetida was investigated according to OECD Guideline 207 and EC method C.8. The worms were placed in a defined artificial soil substrate containing the test item in nominal concentrations of 1.64, 4.1, 10.24, 25.6, 64, 160, 400, and 1000 mg active substance per kg dry soil. The test item was incorporated into the test soil at the beginning of the experiment, and the effects on biomass and mortality were determined after 14 days.

There was no mortality, neither in the controls nor at any test concentration up to the limit test concentration of 1000 mg a.i./kg dry soil. There was no statistically significant influence of DOPA-Glycinate on body weight change up to the limit test concentration of 1000 mg a.i./kg dry soil.

The LC50 for the tested species was found to be >/= 1000 mg a.i./kg dry soil.
