Additional information

Inhibitory effects of DOPA-Glycinate on microbial activity were tested by the activated sludge respiration inhibition test, following OECD guideline 209.No deviations from the guideline were reported.

The test substance is not known to exhibit any properties that could have affected the outcome of the test. The substance was tested at concentrations of 5.0, 12.5, 32, 80, 200 and 500 mg/L using activated sludge as inoculum.

The 3 h EC50 was determined to be 22 mg/L.
