An activated sludge respiration inhibition test was conducted according to GLP and OECD Guideline 209 on the chemical NaDMH. Based on the results of a range-finding test a 'limit' test was conducted at nominal concentrations of 1.0, 10, 100 and 1000 mg/L. The 3-hour EC50 was 2200 mg/L and NOEC = 320 mg/L. An activated sludge respiration inhibition test was conducted according to GLP and OECD Guideline 209 on the analogue chemical DMH, the results of which are included here for supporting read-across purposes. Based on the results of a range-finding test a 'limit' test was conducted at a nominal concentration of 1000 mg/L. The 3 hour EC50 was > 1000 mg/L and NOEC = 1000 mg/L
As previously stated one of these studies
has been performed on DMH (Dimethyl Hydantoin) and has been used for
read-across purposes. A summary of data for read-across of NaDMH with
DMH is given in Section 13.
