Description of key information

The 72h toxicity against Desmodesmus subspicatus is ErC50 and EyC50 > 100 mg/L , corresponding to >27.7 mg/L (active ingredients) as well as ErC10 and EyC10.The 72h NOEC based on growth rate as well as  yield is ≥ 100 mg/L, corresponding to ≥27.7 mg/L (active ingredients) .

Key value for chemical safety assessment

EC50 for freshwater algae:
100 mg/L
EC10 or NOEC for freshwater algae:
100 mg/L

Additional information

The substance is only imported and used as aqueous solution. There are no concentration steps in the use pattern of the aqueous solution of the substance. So the chemical safety assessment is based on the effect concentration of Reaction mass of 1,3-benzene disulfonic acid andsulfuric acid, aqueous solution.
