Additional information

A study regarding long-term toxicity to aquatic invertebrates is reported in database ECOTOX, EPA for Sulfadimidine CAS 57-68-1 with reference to De Liguoro, Chemosphere75(11): 1519-1524,2008: NOEC Daphnia magna 21days = 1.563 mg/l

Based on this data of long-term toxicity to aquatic invertebrates (NOEL = 1.563 mg/l) and considering that the substance is predicted not ready biodegradable, no classification for chronic aquatic toxicity is proposed for Sulfadimidine.
