Additional information
No data are available with the registered substance, however reliable data are available with the parent substance EDTMP acid (CAS 1429-50-1). A 14 d and 96 h LC50 value of 250 mg active acid/l and a NOEC value of 114 mg/l have been determined for the effects of EDTMP acid on the mortality of the freshwater fish O. mykiss based on mean measured concentrations.
A 96 h LC50 value of 8000 µl/l (ppm), equivalent to 1600 mg active acid/L has been reported for the effects of EDTMP acid on the mortality of the marine fish C. variegatus.
