Description of key information
Two limit tests and one actual determined LC50 value are available. The actual determined concrete LC50 value is used as key value and expressed as DTPA-FeNa2 amounts to 1085 mg/L.

Additional information
Three acute freshwater fish studies were assessed for this endpoint. One study was conducted with rainbow trout (Oncorhynchus mykiss) exposed to the pentapotassium salt of DTPA, while the other study was conducted with bluegill sunfish (Lepomis machrochirus) exposed to the pentasodium salt of DTPA. A third study with DTPA-FeHNa confirmed the low toxicity to zebra fish (Danio rerio).
All studies were found to be of good quality and were comparable to or equivalent to guideline studies. The acute tests with the rainbow trout and zebra fish were limit tests that concluded that the 96 hour LC50 for DTPA-K5 and DTPA-FeHNa was >1000 mg/L and > 100 mg/L respectively.
The acute test with the bluegill sunfish concluded that the 96-hour LC50 for pentasodium DTPA was 1115 mg/L, which is equivalent to 1085 mg/L DTPA-FeNa2 following stoichiometric conversion.Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
