Additional information

In a key study phosphonic acid was tested on the carp Cyprinus carpio according to OECD Guideline 203 and under GLP. The test was performed as a limit test with 100 mg/l. The test concentration was verified by analytical measurements. After 96 hours, no effects were found so the 96h-LC50 exceeds 100 mg/l (reliability 1).
