Description of key information
For the endpoints Short-term toxicity to aquatic invertebrates and Toxicity to algae and cyanobacteria read across to the analogue substance guanidinium phosphate (1:1) was performed. The relevant (no)effect values were calculated for the target substance bisguanidinium phosphate (2:1) under consideration of the higher guanidinium content. The obtained values were as follows:
- OECD 202, D. magna, GLP, EC50 (48 h) > 68.81
- OECD 201, GLP, P. subcapitata, EC50 (72 h) = 75.69 mg/L, EC10 (72 h) = 11.01 mg/L, NOEC = 6.88 mg/L
Based on these values for bisguanidinium phosphate on acute aquatic toxicity and taken into account that the test item is not readily biodegradable, the substance is classified as Aquatic Chronic Category 3 (H412) according to Regulation (EC) no 1272/2008.
