Additional information
Tetraphosphorus trisulphide is non-toxic to aquatic species at three trophic levels: fish, aquatic invertebrates and algae, as demonstrated by the results below.
- LC50 96h Danio Rerio > 100 mg/l loading rate: experimental data obtained testing the substance according to OECD TG 203.
- EC50 48h Daphnia Magna > 100 mg/l loading rate: experimental data obtained testing the substance according to OECD TG 202.
- ErC50 72h Desmodesmus subspicatus > 100 mg/l (loading rate): experimental data obtained testing the substance according to OECD TG 201.
Moreover, the substance was tested for activated sludge respiration inhibition according to OECD TG 209 and EC50 3h activated sludge = 471 mg/l (loading rate)and NOEC = 31.6 mg/l (loading rate) were the results of this test.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
