Additional information
As reported in SIDS Dossier of MnO2 approved at SIAM 25 (17 -18 October 2007), Manganese dioxide is of low toxicity to aquatic organisms (fish, aquatic invertebrate and algae).This consideration comes from the following toxicity tests for manganese dioxide on aquatic organisms:
Acute toxicity:
Oryzias latipes: 96-hour LC50: no effects at saturation, (100 mg/l,nominal concentration)
Daphnia magna: 48-hour EC50: no effects at saturation, (100 mg/l,nominal concentration)
Pseudokirchneriella subcapitat:72-h ErC50, 72-h EbC50: no effects at saturation(100 mg/l,nominal concentration)
In SIDS Dossier of MnO2 approved at SIAM 25 (17 -18 October 2007) a study of 20 weeks about growth rate rainbow trout is also reported (Satoh et all, Availability to Carp of Manganese in White Fish Meal and of Various Manganese Compounds, Bull.Jpn.Soc.Sci.Fish.-Nippon Suisan Gakkaishi- 53(5):825-832, 1987): the highest rate of dwarfism was obtained in the fish receiving No-Manganese diet and a major growth is achieved from diet supplemented by Manganese salts. The major effects were observed with MnSO4 and MnCl2 and only light effects came from the use of MnO2 and MnCO3. Only effect are recorded for soluble salts. MnO2 is insoluble.
According to CLP Regulation (EC n. 1272/2008), the substance is not classified as hazardous to the aquatic environment.
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.
