Description of key information
There is no data available for the substance manganese glucoheptonate on toxicity towards aquatic organisms and microorganisms. However, there is data available for the read-across substances sodium gluconate, gluconic acid, manganese dichloride, manganese sulfate and elemental managanese. The values for these source substances were converted to the registered substance under consideration of the molecular weight and the purity. This data is used within a frame of a weight-of-evidence approach to assess the toxicity of manganese glucoheptonate. The values calculated for manganese glucoheptonate, which were used for hazard assessment are presented in the following.
Fish
LC50 (96h): 37.34 mg/L for Oncorhynchus mykiss (test item: MnCl2) (WHO, 2004).
Invertebrates
EC50 (48h): 64.4 mg/L for Daphnia magna (test item: MnSO4 * 4H2O) (Khangarot and Ray, 1989).
Algae
EC50(14d): 24.11 mg/L for Selenastrum capricornutum (test item: MnCl2 * 4H2O) (Christensen et al., 1979).
Microorganisms
IC/EC50 (9h): 1633.5 mg/L for Tetrahymena pyriformis (test item: MnSO4 * H2O) (Bogaerts et al., 1998)
Additional information
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.
