Description of key information
Additional information
No ecotoxicity test results are available for Reaction mass of (Gluconate)3Fe-Na3 and NaCl (acute daphnia test is running). For this reason the available studies from the structurally similar substance Sodium glucoheptonate (CAS no 31138 -65 -5) have been read across to the Reaction mass of (Gluconate)3Fe-Na3 and NaCl.
For Sodium glucoheptonate (CAS no 31138 -65 -5) short term aquatic toxicity studies have been conducted for three trophic levels according to GLP and OECD guidelines. The Key studies have been conducted on Oncorhynchus mykiss (rainbow trout), Daphnia magna (water flea) and Pseudokirchneriella subcapitata (green algae).
The results of the three short term aquatic tox studies were as follows:
Fish LC50 = > 1000 mg/L Fish NOEC = 1000 mg/L
Daphnia EC50 = > 1000 mg/L Daphnia NOEC = 1000 mg/L
Algae EC50 = 790 mg/L Algae NOEC = 100 mg/L
An Activated Sludge Respiration Inhibition (ASRI) study was also conducted on the test material, the EC50 value was greater than 1000 mg/L and the NOEC was determined to be 1000 mg/L as no effects were observed within the study. Due to this the ASRI study is not classified.
From the results of these three studies it can be seen that the algae is the most sensitive species to the test material. The algae study produced the lowest EC50 value out of all three aquatic toxicity studies, and all three studies were tested up to the same concentration level (1000 mg/L). The results of this study were not sufficient to warrant classification as the test material is readily biodegradable in water. Therefore the test material sodium glucoheptonate has not been classified as hazardous to the environment.
Based on the available acute data as well as based on the QSAR analysis of the substance (section 13 IUCLID) together with the SIDS (2004) of sodium gluconate (Cas no. 527-07-1; read across from a structurally very similar substance), it can be concluded that it is extremely unlikely that Reaction mass of (Gluconate)3Fe-Na3 and NaCl will raise any concern for aquatic organisms.
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).
