Description of key information
Additional information
Aquatic toxicity: freshwater, short-term
The table below presents an overview of the reliable acute aquatic toxicity data available for the hazard assessment of Nickel iron chromite black spinel. Concentrations are based on water accomodated fractions (WAF).
Pseudokirchneriella subcapitata |
growth rate |
72-h EL50 |
> 100 mg/L (WAF) |
Wenzel, 2014 |
Daphnia magna |
mortality |
48-h EL50 |
> 320 mg/L (WAF) |
Schlich, 2014 |
Brachydanio rerio |
mortality |
96-h LC50 |
> 100 mg/L (WAF) |
Teigeler, 2014 |
Invertebrates:The acute toxicity to Daphnia magna was determined according to OECD Guideline 202 (Schlich, 2014). Daphnids did not become immobilized during the test period of 48 h at tested concentrations up to 320 mg/L (water accommodated fraction-WAF, 7 days); the respective 48-h EC50 is >= 320 mg/L (WAF).
Fish:Information on acute fish toxicity is available from a study performed according to OECD Guideline 203. Fish (Danio rerio) were exposed for 96 hours to water accommodated fractions (7 days) up to 100 mg/L under static conditions. At all tested loadings, neither behavioral abnormalities nor mortality occurred.
Algae:The toxic effects of the water accommodated fractions ofNickel iron chromite black spinelon the growth rate of algae (Pseudokirchneriella subcapitata) were studied in a state-of-the-art test according to OECD Guideline 201 (Wenzel, 2014). The EL50 value for the 72-h inhibition of growth rate of P. subcapitata (water accommodated fraction-WAF, 7 days) is >= 100 mg/L (WAF).
Aquatic toxicity: freshwater, long-term
The table below presents an overview of the reliable long-term aquatic toxicity data available for the hazard assessment ofNickel iron chromite black spinel. Concentrations are based on water accomodated fractions.
Pseudokirchneriella subcapitata |
growth rate |
72-h EL10 |
> 100 mg/L (WAF) |
Wenzel, 2014 |
Chronic toxicity data ofNickel iron chromite black spinelare available for algae. The long-term toxic effects of the Water Accommodated Fractions (WAF) ofNickel iron chromite black spinelon the growth rate of algae (Pseudokirchneriella subcapitata) were studied in a state-of-the-art test according to OECD Guideline 201 (Wenzel, 2014). The EL10 value for the 72-h inhibition of growth rate of P. subcapitata is > 100 mg/L (WAF).
Acute aquatic toxicity data at three trophic levels (algae, daphnia, fish) and from standard toxicity tests indicate a lack of an acute toxic potential of Nickel iron chromite black spinelin the aquatic environment, i.e. all EL50 values are above 100 mg/L. Chronic toxicity data for algae indicate a lack of a toxicity potential of Nickel iron chromite black spinelin the aquatic environment long-term for this trophic level which may be explained at least in parts with the insolubility of the pigment.
Thus, based on available short-term and long-term aquatic toxicity data, classification and labelling for aquatic toxicity is not required in accordance with Directive 67/548 EEC and CLP Regulation (EC) No 1272/2008 (Table 4.1.0 (b) (iii)).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
