Additional information
Short term aquatic toxicity
Fish
Key Study:
In an OECD 203 study, according to GLP, the 96 hour toxicity (LC50) of exposure of fathead minnow (Pimephales promelas) to the test item resulted in an LC50 value of greater than 100% v/v saturated solution, based on the nominal test concentration. The No Observed Effect Concentration (NOEC) was 100% v/v saturated solution (Envigo Research Limited, Ltd, 2018).
Invertebrates
Key Study:
In an OECD 202 study, conducted according to GLP, the acute toxicity of the test item to the freshwater invertebrate Daphnia magna was investigated and based on the geometric mean measured test concentrations gave a 48-Hour EC50 value of greater than 0.0076 mg/L as zinc (equivalent to 0.071 mg/L as test item). The No Observed Effect Concentration was 0.0076 mg/L as zinc (equivalent to 0.071 mg/L as test item) mg/L. This study showed that there were no toxic effects at saturation (Envigo Research Limited, Ltd, 2018).
Algae
Key Study:
In an OECD 201 study, conducted according to GLP, the effect of the test item on the growth of Pseudokirchneriella subcapitata was investigated and the 72 hour EC50 value based on growth rate was determined to be greater than 100% v/v saturated solution, the NOEC was given as 12.5% v/v saturated solution and the LOEC determined to be 25% v/v saturated solution (Envigo Research Limited, Ltd, 2018).
Micro-organisms
Key Study:
In an OECD 209 study, conducted according to GLP, No effects of the test item were observed on the respiration of activated sewage sludge following a 3-hour exposure, resulting in an EC50 value of greater than 1000 mg/L. The No Observed Effect Concentration (NOEC) following the 3-hour exposure was 1000 mg/L (Envigo Research Limited, Ltd, 2018).
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.
