Additional information

Toxicity to fish

The LC50 of fish is >4.5 mg/L.

Toxicity to aquatic invertebrates

The EC50 of Daphnia magna is > 5.25 mg/L.

Toxicity to algae

The effect of the test item on the growth of Pseudokirchneriella subcapitata has been investigated and gave EC50 values of greater than 100% v/v saturated solution. The No Observed Effect Concentration was 100% v/v saturated solution. This study showed that there were no toxic effects at saturation. As the water solubility of the test item to be 0.007 mg/L, we regard the NOEC value is > 0.007 mg/L.

Toxicity to micro-organisms

The effect of the test material on the respiration of activated sewage sludge micro-organisms gave a 3-Hour EC50 of Greater than 1000 mg/L. The No Observed Effect Concentration (NOEC) after 3 hours exposure was 1000 mg/L.
