Additional information

Valid aquatic short-term toxicity studies with algae (OECD TG 201), Daphnia (OECD TG 202), and fish (OECD TG 203) were being conducted with the test material. For algal growth rate and the Daphnia the EC50 values are > 100 mg/L. For algae biomass an EC50 of 48 mg/L was determined. The limit test for fish therefore was conducted at 48 mg/L, which revealed no effects. The most sensitive of the three trophic levels therefore is the algae with an EC50 (biomass) of 48 mg/L. In a worst case approach this value was used as basis for the computation of PNECs.

In a valid sludge respiration inhibition study (OECD TG 209), the effect of the test item on the respiration of activated sewage sludge micro-organisms gave a 3-Hour EC10 value of greater than 1000 mg ai/L. The No Observed Effect Concentration (NOEC) after 3 hours exposure was 100 mg ai/L, which was used for the computation of the PNEC STP.

No studies available for sediment and soil toxicity. The equilibrium-partitioning method is applicable for the computation of PNEC sediment and PNEC soil.

Conclusion on classification

Acute aquatic toxicity:

No classification applicable, as all L(E)C50 values from aquatic short term toxicity studies revealed results well above the classification trigger value of 1.0 mg/L.

Chronic aquatic toxicity:

The algal growth inhibition study is the only available long-term study on aquatic toxicity. The study revealed (for growth rate) a 72h-NOEC value of 6.25 mg/L. Based on this NOEC, which is above the classification trigger value of 1.0 mg/L, there results no classification for chronic aquatic toxicity. The L(E)C50 values for fish and Daphnia are above 48 mg/L 100 mg/L, respectively, and thus also cannot trigger chronic aquatic toxicity classification.
