Conclusion on classification

The environmental classification of T002907 is currently not harmonized according to the CLP Regulation (EC) 1272/2008. All three studies showed no toxicity up to the highest nominal concentration tested being 100 mg/L. The substance did not show toxic effects to fish, aquatic invertebrates at its saturation level in the respective test medium. Classification should only be based on toxic responses observed in the soluble range, therefore the substance is not expected to be chronically toxic to aquatic organisms either based on the results of the algae study (NOEC >= 87 mg/L). Based on the available acute data, the substance should not be classified for acute toxicity following Annex I, table 4.1.0 b (iii) of the CLP regulation (there are no acute values ≤ 1 mg/L).

In the algal growth inhibition study, the ErC10 and NOErC for algae were > 100 mg/L (> 87 mg/L measured concentration). No other long-term values are available, therefore the substance should not be classified for chronic toxicity based on the acute toxicity values, following Annex I, table 4.1.0 b (iii) of the CLP Regulation. No labeling is required.
