Conclusion on classification
Acute toxicity:
Based on the results obtained in aquatic toxicity studies, MTHPA was not classified and labelled according to Directive 67/548/EEC (DSD) and Annex VI of Regulation 1272/2008/EC (CLP).
Chronic toxicity:
Based on the results obtained in long-term aquatic toxicity studies, MTHPA was not classified and labelled according to Directive 67/548/EEC (DSD) and Annex VI of Regulation 1272/2008/EC (CLP).
Overview of Results used for Classification and Labelling:
Fish, short-term, freshwater: LC50 (96 h)> 100 mg/L (Anonymous, 1997)
Fish, long-term, freshwater: NOEC(14 d) = 100 mg/L (Anonymous, 1997)
Daphnia magna, short-term, freshwater: LC50 (48 h) = 130 mg/L (Anonymous, 1997)
Algae, freshwater: LC50 (72 h) = 68 mg/L (Anonymous, 1997)
