Conclusion on classification
The most sensitive species for acute aquatic toxicity is fish, and an LC50 of 0.0349 mg/L was found (EC50 daphnia was 0.47 mg/L and for algae was > 1.36 mg/L). Based on these data, the substance is subject to classification as Acute Aquatic Category 1, H400 with an M-factor of 10, according to CLP (Regulation EC No. 1272/2008). Furthermore, chronic toxicity data are available for algae, fish, and daphnia and the lowest NOAEC found is for daphnia reproduction (4.26 µg/L), which in combination with the fact that the substance is not readily biodegradable results in an Aquatic Chronic Category 1 classification, H410 with an M-factor of 10 according to CLP.
According to RAC Decision adopted on 16 September 2016, based on the lowest acute toxicity observed in a study not available at Endura, Tetramethrin is classified as: Aquatic Acute 1 (H400) with an acute M-factor of 100, Aquatic Chronic 1 (H410) with a chronic M-factor of 100.
Although d-Tetramethrin (CAS nr.548460-64-6) is not specifically discussed in the RAC Decision adopted on 16 September 2016, it is considered appropriate reading-across the same M-factors to d-Tetramethrin.
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).
