Additional information
Based on the available data for the aquatic compartment SAS is most toxic to daphnia with an acute EC50 (48h) of 9.2 mg/L (a.i.) and a chronic NOEC reproduction (21d) of 0.04 mg/ (a.i.).
Based on the available data for the freshwater sediment compartment SAS has a NOEC reproduction nematode (4d) of 939 mg/kg dw.(a.i.).
Based on the available data for the terrestrial compartment SAS is most toxic to earthworms with a Chronic NOEC (56d, reproduction) of 470 mg/kg soil dw.(a.i.).
Conclusion on classification
The Environmental classification for SAS has to take into account the lowest acute value for aquatic species which is the Fish LC50 (96h) of 5.5 mg/L a.i. (see Section 6.1.1). For CLP classification also the lowest chronic value for aquatic species which is the Daphnia NOEC 21d reproduction of 0.4 mg/l (see section 6.1.4) has to be considered.
In addition SAS is readily biodegradable (see Section 5.2.1) and due to the low octanol water partitioning coefficient of 0.2 (see Section 4.7) bioaccumulation can be neglected.
Classification according DSD 67/548/EEC:
Short-term effects: No classification required
as 3 acute ecotoxicity values are available >1 mg/l
Long-term effect: No classification required
as 3 acute ecotoxicity values are available >1 mg/l, the substance is readily biodegradable and has a low bioaccumulation potential (log Kow 0.2)
Classification according to 2nd ATP CLP 2011/286/EU for Environment
Short-term effects: No classification required
as 3 acute ecotoxicity values are available >1 mg/l
Long-term effect: Category Chronic 3, H412
as 3 chronic ecotoxicity values are available with the lowest value (Daphnia NOEC 21d reproduction 0.4 mg/l) > 0.1 mg/l & <= 1 mg/l and the substance is readily biodegradable
