Additional information
The acute aquatic studies for S-205 give results greater than the water solubility. This is cause for concern and indicates that it might be classified as Aquatic Chronic 4. However the long-term NOEC > water solubility, 21d Daphnia NOEC is 100 mg/l. This confirms that over extended periods S-205 is not toxic in the aquatic compartment.
Conclusion on classification
As determined by the argument above, S-205 is not classified for environmental toxicity.
