Conclusion on classification

* Short term Toxicity to Fish: LC50-96h = 5.3 mg/L

Based on the results of this study, tetramethylthiuram monosulphide is considered as toxic to fish in accordance with International GHS.

 

* Short term toxicity to aquatic invertebrates: EC50-48h = 2.9 mg/L.

Based on the results of this study, tetramethylthiuram monosulphide is considered as toxic to aquatic invertebrates in accordance with International GHS.

 

* Toxicity to aquatic algae: EC50 -72h= 0.32 mg/L

According to EU regulation 1272/2008, tetramethylthiuram monosulphide is considered as very toxic for algae based on growth rate inhibition.

 

* Tetramethylthiuram monosulphide is not rapidly biodegradable according to the latter mentioned regulation (not readily biodegradable and not rapidly hydrolysable)

* Tetramethylthiuram monosulphide is not expected to bioaccumulate according to the latter mentioned regulation (log Kow < 4 and no experimental BCF)

According to CLP and the results obtained with acute and chronic tests mentioned above, tetramethylthiuram monosulphide should be classified aquatic acute I (H400, M factor =1) and aquatic chronic I (H410, M factor =10).
