Additional information

Conclusion on classification

Data relevant for classification:

Aquatic acute toxicity

For fish:                             96 h, LC50(Oncorhynchus mykiss): >116 mg/L

For aquatic invertebrates:    48 h, EC50(Daphnia magna): > 100 mg/L

For algae/aquatic plants:     72 h, ErC50(Pseudokirchneriella subcapitata): 6.9 mg/L

 

Aquatic chronic toxicity

For fish:                             not available

For aquatic invertebrates:     not available

For algae/aquatic plants:     72 h, NOErC (Pseudokirchnerella subcapitata): 0.54 mg/L

Degradation

The substance is rapidely degradable via the biotic and abiotic route.

 

Conclusion:

The acute aquatic toxicity L(E)C50 values are > 1 mg/L for fish, aquatic invertebrates and algae. A chronic toxicity endpoint is available for algae (NOECs=0.54 mg/L). As tin bis(2 -ethylhexanoate) is rapidely degradable, the substance is classified and labelled as Category Chronic 3 according to Regulation (EC) No.1272/2008 (CLP) and the Regulation (EU) No. 286/2011 (2ndATP).
