Description of key information

The two key Tadokoro studies appear to be of similar quality. They provide 96h EC50 values of 4,300mg/l and 3,230mg/l for freshwater and marine water algae species respectively.

Key value for chemical safety assessment

EC50 for freshwater algae:
4 300 mg/L
EC50 for marine water algae:
3 230 mg/L

Additional information

The results indicate that TDI has low toxicity to freshwater and marine algae. As an indication of any potential indirect hazard due to TDA formation, the 72h EC50 (growth rate) for TDA vs Scenedesmus subspicatus was 126 mg/l.
