Description of key information
The key study (Bayer AG, 1984) carried out according to a method similar to OECD Guideline 203 on Danio rerio gave a 96h LC50 value of 20mg/L.
Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Effect concentration:
- 20 mg/L
Marine water fish
Marine water fish
- Effect concentration:
- 0.414 mg/L
Additional information
A study with Danio rerio gave a 96h LC50value of 20 mg/L
Acute Toxicity on Saltwater Fish
Pagrus major: 96h-LC50 =0.414 mg/L (flow-through, measured concentration of 2,4 -TDA).
Conclusion
Pagrus major was the most sensitive to TDA. The 96h-LC50 values from the study with reliability (1) being more than a factor of 1000 lower than the 96h-LC50 values for other fish species.
