Description of key information
In tests carried out with an 80/20 mixture of 2,4- and 2,6-TDA, and according to OECD guideline 208, a 14 d EC50 of 320 mg/kg soil (dry weight) was obtained. This value may be used to derive a PNECsoil.
Key value for chemical safety assessment
Additional information
Available data on toxicity to terrestrial plants
Two experimental studies of reliability (2) were recorded for this endpoint.
Main results on toxicity to terrestrial plants
All experimental studies were short-term and performed according to OECD guideline 208 on two differents plant species. The lowest EC50 from the results of these two tests are reported below:
Avena sativa: EC50-14d=320 -1000 mg/kg soil dry weight (nominal concentrations of TDA80/20)
Lactuca sativa:EC50-14d=320 -1000 mg/kg soil dry weight (nominal concentrations of TDA80/20)
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
