Description of key information
Additional information
One short-term data is available for each of the trophic level in the aquatic compartment:
Fish
LC50-96 h was estimated using measured concentrations as being equal to 3.68 mg/L.
Aquatic invertebrates
The results of the 48 hour static Daphnia magna toxicity study was estimated at 4.5 (3.0-6.8) mg/1.
Algae
The 72h-EC50 of DTDM was estimated at 35 mg/l.
As a consequence and based on these values DTDM can be considered as toxic to the aquatic life.
According to the claimed used of DTDM, exposure of the aquatic compartment is likely. However, the risk assessment demonstrated that there is no risk for aquatic organisms using the PNEC derived based upon acute data. Therefore, further long-term testing on aquatic organisms is not needed.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
