Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
As 1,1,1-trichloroethane has no specific herbicide or activity testing on higher aquatic plants is not required. The literature contains no information on the studies conducted in this area therefore it is presumed to address this data requirement by waiver as the risk of exposure is low.
Key value for chemical safety assessment
Additional information
The distribution model used in the Euro Chlor review indicates that there is very little deposition to the aquatic environment and virtually none to the terrestrial environment. This summary of existing data and the risk assessment conducted by De Rooij et al 2004 concluded that the biological action of 1,1,1-trichloroethane can be classified as basic rather than specific. As 1,1,1-trichloroethane has not been shown to have herbicidal properties and the PEC/PNEC ratios for algae are sufficiently high current European guidance relating to other directives such as 91/414 would indicate that additional testing on aquatic higher plants is not required
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.
