Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The distribution model predicts that concentrations in soil and sediments will be extremely low (<0.01% of total releases to the environment). Toxicity to aerobic and anaerobic bacteria has already been addressed in previous summaries and it is evident that under the correct conditions bacteria are capable of degrading 1,1,1-trichloroethane by a number of different routes. Studies on the effects on macroorganisms are limited to earthworm which is not sensitive to 1,1,1-trichloroethane. Similarly protozoa also appear to be relatively insensitive.
In view of the very low levels expected to reach this environmental compartment the opinion of experts in this area is that this compartment can be discounted for risk assessment purposes. The applicant supports this view.
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.
