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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Acetylene is expected to partition to the air from water, reducing the potential for exposure. Volatilisation for surface waters will predictably be rapid: calculation based on Henry's Law constant indicates that the volatisation half life will be <6 days in a water body up to10 metres deep (PEDERSEN et al 1995) and similar calculations using the EPISuite v.4.0 model predicts (USEPA 2009) half-lives of 32 minutes and 49 hours in rivers and lakes respectively (1m depth, wind velocity 5 and 0.5 m/sec respectively). If released into surface waters, volatilisation will therefore ensure rapid removal of acetylene into the atmospheric compartment.
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.
