Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

DMS photolytic turnover rate in Pacific Ocean surface mixed layer (0-60 m) ranges from 0.05 to 0.15 day -1. The photolysis of DMS followed pseudo-first order kinetics at concentrations less than 50 +/- 15 nM. In laboratory esperiments, the photolysis of 20 nM DMS (in Pacific Ocean seawater) was followed to 75 % completion. No loss was observed in dark controls.

Key value for chemical safety assessment

Additional information

Kieber (1996) is a non-GLP, non-guideline study which follows scientific principles. There are limitations in reporting but there are adequate details for assessment. The study is considered reliable and suitable for use for this endpoint.
