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.
