Description of key information

This class of substance is unstable under environmental and biological conditions and will readily hydrolyse to alcohols and sulphure dioxide / carbon dioxide with intermediary formation of carbon disulphide.  This is described in a number of reasearch papers and was confirmed though analysis of reaction products under synthetic gastric conditions. 

This is summarised in the attached report (which also serves to justify use of read-across data).

A number of biodegradationstudies have been performed on xanthates and the key degradation product carbon disulphide. Care is needed in the interpretation of the data as there will be a combination of biotic and abiotic processes.

Either way, there is clear evidence that the substance will not persist in the environment and will form metabolites that are themselves biodegradable or hydrolytically/photolytically unstable.
