Description of key information

The half life period of tin(II) oxalate in water is 37.5 days and based on this value it can be concluded that the chemical is not persistent in water medium since the half life is less than the threshold of 60 days (to qualify the chemical as persistent). Also the diffusion percentage of tin(II) oxalate in water medium is 44.4%. This coupled with the dilution of water shall result in ready biodegradability of the chemical.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable
