Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
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
Additional information
No. of studies reviewed for Biodegradation in water:screening tests from reliable sources having Klimisch rating 2.
The summary of the results are presented below
Sr.No | Endpoint | Percentage Degradation | Half - Life | Parameter | Sources |
1 | Ready biodegradability | 50% degradation | 37.5 days | Half-life | Predicted data from PBT profiler |
2 | Ready biodegradability | 90.26 % degradation | 15 days | O2 consumption | Predicted data from QSAR |
By applying weight of evidence approach to the target chemical tin(II) oxalate it was found that the degradation percentage of tin(II) oxalate in water medium is 50 to 90.26 %.This result in ready biodegradability of the chemical.
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).
