In public available literature the authors present an update of environmental risk limits (ERLs), based on the literature, for nine trace elements, also for tin (Sn).
In this report for tin a log Kp soil:water of 3.28 L/kg is stated and a log Kp suspended matter:water of 5.57 L/kg.

Description of key information
In public available literature the authors present an update of environmental risk limits (ERLs), based on the literature, for nine trace elements, also for tin (Sn).
In this report for tin a log Kpsoil:water of 3.28 L/kg is stated and a log Kpsuspended matter:water of 5.57 L/kg.
Key value for chemical safety assessment
- Koc at 20 °C:
- 371 535.229
Additional information
Derived from the log Kp soil:water and log Kp suspended matter:water the Koc is determined to be 3715352.291 and 95273, respectively.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
