Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Executive summary:

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.
