Description of key information

Additional information

Data form simulation and environmental screening studies shows, that Sn(II) is only stable at pH values lower than 3. At higher pH values insoluble hydroxid speciees are formed. So at an pH of approx 4 the concentration of Sn(II) in the aquaticcolumn is lower than 10^5 mol /L. Similar values are determinatet in soil..

The facts, claculation and simulation data are discussed in the attachment
