The sorption of sulphur dioxide by PVC wallcoverings and conventional wallpaper samples has been measured at a maximum sulphur dioxide concentration of 150 μg/m3 by use of 35SO2. The sorption was found to be influenced by the surface finish and desi

The rate of deposition of gas-phase SO 2 to a variety of aqueous solutions has been measured. The deposition rate is unaffected by relative humidity. Some salts may cause a 3-fold decrease in deposition rate as the ionic strength changes from 0.1 M t
