NSI Topsoil Palladium

The map covers England and Wales showing interpolated values of topsoil Palladium concentrations (mg/kg) at a 1km grid resolution.

The concentrations of palladium were determined using energy dispersive X-ray fluorescence spectrometry with a lower limit of detection of 0.25 mg/kg and typical coefficients of variation of greater than 50 % for repeated analyses of certified reference materials. The coefficient of variation (CV) expresses the error associated with subsampling and analysis; CV values of less than around 10 % suggest that analyses are reasonably accurate.
