AbstractConcentrations of cadmium in agricultural soils in the province of Skåne, southern Sweden, were shown to vary with geological substratum. The highest levels were found in areas dominated by Cambrian bedrock. Significant differences between general soil types were also recorded. Regional maps of cadmium in soil and winter wheat grain were produced with geostatistical interpolation. The variability of soil cadmium was relatively small in most parts of the area investigated, with high values restricted to the southeastern part. A spatial correlation pattern existed between a map of cadmium deposition based on moss analysis and the map of cadmium in wheat. Biogeochemical cadmium data and soil cadmium were correlated only in areas extremly high in biochemical cadmium.
