Statement

The data is derived from soil geochemical surveys have been carried out at 22 urban centres in England, Scotland and Wales. Nineteen of the surveys were undertaken by the BGS as part of the Geochemical Surveys of Urban Environments (GSUE) project (Fordyce et al., 2005), whereas Wolverhampton, Manchester and Glasgow were sampled as part of larger multi-disciplinary projects. The concentrations of many potentially harmful elements including arsenic (As), cadmium (Cd), chromium (Cr), nickel (Ni), and lead (Pb) are above 'natural' background in urban environments as a result of a range of contaminative processes. Urban geochemical surveying is based on the collection of samples on a 500 m grid at a density of approximately 4 samples per km2 across the urban areas. Samples were collected from open ground as close as possible to the centre of each 500 m grid cell. At each sample site, composite samples based on 5 sub-samples taken at the centre and four corners of a 20m square, were collected from the topsoil ('A' soil sample; 5-20 cm depth) and subsurface ('S'soil sample; 35-50 cm depth). Approximately 40 chemical elements were determined in the <2mm size fraction of the 'A' soils. Either the <150 micron or <2mm fraction of the 'S' soil samples were analysed.
