This dataset has now been superseded, please see the Measured Urban Soil Chemistry dataset. The BGS digital point source urban soil chemistry data (GB_PointSourceUrbanSoilPHE_v1) comprises the locations and concentrations (mg kg-1) of Arsenic (As), Cadmium (Cd), Chromium (Cr), Nickel (Ni) and Lead (Pb) in urban topsoil samples. The data is derived from the national, high resolution urban soil geochemical data from the BGS Geochemical Baseline Survey of the Environment (G-BASE) project. The information is relevant for the first stage of any assessment of risks to human health required by regulatory authorities in relation to land use and also for assessing ecological risk. Although point source PHE (Potentially Harmful Element) concentrations above respective SGVs (Soil Guideline Value) do not necessarily imply a significant health risk, they do highlight the need to consider whether or not there may be a risk. The urban soil chemistry data can be used to assist Local Planning Authorities to identify those areas where a risk assessment may need to be carried out by developers. Comparison of this spatially referenced geochemical data with information on current or historic land use and geological information might help environmental professionals decide whether high PHE concentrations in topsoils can be attributed to geogenic or anthropogenic sources. The point source data is based on an interpretation of the records in the possession of the BGS at the time the dataset was created.

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.
