Some chemical elements, including arsenic (As), cadmium (Cd), chromium (Cr), mercury (Hg), nickel (Ni), selenium (Se) and lead (Pb) may occur in soils at concentrations, which could cause a significant possibility of significant harm to human health.
The Environment Agency (EA) has developed soil guideline values (SGV) which can be used in support of the application of the statutory regimes addressing land contamination, especially Part 2A of the Environmental Protection Act 1990 in England and Wales, and also development control under the Town and Country Planning Acts.
The BGS holds substantial datasets for As, Cd, Cr, Ni, and Pb in soil samples for parts of the UK and stream sediments for most of the UK.
The Imperial College Wolfson stream sediment data was used to complete the geochemical data coverage of the UK.
These geochemical data have been used to derive geospatial data sets that identify the estimated concentrations of As, Cd, Cr, Ni and Pb (mg kg-1) in soils.
Reports generated from this spatial data will help to inform planning decisions and to aid environmental consultants, developers, householders and their legal representatives.
