Estimated Ambient Background Soil Chemistry England and Wales
2012
creation
http://data.bgs.ac.uk/id/dataHolding/13605689
The Estimated Ambient Background Soil Chemistry England and Wales dataset indicates the estimated geometric mean topsoil Arsenic(As), Cadmium (Cd), Cr (Chromium), Nickel (Ni) and Lead (Pb) concentrations (mg kg-1). The soil chemistry data is based on GBASE (Geochemical Baseline Survey of the Environment) soil geochemical data where these are available. Elsewhere the stream sediment data are converted to surface soil equivalent potentially harmful element (PHE) concentrations. This dataset covers England and Wales but data is available for the whole of Great Britain, with the exception of the London area where an inadequate number of geochemical samples are available at the moment.

Either: (i) the dataset is made freely available, e.g. via the Internet, for a restricted category of use (e.g. educational use only); or (ii) the dataset has not been formally approved by BGS for access and use by external clients under licence, but its use may be permitted under alternative formal arrangements; or (iii) the dataset contains 3rd party data or information obtained by BGS under terms and conditions that must be consulted in order to determine the permitted usage of the dataset. Refer to the BGS staff member responsible for the creation of the dataset if further advice is required. He / she should be familiar with the composition of the dataset, particularly with regard to 3rd party IPR contained in it, and any resultant use restrictions. This staff member should revert to the IPR Section (ipr@bgs.ac.uk) for advice, should the position not be clear.
The dataset is made available to external clients under BGS Digital Data Licence terms and conditions. Revert to the IPR Section (DigitalLE@bgs.ac.uk) if further advice is required with regard to permitted usage.

The soil chemistry data is based on GBASE soil geochemical data where these are available. Elsewhere the stream sediment data are converted to surface soil equivalent potentially harmful element (PHE) concentrations using delineations of Parent Material (PM) polygons as the soil geochemistry mapping unit and the statistical relationships between soil and stream sediment data to derive the equivalent soil PHE concentration from the stream sediment data. Where only Wolfson stream sediment data are available in southern England, these data are first transformed to G-BASE equivalent sediment concentrations, and then to soil equivalent concentrations. Geometric mean Ambient Background Concentrations (ABCs) for PHEs in mineral soils are mapped within delineations of Parent Material PM polygons to produce a seamless data set covering the whole of Great Britain, with the exception of the London area where an inadequate number of geochemical samples are available at the moment. PHE concentrations in organic soils (i.e. with more than 15-20% organic carbon) are likely to be significantly lower than those indicated by the ESTIMATED SOIL PHE DATA.
