Data from projects that investigated the migration, transport and retardation processes of naturally occuring trace elements, as analogues the behaviour in the geosphere environment, of radionuclides from radioactive wastes. Study sites included: the Quaternary Broubster Peat Bog, near Thurso in Caithness (study of the migration behaviour and characteristics of U, Th, Ra, Pb, Cu, Zn, organic complexes such as fulvic and humic acids); the Needle's Eye site (Quaternary estuarine and marsh/mudflat sediments) on the Solway Coast of Dumfries and Galloway (study of the migration and retardation behaviour of U in Quaternary sediments and fractured Palaeozoic source rocks); Study of U geochemistry and transport behaviour from uranium-rich mine wastes at the South Terras Mine site, near St Austell, Cornwall; Study of the geochemistry of diffusion of Cl and I from marine source sediments into lacustrine sediments in Quaternary sediments from Loch Lomond. Data consists entirely of published reports of geological, geochemical, hydrochemical petrological and mineralogical information. The data includes descriptive and numerical data but is not digitally available in its present state.
This layer displays the urban areas for which there is an "urban geochemical mapping" report. An integral part of the G-BASE (Geochemical Baseline Survey of the Environment) mapping programme is to map and establish the soil geochemical baselines of urban areas. These data provide unique soil chemical information for the urban environment and are used to; assess the condition of soils within populated areas, identify and quantify human impact on soils in urban areas through comparison with the rural, natural soil geochemical background and Indicate elevated concentrations of potential harmful elements. 27 urban areas which have been sampled by the project to date.These include Glasgow, Nottingham, Ipswich and Cardiff.
Soil samples collected in urban areas throughout the UK are analysed for their major and trace element geochemistry, their pH and organic matter content. Samples are collected at two depths; 0-15cm and 35-45cm at sites selected using a stratified, random design. The data can be used to identify and prioritize contaminated sites. In 1993, the Geochemical Baseline Survey Of The Environm (G-BASE) rural geochemical mapping programme was extended to include sampling in urban areas and to date around 22 urban centres have been sampled. Data is available on key inorganic contaminants including Cr, Cu, Cd, Ni, As, Pb, Zn, Sn and Sb. Results have been standardised to ensure seamless joins between geochemical sampling campaigns. Urban centres are selected in areas where rural sampling is undertaken or where the BGS urban programme is active. Urban centres will continue to be sampled until completion of the rural programme, scheduled for 2015.
This layer of the map based index (GeoIndex) shows the boundaries of the G-BASE (Geochemical Baseline Survey of the Environment) project mapping areas which are reported as geochemical atlases. The majority of atlases are for stream sediments, with data on stream waters and soils included when available. Separate stream sediment, soil and stream water atlases have been published for Wales. Wales and north of Humber-Trent are reported as hardcopy generally A3 sized publications. The Humber-Trent atlas is available as a pdf file on a CD-ROM. Atlases are available for Shetland, Orkney, South Orkney and Caithness, Sutherland, Hebrides, Great Glen, East Grampians, Argyll, Southern Scotland, Lake District, NE England, NW England and N Wales, Humber-Trent, Wales and West Midlands. Atlases are not available yet for the East Midlands, East Anglia, SE England and SW England.
The full title of this project is" Studies into metal speciation and bioavailability to assist risk assessment and remediation of brownfield sites in urban areas" and is funded by NERC under the URGENT thematic programme form 1998-2001. The project is being undertaken by a consortium of workers from the Imperial College, University of Nottingham, and the British Geological Survey. Innovative collaborative and multi-disciplinary research will be applied to the interpretation of urban geochemical maps and associated meta-datasets to assist decision making by local authorities in the redevelopment of brownfield sites. Source apportionment, speciation and bioavailability of potentially toxic heavy metals will be studied at representative conurbations in the UK Midlands region. Scanning electron microscopy, chemical extractions and soil solution and vegetable analysis, will be integrated with high precision isotopic analyses of Pb and other potential toxic metals in this study. The results will be available as maps in GIS format to provide a generic decision support system for quantitative health risk assessment.

The BGS has been commissioned by Defra to provide guidance on what are 'normal' levels of contaminant concentrations in English soils in support of the revision of the Part 2A Contaminated Land Statutory Guidance. The domain polygons and other data produced by this work are served as WMS here.
BGS have collected environmental radioactivity data for various purposes over several decades. This is being drawn together to produce a database of baseline gamma radioactivity and radon. Data includes the relevant portions of airborne and ground gamma spectrometer surveys, mineral exploration, baseline geochemistry and environmental radiometric surveys along with lithogeochemical and borehole log data. It is predominantly a specialist subset of other existing BGS databases. Incomplete UK coverage.
This dataset of paper records holds details of analysis of all the sample batches (from both internal and external customers) analysed by the Analytical Geochemistry Laboratory of the BGS since June 1996. It was installed to underpin the UKAS (United Kingdom Accreditation Service) accreditation of the geochemistry laboratories at Keyworth, which was awarded in August 1999. There is a file for each batch of samples submitted for analysis. The file documents the progress of the samples through the laboratories, including sample registration, sample processing, raw data from analytical instruments and the data reported to the client. The records are archived to provide supporting evidence for any query regarding geochemical data provided by the laboratories.
THIS DATASET HAS BEEN WITHDRAWN **This dataset was created for the "Britain beneath our feet" atlas using information extracted from the Geochemical Baseline Survey Of The Environment (G-BASE) For The UK . For Fluoride in Stream Water data please see Geochemical Baseline Survey Of The Environment (G-BASE) For The UK ** Geochemical Baseline Survey of the Environment (G-BASE) coverage for Fluoride in stream water. The G-BASE programme involves systematic sampling and the determination of chemical elements in samples of stream sediment, stream water and, locally, soil, to build up a picture of the surface chemistry of the UK. The average sample density for stream sediments and water is about one site per 1.5-2km square. Analytical precision is high with strict quality control to ensure countrywide consistency. Results have been standardised to ensure seamless joins between geochemical sampling campaigns. The data provide baseline information on the natural abundances of elements, against which anomalous values due to such factors as mineralisation and industrial contamination may be compared. Published in Britain beneath our feet atlas.
