Laboratory results for the analysis of soil samples collected from urban areas during the baseline geochemical mapping programme of Britain. Sample sites are described on field slips. Chemical results are subjected to high level of quality control in the laboratory. Results are the raw data processed (standardisation and normalisation) to give seamless geochemical images and the value added G-BASE (Geochemical Baseline Survey of the Environment) data in the BGS geochemistry database.

Programme of research funded by the Natural Environment Research Council. URGENT aims to stimulate the regeneration of the urban environment through understanding and managing the interaction of natural and man-made processes. Projects throughout the UK first set up in 1997 and completed in 2005. It was supported by partners from British industry, local authorities and Government agencies. A total of 40 URGENT projects in four key areas - air, water, soil and ecology. The projects aim was to determine the magnitude of urban environmental problems and risks, to understand the underlying patterns and processes that affect them, and to produce effective strategies for control and managment which will be accessible to users both in the UK and abroad.

Laboratory results for the analysis of geochemical samples (stream sediments, soil and water) collected for the high resolution geochemical mapping of mainland Britain. The programme of regional geochemical sampling began in 1968 in the northern Highlands of Scotland. Sample sites are described on field slips. Chemical results are subjected to high level of quality control in the laboratory. Results are the raw data processed (standardisation and normalisation) to give seamless geochemical images and the value added G-BASE (Geochemical Baseline Survey of the Environment ) data in the BGS geochemistry database.

Concentrations of total organic carbon (TOC), total petroleum hydrocarbons, polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) were determined in 84 near-surface soils (5-20 cm depth) taken from a 255 km2 area of Glasgow in the Clyde Basin, UK, during July 2011. Total petroleum hydrocarbon ranged from 79-2,505 mg kg-1 (mean 388 mg kg-1; median 272 mg kg-1) of which the aromatic fraction was 13-74 % (mean 44 %, median 43 %) and saturates were 28-87 % (mean 56 %, median 57 %). Σ16 PAH varied from 2-653 mg kg-1 (mean 32.4 mg kg-1; median 12.5mg kg-1) and Σ31 PAH range was 2.47-852 mg kg-1 (mean 45.4 mg kg-1; median 19.0 mg kg-1). PCB tri-hepta range was 2.2-1052 mg kg-1 (mean 32.4 mg kg-1; median 12.7 mg kg-1) and the ΣPCB7 was 0.3-344 mg kg-1 (mean 9.8 mg kg-1; median 2.7 mg kg-1).

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.

This dataset presents major (ICP-OES) and minor (ICP-MS) element data and fluid pH during interaction of simulated fracturing fluids with the Bowland-Hodder shale at a variety of conditions, i.e. fluid acidity (pH 1-5), temperature (25-70 C), and rock/fluid ratio (from 0.2:200 to 20:200), as well as two end member mineralogical compositions (from 618 m depth and 673 m depth). The data was collected under the SECURe (Subsurface Evaluation of CCS and Unconventional Risks funded under the European Union’s Horizon 2020 research and innovation programme under grant agreement number 764531.
