British Geological Survey data provides estimated geometric mean topsoil concentrations for five potentially harmful elements: Arsenic, Cadmium, Chromium, Nickel, and Lead. The dataset covers Scotland and is derived from GBASE stream sediment data converted to soil-equivalent values.
Use Cases
- Map spatial distribution of Lead (Pb) and Arsenic (As) concentrations to identify regional contamination hotspots in Scotland
- Analyze correlations between estimated Cadmium (Cd) and Chromium (Cr) levels for environmental risk assessment
- Establish baseline Nickel (Ni) concentrations across Scottish topsoil for future pollution monitoring
- Model estimated topsoil concentrations of potentially harmful elements (PHEs) for land-use planning
Strengths
- Data from the authoritative British Geological Survey (BGS)
- Covers five specific heavy metals: Arsenic, Cadmium, Chromium, Nickel, and Lead
- Based on the GBASE (Geochemical Baseline Survey of the Environment) methodology
Limitations
- Data for the London area is excluded due to an inadequate number of geochemical samples
- Values are estimated conversions from stream sediment data, not direct soil measurements
- Specific sample count, spatial resolution, and uncertainty metrics are not provided
