British Geological Survey data provides estimated geometric mean topsoil concentrations of Arsenic, Cadmium, Chromium, Nickel, and Lead across England and Wales. The dataset is derived from GBASE soil geochemical data and converted stream sediment measurements, covering Great Britain except the London area due to insufficient samples.
Use Cases
- Map spatial distributions of topsoil Arsenic and Lead concentrations to identify potential contamination hotspots.
- Analyze correlations between Cadmium, Chromium, and Nickel levels to study geochemical associations in soil.
- Establish regional baselines for Potentially Harmful Element concentrations using the geometric mean estimates.
- Compare soil chemistry estimates derived from GBASE data with those converted from stream sediment data.
Strengths
- Data covers England and Wales with availability for most of Great Britain.
- Provides estimates for five specific Potentially Harmful Elements: Arsenic, Cadmium, Chromium, Nickel, and Lead.
- Based on the authoritative GBASE (Geochemical Baseline Survey of the Environment) program.
Limitations
- Excludes the London area due to an inadequate number of geochemical samples.
- Concentrations are estimates, not direct measurements, with some derived from converted stream sediment data.
- Specific sample count, spatial resolution, and measurement dates are not provided in the input.
