London Earth provides X-ray fluorescence spectrometry measurements of chemical elements in urban topsoil, collected as part of the national Geochemical Baseline Survey of the Environment. The British Geological Survey analyzed soil samples within the Greater London Authority administrative boundary, presenting results in an Excel file.
Use Cases
- Map the spatial distribution of heavy metals like Lead, Cadmium, and Arsenic across Greater London for environmental risk assessment.
- Analyze correlations between soil elements such as Iron, Zinc, and Copper to study urban geochemical processes.
- Establish baseline concentrations for elements including Chromium, Nickel, and Selenium to monitor future soil contamination changes.
Strengths
- Data originates from the authoritative British Geological Survey laboratories using standardized X-ray fluorescence spectrometry.
- Focuses on the defined and densely populated Greater London Authority administrative area.
- Includes measurements for multiple analytically significant elements like Cadmium, Lead, and Arsenic.
Limitations
- Sample size, row count, and specific column structure are unknown, limiting assessment of statistical power.
- Data format is a single Microsoft Excel file without documented schema, complicating programmatic access.
