Description
Point source data provides locations and concentrations in mg kg-1 for Arsenic, Cadmium, Chromium, Nickel, and Lead in urban topsoil. The dataset, created by the British Geological Survey, is derived from high-resolution geochemical surveys to assist in land-use planning and pollution source attribution.
Use Cases
Map concentrations of Arsenic, Cadmium, Chromium, Nickel, and Lead to identify urban areas with elevated heavy metal levels for risk assessment.
Compare point source concentration data with land-use records to attribute high metal levels to geogenic or anthropogenic sources.
Use spatially interpolated estimated geometric mean concentrations to model topsoil pollution gradients across urban landscapes.
Strengths
Data originates from the high-resolution BGS Geochemical Baseline Survey of the Environment (G-BASE) project.
Focuses on five environmentally significant heavy metals: Arsenic, Cadmium, Chromium, Nickel, and Lead.
Limitations
The dataset has been superseded by an estimated version, indicating the point source data may not be the current authoritative source.
Based on and limited to BGS records available at creation time, potentially omitting newer samples or areas.
