Topsoil Mercury Concentrations and Emissions

Supporting data for a 2026 study includes topsoil mercury concentration, non-residual mercury concentration, and mercury emission measurements. The dataset also contains results from Fourier-transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) analysis. It is structured across five distinct supporting data files.

Use Cases

• Modeling mercury emission fluxes based on topsoil ΔHg(0) emission measurements.
• Assessing bioavailable mercury pools using topsoil non-residual Hg concentration data.
• Characterizing soil organic matter composition via FT-ICR-MS results.
• Mapping soil mercury contamination risk using geospatial concentration data.

Strengths

• Dataset is large, with a total size of approximately 296 MB.
• Data is openly licensed under CC-BY-4.0, facilitating reuse.
• Provides multiple related measurements (concentration, emission, speciation) for integrated analysis.

Limitations

• Column names and exact row counts are not provided, limiting immediate understanding of data structure.
• The temporal and geographic coverage of the soil samples is not specified.
• Relies on inferred data types from descriptions; specific file formats (e.g., TIF) suggest geospatial components but are not fully detailed.
