Wildfire Effects on Soil Nanoparticle Composition and Concentration in Central Chile

A dataset from a study investigating nanoparticle dynamics following a wildfire in the Cantillana Reserve, central Chile. The research combines field sampling, controlled combustion experiments, bulk geochemical analyses, and single-particle ICP-TOFMS. It was authored by Cristian Suarez-Oubiña and last updated on 2026-04-21.

Use Cases

• Modeling nanoparticle number concentration changes after fire based on reported measurements up to 1.4 × 10^9 particles per gram.
• Analyzing shifts in nanoparticle composition from monometallic to multimetallic (e.g., Fe–Mn–Ti, Fe–Zn) as described in the results.
• Investigating post-fire metal mobility using data on smaller nanoparticles enriched in Pb and Zn.
• Developing geochemical indicators of wildfire severity using bimetallic nanoparticle ratios like Fe/Mn and Fe/Zn mentioned in the study.

Strengths

• Includes specific quantitative findings, such as nanoparticle concentrations reaching up to 1.4 × 10^9 particles per gram.
• Combines multiple methodologies: field sampling, lab experiments, bulk analyses, and single-particle ICP-TOFMS.
• Released under a permissive CC-BY-4.0 license, facilitating reuse.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• The dataset is relatively small at 10.2 MB, potentially limiting the scope of analysis.
• Data freshness should be verified as the last update date is in the future (2026-04-21).
