PM2.5 Toxicity and Source Apportionment Data for the Yangtze River Delta

Fine particulate matter (PM2.5) toxicity data integrated with high-resolution emission inventories for the Yangtze River Delta region. The dataset, created by Xiwen Song and last updated in March 2026, includes source-specific toxicities derived from field measurements and cellular assays. It provides toxicity-adjusted population-weighted exposure estimates and contributions from sources like residential combustion and ship emissions.

Use Cases

• Prioritizing emission control measures based on source-specific toxicity contributions mentioned in the description
• Analyzing spatial disparities in health risk from PM2.5 based on toxicity-adjusted exposure data
• Evaluating cost-effectiveness of pollution abatement strategies for different sources like residential and industrial emissions
• Investigating correlations between socioeconomic factors (e.g., city-level income) and pollution toxicity

Strengths

• Integrates cellular toxicity assays with high-resolution emission inventories for health-oriented analysis
• Provides specific quantitative findings, such as residential combustion contributing 74.4% of toxicity in winter
• Includes confidence intervals (e.g., 95% CI: [62.9%, 85.9%]) for key toxicity contributions

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is limited to the Yangtze River Delta region and may not be generalizable
