A novel approach to long-term source contribution of ambient PM2.5 from residential solid fuel burning using the FUSTA methodology

Key Points

• To estimate the contributions of various sources to ambient PM2.5 over time, focusing on residential solid fuel burning.
• Applied the FUSTA methodology for estimating source contributions.
• Analyzed long-term PM2.5 data from various residential areas.
• Considered different types of solid fuels used for heating.
• Identified significant contributions of residential burning to overall PM2.5 levels.
• Provided a framework for ongoing air quality management efforts.
• Demonstrated the effectiveness of FUSTA for source apportionment of ambient pollutants.
