PM_(2.5) pollution in households involved with solid fuel burning practices: Application of receptor models for source apportionment

摘要

1. Source apportionment results of indoor PM_(2.5) using three different air quality receptor models have shown comparable results 2. The results confirmed that emissions resulting from solid fuel combustion, road-traffic, cement and iron processing industrial activities are dominant contributors to slum-indoor PM_(2.5) mass. 3. CMB is found more sensitive for specific source identification and contribution estimations whereas PMF is able to differentiate source categories of indoor PM_(2.5) 4. The chemical species associated to particles emitted from solid fuel combustion causes several non-carcinogenic and carcinogenic health risk on resident's health. 5. The affordable and strong strategies require to switching clean fuel and advance stoves uses along with proper ventilation systems in Indian low-income urban and rural households.
