SOURCE APPORTIONMENT OF VOCS BY RECEPTOR MODELLING IN AN URBAN SITE IN HA NOI

Spatial/Temporal Variations and Source Apportionment of VOCs Monitored at Community Scale in an Urban Area

This study aimed to characterize spatial/temporal variations of ambient volatile organic compounds (VOCs) using a community-scale monitoring approach and identify the main sources of concern in Paterson, NJ, an urban area with mixed sources of VOCs. VOC samples were simultaneously collected from three local source-dominated (i.e., commercial, industrial, and mobile) sites in Paterson and one ba...

Source apportionment of submicron organic aerosols at an urban site by factor analytical modelling of aerosol mass spectra

Submicron ambient aerosol was characterized in summer 2005 at an urban background site in Zurich, Switzerland, during a three-week measurement campaign. Highly time-resolved samples of non-refractory aerosol components were analyzed with an Aerodyne aerosol mass spectrometer (AMS). Positive matrix factorization (PMF) was used for the first time for aerosol mass spectra to identify the main comp...

Source Apportionment of Pm2.5 in Urban Areas Using Multiple Linear Regression as an Inverse Modelling Technique

In many countries emissions of particulate matter from urban sources, such as traffic and domestic wood burning, can lead to high episodic concentrations. Though it is important for air quality management and exposure studies to understand the individual source contributions to these concentrations, the complexity of the urban environment does not always allow a clear separation of sources when...
