Title: “Quantitative assessment of emission source contributions to ambient air pollution”
Abstract
A key question to ask in developing a clean air action plan for a geographical domain is where the pollution comes from. Is it mainly from local,
regional or trans-boundary emission sources and how much is from atmospheric transformation processes? This science-based information is
useful in prioritizing emission control efforts to improve air quality. Integrated approach relying on the technical tools can be used to answer the
questions. Emission inventory is used to quantify the atmospheric pollution loads from the sources located within the domain. Dispersion
modeling can be used to analyze the contributions from different source categories and/or source regions, both inside and outside the domain. As for particulate matter and volatile organic compounds, when a suitable composition monitoring dataset is available, source apportionment by
receptor modeling can be applied to quantify sources’ contributions to the pollution at receptor sites. Case studies from Southeast Asia are
provided to illustrate such integrated approach when the technical tools are used in combination to better reveal the source-receptor relationship.
