Urban particulate pollution source apportionment: definition, methodology, and resources

This paper arises from a concern over the lack of information (quantitatively) on the contributions of different source categories of air pollution in developing countries - especially for fine particulate matter (PM), which is the major contributor to the adverse health effects of air pollution. Without reliable and accurate source information, it is difficult for policymakers to formulate rational, effective policies and investments aimed at improving air quality. In SIM 010.2008, a number of sources are described that contribute to the particulate pollution (ranging from domestic combustion to transport sector
