Chemical mass balance model (CMB model) is one of several receptor models applied to air pollution source management. CMB model was first proposed by Miller, Friedlander and hidy in 1972, and formally named as chemical mass balance method by Cooper and Watson in 1980. It is an important method recommended by EPA to study the sources and contributions of PM10, PM2.5 and VOC.. The CMB model established by this method is the most studied and widely used receptor model in the practical work of source apportionment of atmospheric particulates. Chemical mass balance (CMB) model epa-cmbv8.2 is one of several receptor models applied to air quality problems in the past 20 years. Based on the least squares method of effective variance (EVLS), EPA supports CMB as a regulatory planning tool by approving a large number of state implementation plans (SIPS). CMB needs potential sources of analytical samples collected at a single receptor site and corresponding environmental data. CMB is an ideal tool for ideal local non reaching problems and has been proved to be a useful tool.
