Application of source-receptor models for air quality management

A review on the different receptor modeling techniques called the Chemical Mass Balance (CMB) for source apportionment, is discussed. The application of source-receptor air quality model to detect particle pollution affects is also discussed. Increased fine particulate concentrations has caused reduced visibility, decreased human health, and death. The standard ambient level approved by National Ambient Air quality Standards (NAAQS) is not maintained in the United states. The recently developed source-receptor model can overcome the limitations associated with the traditional dispersion models. The methodology is based on the concentrations of source-tracing chemical species measured at the receptor. The models are used in State Implementation Plans for achieving NAAQS compliance. The need to identify the sources for effective control strategies and regulations result in a number of apportionment studies.
