The Chemical Mass Balance (CMB) receptor model uses chemical composition measured in the source and receptor samples to estimate the relative contributions of different source categories to ambient particulate concentration. The manual describes the CMB7 receptor model software. It is designed to allow users to use the CMB receptor model constructively with a few hour's learning time. Emphasizing rapid command of modeling procedures, the manual covers primarily the mechanical aspects of operating the model. Information on the theoretical basic principles of CMB receptor modeling is also briefly explained in the appendices. The manual is intended for wide use by State and local air pollution control agency personnel in developing State Implementation Plans for PM10. The U.S. Environmental Protection Agency has published a companion document to this manual that should be consulted for this application. The Protocol for Applying and Validating the CMB Model, EPA-450/4-87-010, provides guidance on applicability, assumptions and interpretation of results. This protocol provides a practical strategy for obtaining valid results.
