ABSTRACTOFTHEDISSERTATION

Study on Techniques of Source Apportionment

of Airborne Particulate Using Chemical Mass Balance

(CMB)Receptor Model

By Feng Yinchang

Major：Environment Science

Written under the direction of Professor Zhu Tan

Chemical Mass Balance(CMBl receptor modeling has been shown to be an important technique in research of sources of atmospheric particulate matter(PM)and a scientific support for PM pollution prevention decisions．Atier more than 20 years’ development．it turns to be a significant PM source apportionment model and has made great contribution to PM pollution prevention．However,there are some problem in the application of CMB receptor model．The emphases of tllis dissertation are methodology and theory study about CMB receptor model and its application．The fundamentals and methods about sources profile construction have been put forward； A new method to solve the problem that a group of data often produces several outcomes has been brought forward，and a software including the method about CMB receptor model has been written in C language；The meaning of fugitive dust has been elucidated clearly,and the chemicals and source components of fugitive dust of Jinan

and Shi_jiazhuang cities have been characterized； Improved．．Source．．Apportionment

technique of atmospheric PM on the basis of study of emission and composition

characteristics of fugitive dust has been presented for the first time，the technique

solved the problem th
