Optimizing the SO sub(2) total emission control strategy: case study--Bor (Serbia)

A geographic information system (GIS)--based on spatial analysis--was developed for optimizing the SO sub(2) total emission cut scheme on air pollution in Bor (Serbia), combined with Models-3 modeling system and linear programming model. GIS is mainly used for establishing a multifactor assessment model to quantitatively divide environmental functional zone and also used for selecting control sites in linear programming model. A linear programming model was developed to optimize the emission determined by SO sub(2) control measures. According to the obtained results, some large emissions need to be cut for about 50%. The improvement of the ecological environment is urgently needed for controlling the background SO sub(2) pollution in Bor.
