摘要：The amount of concentration and spreading distance of air pollutant emitted from industrial area has implications for changes in ambient air. The aim of research was to know the change of ambient air in Cilegon city. To achieve this objective, the research was conducted by emission analysis and distribution of SO2 and dust pollutants emitted from the industrial estate. Hence, the researchers used distribution of industrial pollutants by using Screen 3 software while the dispersion was used Lagrangian model. To validate the change of ambient air in Cilegon city, the measurement was done on 18 sample points. The results show that the amount of concentration of SO2 pollutants had an impact on the change of ambient air in Taman Sari Village, Pulomerak District. Meanwhile, the impact of dust pollution changes the ambient air in Kotabumi village, the district of Purwakarta and Gerem Village in Grogol District.
