Introduction: This paper is an example for handling with monitoring data, which is about concentrations of sulphurdioxide (SO2) and particulate matters (PM10) (smoke) in İzmir according WHO guidelines (for several gases and particles).
Objective: The objective of this study is to evaluate air pollution in Izmir between 1989-2004. And to determine the effect of the changes of the measurement places to the air pollution measurements.
Materials and Methods: Data were obtained from The State Institute of Statistics (SIS) web page as the results of concentrations of SO2 and PM by city center on winter season from 1989 to 2003 years for Izmir. The time series analysis was used for statistical analysis of the air pollution between 1989-1996 and 1996-2004. Least square method was used for determine the corrected data, Trend analysis (b/Sb) and, for calculation the significance of the break of trends
formula was used (p<0,05).
Results : The concentrations of sulphurdioxide (SO2) and particulate matters (PM10) (smoke) in Izmir from 1989 to 1996 were above the WHO guidelines the allowed limits, but from 1989 to 2004 years concentrations of sulphurdioxide (SO2) and particulate matters (PM10) (smoke) decreased below the allowed limits without any preventive precautions in Izmir. And the measurement places were changed to the clean and fresh air places which could be effective on the air pollution.
Conclusion : Air pollution is a public health problem in Izmir, and for solving the problem it is necessary reorganization and scientific approach for air pollution management.
