Analysis of Air Quality in Xujiahui Area of Shanghai

[Objective] To investigate the air quality in Xujiahui Area of Shanghai.[Methods]A Monitoring Station has been set up in Xujiahui Area.With the aid of automatic continuous monitoring analyzer,the primary pollutants of SO_2,NO_2 and PM_(10)in the air were detected and analyzed.[Results] The annual daily average concentrations of SO_2,NO_2 and PM_(10)in Xujiahui Area varied among 0.005～0.224mg/m~3,0.016～0.148 mg/m~3 and 0.012～0.294 mg/m~3 respectively.The corresponding annual average concentrations were 0.066 mg/m~3,0.069 mg/m~3 and 0.085 mg/m~3.The results of monitoring and analysis indicated that the pollution of NO_2 in Xujiahui Area was more serious than that of PM_(10)and SO_2.The pollution was also more serious in winter and spring than that in summer and autumn.[Conclusion] The pollutant NO_2 in this area apparently relates to the busy traffic of motor vehicles in this area.The PM_(10)relates not only to motor vehicles,hut also to other pollution sources.The influence on NO_2 pollution resulted from specific geographical location is obviously higher than that on PM_(10)and SO_2.The air pollution in this area has a clear feature of traffic pollution by motor vehicles.
