Air pollution in developing countries has recently become a serious environmental problem, which needs more active air quality monitoring and analyses. To assess air quality characteristics over the city of Baghdad. temporal variations in CO, NO, NO
2 , NOX, O3 , SO2 and PM10 Concentrations measured between May-December 2010 (245 days), at period from 8:00-16:00 daily hour from location called ALJadriyah station (44.1E -33.3N, 38.5m above sea level). From diurnal variability of these concentration, we see high daily values of CO and CH4 3.25, 1.9 PPM at November while NOX record 0.23 PPM at December that consider as highest daily value. While other pollutant concentration don't have large variation have 0.14-0.18 PPM. Particular matter at 10um (PM10 ) have 1.6g/m3 at 21/7/2010. At winter season and specifically at December month, there is good relation between the hourly concentration of PM10 and other chemical pollutant concentration such as CO,SO2 , NO, NOX this can be putting by correlation coefficient r =0.7-0.5. The monthly mean concentration of pollutant CO, NOX , CH4, NO, NO2 recorded high value at August Month. While O3 have large mean concentration in November, while PM10 have large monthly mean concentration at June and July months where there is most frequent dust-storm events. High concentration and its frequency distribution shifts towards large values concentrated at summer seasons June, July, Aug. about 0.25-1.25 PPM and have frequency percent about 82.6%. In winter the frequency distribution shifts towards large values of O3 even above 61.2% in range 0.085- 0.105 PPM. Regarding the frequency distribution of SO2 all season where shifts towards lower except spring (May) 88.2% at range concentration 0.025-0.125 PPM. Nitrate oxide have different concentration an frequency at several season but NOX have large frequency at summer, other pollutant concentration CH4 and PM10 have high concentration frequency at this period.
