Abstract:
In this study , data of gaseous pollution in the atmosphere (Carbon monoxide CO,Nitrogen Dioxide NO2and Sulfur Dioxide SO2) and in two selected stations ( the first lies in north of Baghdad in AL - Rusafa and the other lies in south of Baghdad in AL - Karkh ) are analyzed . Data was taken from Division of air pollution and environment improvement ( technical department ) of Ministry of Environment / Baghdad and for years ( 2010 ,2011 and 2012) . In addition some metrological factors are studied and treatment methods have been selected , Also the concentrations of Carbon dioxide CO2 in atmosphere are analyzed as pollutants and cause of global warming which may be effected on Baghdad weather . Results show that at AL - Jadiriya station the concentrations of gases : ( Carbon monoxide CO, Nitrogen Dioxide NO2 and Sulfur Dioxide SO2 ) reaches the order (1.24, 0.07 and0.055 ) ppmrespectively as high value . In AL - Wazirirya station , the maximum value of ( Carbon monoxide CO, Nitrogen Dioxide NO2 and Sulfur Dioxide SO2) reaches ( 1.50 , 0.06 and 0.06) ppm respectively as hourly rates . Results show clear behavior of metrological factors on these pollutants for months and season , results have indicated that the carbon monoxide CO concentration reaches relatively maximum values during winter . For the monthly and quarterly , maximum values of Nitrogen Dioxide NO2 are at summer and winter . Maximum value of Sulfur Dioxide SO2 is at summer . It was found that the concentration of pollutants are directly proportional to the temperature and inversely proportional with both speed of wind and relative humidity . Results show that the maximum value of Carbon dioxide CO2 at autumn and it reaches (420 ppm ) and concentration of pollutants inversely proportional with both speed and direction of wind and temperature.
