Abstract:
The current study was conducted, from October 2013 to September 2014, aimed to identify the temporal and spatial variations of air pollutants in stationary sites included Basrah oil refinery and southern gas company in addition to sources included intersections traffic in Basrah province (Alkzizah, Tigari and Jazaier streets).The results showed that in Basrah oil refinery the CO and SO2 concentration were less than the national and World Health Organization standards, while NOX were higher than the national and global standards reached 1ppm.The second site, which is southern gas company was as follows : CO gas was less than the national and global standards as well as NOX, while SO 2 was higher than the national and global standards reached 0.63 ppm.For intersections traffic sites (intersections)the results was as follows : CO was less than the national and global standards, while NOX was higher than the national and global standards reached 2.75ppm as well as SO2 at all intersections reached 0.65 ppm.Ambient air quality was recorded through the seasons of the year using the accurate measurement devices in various study sites of the province of Basrah. The results were indicated that the concentration of all the gases rate was higher in the winter than those recorded in summer due to the difference in climatic conditions, especially wind speed and direction, air temperature and moisture.The results showed a temporal and spatial variations in concentrations of studied air pollutants in ambient air interchanges traffic roads within the province of Basrah centerdue to difference in the rush hours , the activities of the various rights in traveling or shopping as well as the routine jobs procedure of the official working hours.The study showed variation in the concentrations of total suspended particles and black carbon among studied traffic intersection recorded highest concentration of black carbon at Quzaizah amounted to 27 μg/ m3 As the TSP recorded less concentrations 392 μg/ m3. But at the intersection of Tijari Street has concentrations of black carbon amounted to 11.3 μg/ m3 ,As for particles recorded 412 μg/ m3, either at the intersection of Jazair Street was recorded black carbon of 16.2 μg/ m3, As for particles amounted to 420 μg/ m3.All intersections have exceeded the global limitations of particles amounted of 150 μg/ m3 and local of 350 μg/ m3It can be concluded from the current study that the province of Basrah are polluted by air pollutant NOX gas in Basrah oil refinery and SO2 in the site Southern gas company NOX and SO2 at all intersections traffic sites located within the current study.
