Effects of Air Pollutants from Al-Dura Power plant in the Surrounding Area South Baghdad

Thermal power stations are one of the main pollution sources in Baghdad that release many toxic substances in the environment and cause toxic effects on public health. Three selected sites were selected with gradual distances from Al-Daura thermal power station within (0.5 Km (st. 1), 1 Km (st. 2) and 2 Km (st. 3), respectively) according to the direction of downwind of site. In addition, one of unpolluted site was chosen for comparison as a control site around 4 Km upwind from Al-Daura thermal power station. The samples were taken for two seasons,winter 2014 and spring 2015; the first season was in December 2014 and the second season was in March 2015. The concentrations of some pollutants that originated from Al-Daura thermal power station as air pollutants were measured. The results of air analysis showed high concentrations of Sulphur dioxide (SO2), Nitrogen dioxide (NO2), Hydrogen Sulfide (H2S) and volatile organic components (VOCs) in all three sites in comparison with control site, and the higher values for SO2, NO2 and H2S were shown in site 3; while the concentrations of VOC were higher in site 2. There are no significant differences in concentrations between the air pollutants in the two seasons, except for SO2, which were increased in the first season than in the second season.
