Abstract:
تهدف هذه الدراسة الى دراسة وتحليل تاثير الخصائص المناخية في تركيز وترسيب ملوثات الهواء في محافظات البصرة وذي قار وميسان , وذلك من خلال جمع البيانات المناخية من الهياة العامة للانواء الجوية العراقية وتبويبها ومن ثم تحليل الخرائط الطقسية للمستوى الضغطي (100 | The aim of study is an analyzing the impact of the climatic characteristics in the concentration of air pollutants in provinces of Basra, Dhi Qar and Maysan, through collection and classifying the climate data which were got from the Iraqi meteorological organization and seismology , also th collection and analyzing the maps liturgical to level barotraumas (1000) milli bars from web site (Vortex Plymouth and NOAA ) for the period from (2003 to 2014) the purposes of analyzing them is to know the occurrences systems piezoelectricity which are effect on the, area of the study, of each them, and studying the climatic effects of associated with them to knowing its impact on the concentrations of polluting gases to the air and amounts falling dust variation over an study area of the study.The study deals wthe the measurement of concentrations of a range of gases in different locations in the region of the study and then compare them with previous studies and compared with the normal limits of gases in the atmosphere These gases are (mono carbon CO dioxide, and dual dioxide, CO2, and sulfur dioxide SO2, nitrogen oxides (NOx , NO2 , NO)In thes study we also collect falling dust samples per month for (September 2013 / August 2014)in nine location from (9) in the region of the study and weight them by using private balance then we record their weights for each location after wards the samples were collected every three months to represent one of the seasons and then analyzed them in a central laboratory of Iraqi Ministry of Environment to see the concentrations of heavy elements blended with falling dust particles has been confirmed on four heavy elements (copper, lead, nickel and iron) so we tested (36) samples seasons in each therefore a total of them were 144 checks, and then we study the impact of climatic characteristics in contrast temporal and spatial amounts falling dust qualitative and contrast the concentrations of heavy metals in the monitoring sites. The results of study : 1. All the rates at concentration which were recorded during the period (September 2013 / August 2014) exceeded the natural concentration for mono gas carbon dioxide (CO) in the air (0.1ppm).2 The climatic elements as the high temperatures and differing wind speed are impacting in the temporal variation of concentrations of gas (CO) in the measurement locations in Hartha site record in the month of(CO) was the highest in May,It was 20 ppm.3. All registered rates of concentrations of carbon dioxide (CO2) during the period (September 2013 / August 2014) exceeded the (CO2) concentration rate which were recorded before the Industrial Revolution (285ppm) in all measurement sites4.The climatic characteristics have been influence on the contrast of the spatial of the concentrations rates of (CO2) where the concentration rate of (CO2) was recorded(389.3ppm) in a technical college site in January, while it was recorded (400.7ppm) May and same way it was recorded 480 ppm in Alhabboubi square site in February while it increased in July until 630 ppm.5. The dual concentrations of sulfur dioxide gas rates (SO2) exceeded its natural concentration in the atmosphere of (0.001ppm( in all measurement locations6. The climatic characteristics have been influence on the contrast of concentrations levels of (SO2) per month in measurement sites during the period (September 2013 / August 2014),where it was (3.7ppm) in umm Qasr in January while it reached to(10.9ppm) month in April.7. The concentrations rate Monoxide nitrogen (NO) exceeded natural gas level in air (0.0025) at all measurement locations for all months during the period (September 2013/August 2014)8 A climatic characteristics contribute to vary the concentrations rates of (NO) in the measurement sites in limit time.The concentration rates of ( no ) were recorded (2.4ppm) Fao station in January while it rose to (4.0ppm ) in June.9. It is found that the concentrations of binary rates of nitrogen dioxide (NO2) exceeded the normal limits for the amount of gas in the air (0.01) in all measurement sites and for all months during the period (September 2013 / August 2014).10. The climatic characteristics have been influence on spatial contrast of the concentrations rates of (NO2) by months, in the measurement sites through divergence concentrations rates between cold months and hot months where the concentration rate of (NO2) was (12.2ppm) in the Fao site in January while it rose to (20.6ppm) in June.11. There is a variation amount of falling dust above monitor sites according to environmental monitor sites and according by time (September 2013 / August 2014),Thus recorded the Environment office in Dhi Qar site recorded a highest amount of falling dust at September (93.1 g / m2 / month) formed (26% ) of the total amount of dust recorded in September, while the lowest amount of falling dust was recorded in Al - ishar site site for the same month,it was (15.3 g / m2 / month) by (4.3%)12. The environmental monitor sites recorded a lowst amount of dust in January where the more amount of dust was recorded in the Environment office in Dhi Qar site , it was (29.6 g / m2 / month) while the lowest amount of dust was record in FAO station ,it was (4.2 g / m2 / month).13. The properties of hot season have been influence in the recorder amount of dust which were recorded in the environmental monitor sites , However the dust amounts which were recorded in June , July and August, more than that were recorded in December , January and February the highest falling amounts of dust were recorded in the environment department in Dhi Qar site (78 g / m2 / month) in June and the lowest of it was recorded in the Qurna (18.9 g / m2 / month(14. The volumes of falling dust were recorded more amount in the transitional seasons than the rest of the months in year. The highest amount were recorded in October while the lowest were recorded in the cold season , where all monitor sites were recorded the lowest amounts in January.15 The study demonstrated by measuring the concentrations of heavy metals in falling dust samples that the highest concentration of the element copper was recorded in Fao site in the summer theoretical separation (148.9 g / m 3), while the lowest concentrationwas in the theoretical spring (11.6 g / m 3) Environment office in Dhi Qar site.16. The highest concentration of lead was recorded in Basra Environment office in site element of in the autumn theoretical separation , it was (76 g / m 3), while the lowest concentrations were recorded in Environment office in Dhi Qar site at winter (11.4 g / m 17. The highest concentration of nickel element was recorded in Environment office site in Dhi Qar in all seasons of the year and the highest was in summer (117.3 g / m3) and the lowest was in winter (108.2 g / m 3).18. There is a high iron concentrations in the falling dust samples which were measured in all monitor sites and in all seasons so the highest concentration s were recorded in summer in each environmental monitor location.
