Abstract:
استهدفت الدراسة الحالية التي جرت في شوارع مدينة تكريت قياس تراكيز بعض الغازات المهمة التي تطرحها المركبات الى البيئة وهي احادي اوكسيد الكاربون, ثنائي اوكسيد الكاربون, ثنائي اوكسيد الكبريت (CO, CO2, SO2) وكذلك دراسة نوعية مياه الامطار المتساقطة على منطقة ا | The current study which takes place in the main streets of the city of Tikrit, aims at measuring the concentrations of some essential gases which are emitted by the vehicles of the environment. These gases include Monoxide Carbon, Dioxide Carbon and Sulfur Dioxide (CO, CO2, SO2). This study also aims at investigating the quality of rainwaters which are falling on the area of the study, and conducting some biological tests for them. Moreover, this study aims to identify the effect of vehicles productions upon blood physiology and the construction of some persons who are dealing with them. The samples have been collected during September 2010 till May 2011, and then classified in terms of age and duration of exposure. Alsuqoor Village represents the control group. A sample has been collected from healthy, non - smoker males. The concentrations of some polluted gases emitted from exhausted vehicles are identified. They are significantly high in comparison with the control group and during the whole chapters of the study. The highest level of pollution value is recorded by the gases (CO, CO2, SO2) and at (p< 0.05) level in Albasha Street during the Autumn, whereas the lowest value is recorded in Alzuhoor Street, during the Winter ( ). In addition, some of rainwater characteristics have been measured such as, (Ph, electrical m and the amount of plankton in water). The obtained results show that there is a significant decrease in PH concentration and a significant increase in EC concentration. Moreover, results indicate that the highest concentration of the clot material is in Alarbaeen Street ( ) whereas, the lowest concentration is in Alzuhoor Street ( ). The level of some rare elements has been measured in the blood serum of those who are exposed to (lead, cadmium) and in different periods of times. A significant increase is recorded in the levels of those elements, in comparison with the control group (ps 0.05). As for effect of blood components of those who are exposed to pollutants, the concentrations of both (Hb, Pcv) have been decreased with an increase in the concentrations of (the number of red and white cells and ESR) in comparison with the control group at level (P<0.05). It is also noticed that there is a significant increase in the number of the neutral and acidic white blood cells with a significant decrease in the number of the moral white blood cells at the lymph cell, in comparison with the control group. Results also show that there is a significant increase (P<0.05) in the level of each (Cholesterol, Triglycerides, and Lipoproteins with low density LDL) with decreased concentrations of (High Density Lipoproteins HDL) whereas, there are no significant difference in the concentrations of (Low density Lipoproteins Very high density VLDL). Concerning the concentrations of (Urea, Uric acid, Kreatenin) there is a significant increase (P<0.05) in comparison with the control group and for all the groups of the study. The pollutants have an effect upon the average number of enzyme in the blood serum. There is a significant increase in the average of the enzymes that carry amino (ALT, AST) an enzyme phosphate in comparison with the control group. The study has also shown a significant increase in the Monoaldehyde level MDA and decrease in the glutathione level, under the effect of various pollutants. It is noticed that the blood components as well as the biochemical variable are greatly affected as the period of exposure extended and these biochemical variables become very great. Therefore, most of the differences are existed in the third group whose ages range between (40 and 49) with 9 years of work, followed by the second group whose ages range between (30 and 39) with 7 years of work. Then comes the first group whose ages range between (20 and 29) with 5 years of work, in comparison with the control group
