Abstract

This study aimed to measure the concentration of the total suspended particle (TSP) and gaseous pollutants (CO, CO2, SO2 and NO2) that emitted from Nahrawan’s brick factories and compare it to its counterparts from the village of Nahrawan. Samples from 17 sites, as well as Nahrawan village were collected in the current study. The results showed that TSP had the highest concentration (9801.7 μg/m3), exceeding world health organization (WHO) standard in all study sites, including Nahrawan village. The results also indicated that CO concentration at most sites exceeded WHO standard. The results showed that CO2 concentration in all the sites exceeded WHO standard (250 ppm), while the measure taken from Nahrawan village registered lower. SO2 was not record in air of Nahrawan village, yet it formed the highest concentration (0.1 ppm) in the study area, much greater than the WHO standard (0.01 ppm). On the other hand, NO2 assumed the highest concentration of (0.3 ppm) again, higher than WHO standard of (0.11 ppm) across all sites, except Nahrawan village. Spatial analysis was performed to generate spatial patterns of air pollutants released by bricks factories in Nahrawan region and to represent the values of wind speed. Visualization of the spatial patterns revealed that the pollutants highly concentrated in the central and southern study area and is located towards the prevailing wind.

Abstract

For decades, human health was threaten (especially that of children) by what considered as a potential sources of lead exposure which are: lead-contaminated water, soil, and air. The proposed of the research involve developing an integrated exposure, uptake, and biokinetic (IEUBK) model as a human health risk model to predict the blood lead levels BLL in children. The data set of this project for human health risk posed by Pb contamination in air, water and soil were obtained from previous study achieved in 2014 which carried out on 108 school children (School children in rural areas (n=76 child) and School children in urban areas (n=32child) matched for age. The environmental samples demonstrated that the concentration of lead for air and soil exceeded the international acceptable threshold values. However, the concentration of lead in water was below the threshold value. The BLL value from currently result of IEUBK model was above the agency’s threshold of concern, 10 μg/dL which was documented as children’s BLL lowest level of concern. This predicted values result of BLL was in agreement with actual value of BLL in blood samples of school children for the chosen study. Also, the results of this research confirmed that the high BLL could be attributed to the high lead level in both air and soil of contaminate environment.

Abstract

The studies conducted by the Center for the Study of War in New York gave firmly evidence beyond doubt, is that the dust particles, which gathered in the desert of Kuwait and Iraq have a link to what happened to members of the military forces of disorder in the nerves and appeared to them of the symptoms of cancer and disorders of the respiratory system and heart disease. The dust particles (sand) in Kuwait and Iraq contain toxic substances, which dates back to the pollution caused by military equipment and dismantle the desert sands and turn it into light dust.The aim of this research to determination some toxic and carcenoginc elements such as (Pb, Co, Ni, Cu, Zn, Fe and Cd) in dust and soil in Baghdad city and their health effects types of resulting diseases. Samples were collected from airborne stations in the study area during the dusty days, also accompanied the process modeling dust collecting surface soil samples for the same selected sites in the city of Baghdad, and then the analysis is performed for the purpose of determining the concentrations of toxic and carcinogenic elements and compare it with the global determinants.Search Results showed that there is a large increase Total suspended particles (TSP) concentrations in all sites compared with allowable limits, where the highest concentration in the Al-Ealam site (2241.37μg/m3), and the lowest was in the Al-ameryah site (1096.04 μg/m3) which is much higher than the permissible limits. It also found that most concentrations of chemical toxic elements in the dust did not exceed the permissible limits, except concentrations of zinc and iron has exceeded the permissible limits, where the highest concentration of zinc in the highway New Baghdad – AlDorah (10.63ppm) is higher than the permissible limits. The highest concentration of iron in Al-Jadiryah (ministry of science and technology) (8.56ppm). Through the research found that dust storms and strong winds blowing in the soil is an important factor in the increase TSP and some toxic elements concentrations in the air, and the movement of vehicles can play an important role in increasing concentrations of TSP in the atmosphere as a result of movement that lead to volatility dust, as well as the TSP emitted from car exhausts, in addition to Industrial Activities especially brick factories and power plants, which could affect the concentrations of these elements in the soil of same selected sites. The results also show that most concentrations of heavy metals in the soil of the selected sites did not exceed the permissible limits except zinc and nickel, has reached the highest concentration of zinc in the Al-Amiryah and Al-Ealam sites the highest of the standards limits, and is due to the effect of divorced some industrial activities and the impact of some divorced vehicles and others.The dust storms and dust by different sources have a significant impact on health and this depends on two components degree and duration of exposure to the dust atoms airborne and are more pronounced on the inhabitants of the desert areas and rural ones who were more susceptible to (lung desert), while those who live in cities they are more susceptible to recurrent bouts of sensitivity generally infect the body and eye, nose and chest in particular.

ان الدراسات التي اجراها مركز دراسات الحرب في نيويورك اعطت دليلا جازما لا يقبل الشك، وهو ان ذرات الغبار والتي تجمعت في صحراء الكويت والعراق لها ارتباط بما حدث لأفراد القوات العسكرية من اضطرابات في الأعصاب وما ظهر عليهم من أعراض السرطانات والاعتلالات في الجهاز التنفسي وأمراض القلب.ان ذرات الغبار (الرمال) في الكويت والعراق تحتوي على المواد السامة والذي يعود الى التلوث الذي أحدثته المعدات العسكرية وتفكيكها لرمال الصحراء وتحويلها الى غبار خفيف. يهدف البحث الى تحديد تراكيز بعض العناصر السامة والمسرطنة (Zn, Cu, Mn, Ni, Co, Pb, Cd,Fe) في الغبار والتربة في مدينة بغداد وتحديد تاثيراتها الصحية وانواع الامراض الناتجة عنها.تم جمع نماذج من الدقائق العالقة في الهواء في منطقة الدراسة خلال فترة الايام المغبرة، كذلك رافقت عملية نمذجة الغبار جمع عينات من التربة السطحية لنفس المواقع المختارة في مدينة بغداد. ومن ثم اجريت التحاليل لغرض تحديد تراكيز العناصر السامة والمسرطنة ومقارنتها مع المحددات العالمية.بينت نتائج البحث ان هناك ارتفاع كبير في تراكيز الدقائق العالقة مقارنة بالحدود المسموح بها، حيث بلغ اعلى تركيز في منطقة الاعلام (2241.37µg/m3)، اما ادنى تركيز فكان في منطقة (1096.04µg/m3) وهي اعلى بكثير من الحدود المسموح بها. كما وجد ان معظم تراكيز العناصر الكيمياوية السامة في الغبار لم تتجاوز الحدود المسموح بها، عدا تراكيز عنصري الزنك والحديد فقد تجاوزت الحدود المسموح بها، حيث بلغ اعلى تركيز لعنصر الزنك في موقع طريق السريع بغداد الجديدة-الدورة(10.63ppm) وهي اعلى من الحدود المسموح بها، بينما بلغ اعلى تركيز للحديد في منطقة الجادرية (وزارة العلوم والتكنولوجيا) (8.56ppm). من خلال البحث وجد ان العواصف الترابية والرياح القوية التي تهب على التربة عامل مهم في زيادة تراكيز الدقائق العالقة وبعض العناصر السامة في الجو. وان حركة المركبات يمكن ان تلعب دوراً مهماً في زيادة تراكيز الدقائق العالقة في الجو نتيجة حركتها التي تؤدي الى تطاير الغبار وكذلك الدقائق المنبعثة من عوادم السيارات، اضافة الى الفعاليات الصناعية خصوصا معامل الطابوق ومحطات توليد الطاقة الكهربائية والتي يمكن ان تؤثر على تراكيز هذه العناصر في تربة نفس المواقع المختارة. كما بينت النتائج ان معظم تراكيز العناصر الثقيلة في تربة المواقع المختارة لم تتجاوز الحدود المسموح بها عدا عنصري الزنك والنيكل خصوصا في منطقتي العامرية والاعلام وهي اعلى من الحدود المسموح بها، ويعود سبب ذلك الى تاثير مطلقات بعض الفعاليات الصناعية وتاثير بعض مطلقات المركبات وغيرها. ان العواصف الترابية والغبار المتطاير بفعل المصادر المختلفة لها تأثيرات واضحة على الصحة وهذه تعتمد على عنصرين هما درجة ومدة التعرض لذرات التراب المحمول في الهواء والتي تكون اشد وضوحا على ساكني المناطق الصحراوية والقروية منها والذين يكونوا أكثر عرضة للإصابة بـ(الرئة الصحراوية)، أما الذين يعيشون في المدن فهم أكثر عرضة للإصابة بنوبات متكررة من حساسية تصيب الجسم عموما والعين والأنف و الصدر خصوصا.
