This study has conducted to investigate the effect of air pollution on diagnostic elements and morphologicl characters of leaves of Neruim oleander Cultivated in roadsides in Lattakia City . Samples were collected from tow sites differ in pollution inteusity between october 2012 and september 2013 . The first site ( Al Jmhoria street in Lattakia city ) was more polluted and has more traffic activity . Whil the second site ( tishreen University park ) Was Less polluted and less traffic activity . The results have showed that the length , the weight and the colour of the leaf are negtively incieased because of traffic intensity and this , inturn , affects the shape , the size and the number of diagnostic elements which play animportant rule in differentation the species from each other .

Research summary
تتناول هذه الدراسة تأثير تلوث الهواء الناتج عن عوادم السيارات على العناصر التشخيصية والصفات المورفولوجية لأوراق نبات الدفلة (Nerium oleander) المزروعة على أطراف الشوارع في مدينة اللاذقية. تم جمع العينات من منطقتين مختلفتين من حيث شدة التلوث: شارع الجمهورية (منطقة شديدة التلوث) وحديقة جامعة تشرين (منطقة أقل تلوثاً). أظهرت النتائج أن زيادة الحركة المرورية تؤدي إلى نقصان وزن وطول الأوراق وتغير لونها، مما يؤثر على عدد وحجم وشكل العناصر التشخيصية للنبات. تم استخدام أدوات مثل الفرن الكهربائي والمجهر الضوئي لتحليل العينات. النتائج أوضحت أن الأوراق في المنطقة الأكثر تلوثاً كانت أقل عدداً، أصغر حجماً، وشاحبة اللون، بينما كانت الأوراق في المنطقة الأقل تلوثاً أكثر نضارة واخضراراً. توصي الدراسة بضرورة المحافظة على نظافة البيئة ومتابعة الأبحاث في هذا المجال.
Critical review
تعتبر هذه الدراسة مهمة جداً في تسليط الضوء على تأثير تلوث الهواء على النباتات، خاصة في المناطق الحضرية. ومع ذلك، يمكن أن تكون الدراسة أكثر شمولاً إذا تضمنت تحليلاً كيميائياً مفصلاً للملوثات الموجودة في الهواء وتأثيرها على التفاعلات الكيميائية داخل أوراق النبات. كما يمكن أن تكون النتائج أكثر دقة إذا تم استخدام تقنيات تحليلية متقدمة مثل التحليل الطيفي. بالإضافة إلى ذلك، يمكن أن تكون الدراسة أكثر فائدة إذا تم توسيع نطاقها ليشمل أنواع نباتية أخرى لمقارنة تأثير التلوث عليها.
Questions related to the research
  1. ما هي المناطق التي تم جمع العينات منها في الدراسة؟

    تم جمع العينات من منطقتين: شارع الجمهورية (منطقة شديدة التلوث) وحديقة جامعة تشرين (منطقة أقل تلوثاً).

  2. ما هي الأدوات المستخدمة في تحليل العينات؟

    تم استخدام فرن كهربائي لتجفيف الأوراق، طاحونة كهربائية لسحق الأوراق، ومجهر ضوئي لفحص العناصر التشخيصية.

  3. ما هو التأثير الرئيسي لتلوث الهواء على أوراق نبات الدفلة؟

    التلوث يؤدي إلى نقصان وزن وطول الأوراق وتغير لونها، مما يؤثر على عدد وحجم وشكل العناصر التشخيصية.

  4. ما هي التوصيات التي قدمتها الدراسة؟

    أوصت الدراسة بضرورة المحافظة على نظافة البيئة، متابعة الأبحاث في هذا المجال، وتوفير الإمكانات اللازمة للبحث العلمي.

The research was conducted to study the resistance of Nerium plant which are planting on sides of roads and the cities portals. The research was performed by studying the leaves of Nerium plant, through studying the length and weigh of the leaf, an d its area and water content. In addition to studying the wools and hiatus and chlorophyll concentration, and compared the results between the polluted region which is the entry of Banias City, and the control one which is the gardens of Tishreen University. Results showed non significant reduction in length, weight and area of the leaf in the polluted region compared with the control one. It attained (16.2 cm, 0.97 g and 26.3 cm2), respectively in the polluted region. Where it was (17.8 cm, 1.25 g and 27.7 cm2), for control region, respectively. Also, there was no significant differences in water content between the two studied regions. It attained respectively (52.2 and 53.9 %). Our results showed: - That a number of hiatus decreased, whereas the wools increased in the polluted region compared with control region insignificantly. The mean of a number of it was 12 in polluted region, compared with 14 in the control region. - A simple insignificant reduction in the concentration of chlorophyll A in polluted region compared with the control, where it attained (0.93 and 0.98), respectively. The Nerium oleander plant was resistance and tolerance to the air pollution.
This research aims to predict the level of air pollution with a set of data used to make predictions through them and to obtain the best prediction using several models and compare them and find the appropriate solution.
The study aimed to clarify the economic concept to the problem of environmental pollution and the economic effects of him. How is the confrontation of this economic problem through the following steps: 1- Quantification of environmental pollution (air quality monitoring in the surrounding medium). 2- Quantification of the results of environmental pollution (the negative impact on health and property due to air pollution , and loss of agricultural and animal wealth . 3- Estimate of the results of environmental pollution ( the cost of treatment and alternative employment opportunities , loss of GDP as a result of the inability to work due to illness or disability or early death , property damage costs in agricultural and animal wealth , the cost of damage in the aesthetic value . The study concluded that a range of results, including :  Monitoring and Pollution reality in Banias , and then compare the average cost incurred by the population as a result of ( health damage , property damage, damage in agricultural and animal wealth ).  Determination of environmental costs through the expense of a decline in the quality of people's lives and the deterioration of the quality of the environment , such as exposure to diseases caused by environmental pollution and the cost of treating these diseases physically and years of work and life that are lost due to disease , in addition to the loss of the value of environmental services and resources, especially non-renewable ones, as well as the loss opportunities and environmental features such as the aesthetic standards of the tourist areas . The study recommended that the industrial strategies in Syria adopt Sustainable Industrial Development Policy, which include an integrated and comprehensive environmental dimension in the administration of any industrial development project . This is in line with the concept of sustainable development, which calls for enterprises of different types to preserve the assets and resources of the community of human, material and environmental which is considered the property of the current and future generations.
We discussed the importance of studying the trichomes award in olive trees, leaves and its role in the resistance to these trees against pollution resulting from the Banias refinery intake, through the study of their density and distribution on a superficial paper and examine the concentration of chlorophyll in the leaves, and comparing the results between the contaminated areas and the control area . Results showed that the density of the trichomes play a role in protecting the ports of entry into force of pollutants into the plant tissue, and its impact on the pigments of photosynthesis, and thus the process of photosynthesis.
Cultivars of Medicago Sativa l.var local were planted in three locations, ten pots per location. The first location wich is the most polluted one is (Bab Toma), second polluted one is (Jeser Victoria), and the reference location is (Daria), in the west of Damascus. Temperature, relative humidity and concentrations of main pollutants in that three locations were measured. Resultes showed that air pollution decreased growth of plants, amount of chlorophyll, production of plants, number of flowers, number of pods and leaf area in comparison with reference location.
