تمّت في هذا البحث دراسة تأثير تلوث الهواء الملوث في العناصر التشخيصية والصفات المورفولوجية لأوراق نبات الدفلةNerium olender المزروعة على أطراف الشوارع في مدينة اللاذقية. إذ أخذت العينات من منطقتين مختلفتين من حيث شدّة التلوث، وذلك خلال الفترة الواقعة ما بين تشرين الأول من عام 2012م ولغاية أيلول من عام 2013م . المنطقة الأولى (شارع الجمهورية في مدينة اللاذقية): وهي منطقة شديدة التلوث إذ تزداد فيها الحركة المرورية للسيارات والباصات والشاحنات . المنطقة الثانية ( حديقة جامعة تشرين ) : وهي أقل تلوثاً وذات حركة مرورية ضعيفة . بينّت لنا النتائج التي حصلنا عليها أنه كلما ازدادت الحركة أو الكثافة المرورية نقص وزن الورقة وطولها وتغيّر لونها، وهذا بدوره يؤثر في عدد وحجم وشكل العناصر التشخيصية التي تلعب دوراً في تمييز الأنواع النباتية عن بعضها البعض .
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 .

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.
