ترجمة الملخص

A result of increased human impact negatively on the environment and the nature of climatic conditions and the growing proportion of desertification and the number of days of dusty and contain the dust on a high proportion of various pollutants by industrial development, social and as a result of increasing the number of vehicles and its impact on human, animal and plant. we have conducted this research. Perform this search by selecting six sites within and on the outskirts of Deir Al-Zour and identification of species studied where and recorded six readings for each of the dust accumulated on the surface of the soil and dust accumulated on the leaves of trees and measured leaf area, as well as concentrations of lead and cadmium in the dust accumulated on the soil and leaves and within the plant tissue and examined the impact of dust on the leaves, from the date of 1/10/2007 until 5/15/2008 and conducted weekly readings are then calculated average per month and a half ,and taking into account the number of modes of transport as well as conservation and climatic data .Observed increase in the number of mechanisms recorded in the province during 2007 and 2008,has been shown that there is a rise in the number of transport modes operating on gasoline, compared with counterparts that run on diesel. As explained in the study of climate and a closely positive between temperature and wind speed, and not linked to the number of sandstorms, temperature and wind speed, and that there was a positive correlation between the number of dust storms and high temperatures and wind speed, that an increase in temperature or wind speed affect the some what increased high number of dust storms (as well as the command for the decrease).The results showed through statistical analysis using LSD least significant difference that: the amount of dust accumulated on the surface of soil (g) in Central Park is the highest ,as differentiated a moral from the arena of the President and the nursery and Ayyash ,but did not differentiate significantly improve on the site Albgelip and dizziness Mudallji. The study showed that the amount of dust accumulated on the leaves of cypress is the highest .The concentration of chlorophyll (a) in the leaves was the highest level recorded in my nursery and Ayyash, but these sites do not Eetmaizan are significant only to Central Park. As for the trees was in the lowest level of cypress and pine. While the concentration of chlorophyll (b) was at all locations is higher than Central Park,but there is no significant difference between the sites studied and trees in it. As for the concentration of chlorophyll total ,the Central Park, down on all sites,but there is no significant difference between those sites, The concentration of total chlorophyll in the leaves fallen cypress. The highest concentration of lead (ppm) in the dust accumulated on the surface of the soil at the site of Ayyash. As it turns out there is no significant difference between all sites and among species studied for the concentration of lead in the papers ,and found significant differences among the signatories to the President Square and Central Park for my Ayash and Albgelip concentration of lead in dust accumulated on the leaves. Sites do not differ much in the concentration of cadmium (ppm) in the dust accumulated on the surface of soil. Sites that contain leaf trees the highest concentration of cadmium is Albgelip and dizziness Mudallji President and yard,as there was no significant difference in the concentration of cadmium in the leaves. Except that the highest concentrations were found at the site of vertigo Mudallji. The same applies to differ between species because some of them are significant in the concentration of cadmium in the dust accumulated on the leaves.
