Abstract:
Study of climate in Basrah and its impact on Asthma and other diseases of the respiratory system have revealed the following : - 1. Climate is the most effective factor in the study. Rise of temperature, increase of evaporation and the little humidity content in soil because of the little rainfall make it possible for the wind, particularly north and northwestly wind that is dominant in the area under study, to carry the decomposed particles of soil. This is particularly true in case of the alleviatory plain which constitutes a %50 of the area of the governorate. This area is characterized by being generally plain from the north to the south and that makes it easy for the wind to blow from it. These factors greatly affect the soil in many places in the governorate; especially its western part and the unused lands in the alleviatory plain because of lack of agriculture and of natural plants which protect soil. Because of all these reasons, dust increases in the area under study.2. Areas outside the range of the study have obvious effect on carrying the particles of soil from the surrounding governorates like Thi Qar and Muthana. Thi Qar, in particular, witnesses repeated dust storms. This, in turn, increases the amount of dust in the western part of the area under study. Most of the lands in these governorates are arid and dust coming from them dominates when northwestly wind blows. Dust may come from the deserts in the neighboring countries such as the Arab Peninsula, the great African desert, sham desert and Sinai. Increased iron in the dust of the area under study is brought by the dust storms coming from the neighboring countries to the governorate. These are also other factors that increase asthma and other diseases of sensitivity in the respiratory system.3. Dust increases in summer because of rise of temperature. Variation of temperature during the day leads to prevalence of dust. Also, currents that carry dust are made, more upwards and draw the dust particles from their sources. Therefore, dust prevails in the governorate is the afternoon when temperature is the highest during the day. 4. The water surface (marshes and swamps) in the eastern part of the governorate that occupy big area (3182 Km2) of the land during flood decrease the rate of asthma and other sensitivity diseases of the respiratory system in the towns and municipalities of the governorate such as Qurna and Mediana where these surfaces become places for settling dust and soil down. This is contrary to the case is the western part of the governorate where there are no such water surfaces. But, sometimes, these water surfaces have negative impact on the population in the governorate when temperature rises and humidity increases during summer and the weather becomes very tiring especially when the wind is still. The area under study is affected by the Arabian Gulf when the south easterly wind that is filled with humidity blows during summer. Because of this wind, patients of asthma, in particular, suffer repeated symptoms of the diseases.5. The rate of the diseases under study increases in the governorate in : a. Spring because of the existence of pollen and residue of the insecticide and fertilizers in air. b. Autumn in comparison to summer because of rising in temperature and increase of humidity in the atmosphere. c. Winter because of the low temperature and the high relative humidity.d. The many periods of heat rise in summer.6. Man contributed a lot to the increase of rate of diseases of the respiratory system in the area under study particularly after 1990. The year 1991 witnessed the highest rate of dust storms. Soil was very highly decomposed because of the movements of the explosives that were used, the different soil barriers that were made and man’s wrong practices in agriculture and grazing. Man, also, does not follow the appropriate means to stop sand dunes that reach many forms, factories and roads.7.Means of transportation in most areas of the governorate cause increase of still and moving dust because they are usually not good for movement and transportation. Any movement of these means causes dust. Besides, means of transportation release different dangerous pollutants that negatively affect the respiratory system.8. Petroleum refineries, electricity power stations, flour mills and ice factories are located near the population areas. This means that little care is given to the palming of the governorate. These establishments are also, reasons of such diseases. 9. Basrah, particularly recently, is exposed to dust because of the little green area in and around it. Construction processes reduce such areas that work to refresh and refine air. It is, therefore, very necessary to full the empty spaces with trees, to take care of private and public gardens and to clean roads and allocate specific places for gar bage. Besides, old wet houses in some places in the governorate contribute to increasing the diseases under study.10. Wet salty lands in Basrah governorate are considered as a type of desertification that pollutes air with salt and diminishes many lands that are fit for forming. 11. All the above mentioned reasons raise the number of patients of asthma and other sensitivity diseases of the respiratory system. The total number of such patients was during the time of the study as following : 85320 patients of sensitivity diseases and 119366 patients of asthma
