An overview of the origin and geographical routing of fine dust and strategies to deal with it in Iran

Iran and the Middle East are in the dry belt of the world. Due to climatic and geographical conditions, our country is prone to dust storms. Drought, insecurity and war, lack of vegetation, atmospheric instability in neighboring deserts and horizontal and vertical transfer of dust particles and its intensification due to intrusion and occupation The practice has had adverse effects on the ecosystem, health, health, production, transportation, tourism, increased pollution, increased migration, and the like. This research intends to use the method of collecting library information and using data, maps and spatial and geographical analysis to get a proper knowledge and picture of the geographical status of the fine dust phenomenon in terms of origin and direction of its creation. Then, using this information, to analyze the space and find the root of the internal and external origin of fine dust. Therefore, in this article, with a review and descriptive method, the route and the dust center are first examined outside the country, such as Iraq, Syria and the Arabian Peninsula, and then the Northeast region, Central Asia, Turkmenistan and southeast Pakistan using The map and related zoning were collected and then the internal origin in the main geographical directions of the dust and dust phenomenon from the interior of the country was studied. This phenomenon occurs throughout the year, but the frequency of occurrence and its negative effect and worse air quality It is more common in hot seasons, especially in summer and July and August. This is due to the frequent influx of dust from Iraq and the instability of the Hijaz desert climate, declining air humidity, drought, excessive use of water and natural resources, increasing temperature and speed and wind direction, and drying of wetlands and mismanagement. Various in economic, social, political, environmental dimensions. There is an institution and organization that mentions some of these consequences and strategies to deal with it from the research results.
