Problems caused by climate change are one of the most important environmental crises and threats of human society, especially in urban environments. In the city of Tabriz and in recent years, due to the growth of the population, a lot of migration from other cities, traffic, the development of industries and production centers have caused an increase in the production and distribution of pollutants. Based on this, in this research, attention has been paid to the evaluation of the quality of dust occurrence in the years 2019 and 2018. The concentration of dust particles in different areas of the studied places varies depending on the geographical location, topographical, climatic conditions and also their origin, both internal and external. Based on the results obtained from the analysis of laboratory results and field studies, in the Tabriz region and during the research period, the concentration of lead metal in dust is moderate for adults and severe for children, and the risk of mercury metal for both the elderly and children. It has been intense. The adverse effects of cadmium metal have been very severe in children and adults. On the other hand, the high air temperature in the city center and the formation of thermal islands in it causes local winds from the suburbs to the city center. With the transfer of pollution from the suburbs to the city center by these winds, the pollution situation in the city center also increases.

One of the important pillars of sustainable rural development is attention to environmental health and pollution-free. The aim of this study is to identify environmental pollutants and their impact on the health of rural residents in Kurdistan province in mountainous and foothill areas. Descriptive-analytical analysis method in which 6 major pollution variables of natural and human origin were identified. 3 natural variables. Including temperature, dusty days, local wind, in human dimensions, 3 variables, lack of planning in locating landfills, lack of investment in safe water supply and lack of design and architecture compatible with climate are important factors in environmental pollution. Rural biology identified.The results showed that one of the factors threatening the health and well-being of rural residents in the interior of houses is due to the production of incomplete methane and monoxide produced by animal waste at the rate of 25-30 ppm in 10 hours. But in the rural environment, dust, regional and local winds, high temperatures in summer and the release of livestock waste in the rural environment, which leads to the production of various insects and vermin. The combination of these factors is considered as the most important environmental pollutants and a threat to the health of rural people.
