PM pollution is one of the most important environmental problems worldwide. One of the sources of PM pollution, which has a negative impact on human health, is dust that enters the atmosphere, especially in arid regions. Iğdır Province, located in the east of Anatolia, has an arid climate character and was selected as the most polluted province in Europe in 2021 and 2022 (in terms of PM2.5 pollution). In this study, the effect of wind erosion-induced dust on air pollution in Iğdır province was investigated. We think that local wind erosion during the summer season (May–September) in the province is effective on PM pollution. Because there are no industrial activities, vehicular traffic, fuel consumption and volcanic activities that cause PM pollution in the summer season around Iğdır. On the other hand, Türkiye’s second largest wind erosion area and the other two wind erosion areas are located here, and dust storms are quite frequent. The causes of local wind erosion, which is one of the main factors in air pollution in the summer period, were investigated from a geographical perspective and various data sets were utilized. Then, wind erosion sites were examined and their regional distributions were indicated. Research findings on wind erosion sites were supported by remote sensing techniques (quartz index, aerosol density, etc.). All the data obtained support the idea that wind erosion is a dominant factor in the high level of PM pollution during the summer season in this area. Because the number of days with strong winds during this period is quite high and EU, WHO and national PM limit values are exceeded almost every day.

遥感支持分析风蚀对干旱地区局地空气污染的影响：以土耳其东部伊德尔省为例

PM 污染是全球最重要的环境问题之一。对人体健康产生负面影响的 PM 污染源之一是进入大气的灰尘，尤其是在干旱地区。伊德尔省位于安纳托利亚东部，气候干旱，被选为 2021 年和 2022 年欧洲污染最严重的省份（PM2.5 污染）。在这项研究中，调查了风蚀引起的沙尘对伊德尔省空气污染的影响。我们认为该省夏季（5-9 月）局部风蚀对 PM 污染有效。因为在 Iğdır 周围的夏季，没有工业活动、车辆交通、燃料消耗和火山活动导致 PM 污染。另一方面，土耳其第二大风蚀区和另外两个风蚀区都位于这里，沙尘暴相当频繁。局部风蚀是夏季空气污染的主要因素之一，从地理角度调查了局部风蚀的原因，并利用了各种数据集。然后，检查了风蚀地点并指出了它们的区域分布。风蚀地点的研究成果得到了遥感技术（石英指数、气溶胶密度等）的支持。所有获得的数据都支持这样一种观点，即风蚀是该地区夏季 PM 污染程度高的主要因素。因为这段时间的大风天数比较多，几乎每天都超过欧盟、世界卫生组织和国家的PM限值。
