In Iran's biggest towns, deaths and hospitalizations from respiratory and cardiovascular diseases have a strong association with PM pollution concentrations. The WHO recommends assessing the health impacts using the Air Quality and Health Evaluation approach (Air Q 2.2.3). Data of particulates on both clear, dusty days have been provided by the Meteorology Office for Lorestan. Results indicated that in terms of mean AQI, May (162.46), July (121.7), and April (110.23) are the most polluted months in Poldokhtar city in 2022. May (16 days), July (6 days), March (5 days), and April (4 days) are the most contaminated months of the total number of polluted days. The days having the highest amounts of pollution in terms of the daily mean AQI are May 17th (407), April 10th (402), May 24th (393), July 31st (351), and April 18th (341). The maps extracted from HYSPLIT showed that the origin of the dust entering the city of Poldokhtar is the arid and semi-arid regions of Saudi Arabia, Egypt, Kuwait, and Turkey. May shows the maximum amount of pollution in comparison to other months, as shown by the mean AQI of 162.46. Furthermore, with an AQI score of 407 on May 17, it is assumed to be the most polluted day of the year. Hospitalized people who had respiratory diseases were most severely impacted by the short-term adverse effects of fine dust inhalation.
在伊朗的各大城镇，呼吸道和心血管疾病导致的死亡及住院情况与颗粒物污染浓度密切相关。世界卫生组织建议采用空气质量与健康评估方法（Air Q 2.2.3）来评估健康影响。洛雷斯坦省气象部门提供了晴朗和沙尘天气下的颗粒物数据。结果表明，就平均空气质量指数而言，2022年波尔 Dokhtar 市污染最严重的月份是五月（162.46）、七月（121.7）和四月（110.23）。在污染天数总数方面，五月（16天）、七月（6天）、三月（5天）和四月（4天）是污染最严重的月份。按日平均空气质量指数计算，污染最严重的日子分别是5月17日（407）、4月10日（402）、5月24日（393）、7月31日（351）和4月18日（341）。从HYSPLIT提取的地图显示，进入波尔 Dokhtar 市的沙尘来源是沙特阿拉伯、埃及、科威特和土耳其的干旱和半干旱地区。与其他月份相比，五月的污染程度最高，平均空气质量指数为162.46。此外，5月17日的空气质量指数为407，被认为是该年污染最严重的一天。吸入细颗粒物的短期不良影响对患有呼吸道疾病的住院患者影响最为严重。
