Dusty storms considerably increase airborne particles in dry and semi-dry locations, such as deserts with no plants and strong winds. Therefore, the environment and people are affected severely. Ahvaz, an important metropolis, is often polluted by neighboring nations. The present research studies the concentration, source, and calculation of these particles' effects.
For health consequences evaluation, the WHO suggests the Air Quality Health Impact Evaluation Programmed (Air Q 2.2.3). Khuzestan Meteorology Office recorded particulate matter measurements on both hazy and clear days. The data was gathered voluminously in 2023.
According to data collected from Khuzestan province's meteorology documents, 49 days in 2023 had very unsafe air quality. The most polluted months in terms of the number of dust days are as follows: January (14 days) > December (12 days) > November (11 days) > August (5 days) > May (3 days) > September (2 days) > March, February, June, July, October (1 day) > April (0 days). HYSPLIT maps indicate that Iran causes dust in March, the Great Arabian Desert in December and August, Iraq in April, September, and October, Kuwait in January, Turkey in February and July, Egypt in June and May, and Oman in November.
The meteorology database reveals that Ahvaz is highly polluted and that 49 days had unacceptable dust levels. Based on assessments obtained employing the Air Q+ programs, the people of Ahvaz encountered heart disease, respiratory disease, and stroke caused by their exposure to PM particulates.
沙尘暴会大幅增加干旱和半干旱地区空气中的颗粒物，比如在没有植被且多风的沙漠地区。因此，环境和人类受到严重影响。阿瓦士是一座重要的大都市，常受到邻国的污染。本研究旨在探讨这些颗粒物的浓度、来源及其影响的计算方法。
为评估对健康的影响，世界卫生组织建议采用空气质量健康影响评估程序（Air Q 2.2.3）。胡齐斯坦气象办公室记录了雾霾天和晴天的颗粒物测量数据。这些数据在2023年大量收集。
根据从胡齐斯坦省气象文件收集的数据，2023年有49天空气质量非常不安全。就沙尘天数而言，污染最严重的月份如下：1月（14天）＞12月（12天）＞11月（11天）＞8月（5天）＞5月（3天）＞9月（2天）＞3月、2月、6月、7月、10月（1天）＞4月（0天）。HYSPLIT地图显示，3月的沙尘来自伊朗，12月和8月来自阿拉伯大沙漠，4月、9月和10月来自伊拉克，1月来自科威特，2月和7月来自土耳其，6月和5月来自埃及，11月来自阿曼。
气象数据库显示，阿瓦士污染严重，有49天的沙尘水平不可接受。根据使用Air Q+程序获得的评估结果，阿瓦士居民因接触PM颗粒物而面临心脏病、呼吸系统疾病和中风等问题。
