Morbidity and mortality impacts of particulate matter (PM) are globally important health critical parameters. In this ecological-descriptive study, the health impact of PM₁₀ and PM_2.5 associated with there temporal variations in Dezful city were assessed from 2013 to 2015. AirQ+ software handles the PM air pollutants by addressing impact evaluation and life table evaluation. We used a new method to analysis fine particles feature by using regular daily observations of PM₁₀. In this method, relationship between PM_2.5 and PM₁₀ mass concentrations were analyzed and calculated. The annual average concentrations of PM₁₀ were 147.1, 114.3 and 158.8 μg/m³, and the annual average concentration of PM_2.5 were 57.8, 50.7 and 58.2 μg/m³ in 2013, 2014 and 2015, respectively. PM₁₀ also had obvious diurnal variations with highest hourly concentrations in 13:00 and 22:00 but the lowest concentrations often occurred in 05:00 and 16:00. Unexpectedly, in weekends the concentration of PM pollutants appeared to have increased from 18:00 to midnight. The daily based analysis showed that there are 147 dusty days in the study period during which the most severe dusty day occurred in 2014. Over the study period, mean levels of PM₁₀ and PM_2.5 in both conditions were higher in 2015 compare to 2013 and 2014, which probably is due to higher frequency of dust storms in 2015. Hence, during 2015 and 2013 they're were higher morbidity and mortality compare to 2014 due to exposure to higher polluted air with PMs in all cases except lung cancer (LC).

颗粒物 (PM) 对发病率和死亡率的影响是全球重要的健康关键参数。在这项生态描述性研究中，评估了 2013 年至 2015 年 Dezful 市 PM ₁₀和 PM _2.5与时间变化相关的健康影响。AirQ+ 软件通过影响评估和生命表评估来处理 PM 空气污染物。我们采用了一种新方法，通过每天定期观测 PM ₁₀来分析细颗粒物特征。该方法分析计算了PM _2.5和PM ₁₀质量浓度之间的关系。 2013年、2014年和2015年PM ₁₀年平均浓度分别为147.1、114.3和158.8 μg/m ³ ，PM _2.5年平均浓度分别为57.8、50.7和58.2 μg/m ³ 。 PM ₁₀也有明显的日变化，最高浓度出现在 13:00 和 22:00，但最低浓度往往出现在 05:00 和 16:00。出乎意料的是，周末PM污染物浓度从18:00到午夜似乎有所增加。逐日分析显示，研究期间共有 147 个沙尘日，其中最严重的沙尘日发生在 2014 年。在研究期间，2015 年两种情况下的 PM ₁₀和 PM _2.5平均水平均高于 2013 年， 2014 年，这可能是由于 2015 年沙尘暴频率较高。因此，与 2014 年相比，2015 年和 2013 年的发病率和死亡率更高，因为除了肺癌 (LC) 之外，所有病例都暴露在 PM 污染程度较高的空气中。
