It is well established that respiratory mortality and morbidity are associated with high concentrations of fine particles such as PM2.5. The aim of this study was to evaluate the long- and short-term impacts of PM2.5 on the population of Agadir, Morocco, using AirQ 2.1.1 software. The mean PM2.5 values were obtained from data collected at three sites. Baseline incidence data were obtained from the literature, and relative risk (RR) values were referenced from the World Health Organization. This study quantified long-term total mortality (LT-TM), lung cancer mortality (LT-LC), morbidity from acute lower respiratory tract infections (LT-ALRI), and morbidity from chronic obstructive pulmonary disease (LT-COPD), as well as short-term total mortality (ST-TM). The attributable proportions (AP) of LT-TM and LT-LC were estimated to 14.19% and 18.42%, respectively. Their excess deaths were estimated to 279 and 11 persons, respectively, and their RRs to 1.16 (95% CI: 1.10-1.22) and 1.23 (95% CI: 1.12-1.37), respectively. Furthermore, the AP of LT-ALRI and LT-COPD were estimated to 14.36% and 15.68%, respectively, their excess deaths to 33 and 4, and their RRs to 1.17 (95% CI: 1.11-1.31) and 1.19 (95% CI: 1.00-1.02), respectively. In comparison, the AP of ST-TM was estimated to 1.27%, with a 25-person excess death rate. This study was conducted to inform decision-making and to promote local policies on ambient air quality.
众所周知，呼吸死亡率和发病率与高浓度细颗粒物（如PM2.5）有关。本研究的目的是使用AirQ 2.1.1软件评估PM2.5对摩洛哥阿加迪尔人群的长期和短期影响。PM2.5的平均数值来自在三个地点收集的数据。基线发病率数据来自文献，相对风险（RR）值参考世界卫生组织。本研究对长期总死亡率（LT-TM）、肺癌死亡率（LT-LC）、急性下呼吸道感染发病率（LT-ALRI）、慢性阻塞性肺疾病发病率（LT-COPD）以及短期总死亡率（ST-TM）进行了量化。LT-TM和LT-LC的归因比例（AP）分别估计为14.19%和18.42%。它们的超额死亡人数分别估计为279人和11人，RR值分别为1.16（95%置信区间：1.10 - 1.22）和1.23（95%置信区间：1.12 - 1.37）。此外，LT-ALRI和LT-COPD的AP分别估计为14.36%和15.68%，它们的超额死亡人数分别为33人和4人，并分别为1.17（95%置信区间：1.11 - 1.31）和1.19（95%置信区间：1.00 - 1.02）。相比之下，ST-TM的AP估计为总死亡率估计为1.27%，超额死亡率为25人。开展本研究是为决策提供信息，并推动有关环境空气质量的地方政策。
