The Jazmurian basin in Iran is an area affected by climate change and desertification where aerosols and dust storms are common. The aim of this work was to determine the human and ecological risks from atmospheric particles during dust storms in different cities in the Jazmurian basin. For this purpose, the dust samples were collected from Jiroft, Roodbar Jonoob, Ghaleh Ganj, Kahnooj and Iranshahr cities, which are located around the Jazmurian playa in southeast of Iran. Satellite-based Moderate Resolution Imaging Spectroradiometer (MODIS) aerosol products and the Aerosol Optical Depth (AOD) were used to detect aerosol loading in the atmosphere. Moreover, the trace element composition of the collected particles was determined and used to evaluate human and ecological impact assessment using US EPA human health risk assessment and ReCiPe 2016 endpoint hierarchist impact assessment method incorporated in the OpenLCA 1.10.3 software. The human health risk assessment of the particles revealed high non-carcinogenic risks for children from exposure to nickel and manganese and carcinogenic risks in both adults and children due to hexavalent chromium, arsenic and cobalt during dust storm events. Terrestrial ecotoxicity was found to have the largest ecological impact on ecosystems with copper, nickel and zinc exhibiting the largest contributions.
伊朗的杰祖尔盆地是一个受气候变化和荒漠化影响的地区，气溶胶和沙尘暴很常见。这项工作的目的是确定在杰祖尔盆地不同城市的沙尘暴期间大气颗粒物对人类和生态的风险。为此，从位于伊朗东南部杰祖尔潟湖周围的吉尔福特、鲁德巴尔琼努卜、加勒甘杰、卡霍诺杰和伊兰沙赫尔市采集了尘埃样本。利用基于卫星的中分辨率成像光谱仪 (MODIS) 气溶胶产品和气溶胶光学深度 (AOD) 来检测大气中的气溶胶负荷。此外，还测定了收集到的颗粒的微量元素组成，并利用美国环保署人类健康风险评估和包含在 OpenLCA 1.10.3 软件中的 ReCiPe 2016 终点等级评估方法来评估人类和生态影响评估。颗粒的人类健康风险评估表明，在沙尘暴事件期间，儿童因接触镍和锰而面临高非致癌风险，而成年人和儿童因六价铬、砷和钴而面临致癌风险。陆地生态毒性被发现对生态系统具有最大的生态影响，其中铜、镍和锌的贡献最大。
