This study aims to determine the health risks from some potentially toxic metal content of PM10 on the residents of Hamadan, Iran. The mean concentration of PM10 is 122.55 µg m–3, and for Pb, Cd, and Cr it is 7.44, 1.78, and 2.72 ng m–3, respectively. PM10 levels of 22% of the samples are higher than the National Ambient Air Quality Standards (NAAQS). Pb and Cd levels are within the standard/guideline limits, whereas Cr levels exceed the guideline value in 53% of the samples. Health risks from toxic elements of PM10 are estimated using hazard quotient (HQ) and hazard index (HI), and the cancer risk is evaluated based on lifetime daily cancer risk (CR). Both HQ and HI are <1; furthermore, children are at an increased health risk according to obtained HQ and HI values. Cr and Cd present potentially carcinogenic health risks, while CR from Pb is within the acceptable limits. Although both HQ and HI are obtained <1, conducting such health risk assessment studies really is needed to determine the air quality in different cities such as Hamadan and the obtained data can be used as general guidance for decision makers to manage the air quality.

伊朗哈马丹的 PM10 浓度、潜在有毒金属含量和人类健康风险评估

本研究旨在确定 PM 10 的某些潜在有毒金属含量对伊朗哈马丹居民的健康风险。PM 10的平均浓度为 122.55 µg m –3,而 Pb、Cd 和 Cr的平均浓度分别为 7.44、1.78和 2.72 ng m –3。22% 样本的PM 10水平高于国家环境空气质量标准 (NAAQS)。Pb 和 Cd 水平在标准/指导限值内,而 53% 的样品中 Cr 水平超过指导值。PM 10有毒元素的健康风险使用危险商数 (HQ) 和危险指数 (HI) 估计癌症风险,并根据终生每日癌症风险 (CR) 评估癌症风险。HQ 和 HI 均 <1;此外,根据获得的 HQ 和 HI 值,儿童面临更高的健康风险。Cr 和 Cd 存在潜在的致癌健康风险,而 Pb 的 CR 在可接受的范围内。尽管 HQ 和 HI 都<1,但确实需要进行此类健康风险评估研究以确定不同城市(如哈马丹)的空气质量,并且获得的数据可用作决策者管理空气质量的一般指导。
