Abstract

The concentrations of eight heavy metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn) associated with PM_2.5 and PM₁₀ in Sarajevo air, Bosnia and Herzegovina (BiH) have been studied. A total of 136 PM_2.5 and PM₁₀ samples were simultaneously collected from 21 February to 11 November 2020. Metal contents were determined by atomic absorption spectrometry, flame (FAAS) and electrothermal (ETAAS) techniques. The mean concentrations of metals in PM₁₀ are 2.93 ng/m³ (Cd), 7.21 ng/m³ (Cr), 12.02 ng/m³ (Cu), 126 ng/m³ (Fe), 20.74 ng/m³ (Mn), 6.98 ng/m³ (Ni), 8.74 ng/m³ (Pb) and 128 ng/m³ (Zn). In PM_2.5 samples the mean concentrations of Cd, Cr, Cu, Fe, Mn, Ni and Zn are 0.39, 4.06, 2.26, 110, 0.63, 1.93 and 5.28 ng/m³, respectively. Pb was not detected in PM_2.5 samples. Strong correlation was obtained for metal pairs Mn-Cu in PM₁₀ and moderate for Ni-Fe in PM_2.5. The health risk assessment shows that the adult population of Sarajevo is at increased lifetime risk of experiencing cancer because of exposure to Cd concentrations in PM₁₀.

波斯尼亚和黑塞哥维那萨拉热窝空气中 PM2.5 和 PM10 重金属的健康风险评估。

研究了波斯尼亚和黑塞哥维那（波黑）萨拉热窝空气中与 PM2.5 和 PM10 相关的八种重金属（镉、铬、铜、铁、锰、镍、铅和锌）的浓度。从 2020 年 2 月 21 日至 11 月 11 日，共同时采集了 136 份 PM2.5 和 PM10 样本。采用原子吸收光谱法、火焰（FAAS）和电热（ETAAS）技术对金属含量进行了测定。PM10 中金属的平均浓度为 2.93 纳克/立方米（镉）、7.21 纳克/立方米（铬）、12.02 纳克/立方米（铜）、126 纳克/立方米（铁）、20.74 纳克/立方米（锰）、6.98 纳克/立方米（镍）、8.74 纳克/立方米（铅）和 128 纳克/立方米（锌）。在 PM2.5 样本中，镉、铬、铜、铁、锰、镍和锌的平均浓度分别为 0.39、4.06、2.26、110、0.63、1.93 和 5.28 纳克/立方米。在 PM2.5 样品中未检测到铅。PM10 中金属对 Mn-Cu 的相关性较强，PM2.5 中金属对 Ni-Fe 的相关性一般。健康风险评估结果表明，萨拉热窝的成年人一生中罹患癌症的风险因接触 PM10 中的镉浓度而增加。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
