The ability of honeybees to collect particulate matter (PM) on their bodies makes them outstanding bioindicators. In this study, two cities, Pančevo (PA) and Vršac (VS), South Banat district, Vojvodina, Serbia, were covered with two sampling sites each. The aims of this study were to determine concentrations of Al, Ba, Cd, Co, Cr, Cu, Fe, Mn, Na, Ni, Sr, and Zn in the bodies of honeybees during July and September of 2013, 2014, and 2015 and to analyze their spatial and temporal variations and sources of analyzed elements, as well as to assess pollution levels in the two cities. Significant temporal differences were found for Al, Ba, Cd, Co, Cr, Cu, Fe, Mn, Na, Ni, and Zn. Trend of reduction in metal concentrations in bodies of honeybees during the years was observed. Statistically significant spatial variations were observed for Al, Ba, and Sr, with higher concentrations in VS. PCA and CA analyses were used for the first time to assess sources of metals found in honeybees. These analyses showed two sources of metals. Co, Cd, Na, Fe, Mn, Zn, and partly Cu were contributed to anthropogenic sources, while Ca, Al, Mg, Cr, Ba, Sr, and Ni were contributed to natural sources.
蜜蜂能够在身体上收集颗粒物（PM），这使它们成为出色的生物指标。在这项研究中，塞尔维亚伏伊伏丁那州南巴纳特地区的潘切沃（PA）和弗尔沙茨（VS）两个城市每个城市都设有两个采样点。本研究的目的是在 2013 年、2014 年和 2015 年 7 月和 9 月期间确定蜜蜂体内的 Al、Ba、Cd、Co、Cr、Cu、Fe、Mn、Na、Ni、Sr 和 Zn 的浓度，并分析其时空变化和分析元素的来源，以及评估两个城市的污染水平。发现 Al、Ba、Cd、Co、Cr、Cu、Fe、Mn、Na、Ni 和 Zn 存在显著的时间差异。观察到蜜蜂体内金属浓度在这几年中呈下降趋势。Al、Ba 和 Sr 存在显著的空间差异，VS 中的浓度更高。首次使用 PCA 和 CA 分析来评估蜜蜂体内金属的来源。这些分析表明存在两个金属源。Co、Cd、Na、Fe、Mn、Zn 和部分 Cu 归因于人为来源，而 Ca、Al、Mg、Cr、Ba、Sr 和 Ni 归因于自然来源。
