In this study, honeybees were used to determine spatio-temporal variations and origin sources of Pb. Lead concentrations and isotopic composition were used in combination with selected statistical methods. The sampling was carried out at five different locations in Serbia: urban region (BG), petrochemical industry (PA), suburban region (PV), rural region (MS) and thermal power plant region (TPP) during 2014. At PA and PV locations, samples were taken during multiple years. This is the first use of Kohonen self-organizing map (SOM) in combination with honeybees as bioindicators to determine spatio-temporal variations and origin of Pb pollution. It was observed that during the years Pb concentrations were in decline. Anthropogenic sources are most dominant in BG and TPP, in PA there are mixed sources of natural and anthropogenic origin and in PV Pb is of natural origin. It can be concluded that honeybees in combination with SOM can be used to differentiate between slight changes in spatio-temporal variations of Pb, as well as for source appointment.
在这项研究中，使用蜜蜂来确定 Pb 的时空变化和来源。采用铅浓度和同位素组成结合选定的统计方法进行采样。在塞尔维亚的五个不同地点进行了采样：城市地区（BG）、石化工业区（PA）、郊区（PV）、农村地区（MS）和热电厂区（TPP），采样时间为 2014 年。在 PA 和 PV 两个地点，多年来都有采样。这是首次将科荷伦自组织映射（SOM）与蜜蜂作为生物标志物结合使用，以确定 Pb 污染的时空变化和来源。结果表明，多年来 Pb 浓度呈下降趋势。人为来源在 BG 和 TPP 中最为突出，在 PA 存在自然和人为混合来源，而在 PV，Pb 则来自自然来源。可以得出结论，蜜蜂与 SOM 相结合可用于区分 Pb 时空变化的细微差异，以及源分配。
