In recent years, honeybees and bee products such as pollen and honey have been used as bioindicators for monitoring environmental pollution. Unfortunately, there are few studies about polychlorinated biphenyl (PCB) concentrations in honeybees and bee products from Turkey. Honeybee and pollen samples were taken between May and September 2017, and honey samples were taken between July and September 2017 at urban and semi-urban areas in Bursa (Turkey). PCB concentrations measured by gas chromatography-microelectron capture detector (GC-μECD) were found to be 135.46 ± 6.53, 81.47 ± 23.52, and 106.35 ± 21.60 ng g dry weight (dw) for honeybee, pollen, and honey samples in the urban area, respectively; and 126.35 ± 26.54, 67.57 ± 27.34, and 118.88 ± 55.28 ng g dw for honeybee, pollen, and honey samples in the semi-urban area, respectively. Pearson correlation was made between meteorological parameters and pollutant concentrations. According to the correlation results, a significant relationship was found between the pollen and honey results and the total cloudiness and temperature in the semi-urban area. The coefficient of divergence (COD) and Pearson correlation coefficient (PCC) methods were applied to determine the similarities and differences between the pollutant concentrations and sources of the two areas and the temporal variation. According to these two methods, PCB concentrations and emission sources in honeybee and pollen samples in urban and semi-urban areas were generally different in May and June, and similar in August and September.
近年来，蜜蜂和蜂产品（如花粉和蜂蜜）已被用作监测环境污染的生物标志物。不幸的是，关于土耳其蜜蜂和蜂产品中多氯联苯（PCB）浓度的研究很少。2017 年 5 月至 9 月期间采集了蜜蜂和花粉样本，2017 年 7 月至 9 月期间在布尔萨（土耳其）的城市和半城市地区采集了蜂蜜样本。通过气相色谱-微电子捕获检测器（GC-μECD）测量的 PCB 浓度分别为 135.46 ± 6.53、81.47 ± 23.52 和 106.35 ± 21.60 ng g 干重（dw）的蜜蜂、花粉和蜂蜜样本；在城市地区分别为 126.35 ± 26.54、67.57 ± 27.34 和 118.88 ± 55.28 ng g dw 的蜜蜂、花粉和蜂蜜样本；在半城市地区分别为 126.35 ± 26.54、67.57 ± 27.34 和 118.88 ± 55.28 ng g dw 的蜜蜂、花粉和蜂蜜样本。对气象参数和污染物浓度进行了皮尔逊相关性分析。根据相关结果，发现半城市地区的花粉和蜂蜜结果与总云量和温度之间存在显著关系。应用发散系数（COD）和皮尔逊相关系数（PCC）方法来确定两个地区的污染物浓度和来源及其时间变化的相似性和差异。根据这两种方法，城市和半城市地区蜜蜂和花粉样本中的 PCB 浓度和排放源在 5 月和 6 月通常不同，而在 8 月和 9 月则相似。
