Polyurethane foam (PUF) passive samplers were employed to assess air concentrations of polychlorinated biphenyls (PCBs) in background, agricultural, semi-urban, urban and industrial sites in Bursa, Turkey. Samplers were deployed for approximately 2-month periods from February to December 2014 in five sampling campaign. Results showed a clear rural-agricultural-semi-urban-urban-industrial PCBs concentration gradient. Considering all sampling periods, ambient air concentrations of ΣPCBs ranged from 9.6 to 1240 pg/m at all sites with an average of 24.1 ± 8.2, 43.8 ± 24.4, 140 ± 190, 42.8 ± 24.6, 160 ± 280, 84.1 ± 105, 170 ± 150 and 280 ± 540 pg/m for Mount Uludag, Uludag University Campus, Camlica, Bursa Technical University Osmangazi Campus, Hamitler, Agakoy, Kestel Organised Industrial District and Demirtas Organised Industrial District sampling sites, respectively. The ambient air PCB concentrations increased along a gradient from background to industrial areas by a factor of 1.7-11.4. 4-Cl PCBs (31.50-81.60%) was the most dominant homologue group at all sampling sites followed by 3-Cl, 7-Cl, 6-Cl and 5-Cl homologue groups. Sampling locations and potential sources grouped in principal component analysis. Results of PCA plots highlighted a large variability of the PCB mixture in air, hence possible related sources, in Bursa area. Calculated inhalation risk levels in this study indicated no serious adverse health effects. This study is one of few efforts to characterize PCB composition in ambient air seasonally and spatially for urban and industrial areas of Turkey by using passive samplers as an alternative sampling method for concurrent monitoring at multiple sites.
聚亚安酯泡沫(PUF)被动采样器被用来评估土耳其布尔萨的背景、农业、半城市、城市和工业区空气中多氯联苯(PCBs)的浓度。采样器于 2014 年 2 月至 12 月期间进行了大约 2 个月的部署,共进行了五次采样活动。结果显示出明显的农村-农业-半城市-城市-工业 PCBs 浓度梯度。考虑到所有的采样时期,所有地点的环境空气总 PCBs 浓度范围为 9.6 至 1240 pg/m3,平均值为 24.1±8.2、43.8±24.4、140±190、42.8±24.6、160±280、84.1±105、170±150 和 280±540 pg/m3,分别为乌鲁达山、乌鲁达大学园区、卡姆利卡、布尔萨技术大学奥斯曼加济校区、哈米特勒、阿加科伊、凯斯特勒组织工业区和德米塔斯组织工业区采样点。环境空气中的 PCB 浓度沿着从背景到工业区的梯度增加了 1.7-11.4 倍。所有采样点中最主要的同系物组是 4-Cl PCBs(31.50-81.60%),其次是 3-Cl、7-Cl、6-Cl 和 5-Cl 同系物组。主成分分析将采样地点和潜在源进行了分组。主成分分析图的结果突出显示了在布尔萨地区,空气中 PCB 混合物存在很大的变异性,因此可能存在相关来源。本研究中计算的吸入风险水平表明没有严重的不良健康影响。本研究是为数不多的使用被动采样器作为多个地点同时监测的替代采样方法,对土耳其城市和工业区环境空气中 PCBs 组成进行季节性和空间性特征描述的努力之一。
