Information on temporal distribution of polychlorinated biphenyls (PCBs) in the coastal sediments of Mediterranean Sea, Mersin was compiled using data published between 1980 and 2009, and the present study. The first congener specific PCB results from the region yield concentration levels of Σ(41)PCBs in sediments ranging from 0.61 to 1.04 ng g(-1). Sediment profiles show penta-, hexa- and hepta-chlorobiphenyls, specifically, #149 and 153 as the most abundant congeners in all samples. Comparison of total PCB concentrations over time suggests no recent PCB input to the region. Using congener specific PCB data for the region, identity and contribution of PCB sources were also predicted using a chemical mass balance -based (CMB) receptor model. The CMB model identified Aroclor 1260 to be the major PCB source in coastal sediments. The potential sources for the PCBs were briefly discussed in terms of their use in various industrial applications.
使用 1980 年至 2009 年期间发表的数据和本研究，编译了地中海梅尔辛沿海沉积物中多氯联苯（PCBs）的时间分布信息。该地区的第一个特定同系物 PCB 结果得出，沉积物中Σ（41）PCBs 的浓度范围为 0.61 至 1.04ng/g。沉积物剖面显示，在所有样本中，五氯、六氯和七氯联苯，特别是#149 和 153 是最丰富的同系物。随着时间的推移，对总 PCB 浓度的比较表明，该地区最近没有 PCB 输入。使用该地区的特定同系物 PCB 数据，还使用基于化学质量平衡的（CMB）受体模型预测了 PCB 源的身份和贡献。CMB 模型确定 Aroclor 1260 是沿海沉积物中主要的 PCB 源。简要讨论了这些 PCB 的潜在来源，因为它们在各种工业应用中的使用。
