Polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), and hopanes were analyzed in plastic resin pellets collected from 19 locations along the Persian Gulf coastline. PCBs were high at locations near industrial areas, where their concentrations (sum of 13 congeners, 54-624 ng/g-pellet) were higher than those in rural coastal towns, which were close to global background levels (<10 ng/g-pellet). PAH concentrations (sum of 27 PAH species) varied from 273 to 15,786 ng/g-pellet and were highest in industrial cities (Bushehr and Bandar Abbas), with a petrogenic signature at most locations, possibly due to the petroleum-based industries, refineries, and tankers. These levels were placed in the extremely polluted category on a global basis. The distribution of hopanes was relatively homogeneous, and their range of concentrations was 8048-59,778 ng/g-pellet. This range had a positive correlation with PAH concentrations. The PAH and hopane results emphasize the ubiquity of petroleum pollution in the Persian Gulf.
多氯联苯（PCBs）、多环芳烃（PAHs）和藿烷在沿波斯湾海岸线的 19 个地点采集的塑料树脂颗粒中进行了分析。在靠近工业区的地点，PCBs 含量较高，其浓度（13 种同系物的总和，54-624ng/g-颗粒）高于靠近全球背景水平（<10ng/g-颗粒）的农村沿海城镇。PAH 浓度（27 种 PAH 种类的总和）从 273 到 15786ng/g-颗粒不等，在工业城市（布什尔和阿巴斯港）最高，在大多数地点具有源自石油的特征，可能是由于石油工业、炼油厂和油轮。根据全球标准，这些水平被归为极度污染类别。藿烷的分布相对均匀，其浓度范围为 8048-59778ng/g-颗粒。该范围与 PAH 浓度呈正相关。PAH 和藿烷的结果强调了石油污染在波斯湾的普遍性。
