多氯联苯（PCBs），多环芳烃（PAHs），并在塑料树脂颗粒收集的分析沿着波斯湾海岸线的19个地点。多氯联苯在靠近工业区的地方含量很高，其浓度（13种同系物之和，54-624纳克/克颗粒）高于沿海农村城镇，后者接近全球背景水平（<10纳克/克颗粒）。多环芳烃浓度（27种多环芳烃的总和）从273到15，786纳克/克颗粒不等，在工业城市（布什尔和班达尔阿巴斯）最高，在大多数地点都有成岩特征，可能是由于石油工业、炼油厂和油轮。在全球范围内，这些水平被归入极度污染类别。藿烷类的分布相对均匀，其浓度范围为8048- 59778纳克/克颗粒。该范围与PAH浓度呈正相关。PAH和藿烷的结果强调了波斯湾石油污染的普遍性。
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.
