The concentrations of 16 polycyclic aromatic hydrocarbons (PAHs) were determined in sediments from the southern Caspian Sea in fall 2015 and winter 2016. The sum of 16 PAH (ΣPAH) concentrations varied from 17.3±3.05 to 926.7±157.37ngg dry weight and 14.3±0.58 to 85.8±4.41ngg dry weight in fall and winter, respectively. There was no significant correlation between PAH and total organic carbon contents (p>0.05). PAH source identification showed that the PAHs in the sediments originated from petroleum and petroleum combustion. When classified according to the pollution levels, sediments from the southern Caspian Sea could be considered to be low to moderately polluted with PAHs.
2015 年秋季和 2016 年冬季，测定了里海南部海域沉积物中 16 种多环芳烃（PAHs）的浓度。ΣPAH 浓度分别在秋季和冬季的变化范围为 17.3±3.05 至 926.7±157.37ngg 干重和 14.3±0.58 至 85.8±4.41ngg 干重之间。PAH 与总有机碳含量之间无显著相关性（p＞0.05）。多环芳烃来源分析表明，沉积物中的多环芳烃来源于石油和石油燃烧。按照污染水平分类，里海南部海域的沉积物可被认为是低到中度多环芳烃污染。
