The concentrations and distributions of polycyclic aromatic hydrocarbons (PAHs) were examined from 2008 to 2014 in the surface waters of the Japan Sea region. PAH concentrations decreased in the Japan Sea and Tsushima Strait; consistent with improvements in atmospheric pollution from Japan. There were no changes in the Korean Strait, suggesting a continual influx of contamination separate from the Japan Sea. At all sites, PAHs in the dissolved phase were greater than in the particulate phase. A separate survey in 2011 studied whether contamination in the Kuroshio current accounted for the contamination in the Tsushima strait and Japan Sea. PAH concentrations increased as waters moved into the Tsushima strait and the Japan Sea, suggesting inputs were local and not from the Kuroshio current. This was however confounded by the greater influence of particulate phase PAHs, which are likely deposited by seasonal desert storms.
从 2008 年至 2014 年，对日本海地区地表水的多环芳烃（PAHs）浓度和分布进行了研究。随着日本大气污染的改善，日本海和对马海峡的 PAH 浓度有所下降。而在朝鲜海峡，情况则没有变化，这表明存在与日本海无关的持续污染流入。在所有采样点，溶解态的多环芳烃都大于颗粒态。2011 年的一项单独调查研究了黑潮是否导致了对马海峡和日本海的污染。当水体进入对马海峡和日本海时，PAH 浓度增加，表明污染物是本地输入的，而不是来自黑潮。然而，这与颗粒相 PAHs 的更大影响相混淆，颗粒相 PAHs 可能是由季节性沙漠风暴沉积的。
