We studied 19 targets currently using organochlorine pesticides (CUOCPs) from 98 samples in the Western Pacific Ocean and the East China Sea collected in 2019, 2020, and 2021. The samples were analyzed using a novel High-throat/High-volume Solid-Phase Extraction method. Eighteen individual CUOCPs were above the method detection limits. The levels of ∑CUOCPs ranged from 0.13 to 17.80 ng/L, with an average of 3.13 ± 14.67 ng/L. Dicofol was the main pollutant in the Western Pacific Ocean, while Pyridaben dominated the East China Sea. In the summer, land-source input was the primary source in the Western Pacific Ocean and the East China Sea. Historical residues were the main source in the East China Sea in spring. In the summer, the ecological risk assessment results indicated a relatively low risk to the Western Pacific Ocean and the East China Sea.
我们研究了来自 2019 年、2020 年和 2021 年在西太平洋和东海采集的 98 个样本中目前使用的 19 种有机氯农药（OCPCs）。这些样本使用一种新的高通量固相萃取方法进行了分析。18 种单一的 OCPC 超过了方法检测限。∑OCPCs 的水平范围从 0.13 到 17.80 ng/L，平均值为 3.13 ± 14.67 ng/L。在西太平洋，三氯杀螨醇是主要污染物，而在东中国海，主要污染物是哒螨灵。在夏季，陆源输入是西太平洋和东中国海的主要来源。在春季，历史残留是东中国海的主要来源。在夏季，生态风险评估结果表明，西太平洋和东中国海的风险相对较低。
