In this study, we reported the occurrence of eight organophosphorus pesticides (OPPs) in the East China Sea. Forty samples were collected and analysed with a high volume solid phase extraction method (Hi-throat/Hi-volume SPE) in the early summer of 2020. All the target OPPs were detected in the surface water at one or more stations in the East China Sea, and the concentrations of ΣOPPs were in the range 0.0775-3.09 ng/L (mean: 0.862 ± 0.624 ng/L). Terbufos sulfone and fenthion were the main pollutants in this area, probably resulting from pesticide use in China and other countries. The off-shore input from coastal regions was suggested to be a major source of OPP pollution in the East China Sea, and the movement of ocean currents played an important role in their transportation because around 0.86 t OPPs passed through the Tsushima Strait from the East China Sea each month. An ecological risk assessment showed that these OPPs presented a high risk to species in the East China Sea, whereas they posed no health risk to humans under both the median and high exposure scenario.
本研究报道了东海 8 种有机磷农药（OPPs）的存在。2020 年初夏，采用大容量固相萃取法（Hi-throat/Hi-volume SPE）采集了 40 个样本并进行了分析。东海的一个或多个站位的表层水中均检测到所有目标 OPPs，ΣOPPs 的浓度范围为 0.0775-3.09ng/L（平均值：0.862±0.624ng/L）。特丁硫磷砜和倍硫磷是该地区的主要污染物，可能是由于中国和其他国家使用农药所致。沿海地区的离岸输入被认为是东海 OPP 污染的主要来源，洋流的运动在它们的运输中起着重要作用，因为每月约有 0.86 吨 OPPs 通过对马海峡从东海进入日本海。生态风险评估表明，这些 OPPs 对东海的物种构成高风险，而在中值和高暴露情景下，它们对人类没有健康风险。
