This study validated the analysis of organochlorine pesticides (OCPs) in shellfish and cephalopods using a gas chromatograph equipped with a mass spectrometry (GC–MS/MS), and monitored residual pesticide levels. The QuEChERS method was used to analyze OCPs and was validated by checking the linearity, limit of detection (LOD), limit of quantitation (LOQ), accuracy, and precision. Octopus minor and Venerupis philippinarum, were purchased from four cities in the South Korean peninsula. The LOD values were 0.10–0.80 ng/g in shellfish and 0.21–0.77 ng/g in cephalopods, while the LOQ values were 0.31–2.41 ng/g in shellfish and 0.63–2.33 ng/g in cephalopods. Accuracy ranged from 83.5 to 117.4% and 79.8 to 118.4%, and precision ranged from 0.3 to 27.5% and 1.2 to 27.9%, in shellfish and cephalopods, respectively, conforming to the Codex Alimentarius Commission guidelines. Although residual OCP levels were below detection limits, the QuEChERS method may be effective for analyzing the OCPs in shellfish and cephalopods.

这项研究使用配备质谱仪（GC-MS / MS）的气相色谱仪验证了贝类和头足类动物中有机氯农药（OCP）的分析，并监测了残留农药的水平。QuEChERS方法用于分析OCP，并通过检查线性，检测限（LOD），定量限（LOQ），准确性和精密度进行了验证。小章鱼和菲律宾金龟子，是从韩国半岛的四个城市购买的。贝类的LOD值为0.10–0.80 ng / g，头足类的LOD值为0.21–0.77 ng / g，贝类的LOQ值为0.31–2.41 ng / g，头足类的LOQ值为0.63–2.33 ng / g。符合食品法典委员会的规定，贝类和头足类动物的准确度分别为83.5至117.4％和79.8至118.4％，精确度为0.3至27.5％和1.2至27.9％。尽管残留的OCP水平低于检测极限，但QuEChERS方法对于分析贝类和头足类动物的OCP可能是有效的。
