Traditional <i>in vivo</i> methods for determining OP toxicity are time-consuming and labor-intensive. In this study, we developed a quantitative structure-activity relationship (QSAR) model to predict acute rat toxicity of OPs using two-dimensional molecular and quantum chemical descriptors, optimized through genetic algorithm-based multiple linear regression (GA-MLR). The optimal model demonstrated robust performance with the following statistical parameters: coefficient of determination (<i>R</i>²) of 0.7451, leave-one-out cross-validation (LOOCV) coefficient (<i>Q</i>²_Loo) of 0.6208, external test set coefficient of determination (<i>R</i>²_ext) of 0.7360. These metrics indicate excellent generalization and predictive capabilities of the model. Interpretative analysis of the model revealed that NumHDonors and PEOE_VSA were the most significant descriptors influencing OP toxicity. An increase in hydrogen bond donors within OP molecules reduces toxicity, as these donors enhance hydrophilicity, diminishing membrane permeability. Moreover, the PEOE_VSA descriptor characterizes the partial charge properties of OP molecules, reflecting their electrostatic interactions with acetylcholinesterase (AChE) during binding, which influences toxicity. This study presents an optimized modeling strategy designed for small datasets, enabling stable feature selection and accurate assessment of their contributions to toxicity prediction. This research provides a reliable QSAR approach for OP toxicity prediction while offering new insights into toxicity mechanisms.</p>","PeriodicalId":15720,"journal":{"name":"Journal of Environmental Science and Health Part B-pesticides Food Contaminants and Agricultural Wastes","volume":"60 5","pages":"219-231"},"PeriodicalIF":1.4,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144011843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Validation studies were conducted with spiked pesticide standards, and commercial poultry feed samples were analyzed. The linearity of the QuEChERS method was evaluated, showing high coefficients of determination (<i>R</i>² ≥0.995) for all analytes. The method demonstrated excellent linearity (<i>R</i>² ≥0.995), recovery rates (86.8-109.2%), and precision (RSD ≤14.8%), meeting SANTE criteria. Limits of detection (LOD) ranged from 0.5 to 5 ng/kg and limits of quantification (LOQ) from 1 to 10 ng/kg, enhancing the method's reliability. Analysis of the poultry feed revealed that 15 out of the 345 pesticide residues were detected in the samples, with concentrations ranging from 2.1 to 120 µg/kg.
