Abstract： This study detected the residues of organophosphorus and carbamate pesticides in 1 569 vegetable samples colected inTianshuicityin2O24andanalyzedtheseasonalitydiferences invegetablevarieties，and their correlation with temperature.Theresearch adopted the enzyme inhibition method forrapid detection，and the results showed that the overall pesticide residue levels were comparatively low， with an annual pass rate of 97.99% . Among different months， the pass rate was relatively lower from January to March （95.58%～96.20%） ，while the highest pass rate was observed in August （99.13%） ）.The monthly pass rate was extremely significantly positively correlated with both the average high temperature and the average low temperature （ （P<0.01 ）. Among vegetable varieties， root and tuber vegetables had the highest pass rate （98.88%） ， while leafy vegetables had the lowest pass rate （97.04% ）

Keywords： pesticide residues; vegetable safety; enzyme inhibition method; temperature correlation
