This paper reports the results of a pesticide monitoring survey on wine grapes from the 2008-2010 vintage from vineyards grown according to integrated pest management strategies. A multi-residue gas chromatography-mass spectrometry method in electron ionization and chemical ionization mode has been used for the determination of 30 pesticides in wine samples. The analytical method showed good recoveries and allowed a good separation of the selected pesticides. Repeatability and intermediate precision showed good results with CV < 20 %. The instrumental method limits of determination (LOD) and of quantification (LOQ) were below the maximum residue levels set in wine. The analysis of the wines showed that pesticide residues were below the instrumental LOQ, and most of them were undetectable (<LOD). Only the 38 % of the pesticide applied has been detected in at least one cultivar. Metalaxil, myclobutanil, and penconazole were the pesticides most frequently found, while carignano and vermentino were the cultivars with the higher number of residues.
本论文报告了 2008-2010 年份间，采用病虫害综合治理策略种植的葡萄园里的酿酒葡萄的农药监测调查结果。采用电子电离和化学电离模式的多残留气相色谱-质谱法测定了葡萄酒样品中的 30 种农药。该分析方法的回收率良好，可对所选农药进行良好的分离。重复性和中间精密度的 CV 值<20%，结果良好。仪器方法的检测限（LOD）和定量限（LOQ）均低于葡萄酒中的最大残留限量。对葡萄酒的分析表明，农药残留均低于仪器的检测限，且大部分为不可检测（<LOD）。只有 38%的施用药剂在至少一个品种中被检测到。金属乐灵、戊菌唑和咪鲜胺是最常被检出的农药，而佳丽酿和维蒙蒂诺是残留数量较高的品种。
