In this study, pesticide residues in parsley, lettuce and spinach (120 samples) were analyzed by the application of liquid chromatography-tandem mass spectrometry (LC-MS/MS). All samples of spinach, parsley or lettuce contained residues of three or more active substances. In parsley, carbendazim (100.0%), dichlorvos (100.0%), fenarimol (40.0%), pendimethalin (95.0%), in lettuce, diazinon (30.0%), dichlorvos (100.0%), pendimethalin (92.5%) phenthoate (12.5%), and in spinach, carbendazim (45.0%), cymoxanil (85.0%), dichlorvos (100.0%) and fenarimol (85.0%) were the significant active compounds. The maximum residue limits were exceeded in 28, 20 and 40 samples of parsley, lettuce and spinach, respectively. The results showed that there was a high occurrence of pesticide residues in parsley, lettuce and spinach samples from Hatay province, in which most of them were prohibited from use in Turkey for these vegetables. The contamination levels of these residues may be considered a serious public health problem according to the maximum residue limits (MRLs) of Turkey and the European Union (EU).
本研究采用液相色谱-串联质谱法（LC-MS/MS）分析了欧芹、生菜和菠菜（120 个样本）中的农药残留。所有菠菜、欧芹或生菜样本均含有三种或更多种活性物质的残留。在欧芹中，多菌灵（100.0%）、敌敌畏（100.0%）、苯醚甲环唑（40.0%）、二甲戊灵（95.0%），在生菜中，二嗪磷（30.0%）、敌敌畏（100.0%）、二甲戊灵（92.5%）、乐果（12.5%），在菠菜中，多菌灵（45.0%）、霜脲氰（85.0%）、敌敌畏（100.0%）和苯醚甲环唑（85.0%）是主要的活性化合物。多菌灵、敌敌畏、二甲戊灵和乐果在 28、20 和 40 个欧芹、生菜和菠菜样本中的残留量超过了最大残留限量。结果表明，哈塔伊省的欧芹、生菜和菠菜样本中农药残留的发生率很高，其中大多数在土耳其已被禁止用于这些蔬菜。根据土耳其和欧盟（EU）的最大残留限量（MRLs），这些残留的污染水平可能被认为是一个严重的公共卫生问题。
