中文摘要：本研究以2014-2015年智利中北部农区118种叶菜类蔬菜为样本，采用QuEChERS方法与气相色谱-高效液相色谱法研究该地区农药残留浓度及潜在人体健康风险。结果发现，27%的样本中农药残留量超过了各活性成分的最大残留限值，硫化碳、甲胺磷、嘧菌酯和氯氰菊酯的每日最大摄入量分别为0.57、0.07、0.06和0.05mg/kg，均高于其每日可接受摄入量。因此，除了甲胺磷外，叶菜类蔬菜对智利中北部农区居民并没有造成健康风险，但是高浓度的甲胺磷是一种潜在的慢性健康威胁。
外文摘要：To investigate pesticide residue concentrations and potential human health risk, a study was conducted in 118 leafy vegetable samples collected in 2014-2015 from the North Central agricultural areas of Chile. The pesticide residues were determined using the multiresidue QuEChERS method by gas chromatography as well as high-performance liquid chromatography. The results indicated that 27% of the total samples contained pesticide residues above the maximum residue limits of each active ingredient. The maximum estimated daily intake obtained for carbon disulphide (CS2), methamidophos, azoxystrobin and cypermethrin were 0.57, 0.07, 0.06 and 0.05mgkg(-1), respectively, which was higher than their acceptable daily intake. It is concluded that inhabitants of the North Central agricultural area of Chile are not exposed to health risks through the consumption of leafy vegetables with the exception of methamidophos. Nevertheless, the high levels of methamidophos detected in leafy vegetables could be considered a potential chronic health risk.
