中文摘要:本文采用改进的QuEChERS方法和超高效液相色谱-质谱联用技术对96个新鲜水果样品进行植物生长调节剂调查和农药残留测定,测定结果参照国家监管部门规定的最大残留限(MRLs)进行衡量。结果表明:蓝莓、荔枝、西瓜均未检测到农药残留,只有一种水果(占比1%)的农药残留量高于MRLs。对常规农药残留进行检测,结果在20%的水果样本中检测到多菌灵残留。根据试验数据评估农药残留的健康风险,结果发现:短期健康风险概率低于3.25%;长期健康风险概率非常低,其中烯酰吗啉为0.0005%,咪鲜胺为0.4302%。
外文摘要:A total of 96 samples of fresh fruits were collected to investigate the residues of selected plant growth regulators and fungicides. The analyses utilized ultra-high-performance liquid chromatography coupled with tandem mass spectrometry after a modified QuEChERS method. The results were evaluated according to maximum residue limits ( MRLs) by the Chinese regulation. All blueberries, litchis, and watermelons were pesticide-free, and only one ( 1%) fruit sample contained pesticide residues above MRLs. Concerning the most frequently detected pesticide residues, carbendazim was found in 20% of the samples analyzed. Data obtained were then used to estimate the potential health risks associated with the exposures to these pesticides. The short-term risks were below 3.25% and the long-term risks were also very low, ranging from 0.0005% for dimethomorph to 0.4302% for prochloraz.
