摘　　要：目的了解大兴区主产水果中6种植物生长调节剂的使用现状,为制定食品安全政策法规提供科学依据。方法2016年从大兴区不同地点采集236份水果样品,采用液相色谱-质谱法检测6种植物生长调节剂(赤霉素、多效唑、2,4-二氯苯氧乙酸、噻苯隆、氯吡脲、4-氯苯氧乙酸)。结果在236份水果样品中植物生长调节剂总检出率为24.2%,其中桑椹中检出率为9.5%,西瓜中检出率为17.3%,葡萄中检出率为45.1%,梨中检出率为8.6%。各种植物生长调节剂的残留量普遍较低,在0.000 27 mg/kg^0.018 mg/kg。结论大兴区主产水果中植物生长调节剂残留量存在不同程度的检出,需加强监管,采取相应措施以提高食品安全性。Objective To understand the status of six plant growth regulators residues in fruits from Daxing district,so as to provide scientific evidence for developing food safety policies and regulations. Methods Two hundred and thirty-six fruit samples were collected from different places of Daxing district in 2016 and six plant growth regulators including paclobutrazol,gibberellins,2,4-dichlorophenoxyacetic acid,thidiazuron,forchlorfenuron and 4-chlorophenoxyacetic acid were detected by UPLC-MS/MS. Results The total detection rate was 24. 2% in the 236 samples. The detection rate 9. 5% in mulberry,17. 3% in watermelon,45. 1% in grape and 8. 6% in pear. But the residues of plant growth regulators were generally low,ranging from 0. 000 27 mg/kg to 0. 018 mg/kg. Conclusion The detection rates of plant growth regulators in fruits from Daxing district were different. The supervision should be strengthened and the measures should be taken to assure the safety of the food.
