河北省市售水果中植物生长调节剂残留状况 调查与分析
目的 了解河北省市售水果(草莓、葡萄、猕猴桃、樱桃和西瓜)中植物生长调节剂赤霉素、氯吡脲、噻苯隆、2, 4-二氯苯氧乙酸、4-氯苯氧乙酸和多效唑残留状况。方法 对河北地区148份草莓、122份葡萄、51份猕猴桃、39份樱桃和9份西瓜中植物生长调节剂残留状况进行研究。参考食品中化学污染物及有害因素监测技术手册方法, 采用液相色谱-串联质谱法进行检测。结果 148份草莓样品中多效唑检出39份; 51份猕猴桃样品中氯吡脲检出23份; 39份樱桃样品中2,4-二氯苯氧乙酸检出16份; 其他植物生长调节剂在各类水果中检出率均不高。结论 植物生长调节剂在河北省市售的各类水果中存在不同程度的残留, 但残留量较低, 总体安全性较好。
Objective To investigate the residue status of gibberellin, clopidamide, thiabenon, 2,4-dichlorophenoxyacetic acid, 4-chlorophenoxyacetic acid and polyazole in fruits (strawberries, grapes, kiwi, cherries and watermelon) sold in Hebei province. Methods Plant growth regulator residues in 148 strawberries, 122 grapes, 51 kiwifruits, 39 cherries and 9 watermelons in Hebei were studied. Reference to the technical manual method for monitoring chemical pollutants and harmful factors in food, liquid chromatography-tandem mass spectrometry was used for detection. Results Totally 39 of 148 strawberry samples were detected by polyprazole, 23 of 51 kiwifruit samples were detected with clopidoide, and 16 of 39 cherry samples were detected with 2,4-dichlorophenoxyacetic acid. The detection rate of other plant growth regulators in various fruits was not high. Conclusion The data showed that different degrees of residues of plant growth regulators were existed in all kinds of fruits in Hebei province, but the residues were lower and safety for people.
