摘要
对济宁市12个县市区随机抽样,调查乙烯利在蔬菜生产中的使用对象、使用方法、使用时期、使用浓度、使用目的及效果。采集蔬菜样品6次、6种、共68份,利用气相色谱法测定乙烯利的残留量。结果表明:乙烯利检出(含量≥0.01 mg/kg)59份,检出率86.76%,残留量较大的样品(≥2.00mg/kg)有3份,均是番茄。参照我国及其它多数国家和组织的残留限量标准(2 mg/kg),29份番茄样品合格率89.66%,其它5种蔬菜、39份样品参照美国的黄瓜残留限量标准(0.1mg/kg),合格率92.31%。
The randomized sample of 12 counties in Jining was made to investigate the the use object, the method, the use time, the use concentration, the purpose, and the effect of ethephon in the production of vegetables. Vegetable samples were collected 6 times, 6 kinds, 68 copies, using gas chromatography to detenrfine the residues of ethephon. The results showed that the detection amount of ethephon （content≥0. 01 mg/kg） was 59 copies, and the detection rate was 86.76% ,with 3 higher residual samples （≥2. 00 mg/kg） being all tomatoes. Refered to the residue limits （2 nag/ kg） in China and the majority of other countries and organizations, the pass rate in 29 copies of tomato samples was 89. 66%. Refered to the American cucumber residue limits （0. 1 mg/kg） ,the other five kinds of vegetables of 39 samples had a pass rate of 92. 31%.
