Research in Utilization of Current Situation,Residue Measurement and Safety Evaluation of Ethephon in Vegetables

XU Ai-dong (Department of Life Science and Engineering,Jining University,Qufu,Shandong 273100)  
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 determine 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(≥2.00mg/kg) being all tomatoes.Refered to the residue limits(2 mg/ 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%.
