为研究复配试剂噁唑菌酮和代森锰锌可分散粒剂在番茄和土壤中施用后的食品安全性和环境归宿行为,将杀菌剂施用于番茄植株农药残留消解动态试验小区(15 m2)和土壤动态试验小区(20 m2),结合HPLC和GC检测技术,通过添加回收建立噁唑菌酮、代森锰锌在番茄和土壤基质中的残留检测方法.结果表明:噁唑菌酮在番茄和土壤中的最小检出量分别为1×10-9 g和8×10-9 g,最低检出浓度均为0.05 mg/kg,代森锰锌的最小检出量为3.5×10-11g,最低检出浓度为0.035 mg/kg,平均回收率(n=5)为78.01％ ～106.03％,相对标准偏差平均值均小于5.22％.该方法重复性好,准确度高,试验结果表明番茄中噁唑菌酮、代森锰锌的半衰期为...

To study the environmental fate and behavior of the compounding agents famoxadone and mancozeb dispersible granules and their impacts on food safety after application in tomato and soil ecosystems,the fungicides were applied to the plot of pesticide residue digestion dynamic test on tomato plant(15 m^2)and the plot of soil dynamic test(20 m^2).With HPLC and GC detection techniques integrated,a method for detecting residues of famoxadone and mancozeb in tomato and soil matrix was established by adding recovery experiments.The results show that:T...
