摘要
[目的]系统地研究对比3种拟除虫菊酯类杀虫剂在烟丝、卷烟、卷烟主流烟气中的转移情况。[方法]研究了不同浓度的3种拟除虫菊酯类杀虫剂（氯菊酯、氟氯氰菊酯和顺式氯氰菊酯）从烟丝到卷烟再到卷烟主流烟气的转移率情况,并建立转移模型。[结果]试验表明,不同浓度的3种杀虫剂从烟丝到卷烟的过程中转移率较高,在99%以上;而从烟丝或卷烟转移到卷烟主流烟气的比例很低,在0～9.78%,平均转移率最高的是氟氯氰菊酯,其次是顺式氯氰菊酯,转移率最小的是氯菊酯。经过8个验证样品对所建立的转移模型的验证试验表明,通过转移模型所计算出来的含量结果与通过试验方法得到的检测结果之间的相对偏差均在10%以下,表明所建立的转移模型具有良好的准确性和可靠性。[结论]研究可为烟叶生产中杀虫剂的选择提供参考依据。
[Objective] The transfer situation of three pyrethroids in cut tobacco,tobacco and mainstream smoke was studied. [Method]Three pyrethroids（ permethrin,cyfluthrin and cypermethrin） residues transferred from tobacco to cigarette and cigarette to mainstream smoke were studied,the trnsfer model was established. [Result] The result showed that transfer rate from tobacco to cigarette of each pesticide with different concentrations was particularly high,more than 99%,while from cigarette to mainstream smoke,it was low,bewteen 0- 9. 78%,the highest of average transfer rate is cyfluthrin,followed by cypermethrin,the smallest is permethrin. Method validation experiment of eight samples for establishing transfer model showed,compared with contents calculated by previously established transfer model,the relative deviation of the result was below 10%,which proves the transfer model extablished in this paper has good accuracy and reliability. [Conclusion]The study can provide reference basis for selection of insecticide in tobacco production.
