摘要
采用固相萃取和气相色谱/质谱法同时测定了同一生产线不同生产点抽取的同一牌号31个烟丝样品中的氯菊酯、氟氯氰菊酯、氯氰菊酯、顺式氯氰菊酯和溴氰菊酯残留量。结果表明:①5种拟除虫菊酯的检出限在2.9-36μg/kg之间,平均回收率为75.7%-110.0%,相对标准偏差0.65%-5.63%;②样品中均残留氯菊酯、氟氯氰菊酯、氯氰菊酯和顺式氯氰菊酯,但均未超过最高残留限量。
The residues of permethrin, cylfuthrin, cypermethrin, alphacypermethrin, and dehamethrin in 31 cut tobacco samples of the same brand from different sites in a primary processing line were determined simul- taneously by SPE and GC/MS. The results showed that the recoveries of the five pyrethroids ranged from 75.7% to 110% with 0.65% to 5.63% (n = 6) of RSD and 2.9-36 μg/kg of the limits of detection. The permethrin, cylfuthrin, cypermethrin and alphacypermethrin were detectable in all the samples, however their contents were all below maximum residue limit.
