A method coupling thermal desorption and gas chromatography/mass spectrometry (GC/MS) was developed for the simultaneous determination of 7 pyrethroids (allethrin, bifenthrin, cyphenothrin, imiprothrin, permethrin, prallethrin and tetramethrin) and piperonyl butoxide adsorbed on Tenax TA(®) passive samplers after exposure in indoor air. Thermal desorption was selected as it permits efficient and rapid extraction without solvent used together with a good sensitivity. Detection (S/N>3) and quantification (S/N>10) limits varied between 0.001 ng and 2.5 ng and between 0.005 and 10 ng respectively with a reproducibility varied between 14% (bifenthrin) and 39% (permethrin). The method was used for the comparison indoor air contamination after low-pressure spraying and fumigation application in a rubbish chute situated in the basement of a building.
开发了一种热解吸和气相色谱/质谱联用(GC/MS)的方法,用于同时测定室内空气中 Tenax TA(®)被动采样器吸附的 7 种拟除虫菊酯(丙烯菊酯、联苯菊酯、氯菊酯、氯菊酯、氯菊酯、炔丙菊酯和四氟菊酯)和增效醚。选择热解吸是因为它可以在不使用溶剂的情况下进行高效快速的提取,并且具有良好的灵敏度。检测(S/N>3)和定量(S/N>10)限分别在 0.001ng 和 2.5ng 之间以及 0.005ng 和 10ng 之间,重现性在 14%(联苯菊酯)至 39%(氯菊酯)之间变化。该方法用于比较在建筑物地下室垃圾滑槽中进行低压喷雾和熏蒸处理后室内空气的污染情况。
