Abstract

The development of an air sampler and its use in measuring organic pollutants in operating theatre atmospheres are described. Air was sampled continuously during an operating session and the results obtained represent the average pollution at the sample site during that session. The technique involved the chemical adsorption of organic vapours to polymer beads and pollutants thus trapped could be stored for several days before thermal desorption and analysis by gas chromatography. The three most abundant organic pollutants were ethanol, propan-2-ol (isopropanol) and halothane.

摘要

本文描述了一种空气采样器的研制及其在测量手术室空气中有机污染物方面的应用。在一次手术过程中持续采集空气样本，所获得的结果代表了该时段采样点的平均污染情况。该技术涉及将有机蒸汽化学吸附到聚合物珠上，捕获的污染物在热脱附和气相色谱分析之前可储存数天。三种含量最高的有机污染物是乙醇、丙 - 2 - 醇（异丙醇）和氟烷。
