摘要：

An indoor air sampling impactor (IASI) was used to sample inhalable suspended particulate matter (PM-10) in indoor air. The unit, which is convenient to use, light weight and portable, was compared in a controlled indoor setting with a Sierra-Andersen dichotomous sampler (DICHOT) equipped with a PM-10 inlet. The two samplers were used for coreplicate sampling in the same test room both in the presence of and in the absence of environmental tobacco smoke (ETS). Gravimetric analyses and mutagenicity testing of solvent extracts of the particulate matter, using the microsuspension modification of the Salmonella typhimurium mutagenicity test, were used to compare the two samplers. In a limited field trial of the IASI sampler in various residential indoor environments containing low and high ETS levels, PM-10 concentrations ranged from 20 to 3000-mu-g/m3. Mutagenic responses in the presence of the S9 metabolizing system ranged from 13 to 1300 revertants/m3.
