Evaluation of the quality of indoor air was carried out in 20 apartments, 3 offices, and 3 laboratories in the Tricity area in Poland with reference to concentrations of selected volatile organic compounds (VOCs), such as benzene, toluene, butyl acetate, ethylbenzene, m-xylene, styrene, and m-dichlorobenzene. The time dependence of concentrations of selected VOCs in a newly erected building was studied. Two different techniques were used for the isolation and preconcentration of analytes from air samples: a passive method employing a home-made permeation-type passive sampler and a dynamic method based on a sorption tube. In both cases, activated charcoal was used as a sorption medium (trap packing). The sorption tube was used to validate the results obtained by the passive method, as well. In the majority of dwellings examined, the concentrations of air pollutants were relatively low and did not exceed the MAC values. No significant differences were observed between MAC concentrations determined by using the passive or the dynamic method of air sampling. The results obtained by both sampling methods were characterized by similar precision.
在波兰特罗茨基地区的20套公寓、3间办公室和3间实验室中，针对选定的挥发性有机化合物（VOCs），如苯、甲苯、乙酸丁酯、乙苯、间二甲苯、苯乙烯和间二氯苯的浓度，对室内空气质量进行了评估。研究了新建建筑中选定VOCs浓度的时间依赖性。采用两种不同技术从空气样品中分离和预浓缩分析物：一种是使用自制渗透型被动采样器的被动方法，另一种是基于吸附管的动态方法。在这两种情况下，均使用活性炭作为吸附介质（捕集阱填料）。吸附管也用于验证被动方法获得的结果。在所检查的大多数住宅中，空气污染物浓度相对较低，未超过MAC值。使用被动或动态空气采样方法测定的MAC浓度之间未观察到显著差异。两种采样方法获得的结果具有相似的精密度。
