Abstract The aim of this study was the identification of the factors that determine the concentrations of particulate matter (PM) in the indoor air of a selected sports facility, as well as the assessment of the health exposure of the sports facility users (pupils aged 8–18 years, trainers and athletes aged 21–40 years) to PM and its components. The mass concentration of size-resolved (PM1, PM1-2.5, PM2.5-4, PM4-10, PM10-100) total suspended particles (TSP) was measured using DustTrak DRX devices. Measurements were conducted for 8 h a day, simultaneously inside and outside a typical sports hall in Warsaw, for 20 days each in the heating (16/10/–20/11/2017) and non-heating (18/05/–21/06/2017) seasons. At the same time, samples of PM4 and TSP were taken (GilAir 3 aspirators) to determine ambient concentrations of PM-bound metals and polycyclic aromatic hydrocarbons (PAH). The main factor affecting TSP concentration in the sports facility was dust resuspension; it was especially visible in variations of coarse PM concentrations. The concentrations of fine PM as well as PM-bound metals and PAHs inside the hall were determined mainly by outdoor sources – combustion of fossil fuels and non-traffic emissions. The incremental lifetime cancer risk (ILCR) related to the exposure of the sports hall users to PM-bound metals and PAHs was in the range of 6.9E-05–1.1E-04; it was higher than that calculated for PM-bound metals and PAHs in atmospheric air (5.4E-05–9.8E-05). The highest ILCR concerns pupils, which inside the sports facility is above the acceptable risk level value of 1E-04.

与颗粒物理化特性​​相关的室内运动中心使用者的健康暴露

摘要 本研究的目的是确定决定选定体育设施室内空气中颗粒物 (PM) 浓度的因素，以及评估体育设施使用者（8 岁以下的学生）的健康暴露情况。 –18 岁（21-40 岁的教练员和运动员）到 PM 及其组成部分。使用 DustTrak DRX 设备测量尺寸分辨（PM1、PM1-2.5、PM2.5-4、PM4-10、PM10-100）总悬浮颗粒 (TSP) 的质量浓度。测量时间为 8 公顷，在华沙一个典型的体育馆内外同时进行，在加热 (16/10/–20/11/2017) 和非加热 (18/05/–21/) 中各 20 天06/2017) 季节。同时，采集 PM4 和 TSP 样本（GilAir 3 吸气器）以确定 PM 结合金属和多环芳烃 (PAH) 的环境浓度。影响体育设施TSP浓度的主要因素是粉尘再悬浮；这在粗颗粒物浓度的变化中尤为明显。大厅内细颗粒物以及与颗粒物结合的金属和多环芳烃的浓度主要取决于室外来源——化石燃料的燃烧和非交通排放。与运动场用户暴露于 PM 金属和 PAH 相关的终生癌症风险增加 (ILCR) 范围为 6.9E-05–1.1E-04；它高于大气中 PM 结合金属和 PAH 的计算值 (5.4E-05–9.8E-05)。ILCR 最高的是学生，
