In this study, volatile organic compounds (VOCs) were measured from 47 hospital rooms to determine the most suitable sampling location for VOCs indoors. Another goal was to find out the most predominant VOCs and their emission per floor area in a hospital environment. Three samples were taken from each room simultaneously: one from the center of the room, one from the floor near the wall, and one from the exhaust air terminal. Concentrations of the VOCs were relatively low in all the cases, and the most abundant compounds were decamethylcyclopentasiloxane, d-limonene, xylenes, and 2-methyl-2-propanol. The average emission rates of the main compounds per floor area varied between 49 and 81 µg/m²h. Statistical analyses showed that room area and volume affected differently the total volatile organic compounds (TVOC) concentrations among the sampling locations. Concentrations were higher at the exhaust air terminal than in samples at the floor and middle of the room. VOC levels were the same at the different sampling locations when the size of the room was below 10 m². However, field measurements and statistical analyses showed that when the size of the room increased, the most evenly distributed VOCs can be measured most reliably in the vicinity of the exhaust terminal device or in the exhaust air.

在这项研究中，对 47 个病房的挥发性有机化合物 (VOC) 进行了测量，以确定室内 VOC 的最合适采样位置。另一个目标是找出医院环境中最主要的 VOC 及其每建筑面积的排放量。同时从每个房间抽取三个样本：一个来自房间的中心，一个来自靠近墙壁的地板，一个来自排气终端。VOCs 的浓度在所有情况下都相对较低，最丰富的化合物是十甲基环戊硅氧烷、d-柠檬烯、二甲苯和 2-甲基-2-丙醇。单位建筑面积主要化合物的平均排放率在 49 至 81 µg/m ²之间变化H。统计分析表明，房间面积和体积对采样位置之间的总挥发性有机化合物 (TVOC) 浓度的影响不同。排气末端的浓度高于房间地板和中间的样品。当房间面积小于10 m ²时，不同采样点的VOC 水平相同。然而，现场测量和统计分析表明，当房间的大小增加时，可以最可靠地测量排气末端装置附近或排气中分布最均匀的 VOC。
