摘要在这个案例研究中，医院工作人员确实患有与室内空气质量差有关的症状。为了调查症状的原因，进行了MM 40-调查和房屋检查方法。该研究包括49个手术室和470名员工。MM-40调查显示，超过40%的员工患有皮肤反应，超过50%的员工患有上呼吸道症状，25%的员工患有头痛。在工作场所的结构研究中没有发现员工症状的原因。房间平均换气次数为5.51次/h。共采集了61种材料和49个室内空气样本。材料样品中最常见的化合物是2-乙基-1-己醇和脂肪烃。一些材料样本的挥发性有机化合物排放量很高，据推测，这是在一些房间中观察到的工人症状的一个原因。然而，在大多数情况下，室内空气VOC浓度较低。根据线性回归模型，地板材料的排放量不能解释室内空气中VOCs的浓度。其中一个原因是房间的高通风率，这可能使室内的VOC水平较低。此外，室内VOC浓度与医院正在进行的医疗活动密切相关。
ABSTRACT In this case study, hospital workers did suffer from symptoms related to the poor indoor air quality. To investigate reasons for symptoms MM40-survey and house inspection methods were performed. The study consisted of 49 operating rooms and 470 employees. MM-40 survey revealed that over 40% of the staff suffered from skin reactions, over 50% had upper respiratory tract symptoms and 25% suffered headaches. No reason for the staff’s symptom could be found in the structural studies of workplaces. The mean air exchange rate of the rooms was 5.51/h. In total 61 materials and 49 indoor air samples were taken. The most frequently found compounds in the material samples were 2-ethyl-1-hexanol and aliphatic hydrocarbons. VOC emissions were high in some of the material samples and they presumably were the one reason for the workers’ symptoms observed in some in of the rooms. However, indoor air VOC concentrations were low in most of the cases. According to the linear regression model emissions from flooring material couldn’t explain the indoor air concentration of the VOCs. One reason for that was the high ventilation rates of the rooms, which presumably kept VOC levels in indoors low. In addition, VOC concentrations indoors were strongly related to the ongoing healthcare activities in the hospital.
