Abstract

Indoor air quality refers to the air quality in and around laboratory buildings and facilities, which directly affects the health and comfort of workers. Poor air quality poses numerous health challenges to the laboratory workers and environment, and causes sick building syndrome (SBS) among workers. The objective of this study is to determine associations of SBS related to indoor air concentration in a dose-dependent manner among Nigerian laboratory university workers. This was a cross-sectional study on a population-based sample of Nigerian university laboratories and the workers. Data were collected using an indoor air quality control meter, dosimeter tubes gases of interest, and a set of questionnaires (MM-40). The results showed that the mean indoor air concentrations in a dose-dependent manner for chemical parameters range from 473.0 ppm to753.0 ppm, 17.9 ppm to 27.3 ppm, 5.7 ppm to 8.5 ppm, and 6.3 ppm to 9.1 ppm for CO2 , CO, NO2, H2S and SO2 , respectively. The prevalence of SBS, i.e., skin-related syndrome (SRS) is 38.5%, general-related symptom (GRS) is 28.3%, mucosal-related symptom (MRS) is 19.2% and at least one score was a respiratory-related symptom (RRS), which is 13.9%. The significant associated factors of SBS revealed by multinomial logistic regression in this study were NO2 [SRS (P = 0.022), GRS (P = 0.023), MRS (P = 0.032)], H2 S [SRS (P = 0.031), GRS (P < 0.001), MRS (P = 0.021)], and SO2 [SRS (P = 0.001), GRS (P < 0.001), MRS (P = 0.022)]. On the other hand, office laboratory temperature and relative humidity were shown to be negatively statistically associated with prevalence symptoms relative to RRS. In this study, SBS was found to be high. Indoor air concentration Air Quality and SBS Syndrome 180 in a dose-dependent manner and environmental parameters could increase the prevalence and incidence of SBS-related symptoms. Therefore, it is important to educate the workers on occupational and environmental health at a workplace to minimise SBS in the future.

尼日利亚实验室大学工作人员的室内空气质量和病态建筑综合症

室内空气质量是指实验室建筑物和设施内部及其周围的空气质量，直接影响到工作人员的健康和舒适。恶劣的空气质量给实验室工作人员和环境带来了许多健康挑战，并导致工人患上病态建筑综合症(SBS)。本研究的目的是确定尼日利亚实验室大学工作人员中与室内空气浓度有关的SBS的剂量依赖关系。这是一项以尼日利亚大学实验室和工作人员为样本的横断面研究。数据收集使用室内空气质量控制仪、剂量计管感兴趣的气体和一套问卷(MM-40)。结果表明，室内空气中CO2、CO、NO2、H2S和SO2的平均浓度分别为473.0 ppm ~ 753.0 ppm、17.9 ppm ~ 27.3 ppm、5.7 ppm ~ 8.5 ppm和6.3 ppm ~ 9.1 ppm，化学参数呈剂量依赖性。SBS的患病率，即皮肤相关综合征(SRS)为38.5%，全身相关症状(GRS)为28.3%，粘膜相关症状(MRS)为19.2%，至少有一个评分为呼吸相关症状(RRS)，占13.9%。多项logistic回归分析结果显示，SBS的显著相关因素为NO2 [SRS (P = 0.022)、GRS (P = 0.023)、MRS (P = 0.032)]、H2 S [SRS (P = 0.031)、GRS (P < 0.001)、MRS (P = 0.021)]和SO2 [SRS (P = 0.001)、GRS (P < 0.001)、MRS (P = 0.022)]。另一方面，办公室实验室的温度和相对湿度在统计上与RRS相关的流行症状呈负相关。在这项研究中，SBS被发现是高的。空气质量与SBS综合征180呈剂量依赖性，环境参数可增加SBS相关症状的患病率和发病率。因此，重要的是对工人进行工作场所职业和环境卫生教育，以尽量减少今后的SBS。
