Abstract Contaminants of biological origin, such as fungi and bacteria, are ubiquitous inside the residences and especially in bedroom microenvironments. Epidemiological studies have shown that fungal exposure is associated with respiratory and allergic symptoms. Infants and young children comprise a susceptible population to study, since they spend most of their day inside their rooms. A study was undertaken to investigate environmental factors (temperature and relative humidity), indoor pollutants (PM2.5, CO2), building characteristics and occupant activities in relation to the spectrum and levels of settled fungi in 25 Greek young's children bedrooms, and to evaluate the fungal qualitative and quantitative composition of houses with and without asthmatic/allergic children. In this context, on-site house inspections to study the Indoor Air Quality (IAQ) in bedrooms of young children below three years of age were conducted in Athens, Greece. Sampling campaigns were conducted over one-week period using Electrostatic Dust Collectors (EDCs) to quantify fungal and bacterial exposure in settled dust and real-time monitoring techniques for environmental parameters (T, RH, CO2, PM2.5). The present investigation revealed that the predominant dustborne genus was Cladosporium followed by Alternaria and Aspergillus, and that living in a suburban area, the presence of an attached garage and the presence of a carpet in the bedroom were significant predictors of fungal concentrations. Furthermore, although the difference was not statistically significant, higher fungal concentrations were recorded in the houses with asthmatic or atopic children.

希腊雅典幼儿卧室的室内空气质量和粉尘生物污染物

摘要 生物源污染物，如真菌和细菌，普遍存在于住宅内部，尤其是卧室微环境中。流行病学研究表明，真菌暴露与呼吸道和过敏症状有关。婴幼儿是学习的易感人群，因为他们一天中的大部分时间都在房间里度过。进行了一项研究，调查环境因素（温度和相对湿度）、室内污染物（PM2.5、CO2）、建筑特征和居住者活动与 25 间希腊儿童卧室中定居真菌的光谱和水平的关系，并评估有和没有哮喘/过敏儿童的房屋的真菌定性和定量组成。在这种情况下，在希腊雅典进行了现场房屋检查，以研究三岁以下幼儿卧室的室内空气质量 (IAQ)。使用静电集尘器 (EDC) 进行了为期一周的采样活动，以量化沉降灰尘中的真菌和细菌暴露量以及环境参数（T、RH、CO2、PM2.5）的实时监测技术。目前的调查显示，主要的尘传属是枝孢菌属，其次是链格孢菌和曲霉属，居住在郊区、附设车库和卧室地毯是真菌浓度的重要预测因素。此外，虽然差异没有统计学意义，但在有哮喘或特应性儿童的房屋中记录到更高的真菌浓度。
