Our study assessed the exposure to formaldehyde of Romanian school children in relation to the classroom indoor environment characteristics and respiratory and allergic symptoms reported in a questionnaire survey, using the data collected in the SINPHONIE (Schools Indoor Pollution and Health: Observatory Network in Europe) project. Measurements of formaldehyde and microclimate parameters were conducted in three classrooms per school, in five schools, together with one outdoor measurement at each school. Questionnaires were used to collect information on classroom characteristics and health effects among children. The indoor formaldehyde levels for a school week varied between 15.5 and 66.2 μg/m, with a median value of 34.8 μg/m. The adjusted odds ratios for allergy-like, asthma-like, and flu-like symptoms were 3.23 (95% CI 1.31-8.00), 2.69 (95% CI 1.04-6.97), and 2.39 (95% CI 1.04-5.50), respectively, when exposed to higher formaldehyde levels (≥ 35 μg/m) during a school week, compared to lower formaldehyde level exposure (< 35 μg/m). Higher levels of indoor formaldehyde were significantly associated with health symptoms in children. The high indoor formaldehyde levels were related to the use of water-resistant paint for ceiling coverings, moisture damage signs, and lower classroom natural ventilation rates.
本研究评估了罗马尼亚学童在与教室室内环境特征相关的甲醛暴露水平，以及问卷调查中报告的呼吸和过敏症状，使用了 SINPHONIE（学校室内污染与健康：欧洲观察网络）项目中收集的数据。在五所学校的每所学校的三间教室中进行了甲醛和微气候参数的测量，并在每所学校进行了一次室外测量。使用问卷收集有关教室特征和儿童健康影响的信息。一周内学校室内甲醛水平在 15.5 到 66.2μg/m 之间，中位数为 34.8μg/m。当一周内暴露于较高水平的甲醛（≥35μg/m）时，过敏样、哮喘样和流感样症状的调整比值比分别为 3.23（95%CI 1.31-8.00）、2.69（95%CI 1.04-6.97）和 2.39（95%CI 1.04-5.50）。与较低水平的甲醛暴露（<35μg/m）相比。室内甲醛水平较高与儿童健康症状显著相关。高浓度的室内甲醛与用于天花板覆盖物的防水油漆、潮湿损坏迹象以及较低的教室自然通风率有关。
