在塞尔维亚诺维萨德的五个丝网印刷设施中检测到室内空气样本中存在甲醛。在每个丝网印刷设施的一个工作周内，对空气进行五次采样。在4小时内连续进行取样。甲醛的浓度通过UV-VIS光谱法在580 nm处测定。甲醛的平均浓度范围为0.413至0.836 ppm。将检测到的浓度水平与0.75 ppm（OSHA标准）和0.016 ppm（NIOSH标准）的允许暴露限值进行比较，结果表明，设施5中的平均甲醛浓度分别是规定值的1.11倍和52.25倍。
The presence of formaldehyde in indoor air samples has been detected in five screen printing facilities of Novi Sad, Serbia. Air was sampled five times during one working week for each screen printing facility. The sampling was conducted continuously during 4 hours. The concentrations of formaldehyde were determined by UV-VIS spectrometry at 580 nm. The average concentrations of formaldehyde were in the range from 0.413 to 0.836 ppm. Comparison of the detected concentration levels with the permissible exposure limit of 0.75 ppm (the OSHA standard) and 0.016 (the NIOSH standard) indicated that the average formaldehyde concentration in facility 5 was 1.11 and 52.25 times higher than prescribed values, respectively.
