Man-made mineral fibers (MMMF) and other airborne dusts were measured in 105 rooms in a representative sample of public buildings, excluding rooms with physically damaged boards or buildings with notable indoor climate problems. There were no differences in the MMMF concentrations with respect to the type of binder. The average concentrations ranged from 17 to 210 respirable MMMF/m3. The average concentrations of the reference group was intermediate and therefore indicated that sources other than ceiling boards contributed to the obtained values. No grouping by concentration of MMMF on cupboards was possible. Airborne concentrations of respirable MMMF were 2.7 times lower in rooms with mechanical ventilation than in rooms with natural ventilation. For nonrespirable MMMF, the most important factor was the quality of the cleaning. The concentration in poorly cleaned rooms was 5.5 times that of well-cleaned rooms. Ventilation, quality of cleaning, and number of persons affected the non-MMMF and total dust concentrations.
在公共建筑的代表性样本中的105个房间内测量了人造矿物纤维（MMMF）和其他空气传播灰尘，不包括有物理损坏板材的房间或存在明显室内气候问题的建筑物。MMMF浓度在粘合剂类型方面没有差异。平均浓度范围为17至210可吸入MMMF/立方米。参考组的平均浓度处于中间水平，因此表明天花板板材以外的来源导致了所获得的值。无法按橱柜上MMMF的浓度进行分组。机械通风房间内可吸入MMMF的空气传播浓度比自然通风房间低2.7倍。对于不可吸入MMMF，最重要的因素是清洁质量。清洁不善的房间中的浓度是清洁良好房间的5.5倍。通风、清洁质量和人数影响了非MMMF和总灰尘浓度。
