The amounts of dust, protein, and allergens in vacuumed floor covering samples taken from both schools and homes in Norway have been investigated. Classrooms contained significantly more crude dust per unit area than homes, while the mean protein content per unit area was somewhat higher in homes. The main allergen exposure problem in classrooms was that of pet allergens; the contents of dog allergens and the major cat (Felis domesticus) allergen Fel d I per unit area were significantly higher in school classrooms than in homes of families who do not keep pets. The mite and food allergens, on the contrary, were more prevalent in homes. Carpeted floors in schools and homes contained significantly more dust, proteins, and allergens than smooth floors (P < 0.05). Fel d I was detected in the vacuum cleaners' filter system in concentrations from < 1 ng to 1080 ng, confirming that this allergen can pass through the dust bag during vacuuming.
对从挪威学校和家庭采集的真空吸尘地板覆盖物样本中的灰尘、蛋白质和过敏原含量进行了调查。教室每单位面积的粗灰尘含量明显高于家庭，而家庭每单位面积的平均蛋白质含量略高。教室中主要的过敏原暴露问题是宠物过敏原；学校教室每单位面积的狗过敏原和主要猫（家猫）过敏原Fel d I的含量明显高于不养宠物家庭的家中。相反，螨虫和食物过敏原在家庭中更为普遍。学校和家庭中的地毯地板比光滑地板含有明显更多的灰尘、蛋白质和过敏原（P < 0.05）。在真空吸尘器的过滤系统中检测到的Fel d I浓度从< 1 ng到1080 ng，证实这种过敏原在吸尘过程中可以穿过集尘袋。
