作为学校哮喘管理计划合作伙伴的一部分，使用环境观察清单和Q-TRAK室内空气质量监测仪从德克萨斯州东南部60所小学的385个房间收集了环境数据。从20所学校的80间教室的地板、地毯和区域地毯中收集用于过敏原分析的灰尘样本。在86%的房间中发现二氧化碳水平> 1，000 ppm; 69%的室内湿度高于建议水平。在20%的房间中，Der p I尘螨过敏原水平> 2，000 ng/g，但只有2.5%的房间的Der f I螨过敏原水平超过推荐的公差。在所有学校中发现了可检测水平的蟑螂过敏原（Bla g II）（中位数为5.5 ng/g），其中10%的房间超过了建议的阈值。几乎三分之二的教室的霉菌孢子计数> 10，000 col/g（中位数，14，400 col/g;范围，2，000 - 52，000 col/g）。
As part of the Partners in School Asthma Management Program, environmental data were collected from 385 rooms in 60 elementary schools in southeast Texas, using an Environmental Observation Checklist and a Q-TRAK Indoor Air Quality Monitor. Dust samples for allergen analysis were collected from floors, carpets, and area rugs in 80 classrooms in a subset of 20 schools. CO2 levels >1,000 ppm were found in 86% of rooms; 69% had indoor humidity above recommended levels. Der p I dust mite allergen levels >2,000 ng/g were present in 20% of rooms, but only 2.5% of rooms had Der f I mite allergen levels exceeding recommended tolerances. Detectable levels of cockroach allergen (Bla g II) were found in all schools (median 5.5 ng/g), with 10% of rooms over the recommended threshold. Almost two-thirds of classrooms had mold spore counts > 10,000 col/g (median, 14,400 col/g; range, 2,000 - 52,000 col/g).
