Study Of The Major Pollutants In The Classroom In The Air

Research on Indoor Air Quality has been developed for many years inside and outside country. But there is few specialized study on Classroom Air Quality. Students spend most of their time in classroom, which is a primary place for daily study. The air inside classroom imposes important impact on students' growth and health. As students are viewed as the nation's future, study on classroom air-pollution has significant meaning.Till now there are no integrated regulations on classroom air quality in the world. There is no all-around research on classroom air quality. Many researches just focus on one or several pollutants. In China, the researches mainly concentrate on carbon dioxide in classroom of elementary school and middle school. There is few study on pollution caused by decoration inside classroom and pollutant sources outside classroom.Using other researchers' work for reference, after analyzing more pollutants inside classroom such as formaldehyde, benzene, toluene, dimethylbenzene, ammonia, radon, sulfur dioxide, nitrogen dioxide, carbon monoxide, carbon dioxide and inhalation particle, etc, a few countermeasures and suggestions have been brought forward to improving the air quality inside classroom in the thesis.The thesis contributes to the complementary study on classroom air quality. It is a constructive exploration for establishment of classroom air quality regulations.
