[-3:13.00]Indoor Air Quality Problems
[-3:14.00]Generally speaking,
[-3:15.00]a school has far more occupants per square metre than an office building.
[-3:16.00]The fact is that with an increasing urbanization,
[-3:17.00]the student population in many schools is still growing.
[-3:18.00]Therefore,an awareness of possible indoor air quality problems
[-3:19.00]is important for teachers and students alike.
[-3:20.00]Most indoor air pollution in schools comes from sources inside the school building
[-3:21.00]For example,photocopiers,manufactured wood products like desks and chairs
[-3:22.00]and carpeting cleaning products and pesticides
[-3:23.00]may all emit harmful elements into the air.
[-3:24.00]Other pollutants may also accumulate
[-3:25.00]in specific areas such as laboratories and toilets.
[-3:26.00]Meanwhile,outdoor air that enters a school building through windows
[-3:27.00]and other openings can also bring vehicle exhausts into the classrooms.
[-3:28.00]Outdated ventilation systems in some older schools
[-3:29.00]increase the risks of indoor air quality problems.
[-3:30.00]Poor indoor air quality can cause serious respiratory problems.
[-3:31.00]Younger students in particular are affected.
[-3:32.00]Children's respiratory systems are still developing
[-3:33.00]They are more sensitive to the air pollutants.
[-3:34.00]Children also have higher respiration rates than adults.
[-3:35.00]As a result,they are likely to inhale more of the pollutants than adults do
[-3:36.00]There is a lot that we can do and should do.
[-3:37.00]For instance,increasing ventilation rates,banning smoking,
