We usually think of air pollution as being outdoors, but the air in our classrooms could also be polluted. Sources of indoor pollution include Mold and pollen and other household products and carbon monoxide Materials used in the building such as asbestos; formaldehyde can be the cause of the illness sometimes it cannot be found. Usually, indoor air quality problems only cause discomfort. Most people feel better as soon as they remove the source of the pollution. Our project will map out all the classrooms in our school, first focusing on one. The first classroom will be one with no windows for ventilation. We will make sure that the building is better ventilated and have plants to get rid of pollutants which can improve the quality of indoor air.
