What Do Mean By Indoor Air Pollution ?

Air pollution is caused both indoors and outdoors. Most people think that pollution is caused only in the outdoor environment and in heavily crowded areas. When they are in the house, they are safe. However, this is not at all true because air pollution can be caused in any place, including indoors and we are the main reasons for causing it also.

What Causes Pollution ?

When pollutants enter the environment, be it water, soil, atmosphere or water, and end up making the environment unsuitable for living organisms, then it is termed as pollution. Chemicals, heat, light, noise, smoke and fumes are all pollutants. Sometimes, some pollutants like heavy metals are naturally present in the environment but in low levels.
