Air PollutionGoing Green 2 What is air pollution?What causes it:factories,cars,rubbish,cleaning products,insect sprays,high temperatures,fumes from cooking/ cigarettes/paint? Clean Air at HomeAir pollution doesn’t just come from factories and our cars. We also cause it at home with the products we use and the way we live. Air indoors can be polluted by cleaning products, dust, paint, insect, sprays, cigarette smoke or steam from cooking. We often need to keep doors and windows closed to keep the insides of our houses cool in the summer or warm in the winter. This traps pollutants and can make places for insects, dust mites and mould to live. Some pollutants such as smoke and insect sprays can cause breathing problems such as asthma, especially for those people who are allergic to dust. To reduce air pollution at home you should open the doors and windows 2-3 times a day, use natural cleaning products, and do not allow smoking.
