Air pollution does not take place exceptionally when the industrial gases are emitted into the atmosphere. Pollution can be much more mundane thing than we think. Furniture, household appliances, and materials used in construction of buildings can emit toxic fumes and sufficiently worsen the quality of air in the building.
Mold and dust are the most common indoor air pollutants. Dust regularly penetrates into the building through doors and windows. If the building lacks wet cleaning, dust that stocks everywhere is inhaled by the inhabitants in large amount which contributes to the respiratory diseases and may cause an allergy. Mold appears in poorly ventilated rooms. It is characteristic to the buildings that rarely see the sunshine so that the moist cannot completely dry out. Inhabitants can ignore mold and dust in their homes, however, respiratory conditions are inevitable for them.
Tobacco smoke is another substance common to a great number of homes. Smoking indoors leaves a lasting imprint on our apartments that is quite difficult to remove. Smoke penetrates into all soft furniture as well as into wallpapers and remains here for years. Toxic fumes continue to emit all the time until the furniture is taken away.
Major indoor pollutants shall be avoided where it is possible, otherwise, ventilation and air cleaners shall be actively used. It is important to keep chemicals in separate non-inhabited rooms that close tightly to prevent inhabitants from inhaling them. Some pollutants such as radon (a gas emitted by the breakdown of uranium) are impossible to remove using air cleaners. From this perspective, it would be easier to remove the source that emits pollutants. In general, paying closer attention to the surrounding objects we can prevent ourselves from allergies and cancer.
