Indoor Pollution

Indoor air quality deserves great attention as the air quality in our homes, schools and workplaces contains both natural and human made impurities which can affect the health and comfort of the occupants.

Causes of Indoor Pollutions

CHEMICAL POLLUTANTS like VOC’s (Volatile Organic Compounds like formaldehyde, benzene and xylene) – are emitted from building materials, office equipments carpets, paints and furniture. It is also found in household and cleaning products.

BIOLOGICAL POLLUTANTS - Air borne particles include allergens, such as Bacteria, fungi, virus, dust mites, pet dander, mold and dust.

SMOKE - The secondhand smoke (ETS) exhaled by smokers and the burning end of the cigarette, cigar n pipes gives out smoke which contains harmful chemicals and gases -that pollutes the air.

RADON It is a radioactive gas that occurs naturally in the soil; it is the top cause of lung cancer.

NO PROPER VENTILATION AND IMPROPER MAINTENANCE OF CENTRAL HEATING AND AIR CONDITIONING SYSTEM. It can cause pollutants like CARBON MONOXIDE and carbon dioxide remains indoors. Fresh air should circulate frequently or else the pollutants could do more harm.

ELECTRONIC DEVICES Electronic devices like laser printers and photocopiers both at home and office are sources of indoor pollution. When in use they emit chemical particles that can cause respiratory damage. Studies have found chemical concentrations were higher in office dust than in house dust.

COMBUSTION POLLUTANTS It comes from heat sources or fuel-burning appliances like wood stoves, water heaters and dryers which include both particles and odorless, colorless gases. Among these gases are nitrogen dioxide and carbon monoxide,, which causes irritation and shortness of breath.

The air we breathe contains harmful pollutants which affect our physical and mental health. If a house or office is new or renovated the pollution index is quite high. Research studies undertaken by NASA prove that houseplants are effective at improving indoor air quality by filtering the air and increasing the level of oxygen.
