When some air pollutants from particulate matter and gases contaminate the air in the Indoor areas, Indoor air pollution occurs. In this article, we have discussed the causes of indoor air pollution that you should be aware of,

INDOOR AIR POLLUTANTS YOU SHOULD BE AWARE OF

1. RADON GAS

Radon, a colorless, odorless gas that is radioactive in nature, is the primary source of indoor air pollution. This colorless gas is usually found in the basement of the homes. This is because it migrates downwards due to its high density. It is quite hard to detect this gas due to its colorless and odorless nature.

2. VOLATILE ORGANIC COMPOUND

Volatile organic compounds, commonly called, as VOC, are the compounds that easily convert to a gaseous state. VOCs are emitted from paints, solvents, preservatives used for wood, air fresheners, dry cleaners, and pesticides. It is observed that the concentration of VOC is higher in indoor air as compared to that of the outdoor air.

3. FORMALDEHYDE

Formaldehyde is a very commonly found indoor air pollutant found in all homes & buildings. It is a colorless gas having a pungent odor. It is important to note that Formaldehyde has a carcinogenic effect. The familiar sources of Formaldehyde are the compressed wood products, consumer products like nail polish and wallpaper, household appliances like a wood stove, kerosene stove, and most importantly, tobacco products.

4. NITROGEN OXIDE & NITROGEN DIOXIDE

It should be noted that there are seven different oxides of nitrogen that are found indoor. However, the two oxides of nitrogen that are majorly found indoor are Nitrogen Dioxide and Nitric Oxide. The most common sources of these oxides of nitrogen are unvented combustion appliances, the smoke of tobacco products, and kerosene stoves.

5. CARBON MONOXIDE

It is impossible to see, taste, or smell the presence of this toxic gas. The primary sources of carbon monoxide are unvented kerosene heaters and leaking chimneys along with the smoke of the tobacco products.

6. BIOLOGICAL MATTER

Biological contaminants include bacteria, the saliva of pets, dust particles, mites as well as cockroaches. The stored water, which is standing for long-time and wet surfaces, breeds molds and bacteria. In addition to that, carpets and beds and other areas where the dust collects are the sources of biological contaminants.

7. AMMONIA We are exposed to this colorless gas with a pungent odor by inhaling it in the form of gasoline or vapor. Most of Ammonia emitted in the indoor areas is from the cleaning products.

8. TRICHLORORTHYLENE

Trichloroethylene, commonly known as TCE, is a colorless liquid that is volatile in nature. People working in the factories or living nearby the factory in which TCE are the ones who are mostly exposed to it. Other than that, the contaminated soil also contributes to indoor air pollution, as TCE that is present in the soil enters homes through cracks that are formed in the foundation.

9. BENZENE

Benzene that is present in the indoor air originates from the air that is outdoors along with the indoor sources like construction material, compressed wood furniture, heating, and cooling systems.

10. PARTICULATE MATTER

Particulate matter is nothing but the mixture of solid particles and liquid particles that are suspended in the air. This particulate matter can vary in size, shape, and composition.

Now that you are very well aware of the various indoor air pollutants that cause pollution in the indoor spaces, work towards having a fresh and clean breath of air, because indoor air pollution has several detrimental effects on our body, which we will discuss in our next article.
