Common Indoor Air Pollutants

We are all aware that the outside air we breathe contains contaminants. But we won’t realize that indoor air also has pollutants that can be more dangerous than outdoor air. Most of us spend our time indoors, where these pollutants can exist, which can cause health issues, especially for people who are already having health concerns. In this article, we will explore all the common indoor air pollutants that need to be avoided in our homes.

What is an Indoor Air Pollutant?

Indoor air pollutants may contain harmful gases and tiny particles released from materials inside and around a home. The pollutant level in the air will depend on factors like ventilation, heat, and moisture. The higher the concentration of pollutants, the more health risk you face.

90% of Americans spend their time indoors, and pollutant concentrations are higher indoors than outdoors. Without proper ventilation, pollutants can build up and reach harmful levels. In recent years, indoor air pollution has increased mainly due to synthetic materials in building supplies and personal care products. Energy-efficient buildings are designed to reduce airflow between indoors and outdoors.

Affect of Indoor Air Pollutants on Health

Indoor air pollutants can cause short and long-term illness. Various factors influence indoor air pollutant exposure. The illness depends on the person’s existing health, the air quality, the surroundings, and the pollutant concentration in the air.

• Short-term: Short-term illness can be similar to flu or cold. Other symptoms include irritation of the eyes, nose, and throat, dizziness, fatigue, and headaches.
• Long-Term: Short-term effects gradually decrease with the decrease in pollutant concentration. But when exposed for longer periods, there are high chances of developing health issues like Asthma, COPD, heart disease, and cancer.

Common Indoor Air Pollutants

Excess Moisture

Moisture is a major indoor pollutant that is often unnoticed. It affects people’s health and the building’s condition. Common moisture issues occur when warm, humid air touches a cold surface like a mirror, window, or wall. Since cooler air holds less moisture, the extra water turns into droplets on the surface. These damp areas lead to mold, mildew, and dust mites, which can cause asthma, allergies, or material damage like wood and metal. High humidity indoors can also release harmful chemicals from furniture or cleaning products into the air.

Radon

Radon is a radioactive gas that forms naturally in the soil and can seep into homes from the ground. It is the second leading cause of lung cancer in the U.S. Radon levels in buildings can differ depending on the location. A simple system with a small fan and PVC pipes can be used to reduce radon levels. This system lowers the pressure in the soil and sends out the radon-rich air outside.

Volatile Organic Compounds (VOCs)

VOCs are substances that evaporate into the air from things like building materials, furniture, gasoline, pesticides, and even cooking. They also include body odors. While many VOCs are harmless, some, like formaldehyde, can harm health even at low levels.

Tobacco Smoke

Smoking is known for its harmful effects on health. It produces large amounts of harmful gases and particles, making it one of the most damaging activities for both indoor air quality and health.

Biological Contaminants

Biological contaminants are living organisms that grow in damp areas or places with dust and debris. These include bacteria, viruses, pollen, mold, insects, pet dander, and dust. They can cause allergies and spread illnesses like the flu, measles, and chickenpox. Maintaining indoor humidity under control helps reduce the growth of these contaminants.

Carbon Monoxide

Carbon monoxide is a colorless, odorless gas produced while burning fossil fuels. Appliances like heaters, stoves, furnaces, fireplaces, and gas-powered tools can release carbon monoxide if not properly used or maintained. When exposed to low levels, it can cause tiredness. High levels can lead to chest pain, vision problems, and mild brain issues.

Pesticides

Pesticides are always toxic and come in forms like sprays, liquids, powders, and sticks. According to the EPA, a study found that at least 75% of American households use an indoor pesticide. Most pesticide exposure happens indoors, with some homes having levels of around 12 different pesticides.

Nitrogen Dioxide

Nitrogen dioxide (NO2) is a reactive gas produced by burning fossil fuels. Breathing in NO2 can harm the respiratory system and is related to heart and lung damage. It can also increase the risk of pregnancy issues, neurological and kidney damage, autoimmune disorders, and cancer.
