Poor indoor air quality can lead to a range of health problems, from minor irritations to more serious conditions such as respiratory diseases, heart disease, and even cancer. Improving indoor air quality is essential for creating a healthier indoor environment and reducing the risk of indoor air pollution-related health issues.

Common Sources of Indoor Air Pollution

Indoor air pollution can originate from various sources commonly found in indoor environments. Some of the most prevalent sources include tobacco smoke, which introduces harmful chemicals like carbon monoxide and particulate matter into the air. Household activities such as cooking, using cleaning products, and operating gas stoves can release volatile organic compounds and nitrogen dioxide. Additionally, building materials, furnishings, and insulation may emit organic chemicals, while biological pollutants like mold, pet dander, and pollen can also contribute to poor indoor air quality. Another common source of indoor air pollution is the burning of solid fuels such as crop waste, dung, charcoal, and coal for cooking and heating in households. Awareness of these common sources is crucial for implementing effective strategies to minimize indoor air pollution and safeguard human health.

Major Pollutants in the Indoor Environment

Particulate matters are tiny particles suspended in the air, consisting of dust, dirt, and smoke. These can originate from outdoor air, tobacco smoke, cooking activities, and indoor sources like candles and fireplaces. Volatile Organic Compounds (VOCs)

VOCs are emitted as gases from certain solids or liquids and include various chemicals, some of which may have short and long-term adverse health effects. Common sources of VOCs include paints, varnishes, cleaning supplies, and building materials.

Particulate Matters

Particulate matters, also known as PM, are tiny particles of solid or liquid droplets suspended in the air. In indoor environments, these can originate from various sources such as cooking, smoking, burning candles, and operating fireplaces, as well as indoor activities. Additionally, outdoor air can intrude and contribute to particulate matters indoors. PM can vary in size and composition, with fine particles being more concerning as they can penetrate deep into the lungs and enter the bloodstream, leading to serious health effects. It's crucial to address particulate matters in indoor air as they are associated with respiratory diseases, cardiovascular issues, and even premature death. Effective ventilation and air purification techniques play a vital role in reducing PM levels indoors.

Volatile Organic Compounds (VOCs)

Volatile organic compounds (VOCs) are chemicals that vaporize at room temperature, commonly found in many indoor sources such as building materials, paints, and cleaning products. These compounds can have short- and long-term health effects, including eye, nose, and throat irritation, as well as headaches and nausea. Some VOCs are known to cause damage to the liver, kidneys, and central nervous system. Moreover, certain VOCs are classified as carcinogens, posing a risk of cancer after prolonged exposure. Reducing VOC emissions involves using low-VOC products, increasing ventilation, and utilizing air purifiers with VOC filters to improve indoor air quality. Understanding and managing VOC levels, especially those from new furniture, is crucial for maintaining a healthy indoor environment.

Nitrogen Oxides (NOx)

Nitrogen oxides (NOx) are a group of highly reactive gases formed when fuel is burned at high temperatures, common in indoor settings. Sources include gas appliances, tobacco smoke, and car exhaust. NOx can irritate the lungs, lower immunity to respiratory infections, and aggravate asthma. Long-term exposure may lead to an increased risk of respiratory conditions and cardiovascular diseases.
