Outdoor Factors Affecting Indoor Air Quality

Indoor air quality is impacted by outdoor factors like pollutants, temperature, humidity, bacteria, and ventilation. Other crucial influences include dust, bioaerosols, and CO2 levels. Additionally, factors such as lighting, noise, and odors play a role in maintaining a healthy indoor environment.

Factors Affecting Indoor Air Quality:

– Ventilation and air flow rate play crucial roles in maintaining indoor air quality.

– Pollutants, temperature, humidity, bacteria, and thermal comfort are key factors to consider.

– Chemicals, dust, bioaerosols, as well as carbon dioxide levels are significant determinants.

– Lighting, noise level, and odors can also impact indoor air quality.

– The school’s micro location and distance from pollution sources, like traffic, are vital outdoor factors.

Practical Ways To Improve Indoor Air Quality

Indoor air quality is influenced by several factors including ventilation and air flow rate. Proper ventilation plays a crucial role in improving indoor air quality as it helps to remove pollutants and odors while maintaining a comfortable temperature and humidity level. Switching to home-made cleaning solutions is another practical way to minimize the emission of volatile organic compounds (VOCs) that can affect air quality. Limiting dust and pollen by regularly cleaning surfaces and using water to wipe dusty areas can also help improve indoor air quality. Avoiding newly painted buildings for a few weeks can prevent exposure to high levels of VOCs. Keeping workplaces clean and dust-free is important to combat sick building syndrome and ensure the well-being of employees. Additionally, using dehumidifiers and air purification systems can help control humidity and remove airborne contaminants, further enhancing indoor air quality.

Major Sources Of Indoor And Outdoor Air Pollution

The 5 main factors that affect indoor air quality are ventilation, air flow rate, pollutants, temperature, humidity, and thermal comfort. Chemicals, dust, bioaerosols, and carbon dioxide also play important roles. In addition, lighting, noise levels, and various odors can impact indoor air quality. In terms of outdoor sources, factors such as the school’s micro location, distance from potential sources of pollution, and traffic are crucial in affecting indoor air quality. Major indoor sources of air pollution include cooking activities, paints and varnishes, and furniture adhesives. Similarly, outdoor sources such as vehicle emissions, industrial pollutants, and natural sources contribute to compromising human health due to poor air quality.

Impact Of Air Pollution On Human Health

Impact of Air Pollution on Human Health: Indoor air quality plays a crucial role in human health, especially in densely populated urban areas. Effect on the Respiratory System: Poor air quality can lead to respiratory issues such as asthma and bronchitis, particularly in children and the elderly. Carcinogenic Effects: Long-term exposure to indoor air pollutants like radon and formaldehyde can increase the risk of cancer. Other Health Effects: Indoor air pollution can also cause headaches, dizziness, and fatigue, affecting overall well-being.
