Indoor air quality is a growing concern because we spend the majority of our time indoors, whether in schools, offices, gyms, shopping malls, or factories. Yet, many people overlook it and its associated adverse health effects. Contaminated indoor air quality can lead to several acute and chronic health problems, including cardiovascular, respiratory, and neurological problems.
Several factors influence indoor air quality, including occupancy, pollutants, building design, and the type of external environment, such as urban or rural areas. In this blog post, we will have an in-depth comparison and discussion of the indoor air quality challenges faced in urban versus rural settings.
Indoor Air Quality Challenges in Urban Settings
Urban areas pose different challenges in maintaining good and safe indoor air. Let’s explore a few of them.
- Emissions from vehicles and trucks worsen air quality in urban areas. Nitrogen oxides, carbon monoxide, and particulate matter are emitted from vehicles and infiltrate indoor spaces, worsening air quality and leading to several health issues.
- Industrial emissions from power plants and factories contain particulate matter, acid-forming gases, and greenhouse gases. These gases are harmful and pollute both indoor and outdoor environments.
- The street canyon effect, a phenomenon in which tall buildings flank urban streets, creating a canyon-like environment, is also a common contributor to poor air quality in urban settings. These tall structures alter temperature and airflow, trapping pollutants and hindering dispersion.
- Fine particulate matter is highly prevalent in urban settings. These ultra-fine particles can penetrate deep into the bloodstream and cause lung problems.
- Urban cities have tightly packed spaces. Indoor air pollutants are released as a result of using disinfectants, cleaning agents, and adhesives. Their frequent use in schools, homes, and healthcare facilities releases volatile organic compounds (VOCs) and can cause lung problems, headaches, liver damage, and loss of coordination.
- Many buildings in large cities have limited ventilation. This leads to pollutants, airborne viruses, bacteria, and mould being trapped within the space at higher concentrations.
Conclusively, it can be said that urban settings expose their dwellers to pollutants that are often present in higher concentrations.
Indoor Air Quality Challenges in Rural Settings
- You may think that rural areas have naturally clean air because of their lower number of vehicles and reduced industrial emissions. You are certainly mistaken — the reality is worse than you might expect. It is because:
- Many households in rural regions rely on biomass and domestic fuels for cooking and heating purposes. Incomplete combustion of these fuels causes indoor air quality to degrade.
- A research study conducted in China suggests that approximately 80%–90% of total exposure to particulate matter in rural areas is attributed to the use of biomass and solid fuels in homes.
- Rural towns are home to a country’s agricultural activities. Such activities cause chemical drift from pesticides and fertilisers, affecting the air quality in nearby regions. Moreover, farming operations such as soil tillage also spread dust and coarse particles that infiltrate indoor spaces and degrade air quality.
- Bushfire smoke also affects rural regions. While such areas experience higher concentrations during these events, there is usually enough open space for air to circulate and dilute pollutants. However, both outdoor and indoor air quality in rural areas may be severely affected due to their proximity to bushfires.
- While there is more open space for natural ventilation, it alone cannot improve indoor air quality. Mechanical ventilation is still required for maximum efficiency. However, rural areas lack access to advanced air filtration technology, leaving people dependent on methods that are often insufficient.
So, What’s the Solution?
Air purifiers help improve air quality by trapping harmful and fine contaminants, resulting in fresher air. They pass indoor air through high-efficiency filters that capture even the smallest particles using a mesh. Some air purifiers feature activated carbon filters to eliminate toxic gases and odorous substances from the environment.
Using advanced methods such as UV and photocatalysis maximises filtration efficiency and provides cleaner indoor air.
While disparities exist for underprivileged communities that do not have access to cleaner air, addressing the issue and advocating for equality is essential.
