Preventing Pneumonia: Reducing Air Pollution's Deadly Impact

Air pollution is a leading cause of pneumonia, a respiratory disease that affects people of all ages, particularly children and the elderly. According to the World Health Organization (WHO), household air pollution, caused by the use of polluting fuels and stoves for cooking, is a significant contributor to pneumonia, especially in low- and middle-income countries. Outdoor air pollution, from sources such as vehicles, industrial activities, and power plants, also plays a major role in the incidence of pneumonia. To reduce the rate of pneumonia due to air pollution, it is essential to address both indoor and outdoor sources of pollution, improve access to clean fuels and technologies, and implement policies that prioritize the reduction of air pollution-related pneumonia deaths, especially in vulnerable populations.

Reducing indoor air pollution

Exposure to indoor air pollution increases the risk of pneumonia, especially in children under five. Globally, it accounts for about a million deaths, with 44% of all pneumonia deaths in children under five being attributed to household air pollution.

To reduce indoor air pollution, you can take several measures. Firstly, eliminating or reducing individual sources of pollution is crucial. For example, switching to cleaner fuels and technologies for cooking, such as solar, electricity, biogas, liquefied petroleum gas (LPG), natural gas, or alcohol fuels, is recommended by the WHO. Avoid using polluting fuels like kerosene, wood, charcoal, or coal, which generate harmful pollutants.

Secondly, adequate ventilation plays a vital role in improving indoor air quality. Opening windows, when feasible, encourages a healthy exchange of indoor and outdoor air. Mechanical ventilation systems, such as outdoor air intakes associated with HVAC systems, can also be employed to enhance ventilation.

Thirdly, certain behaviours can contribute to indoor air pollution. Smoking, for instance, severely impacts respiratory health and should be avoided indoors. If you have pets, maintaining their hygiene and keeping them out of bedrooms can reduce allergy-causing dander. Minimizing the use of scented products, air fresheners, and scented cleaning products is also advisable, as they can react with ozone to form particles and formaldehyde.

Additionally, some design choices can inadvertently increase indoor air pollution. Minimize carpeting, as it can trap pollutants like dust mites, pet dander, and mould spores. Opt for hard-surface flooring instead. If carpets are used, ensure they are labelled with the Carpet and Rug Institute (CRI) Green Label Plus logo. When purchasing building materials or composite wood furnishings, look for labels indicating California Phase II Compliant or TSCA Title VI Compliant.

Lastly, proper storage of chemicals is essential. Keep solvents, glues, and pesticides away from living areas, and opt for homemade cleaning products, such as a mixture of white vinegar and water, whenever possible.

Limiting exposure to PM2.5

Exposure to PM2.5, or fine particulate matter, is a significant health risk, particularly for those with pre-existing heart or lung conditions, pregnant women, children, and older adults. PM2.5 is a mixture of solid and liquid particles suspended in the air, and due to their small size, they can travel deeply into the respiratory tract, reaching the lungs. This can cause a range of adverse health effects, including eye, nose, throat, and lung irritation, coughing, sneezing, a runny nose, and shortness of breath. Prolonged exposure to high levels of PM2.5 has been linked to an increased risk of heart disease, asthma, low birth weight, and premature death.

To limit exposure to PM2.5, several measures can be implemented, particularly focusing on indoor air quality, as this is where individuals spend most of their time. Here are some strategies to reduce PM2.5 exposure:

• HEPA Filters and Air Purifiers: Using high-efficiency particulate air (HEPA) filters in ventilation systems and air purifiers is an effective way to remove PM2.5 particles from indoor air. HEPA filters are designed to capture fine particles, including PM2.5, and can significantly improve indoor air quality.
• Closing Windows in Highly Polluted Areas: In areas with high outdoor air pollution, keeping windows closed can help reduce the ingress of PM2.5 particles into indoor spaces. This is especially important when the outdoor PM2.5 levels exceed 35 μg/m3, as recommended by the Environmental Protection Agency (EPA).
• Clean Fuels and Technologies: Transitioning to cleaner fuels and technologies for household energy needs can significantly reduce PM2.5 emissions. The World Health Organization (WHO) recommends solar power, electricity, biogas, liquefied petroleum gas (LPG), natural gas, alcohol fuels, and biomass stoves that meet emission targets. Avoiding the use of kerosene and unprocessed coal can also help reduce PM2.5 levels.
• Addressing Indoor Sources: Indoor activities such as cooking, frying food, burning candles, using fireplaces, and operating fuel-burning space heaters can contribute to PM2.5 levels indoors. It is essential to use proper ventilation when performing these activities and ensure that indoor spaces are well-ventilated to reduce the concentration of PM2.5.
• Community-Level Actions: On a larger scale, community-level actions can include implementing policies to reduce vehicle emissions, regulating industrial activities that contribute to air pollution, and promoting the use of cleaner energy sources. These measures can help reduce outdoor PM2.5 levels and improve air quality for entire communities.

By implementing these strategies, individuals and communities can effectively limit their exposure to PM2.5, thereby reducing the associated health risks, including pneumonia, and improving overall respiratory and cardiovascular health.

Using clean fuels and technology

The use of clean fuels and technology is essential to reduce household air pollution and protect health. This includes a shift towards cleaner energy sources such as solar, electricity, biogas, liquefied petroleum gas (LPG), natural gas, and alcohol fuels. These alternatives are much safer and healthier compared to traditional solid fuels like wood, crop waste, charcoal, coal, and dung, which are major contributors to indoor air pollution.

The World Health Organization (WHO) has issued guidelines for indoor air quality, specifically addressing household fuel combustion. These guidelines provide evidence-based recommendations on the types of fuels and technologies that can be considered clean. For instance, the guidelines discourage the use of kerosene and unprocessed coal due to their negative impact on health. Instead, they emphasize the adoption of cleaner alternatives that meet emission targets to ensure benefits for both health and the environment.

One of the most effective ways to reduce air pollution and decrease the rate of pneumonia is to transition to clean household energy solutions for cooking, heating, and lighting. This involves providing access to affordable and clean energy sources for households, especially in low- and middle-income countries where solid fuel usage is still prevalent. Financial support and policies that promote the adoption of cleaner technologies and fuels can help achieve this transition. Additionally, improved ventilation and housing design can also reduce indoor air pollution levels.

Clean technologies and fuels play a crucial role in reducing industrial smokestack emissions, a significant source of outdoor air pollution. The implementation of pollution control measures in the design and construction of new industrial facilities is essential to ensure a cleaner industrial base. For example, the use of combustion technologies with strict emission controls can reduce the environmental impact of waste incineration. Capturing methane gas emitted from waste sites and utilizing it as biogas is another effective strategy to reduce air pollution and promote the use of cleaner fuels.

The transportation sector is another major contributor to air pollution. To address this, policies and investments should focus on promoting cleaner transport options, such as electric vehicles, and encouraging the development and adoption of more fuel-efficient vehicles. This includes setting fuel economy standards for passenger vehicles and heavy-duty trucks, as well as promoting the use of cleaner heavy-duty diesel vehicles and low-emissions vehicles and fuels, such as those with reduced sulfur content. These measures will not only reduce air pollution but also lead to significant cost savings and reduced oil consumption.

Reducing outdoor air pollution

Policy Changes for Clean Fuels and Technologies: Governments play a pivotal role in reducing outdoor air pollution by implementing policies that promote access to clean fuels and technologies. The World Health Organization (WHO) has issued guidelines for indoor air quality, discouraging the use of kerosene and unprocessed coal. These guidelines also specify emission rate targets to safeguard health. Additionally, the transition to clean energy sources like solar power, electricity, biogas, and liquefied petroleum gas (LPG) can significantly mitigate outdoor air pollution.

Targeted National Strategies: Countries heavily impacted by air pollution-related pneumonia deaths should prioritize targeted strategies. This includes introducing policies that address the leading causes of air pollution-related pneumonia and protecting the most vulnerable populations. For example, the Every Breath Counts Coalition urges national governments to adopt a target of reducing air pollution-related pneumonia deaths by 50% by 2030. This involves increasing access to clean cooking fuels and technologies and reducing average PM2.5 exposure.

Multi-Sectoral Collaboration: Establishing a multi-sectoral and multi-governmental Clean Air Taskforce can drive progress in reducing outdoor air pollution. This task force should include representatives from various ministries, such as health, energy, agriculture, industry, and urban development. By coordinating efforts across sectors, countries can develop comprehensive strategies to tackle outdoor air pollution effectively.

Addressing Industrial and Vehicular Sources: Outdoor air pollution is significantly influenced by industrial activities and vehicular emissions. Regulations and emission standards for industries and vehicles can help curb the release of harmful pollutants into the atmosphere. This includes enforcing stricter emission standards for coal-burning power plants and implementing cleaner technologies in industrial processes. Additionally, promoting sustainable transportation options, such as electric vehicles or public transportation, can contribute to reducing vehicular air pollution.

International Cooperation: Pneumonia-related deaths due to outdoor air pollution are a global concern, affecting countries in Africa, Asia, and Latin America. International cooperation is essential to sharing best practices, technological advancements, and scientific knowledge to combat this issue. By working together, countries can develop more effective strategies, allocate resources efficiently, and support each other in implementing solutions to reduce outdoor air pollution and its impact on pneumonia rates.

By implementing these measures, we can significantly reduce outdoor air pollution, protect vulnerable populations, and decrease the rate of pneumonia worldwide.
