Protecting Our Health From Air Pollution's Impact

Air pollution is a major environmental health problem that affects people in low-, middle-, and high-income countries alike. It is caused by the burning of fossil fuels, vehicle exhaust, wildfires, and more. The health impacts of air pollution are significant, with numerous studies showing that increased levels of fine particulate matter in the air correspond to increased hospitalizations for heart disease, stroke, diabetes, pneumonia, and other serious health problems. To minimize the health impacts of air pollution, individuals can take precautions such as checking air quality forecasts and limiting outdoor activities when pollution levels are high, reducing energy use, and opting for renewable energy sources. Governments and organizations also play a crucial role in implementing policies and programs to reduce air pollution and protect public health.

Check daily air pollution forecasts and limit outdoor activities when levels are high

Minimizing exposure to air pollution is essential for protecting your health and well-being. One crucial step is to regularly check daily air pollution forecasts and adjust your outdoor activities accordingly, especially when pollution levels are high. Here's how you can do this:

Check Air Quality Index (AQI) Forecasts

The Air Quality Index (AQI) is a helpful tool developed by the Environmental Protection Agency (EPA) to measure and communicate daily air quality. It provides a standardized way to understand air quality across different regions. The AQI is typically calculated for major pollutants regulated by the Clean Air Act, including ozone, particle pollution, carbon monoxide, nitrogen dioxide, and sulfur dioxide. You can access the AQI for your specific location through websites like AirNow.gov, which offers hourly updates and forecasts for the coming days.

Understand the Color-Coded System

The AQI uses a color-coded system to indicate the level of air quality. These colors correspond to specific categories, with statements explaining the potential health impacts and recommended actions for each level. For example, green typically indicates good air quality, while orange represents moderate air quality, and red or purple denotes unhealthy levels. Understanding these color codes can help you quickly interpret the AQI and make informed decisions about your outdoor activities.

Limit Outdoor Activities During High Pollution

When the AQI indicates high levels of air pollution, it's essential to limit your time outdoors, especially for children and individuals with respiratory or cardiovascular conditions. Avoid outdoor exercises during these periods, as physical activity can increase the amount of pollution you inhale. Instead, opt for indoor workouts, such as using a gym or walking in a shopping mall. If you must go outside, consider wearing a mask, as certain types like N95 masks can filter out fine particles.

Plan Outdoor Activities Strategically

Utilize the AQI forecasts to plan your outdoor activities when pollution levels are expected to be lower. Many AQI forecasts provide a "forecast discussion," indicating when pollution levels are predicted to be highest and lowest during the day. By checking these forecasts, you can schedule your outdoor plans accordingly. Additionally, even when the AQI is in the healthy range, avoid exercising near high-traffic areas, as vehicle emissions can still create high pollution levels in those areas.

Protect Indoor Air Quality

While limiting outdoor activities during high pollution is essential, it's also crucial to ensure that the air inside your home is clean. Indoor air quality can be affected by outdoor pollutants, as well as indoor sources such as carbon monoxide from certain appliances and radon gas. Take steps to reduce indoor pollutants, such as installing a carbon monoxide detector, properly ventilating your home, and maintaining any fireplaces or wood-burning stoves.

Reduce energy use and switch to energy-efficient appliances

Energy use and the burning of fossil fuels are major contributors to air pollution. By reducing energy use, you can help improve air quality, curb greenhouse gas emissions, and encourage energy independence.

One way to reduce energy use is to switch to energy-efficient appliances. Energy-efficient appliances use less energy over their service lives while maintaining performance and quality. For example, washing machines with load sensing and temperature control, dryers with moisture sensors and automatic shut-off, refrigerators with automatic defrost and temperature control, dishwashers with soil sensors and delayed start, and dehumidifiers with automatic shut-off and adjustable humidity control. These appliances can provide long-term benefits by lowering overall electricity demand, reducing the need for new electricity generation, and helping to stabilize electricity costs.

Another way to reduce energy use is to opt for renewable energy sources. For instance, solar-powered water heaters or wind-powered generators can utilize clean and renewable energy to operate, reducing your carbon footprint and dependence on fossil fuels.

Additionally, you can make small changes in your daily life to reduce energy use. This includes turning off electronics when they are not in use, adjusting temperature settings, and setting timers. You can also choose to walk, bike, or carpool instead of driving, and buy local produce to cut down on global shipping and transportation that contribute to air pollution.

By reducing energy use and switching to energy-efficient appliances, you can not only save money on utility bills but also contribute to a cleaner and healthier planet.

Avoid burning wood, trash, or other materials that contribute to particle pollution

Burning wood, trash, or other materials releases harmful chemicals into the environment, which can have serious health implications. Backyard trash burning is particularly harmful, as it releases chemicals that persist in the environment, polluting the air, food, lakes, and streams. Burning residential trash from a single home has been found to release more dioxin into the air than an industrial incinerator.

Wood smoke is also a major contributor to air pollution. Campfires, residential fireplaces, and wood stoves all release toxic chemicals when they burn wood. These include nitrogen oxides, sulfur dioxide, volatile organic chemicals (VOCs), and polycyclic organic matter (POMs). Burning plastic and treated wood releases heavy metals and toxic chemicals such as dioxin, arsenic, and furans. These chemicals can cause eye and nose irritation, breathing difficulties, coughing, headaches, and nausea. People with heart disease, asthma, emphysema, or other respiratory diseases are especially vulnerable to these air pollutants.

To minimize the health impacts of particle pollution from burning, it is important to avoid burning trash, such as garbage, plastic, old furniture, or construction materials like treated wood products or particle board. Instead, opt for composting, mulching, recycling, or other garbage disposal options. For those who use wood stoves or fireplaces, it is crucial to ensure they are properly installed, regularly swept, and maintained. To reduce pollution, increase chimney height, ensure an adequate oxygen supply by keeping the flue open, and burn only clean, dry, untreated, unpainted wood.

Newer, EPA-approved wood stoves and fireplaces can significantly reduce pollution levels. Compared to older models, they emit 85% less smoke and pollution and require 30% less wood to operate. Additionally, it is important to be aware of and comply with state and local burning laws and regulations. For example, Wisconsin's Administrative Code NR 429.04 prohibits burning specific materials, and New York has banned all open burning with some exceptions.

Wear masks that filter fine particles, such as N95s, when outdoors in polluted areas

Masks are highly effective against air pollution, especially in environments with a high risk of exposure to harmful airborne infections, such as shared office spaces, classrooms, and public places. When outdoors in polluted areas, it is important to wear masks that filter fine particles, such as N95s, KN95s, or FFP2 masks. These masks are rated for their ability to filter out at least 95% of airborne particles larger than 0.3 microns, which includes most PM2.5 particles. N99 masks are also available and can filter out 99% of airborne particles, which may be preferable for sensitive individuals.

It is important to ensure a good fit and seal on your mask to maximize its effectiveness. The suction of a good seal should be visible, causing the paper to bend inwards and create a concave surface on flexible, disposable masks. For masks with a firm plastic construction, you should be able to prevent airflow by covering the filters with your hand. The key to any mask's effectiveness is ensuring that there is no unfiltered airflow around the edges of the mask.

In addition to wearing masks, there are other ways to minimize the health impacts of air pollution. One way is to check daily air pollution forecasts and air quality indexes in your area to determine when to take extra precautions. During periods of high pollution, it is recommended to limit outdoor activities, especially near traffic-congested areas, and to stay indoors with closed windows, using air conditioners and fans to stay cool if necessary.

Another way to reduce your exposure to air pollution is to use alternative forms of transportation, such as walking, biking, carpooling, or taking public transportation instead of driving your car. Burning firewood and trash are also major sources of particle pollution, so it is important to avoid burning these materials and to limit the use of fireplaces and wood stoves, especially during the winter when they contribute significantly to smog.
