Air quality and health
Air pollution is a major environmental health problem that affects people in low-, middle-, and high-income countries. According to the National Institutes of Health, air pollution causes approximately 6.5 million deaths worldwide each year, and this number is rising. The World Health Organization (WHO) reports that in 2019, 99% of the world's population lived in areas where the air quality did not meet their guidelines, with 4.2 million premature deaths attributed to outdoor air pollution. The burden of these deaths disproportionately affects people in low- and middle-income countries, with 89% of premature deaths occurring in these regions.
The two most common types of pollution that cause health problems are ozone and particle pollution. Ozone is a colorless gas that occurs naturally when sunlight interacts with oxygen, but it is also released by burning fossil fuels from motor vehicles, factories, and industrial facilities. It can accumulate at ground level, forming smog, and hot, sunny weather can increase its buildup. Particle pollution refers to microscopic solid material or droplets suspended in the air, which can come from car exhaust, tires, dust storms, volcanic eruptions, chemical aerosols, farming, construction, building demolition, fireplaces, and wildfires.
Both short-term and long-term exposure to air pollutants can cause a variety of health issues. When inhaled, pollutants can enter the bloodstream and contribute to coughing, itchy eyes, and the development or worsening of many breathing and lung diseases, leading to hospitalizations, cancer, or premature death. People with asthma, heart disease, or chronic obstructive pulmonary disease (COPD) are especially vulnerable to the effects of air pollution, which can trigger attacks or cause wheezing and coughing. Children are also particularly at risk, with studies suggesting that exposure to air pollution is linked to premature birth and potential impacts on brain development.
To protect yourself from poor air quality, it is advisable to stay indoors and use air filters or adjust the air conditioning/heating system to recirculate air instead of drawing it from outside. If you must go outside, wear an N95 mask approved by the National Institute for Occupational Safety and Health (NIOSH) to protect against smoke particles. Avoid cooking, especially frying or grilling, which can increase indoor air pollution. Do not smoke, and refrain from using fireplaces, candles, or incense. Keep up to date with local air quality forecasts and alerts, and ensure you have a supply of any necessary medications.
To address air pollution and improve public health, concerted action is required from local, national, and regional policymakers in sectors such as energy, transport, waste management, urban planning, and agriculture. The WHO's Air Quality and Health Unit works across knowledge, evidence, institutional capacity building, and leadership to support reducing air pollution levels and protecting populations from health risks. Implementing policies that promote cleaner transport, energy-efficient homes, improved power generation, and better waste management practices can significantly reduce outdoor air pollution.

Wildfires and smoke
Wildfires can have a significant impact on the air quality in your area. The smoke from wildfires can carry harmful pollutants, including fine particulate matter (PM2.5 and PM10), ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2), and carbon monoxide (CO). These pollutants can have adverse effects on human health, particularly for individuals with respiratory conditions such as asthma.
To check the pollution level in your area due to wildfires, you can utilize online tools such as AirNow.gov, which provides a Fire and Smoke Map. This interactive map offers real-time data on air quality, allowing you to assess the impact of wildfire smoke in your specific location. By entering your geographic information, you can view the extent to which wildfire smoke is affecting the air quality in your vicinity.
Additionally, there are other resources available to monitor air pollution levels. The World Air Quality Index (WAQI) project provides a global perspective on air pollution. Through their online platform, you can access real-time air quality data for specific cities worldwide. The GAIA air quality monitor, utilized by WAQI, employs laser particle sensors to measure PM2.5 and PM10 particle pollution levels, providing detailed information on one of the most harmful types of air pollutants.
It is important to stay informed about the pollution levels in your area, especially during wildfire season. By using tools like the AirNow Fire & Smoke Map and the WAQI platform, you can make informed decisions to protect your health and well-being. These resources enable you to understand the potential risks associated with wildfire smoke and take necessary precautions, such as limiting outdoor activities or using air purifiers indoors.
Being proactive in monitoring wildfire smoke and its impact on air quality is crucial for safeguarding your health. By regularly checking the pollution levels in your area, you can make informed choices to minimize your exposure to harmful pollutants. This proactive approach can help you breathe easier and maintain your respiratory health, especially if you have pre-existing conditions affected by poor air quality.

Ozone and PM
To find out the pollution level in your area, you can use the Air Quality Index (AQI), which is available on AirNow.gov. This index tells you how clean or polluted your outdoor air is and provides information on any associated health effects. The AQI uses numbers and colours to help people understand when to take action to protect their health.
PM, on the other hand, refers to a mixture of solid particles and liquid droplets found in the air. Some of these are large enough to be seen, such as dust, dirt, soot, or smoke, while others are so small they can only be detected with an electron microscope. PM2.5, which are fine inhalable particles with diameters of 2.5 micrometres or less, pose the greatest risk to health. They are small enough to get deep into your lungs and can even enter your bloodstream, causing tissue damage, lung inflammation, and a range of adverse health effects, especially in children and older adults with pre-existing heart or lung diseases.
PM10, which includes particles with diameters of up to 10 micrometres, can also be harmful. While they are more likely to deposit on the surfaces of the larger airways in the upper region of the lung, long-term exposure to PM10 has been linked to respiratory mortality. Both PM2.5 and PM10 are monitored by the Air Quality Index and can be found in real-time on the World Air Quality Index map.
To reduce air pollution and improve air quality, the EPA has implemented national and regional rules to limit emissions of pollutants that form ground-level ozone and PM. These include vehicle and transportation standards and reviews of the NAAQS (National Ambient Air Quality Standards).

Air Quality Index (AQI)
The Air Quality Index (AQI) is a tool developed by the EPA to communicate about outdoor air quality and health. It is a simple, uniform way to report daily air quality conditions. The AQI is calculated by converting measured pollutant concentrations to a uniform index based on the health effects associated with a pollutant. The health benchmarks used for calculating the AQI are pollutant-specific and are established by the EPA through the National Ambient Air Quality Standards. The Clean Air Act requires the EPA to review these standards every five years.
The AQI is divided into six color-coded categories, each corresponding to a different level of health concern. An AQI value of 50 or below represents good air quality, while an AQI value over 300 represents hazardous air quality. When the AQI value is predicted to exceed 101, an air quality alert is issued, warning that the conditions may be harmful to those sensitive to air pollution.
AQI forecasts heavily depend on temperatures, precipitation, wind, and cloud cover. Weather affects pollution creation and transport from other areas. For example, ozone is formed by a chemical reaction between nitrogen oxides and volatile organic compounds in the air, and hot, sunny weather speeds up the process. Similarly, high humidity or pressure, strong overnight temperature inversions, or low wind speeds can cause fine particle pollution to increase. Fine particles are emitted from cars or other pollution sources but are also created in reactions between sulfur oxides, nitrogen oxides, and ammonia in the air.
To improve air quality, individuals can take several actions. These include reducing waste emissions by composting food and garden items, recycling, reusing bags, and disposing of trash through local collection. Using public transportation, carpooling, biking, or walking can also help minimize vehicle emissions. Conserving energy by turning off lights and electronics when not in use, and using energy-efficient appliances can contribute to improved air quality. Additionally, individuals should be mindful of air pollution levels in their area and follow guidance from authorities to protect their health when necessary.
