Small airports are often in densely populated areas, increasing health risks
Small airports are often situated in densely populated areas, which raises concerns about the health risks for residents. The proximity of these airports to residential neighbourhoods means that millions of people live close to significant sources of air pollution.
Airports are among the largest sources of air pollution in the United States. For example, Los Angeles International Airport (LAX) is the largest source of carbon monoxide (CO) in California. Carbon monoxide is a dangerous, invisible, odourless gas that can cause serious health issues, especially for infants, the elderly, and those with pre-existing respiratory conditions. Aircraft emissions contribute to the greenhouse effect and climate change, with aviation estimated to account for 5% of the gases causing anthropogenic climate change.
In addition to carbon monoxide, aviation gasoline used in small propeller planes and some helicopters contains lead (Pb), a toxic heavy metal that can adversely affect multiple human organ systems, including the nervous, immune, and cardiovascular systems. Areas around small airports show higher levels of lead pollution, putting nearby residents at risk.
Airports also contribute to noise pollution, which can be a source of stress and health problems for those in the vicinity. Furthermore, airport emissions contain nano-sized particles that can reach the lower airways upon inhalation, leading to potential respiratory and cardiovascular issues. Studies have linked exposure to airport emissions to increased risks of pre-term birth and decreased lung function.
The impact of small airports on air quality and health risks is a significant concern, and ongoing research is vital to address these issues and develop strategies for sustainable aviation and the well-being of surrounding communities.

Airports are among the largest sources of air pollution in the United States. For instance, Los Angeles International Airport is the largest source of carbon monoxide (CO) in the state of California. Airports also contribute to noise pollution, which can have a significant impact on the health of those living in the vicinity, including airport employees.
Small airports, in particular, are typically located in more densely populated areas. Research has shown that areas around small airports have higher levels of Pb (lead) pollution. Lead is a toxic heavy metal that can adversely affect the nervous system, immune system, kidney function, and cardiovascular system. It can also interfere with the reproductive and developmental systems.
Air pollution has been linked to an increased risk of cardiovascular issues. Fine particulate matter (PM2.5) in the air can increase the risk of cardiovascular events, especially in those with pre-existing conditions. Air pollution can cause the stiffening of arteries, increased blood coagulability, and the buildup of plaques in blood vessels over time.
Noise pollution from airports can also contribute to cardiovascular issues. It can cause stress, anger, and annoyance during waking hours, leading to increased oxidative stress and inflammation, which are damaging to cardiovascular health. Additionally, noise pollution can disrupt sleep cycles, which are crucial for maintaining cardiovascular health.
Overall, the combination of air and noise pollution from airports can have a detrimental effect on cardiovascular health, and it is important to address these issues to reduce the impact on individuals and populations living nearby.

Airports are among the largest sources of air pollution in the US
Airports are among the largest sources of air pollution in the United States. Commercial airport activity can negatively impact the air quality in the areas surrounding airports, and millions of Americans live close to major airports. For example, Los Angeles International Airport (LAX) is the largest source of carbon monoxide in California. The average taxi time for planes at LAX increased by 23% from 1995 to 2007, leading to significantly higher levels of local ambient air pollution.
Small airports, which are often located in more densely populated areas, also contribute to air pollution. Research has shown that areas around small airports have higher levels of lead (Pb) pollution due to the use of leaded gasoline in small propeller planes and some helicopters. Lead is a toxic heavy metal that can adversely affect the nervous, immune, and cardiovascular systems, as well as interfere with reproductive and developmental processes.
In addition to lead pollution, airport emissions contain volatile organic compounds, particulate matter, and nano-sized particles that can reach the lower airways upon inhalation. These emissions have been linked to adverse health effects, including cardiovascular disease and cancer. Airport particles have also been shown to induce DNA damage and generate similar levels of ROS as traffic emission particles.
Noise pollution from aircraft is another significant issue for people living near airports and airport employees. Excessive aircraft noise can cause health problems and stress for those in the vicinity. Furthermore, aviation emissions contribute to climate change, with aviation accounting for an estimated 5% of the gases that contribute to anthropogenic climate change.
Overall, the high levels of air pollution and noise pollution caused by airports have serious health and environmental implications, making air quality a critical challenge for the aviation industry to address as it strives for sustainable mobility in the future.

Aviation emissions contribute to climate change
Aviation emissions have a significant impact on climate change, contributing to the greenhouse effect and global warming. While aviation accounts for approximately 2.5% of global CO2 emissions, its overall contribution to climate change is higher due to the emission of other gases and pollutants.
Aircraft emissions at cruising altitudes, including water vapour, soot, sulfates, and nitrogen and sulfur oxides, have a significant impact on the atmosphere. Water vapour from aircraft exhausts, known as contrails, account for the largest share of aviation's contribution to warming. Soot particles, or black carbon, in combination with hydrocarbon particles, contribute to contrail-induced cirrus clouds, which have a major impact on climate change. Additionally, aviation emissions affect the concentration of atmospheric gases, leading to a short-term increase and long-term decrease in ozone and methane levels.
The impact of aviation on climate change is further exacerbated by the growth in air travel and freight. In 1960, only 100 million passengers travelled by air, compared to 4.56 billion in 2019. This rapid increase in air travel demand has resulted in a corresponding rise in aviation emissions.
Furthermore, aviation is one of the most challenging sectors to decarbonize. Unlike other industries that are transitioning to low-carbon alternatives, aviation heavily relies on fossil fuels. While improvements in energy efficiency have been made, with a halving of energy usage per passenger-kilometre since 1990, the increase in demand offsets these gains.
To meet sustainability commitments and reduce the impact of aviation on climate change, a multifaceted approach is necessary. This includes improving energy efficiency, transitioning to low-carbon fuels, and exploring alternatives such as hydrogen and electric power. Additionally, addressing ground service equipment and airport service vehicle emissions, which contribute to local air quality and climate change, is crucial.

Air quality measurement systems can help define gases and particles present
Small airports are typically located in more densely populated areas. Research has shown that areas around small airports have higher levels of Pb pollution. Lead (or Pb) is a toxic heavy metal that can adversely affect the nervous system, immune system, kidney function, and cardiovascular system. It can also interfere with the reproductive and developmental systems.
Air quality measurement systems are essential to define the gases and particles present at airports. These systems employ various sensors and technologies to detect and measure different pollutants. For instance, optical sensors are used to detect particulate matter (PM) by measuring the amount of light scattered by the particles as air passes through a beam of light. The light scattering is caused by the concentration of particulates, and the detector's algorithm converts this pattern into particulate size and amount.
Another technology used in air quality measurement systems involves metal oxide semiconductors. These systems measure the conductivity of the semiconductor, which changes when a gas interacts with it through oxidation or reduction. This change in conductivity is detected by sensors, which then output the gas concentration. This technology is used to measure gases like nitrogen dioxide, ozone, and carbon monoxide.
Volatile organic compounds (VOCs), which include many volatile gases, are detected using photoionization technology. VOC detectors indicate the general amount of VOCs present rather than identifying specific gases. Carbon dioxide measurements are also crucial, as they inform operators about the air quality and oxygen levels.
By employing these air quality measurement systems, airports can identify the specific pollutants they emit and understand how these pollutants affect nearby inhabited areas. This information is vital for implementing measures to reduce pollution, protect the environment, and ensure healthy working conditions for employees.
