Albuquerque's Air Pollution: A Dire Situation And Solutions

The air quality in Albuquerque, New Mexico, is a pressing issue for its residents, with the city facing challenges due to high levels of air pollutants, including ground-level ozone, smoke, blowing dust, and particulate matter. The city's terrain, situated in a valley surrounded by mountains, contributes to lighter winds and more stagnant air, exacerbating the temperature inversion effect, which traps cold, polluted air under a layer of warmer air. While Albuquerque has achieved a good annual mean Air Quality Index (AQI) since 2000, short-term pollution spikes and certain seasons can pose health risks, particularly to sensitive groups.

Albuquerque's air quality is generally good, but pollution spikes still pose health risks

Albuquerque's air quality is generally good, with annual means falling within the "good" Air Quality Index (AQI) category since at least 2000. The AQI, developed by the Environmental Protection Agency (EPA), calculates air quality based on six major air pollutants: ozone (O3), PM2.5, PM10, carbon monoxide (CO), sulfur dioxide (SO2), and nitrogen dioxide (NO2). Despite Albuquerque's overall healthy air quality, short-term pollution spikes still pose health risks to residents, particularly those with respiratory conditions.

Albuquerque's terrain, nestled in the Albuquerque Basin valley and surrounded by mountains, contributes to lighter winds and more stagnant air. This natural barrier, coupled with temperature inversions, leads to elevated PM2.5 levels and overall AQI values during the winter months. The temperature inversion effect occurs when warmer air traps colder, polluted ground-level air, preventing the dispersion of air pollution.

Wood burning, building heating, car idling, and agricultural and construction activities contribute to increased emissions and dust particles in the air during the winter. These factors, along with temperature inversions, result in the city's infamous ""brown cloud." While wood burning is not prohibited, the city encourages limiting this practice to protect air quality.

The months from November to February tend to be the most polluted, with pollution levels up to two times higher than in the summer. Summer months, from April to August, present challenges with ozone formation due to the necessary presence of sunlight and heat. Ground-level ozone is one of the two pollutants that pose the greatest threat to human health in the country.

To address air pollution, Albuquerque has implemented various control measures. These include vehicle emissions testing, oxygenated fuels programs, and the wintertime NO-BURN program, which has improved visibility and reduced carbon monoxide levels. The city also encourages the use of alternative transportation, such as walking, bicycling, and carpooling, to reduce vehicle emissions and congestion. Overall, while Albuquerque's air quality is generally good, pollution spikes and specific seasonal patterns can still impact the health of residents, especially those sensitive to air pollution.

Ozone, PM2.5, PM10, carbon monoxide, sulfur dioxide, and nitrogen dioxide are the six major air pollutants

Ozone (O3), PM2.5, PM10, carbon monoxide (CO), sulfur dioxide (SO2), and nitrogen dioxide (NO2) are the six major air pollutants that the Air Quality Index (AQI) takes into account. The AQI is a tool used by the EPA to report air quality and indicate the level of concern regarding air pollution. It is calculated by weighting these six major air pollutants based on their threat to human health.

Since 2000, Albuquerque has consistently achieved an annual mean in the "good" AQI category, with values below 50, indicating little to no risk to human health. However, short-term pollution spikes can still pose health risks to residents. For example, Albuquerque's ozone levels received a failing grade in the American Lung Association's 2019 "State of the Air" report due to an excessive number of unhealthy ozone days.

Ozone is a significant concern in Albuquerque, with the city currently ranking worst for ozone pollution among all US EPA criteria pollutants. Ozone formation is influenced by sunlight and heat, which react with precursor pollutants. This explains why ozone levels are typically higher during the summer months from April to August. Mobile sources, such as emissions from cars, trucks, and planes, are the largest single contributor to Albuquerque's ozone challenges.

PM2.5, or fine particulate matter, is another critical air pollutant in Albuquerque. Wildfires, wood-burning stoves, and temperature inversions can lead to spikes in PM2.5 levels, particularly during the winter months. Temperature inversions occur when warm air traps colder air below, preventing the dispersion of air pollution. This phenomenon is exacerbated by Albuquerque's terrain, which creates a natural barrier that contributes to lighter winds and more stagnant air.

Carbon monoxide (CO), sulfur dioxide (SO2), and nitrogen dioxide (NO2) are also considered major air pollutants in Albuquerque. While specific data on these pollutants in Albuquerque is limited, it is important to note that they are included in the AQI calculation and contribute to the overall air quality assessment.

High levels of ground-level ozone and airborne particles pose the greatest threat to human health

The air quality in Albuquerque, New Mexico, is generally considered "good" according to the Air Quality Index (AQI), which weighs six major air pollutants for their threat to health: ozone (O3), PM2.5, PM10, carbon monoxide (CO), sulfur dioxide (SO2), and nitrogen dioxide (NO2). However, high levels of ground-level ozone and airborne particles pose the greatest threat to human health in the area.

Ozone is a major concern for Albuquerque's air quality, and the city has experienced a high number of unhealthy ozone days. In 2019, the American Lung Association's "State of the Air" report gave Albuquerque a failing grade due to exceeding the federal allowance of 3.2 unhealthy ozone days. From 2016 to 2018, the city experienced an average of 6.3 unhealthy ozone days. The formation of ground-level ozone requires sunlight and heat to react with precursor pollutants. This reaction is exacerbated during the summer months from April to August, when higher temperatures and sunlight are more prevalent.

The city's geography also contributes to the air pollution problem. Albuquerque lies in a valley known as the Albuquerque Basin, surrounded by mountains and mesas that create a natural barrier, leading to lighter winds and more stagnant air. This terrain, coupled with temperature inversions, results in elevated PM2.5 levels and overall AQI values during the winter months. Temperature inversions occur when a warmer air layer traps colder, polluted ground-level air, preventing the dispersion of air pollution.

Wood burning, vehicle emissions, and dust from dusty roads and construction activities are significant sources of air pollution in Albuquerque. The city has implemented control measures, such as vehicle emissions testing and oxygenated fuels programs, to reduce carbon monoxide pollution. Additionally, Albuquerque's metropolitan transportation plan encourages alternative transportation methods to reduce the number of vehicles on the road and, consequently, vehicle emissions.

The health effects of air pollution can be immediate, particularly for sensitive groups such as individuals with respiratory conditions, children, and the elderly. During periods of high air pollution, sensitive individuals may experience coughing, breathing difficulties, chest pain, and throat irritation. To mitigate these health risks, residents are advised to limit their time spent outdoors and reduce physical exertion during periods of high air pollution.

Wood burning, building heating, and car idling are the primary sources of wintertime pollution

While Albuquerque has achieved a “good” annual mean in the Air Quality Index (AQI) category since at least 2000, certain human activities and weather conditions during the winter months can cause spikes in air pollution. Wood burning, building heating, and car idling are the primary sources of this wintertime pollution.

Wood burning is a significant contributor to fine particle pollution, which can cause serious health issues such as cardiovascular and respiratory diseases and cancer. The combustion of wood produces heat, gases, and solid residues like ashes, dust, and fine particles that are dispersed through smoke. Older and less efficient wood-burning appliances, such as open fireplaces and old stoves, tend to produce more fine particles, exacerbating air pollution. Residential wood burning has been found to be a major source of particle pollution in various locations, including Portland, Oregon; Las Vegas; Atlanta, Georgia; Christchurch and Auckland in New Zealand; Melbourne; and Paris. In these places, wood burning can account for up to 79% of fine particulate pollution during the winter.

Building heating is another major source of wintertime pollution in Albuquerque. The increased demand for heat during colder months leads to a rise in energy usage, with many homes and businesses relying on fossil fuels for energy. This results in higher emissions of PM2.5 and other toxic air pollutants. While heating is necessary for comfort and health during cold weather, the type of heating system and fuel used can significantly impact air quality.

Car idling, particularly while warming up vehicles, also contributes to increased air pollution during the winter. Idling cars emit PM2.5 and other harmful pollutants, adding to the overall pollution levels in Albuquerque.

To mitigate the impact of these pollution sources, it is essential to consider alternative heating methods and promote the use of cleaner, more efficient technologies. Educating residents about the risks of fine particle pollution and encouraging the adoption of renewable and cleaner energy sources can help reduce emissions and improve air quality during the winter months in Albuquerque.

Travel-Demand Management strategies aim to reduce vehicle emissions and congestion

Albuquerque, New Mexico, has had a "good" annual mean Air Quality Index (AQI) since at least 2000. The AQI is calculated by weighing six major air pollutants for their threat to health: ozone (O3), PM2.5, PM10, carbon monoxide (CO), sulfur dioxide (SO2), and nitrogen dioxide (NO2). Despite this, short-term pollution spikes still pose health risks to residents. For example, in 2019, Albuquerque's ozone levels exceeded the federal allowance of 3.2 unhealthy ozone days. This is often due to the city's terrain, which is surrounded by mountains, creating a natural barrier that contributes to lighter winds and more stagnant air.

To address these air pollution challenges, Travel-Demand Management (TDM) strategies can be employed to reduce vehicle emissions and congestion. TDM aims to maximize the efficiency of transportation systems, reduce travel demand, and redistribute demand spatially and temporally. Here are some specific TDM strategies that can be implemented:

• Encourage ridesharing and alternative commuting options: This can be achieved through transportation management associations that leverage public and private funds. Ridesharing and alternative options like carpooling, public transportation, or active commuting (e.g., walking and cycling) can reduce the number of single-occupancy vehicles on the road, thereby lowering emissions and congestion.
• Improve pedestrian and active transportation infrastructure: This includes implementing pedestrian-oriented design elements such as short pedestrian crossings, wide sidewalks, and street trees. Such improvements encourage walking and make it safer and more accessible, reducing the reliance on private vehicles.
• Provide traveler information tools: Intelligent transportation system improvements, mobile applications, and wayfinding tools can promote alternatives to single-occupancy vehicle modes. For example, real-time traffic and pollution data can help individuals plan their travel to avoid congested or polluted areas.
• Implement congestion pricing and road space rationing: During peak hours, congestion pricing can be applied to charge road users based on when, where, and how much they drive. Additionally, alternate-day travel restrictions based on license plate numbers can be enforced to manage demand and reduce vehicle emissions.
• Flex-time work schedules: Encouraging flexible work schedules with employers can help reduce congestion during peak commuting times.
• Improve public transportation and active transportation options: Increasing the efficiency and accessibility of public transportation, as well as promoting active transportation options like walking and cycling, can reduce the reliance on private vehicles, thereby lowering emissions and congestion.

By implementing these TDM strategies, Albuquerque can aim to reduce vehicle emissions, mitigate congestion, and improve the overall air quality for its residents, creating a healthier and more sustainable urban environment.
