PM2.5 is the main pollutant

Sun City, AZ, currently has a "good" air quality rating, and air pollution poses little to no risk. However, PM2.5 is a serious pollutant that affects Arizona and can cause issues even in small quantities.

PM2.5 refers to particulate matter that is 2.5 micrometres or less in diameter, sometimes going down to far smaller sizes. Due to their microscopic size, these particles can be inhaled and cause serious health issues. They can enter the circulatory system and even the brain. Short-term exposure to PM2.5 has been linked to premature mortality, increased hospital admissions for heart or lung issues, acute and chronic bronchitis, asthma attacks, and restricted activity days, especially in infants, children, and older adults with pre-existing heart or lung diseases. Long-term exposure has been associated with reduced lung function growth in children and premature death in people with chronic heart or lung diseases.

PM2.5 particles are often emitted from the combustion of gasoline, oil, diesel fuel, or wood, as well as industrial processes and motor vehicle exhaust. They can also be formed through chemical reactions of gases like sulfur dioxide and nitrogen oxides. These particles can remain suspended in the air for extended periods and travel long distances through strong winds, affecting areas far from their source.

In 2020, Arizona had varying PM2.5 readings across its cities. Stanfield, for example, had a yearly average PM2.5 reading of 14.4 μg/m³, placing it in the "moderate" air pollution bracket. This reading was relatively high for a US city, indicating pollution-related problems. While Sun City currently has satisfactory air quality, the presence of PM2.5 in Arizona highlights the need for continued efforts to maintain and improve air quality.

Vehicular fumes and emissions are a source of air pollution

Sun City, AZ, currently has a good air quality rating, with little to no risk posed by air pollution. However, Arizona is a state with a diverse economy, including sectors such as transportation, healthcare, higher education, manufacturing, and construction, which can contribute to higher levels of pollution. Vehicular fumes and emissions are a significant source of air pollution, and certain areas of the state experience more significant pollution-related problems than others.

Vehicular emissions are a major source of air pollution, and motor vehicles remain a primary contributor to air pollutants, particularly in areas with more traffic. Cars, trucks, buses, off-road vehicles, and planes release pollutants directly into the atmosphere and are considered mobile sources of air pollution. The burning of fuel in internal combustion engines releases carbon monoxide, nitrogen oxides, and hydrocarbons. These emissions can cause smog and have adverse effects on human health, including damage to lung tissue and the exacerbation of respiratory diseases such as asthma.

Additionally, gasoline vapors can escape into the atmosphere during refueling and when fuel vaporizes from engines and fuel systems due to vehicle operation or hot weather. Diesel engines, while efficient, consume diesel fuel, a complex mix of petroleum components, and produce pollutants as well. A small portion of the fuel exits the engine unburned, and these airborne hydrocarbons can combine with dust and other particles to form larger pollutants in the atmosphere.

Furthermore, on warm, sunny days, hydrocarbons can react with oxides of nitrogen to create ground-level ozone, a common component of smog that irritates the respiratory system. Transportation is the largest source of heat-trapping emissions in the United States, and tailpipe emissions from cars, trucks, and buses account for a significant portion of the country's global warming pollution. These emissions contribute to climate change and have detrimental effects on human health, with exposure disproportionately impacting marginalized communities, including Latinos, Blacks, and lower-income households.

To address vehicular emissions and reduce air pollution, various measures have been implemented. These include supporting the development and sale of zero and low-emission vehicles, promoting clean vehicle and fuel technologies, and implementing emission control programs and inspection and maintenance protocols for vehicles.

Manufacturing and construction industries cause poorer air quality

Sun City, AZ, currently has a good air quality rating, with little to no risk to health. However, Arizona's economy is largely focused on sectors such as manufacturing and construction, which can cause poorer air quality. The state's diverse economy, which includes mining and exporting goods, can lead to increased pollution levels.

The manufacturing industry, for example, involves the production, processing, and extraction of raw materials, which results in harmful waste and emissions. This includes airborne pollutants such as PM2.5, sulfur dioxide, nitrogen oxides, and carbon monoxide, which are released by facilities like factories, power plants, and petrochemical plants.

The construction industry has also increased its share of emissions in recent decades, with less strict air quality regulations compared to other sectors. Construction and demolition activities produce large amounts of dust, containing particulate matter and volatile organic compounds, which can spread through the wind, affecting the surrounding areas. This dust, combined with gases from machinery, forms a toxic mixture that impacts the health of residents and passers-by.

Furthermore, the use of heavy machinery and diesel-fuelled vehicles on construction sites contributes to air pollution by releasing pollutants such as carbon monoxide and nitrogen oxides. These emissions can reduce visibility and even lead to accidents on roads and intersections.

To mitigate these issues, construction companies can adopt integrated approaches, combining technologies and best practices. Watering and misting systems, for instance, can significantly reduce airborne particulate matter, improving air quality for nearby communities. By implementing such strategies and adhering to regulations, the negative impacts of manufacturing and construction industries on air quality can be minimised.
