Florida's Air Pollution: Causes And Concerns

Florida's air pollution issues are exacerbated by its powerful economy, large population, and high levels of tourism. The state's air quality is impacted by various factors, including transport, trade, and vehicle ownership. The American Lung Association's 2020 State of the Air report found that particle pollution levels in certain metropolitan areas were higher than in the previous year's report. This pollution consists of a mixture of solid particles and liquid droplets, including acids, organic chemicals, metals, and soil or dust particles. The size of these particles is directly linked to their potential for causing health issues, with smaller particles posing a greater threat.

Vehicle emissions and transport

Florida's position as the third most populous state in the US, combined with its appeal as a tourist destination, contributes to a high volume of road traffic. Vehicle ownership is increasing, and with it, the number of cars on the road, leading to higher emissions of pollutants such as carbon monoxide, nitrogen dioxide, and particulate matter. These emissions have severe health implications, especially for those with pre-existing heart and respiratory conditions, older adults, children, and pregnant women.

The state's economy, while robust, also faces challenges due to its reliance on industries that contribute to air pollution. Transport is one of the key sectors driving Florida's economy, but it also contributes to the state's air quality issues. The mass movement of people and goods across the state, particularly in the pre-COVID-19 era, has led to a depreciation in air quality. This is evident in cities like Riverview, which recorded a yearly PM2.5 average of 15.7 μg/m³, placing it in the 'moderate' pollution bracket.

To address these issues, individuals can play a role by reducing their fossil fuel consumption and opting for public transportation when possible. Additionally, local energy conservation programs can help lower emissions and mitigate the environmental and health impacts of vehicle emissions. The Environmental Protection Agency (EPA) has also proposed amendments to the Clean Air Act, aiming to reduce toxic air pollutants and protect communities living near major roadways and other pollution sources.

Furthermore, the retirement of old, dirty diesel engines has contributed to a decrease in year-round particle pollution levels in certain areas of Florida. This is a positive step towards improving air quality and reducing the health risks associated with vehicle emissions and transport in the state.

Construction and demolition sites

PM2.5, or fine particles, are those with a diameter of 2.5 micrometers or smaller. They are particularly concerning as they can penetrate deep into the lungs and even enter the bloodstream. Inhalation of these fine particles has been linked to various adverse health effects, including lung and heart problems such as decreased lung function, asthma, irregular heartbeat, and an increased risk of heart attack. Vulnerable populations, including individuals with pre-existing heart and respiratory conditions, older adults, children, infants, and pregnant women, are at an even higher risk of experiencing health issues due to exposure to fine particulate matter.

PM10, or coarse particles, refer to particles larger than 2.5 micrometers but less than or equal to 10 micrometers in diameter. While they are considered less harmful than PM2.5, they can still cause respiratory issues, particularly for sensitive groups. Exposure to coarse particles is primarily associated with the aggravation of respiratory conditions such as asthma and can affect individuals with heart or lung disease, older adults, and children.

Construction and demolition activities can generate significant amounts of both PM2.5 and PM10. The disturbance of soil and materials during demolition, excavation, and construction processes can create clouds of dust that contain a mixture of solid particles and liquid droplets. These particles can be made up of various components, including acids, organic chemicals, metals, soil, and allergens. In addition to air pollution, construction and demolition sites can also contribute to soil and water pollution by leaking dangerous materials, such as lead or mercury, into the surrounding soil or nearby bodies of water.

To mitigate the impact of construction and demolition sites on air quality, it is essential to implement dust control measures, such as wetting down surfaces, using enclosures, and employing proper waste management practices. By minimizing the release of particulate matter into the air, these measures can help reduce the potential health risks associated with air pollution from construction and demolition activities. Additionally, individuals can protect themselves by monitoring local air quality and limiting their exposure on days with poor air quality, as well as using air purifiers indoors to filter out particulate matter.

Forest fires

Florida's air pollution issues are exacerbated by its robust economy, which includes industries such as trade, transportation, tourism, and utility production. The state's large population, high tourism rate, and increasing vehicle ownership also contribute to its air pollution problems.

Prescribed burning, or the controlled use of fire for land management, is a common practice in Florida. While it offers environmental and ecological benefits, it can also negatively impact air quality. Smoke from prescribed burns can affect roadways, schools, hospitals, and airports, posing a serious safety risk. To mitigate these risks, Florida Certified Burners undergo training to minimize the impact of smoke on sensitive areas. Additionally, burn managers are advised to communicate their plans to law enforcement and fire departments in advance.

To manage and monitor air quality, Florida has implemented various systems, such as the Florida Air Quality Index (AQI) and the Florida Spatial Air Quality System (SAQS). These systems provide real-time and historical data on pollution levels, helping individuals make informed decisions to limit their exposure to air pollution.

Population and tourism

Florida is the third most populous state in the United States, with around 21 million inhabitants. The state also attracts large numbers of tourists, particularly to its cities. This mass movement of people focused on trade, transport, and tourism leads to a subsequent depreciation in air quality.

Florida's powerful economy, which is focused on industries such as trade, transport, and utility production, also contributes to the state's air pollution issues. The combination of a growing population, a thriving economy, and high levels of tourism puts Florida at risk of increased pollution levels.

The state's large population and tourism industry also result in a high number of vehicles on the roads, which contribute to air pollution. Vehicle emissions, particularly from diesel fuel, release fine particulate matter and chemical pollutants into the atmosphere, negatively impacting air quality.

Additionally, the construction and maintenance of infrastructure to support Florida's growing population and tourism industry can contribute to air pollution. Construction sites, mining areas, road repairs, and demolition sites can release coarse particles, finely ground dust (PM2.5 and PM10), and dangerous materials such as lead or mercury into the air.

While Florida's population and tourism industry contribute to air pollution, the state has taken steps to monitor and improve air quality. The Florida Department of Environmental Protection provides up-to-date pollution data to the public through the Florida Air Quality System (FLAQS). This system operates a state-wide ambient air monitoring network, recording data 24 hours a day.

Coal-fired power plants and factories

Florida's strong economy, robust infrastructure, and diverse sector industries make it an attractive destination for manufacturers. The state is home to 12,004 manufacturing companies, with hubs in Miami-Dade, Orange, and Pinellas counties. These companies produce fabricated metal products, electronics, food, industrial machinery, and printing and publishing.

Florida's economy is also focused on trade, transport, and utility production. The state's large population of around 21 million, high tourism, and increasing vehicle ownership also contribute to air pollution.

In July 2007, Florida's newly elected Republican governor, Charlie Crist, signed an executive order mandating that CO2 emissions be reduced to 40% below 2007 levels by 2025. This has made it nearly impossible to build another traditional coal-fired power plant, and several proposals have since been canceled or rejected. This decision was made following discussions with state officials and the hope to reduce emissions to 1990 levels.

The scheduled closure of the two Crystal River coal plants, which opened in 1966 and 1969, will help the state achieve this goal. The energy from these plants will be replaced by a new nuclear plant in Levy County. However, two coal-fired power generators will remain in operation at the Citrus County site, along with a nuclear reactor.

According to a 2011 NRDC report, Florida, along with Ohio and Pennsylvania, has the most toxic air pollution from coal- and oil-fired power plants. In 2009, Florida released nearly 50 million pounds of toxic air pollutants, with 33.4 million pounds coming from the electricity sector. The same report listed the two Crystal River coal plants among the nation's top 50 polluters.
