Fossil Fuels: Air Pollution's Primary Culprit

Burning fossil fuels releases large amounts of carbon dioxide, a greenhouse gas, into the air. This contributes to climate change, which has a range of impacts on human health, including respiratory disorders, heart disease, and premature death. Fossil fuels also produce hazardous air pollutants, including sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury, which can cause acid rain, eutrophication, damage to crops and forests, and harm to wildlife. In addition, the combustion of fossil fuels has been linked to an increased risk of asthma, cancer, autism spectrum disorder, and Alzheimer's disease. Overall, fossil fuel pollution is responsible for a significant number of deaths worldwide, with recent research suggesting that it may be responsible for as many as one in five deaths globally.

Fossil fuel combustion releases hazardous air pollutants, including nitrogen oxides and sulphur dioxide

Nitrogen oxides are released into the atmosphere when fossil fuels are burned, contributing to the formation of smog and acid rain. They are one of the most common nitrogen-related compounds emitted by human activities, including the burning of fossil fuels for electricity generation, industry, transportation, and agriculture. Major sources of nitrogen oxide emissions include coal-fired power plants and large industrial operations.

Nitrogen oxides can have detrimental effects on both human health and the environment. In humans, exposure to nitrogen oxides can cause respiratory problems, such as asthma and other chronic respiratory illnesses. They can also contribute to the development of heart disease and increase the risk of premature death. In the environment, nitrogen oxides can lead to acid rain, which can damage crops, forests, and aquatic ecosystems.

Sulphur dioxide is another hazardous air pollutant released during fossil fuel combustion. It is a major contributor to air pollution and has significant impacts on human health. When inhaled, sulphur dioxide can irritate the respiratory system, exacerbating respiratory conditions such as asthma and chronic bronchitis. Prolonged exposure to high levels of sulphur dioxide can lead to respiratory tract infections, aggravate existing heart disease, and increase the risk of premature death.

Additionally, sulphur dioxide emissions contribute to the formation of fine particulate matter, known as PM2.5. These tiny particles can be inhaled and penetrate deep into the lungs, causing serious health issues. Exposure to PM2.5 has been linked to an increased risk of cardiovascular disease, cancer, tissue damage, and respiratory ailments. Vulnerable populations, such as young children and individuals with pre-existing health conditions, are particularly susceptible to the harmful effects of PM2.5.

The combustion of fossil fuels, including coal, oil, gasoline, diesel, and natural gas, is a major source of air pollution and greenhouse gas emissions. It is estimated that fossil fuel combustion is responsible for the majority of air pollution globally, with significant impacts on human health and the environment. Reducing the use of fossil fuels and transitioning to cleaner energy sources is crucial to mitigating these impacts and improving air quality.

Fossil fuel emissions are the dominant cause of global warming

Coal is a fossil fuel and is the dirtiest of them all, responsible for over 0.3C of the 1C increase in global average temperatures. This makes it the single largest source of global temperature rise. Oil releases a huge amount of carbon when burned - approximately a third of the world's total carbon emissions. Natural gas is often promoted as a cleaner energy source than coal and oil, but it is still a fossil fuel and accounts for a fifth of the world's total carbon emissions.

Burning fossil fuels produces hazardous air pollutants, including sulfur dioxide, nitrogen oxides, particulate matter, carbon monoxide, and mercury, all of which are harmful to the environment and human health. Fossil fuel emissions can cause multiple health issues, including asthma, cancer, heart disease, and premature death. Globally, fossil fuel pollution is responsible for one in five deaths. In the United States, 350,000 premature deaths in 2018 were attributed to fossil fuel-related pollution. The annual cost of the health impacts of fossil fuel-generated electricity in the United States is estimated to be up to $886.5 billion.

The environmental and health impacts of fossil fuels disproportionately harm communities of color and low-income communities. Black and Hispanic Americans are exposed to 56% and 63% more particulate matter pollution, respectively, than they produce. Fossil fuel emissions are also a major contributor to ocean acidification, extreme weather, and sea level rise.

Fossil fuel pollution is responsible for one in five deaths worldwide

The study, "Global Mortality From Outdoor Fine Particle Pollution Generated by Fossil Fuel Combustion", was based on an analysis that enabled researchers to directly attribute premature deaths from fine particulate pollution (PM 2.5) to fossil fuel combustion. PM 2.5 includes any airborne particle that is up to 2.5 microns in diameter, which is about one-thirtieth the width of a single human hair. These particles are problematic because they linger in the air, are readily inhaled, and can penetrate deep into the lungs, where they can enter the bloodstream and inflict damage on multiple organs.

The findings of the study underscore the detrimental impact of fossil fuels on global health. Transitioning from fossil fuels to renewable energy sources has immediate health benefits, including preventing premature deaths attributed to fossil fuel pollution. Exposure to particulate matter from fossil fuels accounted for 21.5% of total deaths in 2012, falling to 18% in 2018 due to tightening air quality measures in China.

In addition to the health impacts, the use of fossil fuels also results in significant climate, environmental, and economic costs. For example, in the United States, the annual cost of the health impacts of fossil fuel-generated electricity is estimated to be up to $886.5 billion. Furthermore, the environmental and health impacts of fossil fuels disproportionately harm communities of color and low-income communities.

Overall, the study sends a clear message to policymakers and stakeholders about the benefits of transitioning to alternative energy sources. By reducing our dependence on fossil fuels, we can not only mitigate climate change but also significantly improve global health and reduce the number of premature deaths caused by air pollution.

Fossil fuel combustion releases ultra-fine particles and aromatic hydrocarbons, which cause cancer

Fossil fuel combustion releases ultra-fine particles and aromatic hydrocarbons, which have been linked to cancer. These pollutants are released into the atmosphere when fossil fuels such as coal

Fossil fuel combustion releases carbon monoxide, which is harmful to human health

The most common effects of CO exposure are fatigue, headaches, confusion, and dizziness due to inadequate oxygen delivery to the brain. For people with cardiovascular disease, short-term CO exposure can further reduce their body's already compromised ability to respond to the increased oxygen demands of exercise, exertion, or stress. Inadequate oxygen delivery to the heart muscle leads to chest pain and decreased exercise tolerance. Unborn babies whose mothers experience high levels of CO exposure during pregnancy are at risk of adverse developmental effects.

Carbon monoxide can be released by a wide variety of combustion sources, including motor vehicles, power plants, wildfires, and incinerators. In urban areas, the majority of outdoor CO emissions come from mobile sources. CO can also be formed through photochemical reactions in the atmosphere from methane and non-methane hydrocarbons, other volatile organic hydrocarbons, and organic molecules in surface waters and soils. There are also a number of indoor sources of CO, such as gas stoves, malfunctioning or improperly vented gas appliances, space heaters, fireplaces, tobacco smoke, and car or truck exhaust from attached garages.

In the United States, over 400 people die each year from CO poisoning, with 13 to 36 of these deaths occurring in California since 2000 from non-fire-related CO poisoning. Due to the health risks associated with CO poisoning, California has mandated the installation of CO detectors in all housing units in the state.
