Fossil Fuels: Harmful Emissions Before Burning

Fossil fuels are formed from the decomposition of carbon-based organisms that died millions of years ago. They are the primary source of energy for human activities, powering transportation, industrial processes, and electricity generation. However, the extraction and burning of fossil fuels have severe environmental and health consequences. Even before combustion, fossil fuels emit harmful air pollutants. For instance, a 2017 study revealed that 17.6 million Americans are exposed daily to toxic air pollution from active oil and gas wells, transport, and processing facilities. This includes carcinogens such as benzene and formaldehyde. Furthermore, mining operations generate toxic airborne particulate matter, and fracking, a controversial extraction method, leads to air and water pollution. When fossil fuels are burned, they release greenhouse gases, nitrogen oxides, and airborne particles, contributing to global warming, smog, acid rain, and health issues.

Oil and gas wells, transport and processing facilities emit harmful air pollutants

Oil and gas wells, transport, and processing facilities emit harmful air pollutants, even before fossil fuels are burned. A 2017 study published in Environmental Health Perspectives revealed that approximately 17.6 million Americans are exposed daily to toxic air pollution from active oil and gas wells, as well as transport and processing facilities. These pollutants include benzene, which is linked to childhood leukaemia and blood disorders, and formaldehyde, a carcinogenic chemical.

The oil and gas industry emits various air contaminants throughout the development process, including during exploration, production, refining, processing, and combustion. Chief among these pollutants are methane (CH4), nitrogen oxide (NOx), sulfur dioxide (SO2), and high levels of volatile organic compounds (VOCs) that contribute to the formation of harmful ozone in the lower atmosphere. VOCs are released from vehicles and equipment used in oil operations and can also evaporate directly from oil and gas during extraction, storage, and transportation.

Flaring, the burning of excess natural gas at oil and gas wells, is a significant source of methane pollution, a potent greenhouse gas contributing to climate change. Oil spills, a common occurrence during fossil fuel extraction, transportation, and refining, can also lead to environmental disasters, harming communities, wildlife, and natural habitats.

The health impacts of these air pollutants disproportionately affect communities of colour and low-income communities. For example, in "Cancer Alley," a predominantly Black and low-income area of Louisiana, the cancer risk is nearly 50 times higher than the national average due to the high number of nearby chemical plants and oil refineries.

Overall, the oil and gas industry's air pollution contributes to global warming, climate change, and severe health issues, making the transition to clean energy an urgent necessity.

Fracking and mining operations generate toxic airborne particulate matter

Fossil fuels emit harmful air pollutants long before they are burned. According to a 2017 study, around 17.6 million Americans are exposed daily to toxic air pollution from active oil and gas wells, as well as transport and processing facilities. These include toxic chemicals like benzene and formaldehyde, which have been linked to serious health issues such as childhood leukaemia, blood disorders, and cancer.

Fracking, or hydraulic fracturing, is a controversial method of extracting oil and gas that contributes significantly to air pollution. The process involves injecting vast amounts of water, mixed with chemicals and sand, into a well at extremely high pressures. This fractures the rock and releases the oil or gas trapped within. The chemicals used in fracking, such as benzene, toluene, ethylbenzene, and xylene, are known to produce cancer-causing ultra-fine particles and aromatic hydrocarbons. These toxic chemicals not only pollute the air but also contaminate water sources, posing risks to both human health and the environment.

Mining operations, including those for fracking sand, also generate toxic airborne particulate matter. Surface mining involves removing vegetation, topsoil, and extracting the underlying sandstone containing silica sand. The subsequent processes of screening, washing, and drying the sandstone can generate airborne particulate matter, especially when the wind blows over storage piles. Miners are at high risk of exposure to toxic aerosols, including crystalline silica and diesel particulate matter. Inhalation of crystalline silica, for example, can lead to silicosis, an incurable and potentially fatal lung fibrosis.

Communities living near mining operations are also at risk of exposure to airborne particulate matter. While regulatory agencies, such as the United States Environmental Protection Agency (EPA), have set standards for particulate matter pollution, monitoring and controlling exposure to toxic substances in mining environments remains challenging. The dispersion modelling of a mine and processing facility indicated that particulate matter concentrations can exceed standards even at short distances beyond property lines.

The environmental and health impacts of fossil fuels disproportionately affect communities of colour and low-income communities. For instance, in "Cancer Alley," a predominantly Black and low-income area of Louisiana, the cancer risk is nearly 50 times higher than the national average due to the high concentration of chemical plants and oil refineries in the region.

Oil spills harm communities, wildlife, and the ocean's ecosystem

Fossil fuels emit harmful air pollutants long before they are burned. A 2017 study published in Environmental Health Perspectives found that 17.6 million Americans are exposed daily to toxic air pollution from active oil and gas wells, transport and processing facilities. These include benzene, which is linked to childhood leukaemia and blood disorders, and formaldehyde, a cancer-causing chemical.

Oil spills are a significant consequence of the extraction, transportation, and refining of fossil fuels, and they have devastating impacts on communities, wildlife, and ocean ecosystems. Oil spills can occur naturally, but most damaging spills are caused by anthropogenic factors such as leaks and spills during refining, handling, transport, storage, and use. Accidental spills can occur due to improper storage or accidents in offshore drilling, while there are also intentional discharges, such as tanker ship captains washing residue oil into the ocean.

The magnitude of harm caused by oil spills to wildlife varies depending on factors such as the extent of the spill, the length of time the oil is present, and the age and health of the affected animals. Oil spills can cause immediate health problems and long-term physiological and behavioural changes in marine and coastal wildlife. Skin irritation, immune system alterations, reproductive or developmental damage, and liver disease are common issues. Inhalation of volatile chemicals released by oil on the water surface can lead to respiratory inflammation, irritation, emphysema, or pneumonia in marine mammals like dolphins and whales that come to the surface to breathe. Oil ingestion can also directly poison wildlife, and even cause reproductive issues and death in fish and shellfish.

Oil spills also harm ocean ecosystems more broadly. They can destroy the insulating ability of fur-bearing mammals and the water-repelling abilities of birds' feathers, exposing them to harsh elements. Additionally, oil spills can lead to beach, park, and fishery closures, shoreline erosion, and habitat destruction.

Communities are also severely impacted by oil spills. The 2010 BP Deepwater Horizon spill in the Gulf of Mexico, the largest in history, killed 11 people and countless birds, turtles, fish, marine mammals, and plants. It also cost BP $65 billion in penalties and cleanup costs. Oil spills disproportionately affect communities of colour and low-income communities, with Black and Hispanic Americans exposed to significantly higher levels of pollution.

Burning fossil fuels releases nitrogen oxides, contributing to smog and acid rain

Burning fossil fuels has been the primary source of energy for over a century. However, it has detrimental effects on the environment and human health. Fossil fuels are non-renewable energy sources formed from the fossilized remains of plants and animals that lived millions of years ago. Oil, coal, and natural gas are examples of fossil fuels that, when burned, release carbon dioxide (CO2) and nitrous oxide (N2O) into the atmosphere. These gases are known as greenhouse gases, and they contribute to the greenhouse effect, leading to an increase in the Earth's average air temperatures.

Additionally, burning fossil fuels emits harmful air pollutants, including nitrogen oxides (NOx). Nitrogen oxides are one of the most common nitrogen-related compounds emitted into the air by human activities, particularly the burning of fossil fuels associated with transportation and industry. When released into the atmosphere, nitrogen oxides react with other chemicals to form smog and acid rain. Smog is a type of air pollution that reduces air quality and can have negative effects on human health, such as respiratory diseases.

Acid rain is formed when nitrogen oxides and other pollutants react with water vapor and oxygen in the atmosphere. Acid rain increases the acidity of precipitation, leading to contaminated freshwater sources. This contamination can result in harmful algal blooms that reduce water oxygen levels, harming fish populations and other aquatic life. Acid rain also contributes to the chemical weathering of rocks and man-made structures. The deposition of excess nitrogen in the form of nitrogen oxides or ammonia onto land can be washed into nearby water bodies, further contributing to water pollution.

The burning of fossil fuels has far-reaching consequences for the environment and human health. It is a significant contributor to climate change, altering the Earth's ecosystems and causing extreme weather events, sea level rise, and damage to crops and forests. Additionally, air pollution from fossil fuels can lead to respiratory issues and increase the risk of asthma, cancer, heart disease, and premature death. To mitigate these impacts, it is crucial to transition to cleaner energy sources and reduce our reliance on fossil fuels.

Air pollution from fossil fuels causes asthma, cancer, heart disease, and premature death

The burning of fossil fuels has been the primary source of energy for over a century. Fossil fuels include coal, oil, and natural gas, and they are used to generate electricity, power transportation, and drive industrial processes. However, the use of fossil fuels comes at a significant cost to human health and the environment.

Even before fossil fuels are burned, they emit harmful air pollutants. A 2017 study found that 17.6 million Americans are exposed daily to toxic air pollution from active oil and gas wells, transport, and processing facilities. These pollutants include benzene, which is linked to childhood leukemia and blood disorders, and formaldehyde, a known carcinogen. Mining operations also generate toxic airborne particulate matter.

When fossil fuels are burned, they release an array of pollutants that reduce air quality and harm human health. These pollutants include nitrogen oxides, sulfur dioxide, and airborne particles such as soot. Poor air quality caused by these pollutants is linked to respiratory diseases, including asthma. Additionally, the combustion of fossil fuels produces ultra-fine particles and aromatic hydrocarbons, which are known to cause cancer.

The health impacts of fossil fuel pollution disproportionately affect certain communities. For example, Black and Hispanic Americans are exposed to significantly higher levels of particulate matter pollution than the average population. In "Cancer Alley," a predominantly Black and low-income area of Louisiana, the cancer risk is nearly 50 times the national average due to the high number of nearby chemical plants and oil refineries. Children are also particularly vulnerable to the health effects of fossil fuel pollution, with studies showing links to preterm birth, low birth weight, and neurodevelopmental disorders.

Fossil fuel pollution has severe consequences for cardiovascular health as well. It is a significant contributor to heart disease and premature death. In the United States alone, 350,000 premature deaths in 2018 were attributed to fossil fuel-related pollution. Globally, one in five deaths is linked to fossil fuel pollution.

In conclusion, air pollution from fossil fuels has detrimental effects on human health, causing asthma, cancer, heart disease, and premature death. It is essential to recognize the disproportionate impact on marginalized communities and children and to take urgent action towards a cleaner and more sustainable energy future.
