Coal contributes to air pollution, causing asthma, respiratory illnesses, and heart disease
Coal is a significant contributor to air pollution, which has been linked to a range of respiratory illnesses, including asthma, bronchitis, and other lung conditions. Air pollution from coal-fired power plants can cause serious health issues, particularly for those living in close proximity to these plants.
Coal-fired power plants emit toxic pollutants, including soot, which is composed of small particles of metals, chemicals, and acid droplets. These particles are easily inhaled and can reach deep into the lungs, causing damage and leading to respiratory illnesses. Children are especially vulnerable, with studies showing a higher prevalence of asthma and respiratory symptoms in children living near opencast coal mining sites.
Coal mining and the burning of coal release harmful substances such as mercury, sulfur dioxide, nitrogen oxides, and particulate matter. These emissions contribute to smog, haze, and poor air quality, which have been linked to respiratory ailments and lung diseases. Sulfur dioxide, for instance, contributes to acid rain, which has further environmental and health impacts.
In addition to respiratory illnesses, air pollution from coal has been associated with heart conditions. Toxic pollutants can lead to heart attacks, arrhythmias, and congestive heart failure. Furthermore, coal dust inhalation can result in coal worker's pneumoconiosis, commonly known as "black lung disease," which causes scarring and inflammation in the lungs, impairing respiratory function over time.
The pollution from coal-fired power plants and coal mining has far-reaching consequences for human health and the environment. It is crucial to address these issues and transition to cleaner energy sources to protect the health and well-being of communities, especially those living near coal-burning power plants and coal mines.

These emissions contain hazardous substances such as coal micro-particles, nanoparticles, and heavy metals, which, when inhaled, pose serious health risks.
The burning of coal releases several principal emissions, including mercury, a heavy metal that has been linked to neurological and developmental damage. Other emissions include sulfur dioxide, nitrogen oxides, particulates, and carbon dioxide. These emissions contribute to respiratory illnesses, smog, haze, lung disease, and global warming.
The continuous inhalation of these hazardous substances has been linked to triggering diseases such as respiratory and cardiovascular disease, systemic inflammation, and neurodegeneration. The health impacts of coal pollution can range from asthma and breathing difficulties to brain damage, heart problems, cancer, neurological disorders, and premature death.
The release of toxic substances from coal has severe effects on the health of miners, workers, and surrounding communities. In Australia, coal's health impacts have resulted in higher rates of childhood asthma, heart and lung disease, and certain cancers, costing taxpayers an estimated $2.4 billion annually. Similarly, in China and India, coal-related deaths have reached staggering numbers, with 366,000 and 169,000 deaths attributed to coal annually in these countries, respectively.
The environmental and health impacts of coal pollution highlight the importance of transitioning to cleaner sources of electricity and implementing measures to reduce emissions and safeguard human health.

Coal-fired power plants emit fine particulate matter (PM2.5), increasing the risk of premature death
Coal is a carbon-rich black rock formed deep underground over thousands of years. When burned, it releases energy and reacts with oxygen in the air to produce carbon dioxide, a greenhouse gas. Coal is the most polluting way to produce electricity, releasing massive amounts of pollution and severely affecting the health of miners, workers, and surrounding communities.
Coal-fired power plants emit fine particulate matter (PM2.5) into the air, which is associated with an increased risk of premature death. A study by George Mason University, the University of Texas at Austin, and Harvard T.H. Chan School of Public Health found that exposure to PM2.5 from coal-fired power plants is more than twice as deadly as exposure to PM2.5 from other sources. The study analyzed Medicare and emissions data in the U.S. from 1999 to 2020 and found that 460,000 deaths were attributable to coal PM2.5 during this period, with most occurring between 1999 and 2007 when coal PM2.5 levels were highest.
Coal PM2.5 is rich in sulfur dioxide, black carbon, and metals, making it more harmful than previously thought. The researchers calculated that for every 1 μg/m3 increase in coal PM2.5, mortality increased by 1.12%, a risk 2.1 times greater than that of PM2.5 from any other source. This risk is likely due to the high toxicity of coal PM2.5 compared to other sources of PM2.5.
The good news is that deaths from coal PM2.5 have decreased significantly over time due to coal power plant retirements and air pollution regulations that have reduced emissions. From 2000 to 2008, deaths associated with coal PM2.5 were 25% of all PM2.5-related deaths, but this declined to 7% from 2013 to 2016. By 2020, coal PM2.5 levels had decreased by about 95% as coal plants installed scrubbers or shut down. This highlights the success of emissions reduction policies in improving health outcomes.
Overall, coal-fired power plants' emission of fine particulate matter (PM2.5) poses a serious risk to human health, contributing to premature death. The transition away from coal towards cleaner sources of electricity is essential for reducing these health impacts and improving air quality.
