Air Pollution's Impact On Ohio: A Health Hazard

Ohio is the seventh most populous state in the US, with over 11.7 million inhabitants. The state has a strong industrial presence, with large amounts of manufacturing and automobile production. This, coupled with its dense population, means that Ohio is subject to air pollution issues. The state's cities have recorded varying levels of PM2.5—a particulate matter with a diameter of 2.5 micrometres or less that is extremely harmful to human health when inhaled. Certain cities in Ohio, such as Cleveland and Seville, have recorded relatively high PM2.5 readings, indicating poor air quality.

The main causes of air pollution in Ohio are vehicle emissions, industrial activities, forest fires, and power plants. These sources release pollutants such as nitrogen dioxide, sulfur dioxide, black carbon, and volatile organic compounds. The effects of air pollution on human health are varied and depend on factors such as length of exposure and individual health history. However, some common health issues associated with air pollution include respiratory and cardiovascular problems, such as coughing, chest pain, asthma, and increased risk of infection.

Air pollution in Ohio: health problems

Air pollution in Ohio is a pressing issue that poses risks to human health and can have adverse effects on the well-being of its residents. The state's dense population, coupled with its significant industrial presence and vehicle emissions, contributes to elevated levels of air pollution. The high levels of particulate matter, ground-level ozone, and other pollutants in the air have been linked to a range of health concerns.

One of the most common health issues associated with air pollution in Ohio is respiratory problems. The fine particulate matter in the air, such as PM2.5, can reach deep into the lungs and even enter the bloodstream. This can lead to coughing, wheezing, throat irritation, and increased risk of respiratory infections. Prolonged exposure to air pollution can also cause more severe respiratory conditions, including asthma, bronchitis, emphysema, and aggravated forms of asthma. The elderly, young children, pregnant women, and individuals with pre-existing health conditions are at a higher risk of experiencing these respiratory issues.

In addition to respiratory problems, air pollution in Ohio has been linked to cardiovascular risks. The inhalation of toxic chemicals and particulate matter can contribute to heart attacks, strokes, and congestive heart failure. It can also reduce the blood supply to the heart, leading to further complications.

Certain pollutants in the air, such as ground-level ozone and particulate matter, are known to increase the risk of lung cancer. The carcinogenic nature of these pollutants poses a serious health threat to Ohio residents, particularly those who are frequently exposed to high pollution levels.

Furthermore, air pollution has been associated with adverse effects on skin health. Irritation, rashes, and even skin cancer are possible consequences of exposure to air pollutants. Conditions such as atopic dermatitis and eczema may also be triggered or exacerbated by air pollution.

Compromised lung function is another concern, as lung tissue damage caused by air pollution can lead to a reduction in full lung capacity. This not only reduces the quality of life but also makes individuals more susceptible to respiratory conditions in the future.

It is worth noting that air pollution can also have systemic effects on the body, increasing the risk of premature birth, raising the risk of autism, and stunting lung development in children.

The health problems associated with air pollution in Ohio highlight the importance of taking measures to improve air quality and protect vulnerable individuals. While Ohio has made strides in addressing air pollution, there is still work to be done to ensure the health and well-being of its residents.

Causes of air pollution in Ohio

Ohio's air pollution issues are caused by a combination of factors, including vehicle emissions, industrial activities, and natural sources such as forest fires. The state's dense population and high level of industrial activity contribute to the problem.

Vehicle emissions are a significant contributor to air pollution in Ohio. With millions of residents, there are bound to be extensive commutes between cities, particularly towards major economic hubs. These daily vehicle movements release large amounts of exhaust fumes, which contain various chemical compounds and hazardous fine particulate matter. In addition to personal vehicles, heavy-duty trucks and lorries used for transporting industrial goods also contribute to air pollution, often running on diesel fuel and emitting greater amounts of pollutants than smaller vehicles. The wearing down of tires from excessive vehicle use also releases tons of microscopic rubber particles into the air and onto the ground.

Industrial activities, such as manufacturing and automobile production, also play a role in Ohio's air pollution. Emissions from power plants, factories, and industrial boilers release pollutants like nitrogen dioxide (NO2) and sulfur dioxide (SO2). Nitrogen dioxide, in particular, is highly correlated with traffic volume, indicating that industrial emissions and vehicle emissions often work together to negatively impact air quality.

Additionally, forest fires can cause massive clouds of smoke and haze to drift across cities, affecting air quality hundreds of miles away. While these natural occurrences are not unique to Ohio, they still contribute to the state's air pollution issues, especially when combined with other sources.

Other sources of air pollution in Ohio include construction sites, road repairs, dust storms, and the extraction of raw materials. Any activity that disturbs large portions of the earth's surface can release fine particulate matter into the air, posing risks to respiratory health.

Air pollution and climate change

The main cause of CO2 emissions is the extraction and burning of fossil fuels, which is also a major source of air pollutants. Air pollution, in the form of particulate matter, can circulate around the globe, ending up in remote places like the polar regions. When particulate matter lands on ice and snow, it darkens them, preventing sunlight from reflecting back into space, and contributing to global warming.

Short-lived climate-forcing pollutants (SLCPs) include methane, black carbon, ground-level ozone, and sulfate aerosols. These have significant impacts on the climate, with black carbon and methane being among the top contributors to global warming after CO2. Black carbon is a component of fine particulate matter (PM2.5), which is the air pollutant most harmful to human health and the primary driver of air-pollutant-induced mortality. Methane does not directly impact human health, but it is a precursor to ground-level ozone, which causes asthma and other respiratory diseases, and contributes to air pollution-related premature deaths.

To reach the Paris Agreement goal of limiting warming to 1.5 to 2 degrees Celsius, a rapid reduction of CO2 emissions is necessary, but not sufficient. Deep reductions in emissions of non-CO2 climate forcers, especially the air pollutants methane and black carbon, are also crucial. Acting on both fronts together presents an opportunity to improve lives now and limit future climate warming.

Ohio, the seventh most populous state in the US, has air pollution issues due to its large and dense population and high level of industrial activity. Its major city, Cleveland, had a PM2.5 reading of 12.4 μg/m³ as its yearly average, indicating pollution issues. PM2.5 refers to particulate matter that is 2.5 micrometres or less in diameter and is extremely harmful to human health. High levels of air pollution in Ohio can be attributed to vehicle emissions, heavy-duty vehicle use, forest fires, power plants, factories, construction sites, and road repairs. These sources release harmful pollutants such as nitrogen dioxide, sulfur dioxide, black carbon, volatile organic compounds (VOCs), methane, carbon monoxide, and ozone.

The adverse health effects of air pollution in Ohio include dry coughs, chest pains, mucous membrane irritation, skin irritation, and increased risk of lung cancer and respiratory conditions. Vulnerable groups such as young children, the elderly, pregnant women, and those with pre-existing health conditions are at an elevated risk of experiencing these health issues.

Ohio's air quality is impacted by its large population and significant industrial and manufacturing activity. The state's major cities, such as Cleveland, Seville, and Warrensville Heights, tend to have higher levels of air pollution, particularly from vehicle emissions and industrial sources.

Cleveland, for instance, recorded a PM2.5 reading of 12.4 μg/m³ as its yearly average in 2020, which placed it first in terms of pollution levels among Ohio's cities. Seville followed closely behind with a reading of 11.2 μg/m³, which also placed it 2085th worldwide. These readings indicate that there is room for improvement in Ohio's air quality, particularly in its larger cities.

Vehicle emissions are a significant contributor to air pollution in Ohio. The state's large population results in widespread commutes and daily mass movements of people in personal vehicles, releasing exhaust fumes and hazardous particulate matter into the air. In addition, the presence of heavy-duty vehicles used for transportation in the manufacturing and industrial sectors further exacerbates this problem.

Industrial activities, such as manufacturing and power generation, also play a role in Ohio's air pollution. Power plants, factories, and construction sites emit pollutants like nitrogen dioxide, sulfur dioxide, black carbon, and volatile organic compounds (VOCs). These emissions, coupled with those from vehicles, contribute to the state's overall air quality issues.

The effects of air pollution on health are significant. Inhaling polluted air can cause dry coughs, chest pains, mucous membrane irritation, skin issues, and heightened risks of lung cancer. It can also damage lung tissue, reducing lung function and making individuals more susceptible to respiratory conditions. Therefore, it is crucial for vulnerable groups, such as children, the elderly, pregnant women, and those with pre-existing health conditions, to take extra precautions during periods of high pollution.
