Industries' Dark Side: Air Pollution And Health Hazards

Industrial air pollution is a pressing issue that affects the health and well-being of individuals and the environment. Industrial processes and activities generate emissions of hazardous substances, such as nitrogen oxide, ammonia, mercury, and carbon dioxide, which are released into the air. These pollutants can cause respiratory and cardiovascular diseases, decreased lung function, and asthma, with long-term exposure leading to more severe health issues. Industries such as natural gas, plastic, chemical, electric generation, and waste disposal are major contributors to air pollution, impacting communities near industrial townships and beyond.

Industrial activities emit hazardous substances like nitrogen oxide, ammonia, mercury and carbon dioxide

Industrial activities are a major contributor to air pollution, emitting a range of hazardous substances into the atmosphere. Among these are nitrogen oxide, ammonia, mercury, and carbon dioxide. These pollutants have far-reaching impacts on both human health and the environment.

Nitrogen oxide (NOx) is a significant atmospheric pollutant, with industrial processes being a leading source. NOx is formed during combustion processes, particularly at high temperatures, and through the reaction of nitrogen and oxygen in combustion air. The semiconductor, power plant, and agriculture industries are notable contributors to NOx emissions. Governments worldwide are implementing stricter regulations to curb NOx emissions, recognising their detrimental impact on air quality.

Ammonia (NH3) production, particularly through the energy-intensive Haber-Bosch process, is another source of industrial air pollution. This process, responsible for producing ammonia-based fertilisers, results in substantial carbon dioxide (CO2) emissions. With agriculture relying heavily on these fertilisers, the indirect CO2 emissions from industrial ammonia production are significant. Scientists are actively seeking ways to reduce the greenhouse gas emissions associated with ammonia production.

Mercury emissions from industrial processes also contribute to global air pollution. Mercury released into the atmosphere through activities such as mining and fossil fuel combustion can travel long distances before settling back to Earth. This toxic substance poses risks to human health, particularly during fetal development and early childhood. Additionally, mercury deposited into water bodies can be transformed into methylmercury, which accumulates in fish and shellfish, leading to health issues for consumers.

Carbon dioxide (CO2) emissions from industrial activities, including electricity and heat production, manufacturing, and construction, significantly contribute to global greenhouse gas emissions. While efforts are being made to reduce emissions, industrial activities continue to play a major role in climate change and air pollution.

Industrial air pollution can cause respiratory and cardiovascular diseases, cancers, and asthma

Industrial emissions are a major cause of air pollution, with large industrial plants emitting pollutants into the air, water, and land. These emissions contain harmful substances, including fine particulate matter (PM2.5), gases, and chemicals, which have detrimental effects on human health. PM2.5, in particular, consists of tiny particles that can penetrate deep into the lungs and even enter the bloodstream, causing irritation and damage.

The health impacts of industrial air pollution are significant and wide-ranging. One of the most concerning consequences is the development or exacerbation of respiratory diseases, including asthma. When individuals inhale polluted air, small particles and irritating gases can irritate the airways and lungs, triggering asthma symptoms and increasing the frequency of hospital visits. Vulnerable groups, such as people with pre-existing asthma, are particularly susceptible to the harmful effects of air pollution.

In addition to respiratory issues, industrial air pollution contributes to the development of cardiovascular diseases. Studies have shown that exposure to PM2.5, even over a short period of a few hours to weeks, can trigger cardiovascular events such as heart attacks and death. Long-term exposure further increases the risk of cardiovascular mortality and decreases life expectancy. Individuals with underlying cardiovascular conditions or traditional risk factors, such as high blood pressure or smoking, are at an even higher risk of adverse health outcomes.

Furthermore, air pollution has been linked to an increased risk of cancer, particularly lung cancer. While reducing air pollution directly mitigates the risk of lung cancer, it also encourages healthier habits, such as increased physical activity and improved diet, which can reduce the likelihood of developing other types of cancer. Additionally, air pollution can interfere with cancer treatments, reducing the effectiveness of chemotherapy drugs and potentially causing surgical complications.

The impact of industrial air pollution on human health is a pressing issue, with nearly seven million deaths attributed to it annually. Addressing and mitigating industrial air pollution is crucial to reducing its harmful health effects and improving the quality of life for people worldwide.

Industries such as natural gas, plastic, chemical, electric generation, and waste disposal generate hazardous waste

Natural gas is a relatively clean-burning source of energy, producing fewer emissions of nearly all types of air pollutants and carbon dioxide (CO2) compared to coal or petroleum products. However, natural gas production and transportation can still cause air pollution. For instance, during well drilling, natural gas can be released into the atmosphere, and the engines used to run equipment and compressors at natural gas wells produce air pollutants and noise. Additionally, natural gas produced at some oil wells is burned at well sites, producing CO2, carbon monoxide, sulfur dioxide, nitrogen oxides, and other compounds, depending on the gas's chemical composition and how well it burns.

The plastic industry is also a significant contributor to air pollution. Plastics are primarily made from fossil fuels, and the extraction and refinement processes release toxic emissions. Oil and gas drilling release contaminants like benzene, carbon monoxide, hydrogen sulfide, and volatile organic compounds. Recycling plastic can also contribute to air pollution when it is incinerated or when unsafe working conditions and a lack of pollution control measures are present.

The chemical industry emits a wide range of harmful substances that negatively affect the environment and human health. These emissions can include halogens, organic solvents, smoke, dust, and odours.

Electric power plants burning fossil fuels or materials made from fossil fuels contribute to air pollution. In 2022, they were the source of about 31% of total US energy-related CO2 emissions. Power plants burning solid fuels like coal produce ash, which contains hazardous materials captured by pollution control devices. The ash is often stored in retention ponds that pose risks to groundwater if left unlined.

Lastly, the waste disposal industry contributes significantly to air pollution. Open dumping and burning of waste release harmful substances into the air, impacting human health and the environment. Informal waste workers are often hired to work in unsafe conditions without proper protective gear, exposing them to harmful chemicals released during waste disposal.

Overall, these industries' activities generate hazardous waste and air pollutants, underscoring the need for improved waste management practices, stricter regulations, and the development of cleaner energy sources to mitigate their environmental and health impacts.

Oil and gas operations, from production to distribution, release air pollution that negatively affects public health

The toxic nature of the hundreds of chemicals and pollutants associated with oil and gas development is well-established. The most common symptoms experienced by residents of oil and gas field communities include respiratory problems like asthma and coughing, eye, nose, and throat irritation, headaches, nausea, dizziness, trouble sleeping, and fatigue. These symptoms can start or worsen after oil and gas development activities begin in an area.

In addition, the creation and storage of waste, the constant noise, and the light that exists around operations can also impact health. For example, noise and odor are the most common complaints from people living near oil and gas activity. Furthermore, leaks, flames, and excessive emissions from refineries release dangerous air pollutants or toxicants known or suspected to cause cancer and congenital disabilities.

The health impacts of oil and gas pollution are not limited to populations living near extraction sites. Research has shown that pollution from oil and gas production can travel long distances, affecting populations far from the production sites. The five states with the highest impacts from oil and gas pollution in the United States are Texas, Pennsylvania, Ohio, Oklahoma, and Louisiana. However, Illinois and New York, which produce very little oil and gas, still ranked 6th and 8th in terms of health impacts. This indicates a need for regional to nationwide coordination to address the issue.

Industrial townships are designed to support the needs of the industries, including access to transportation networks and energy resources

Industrial townships are designed to support the needs of the industries they house, including access to transportation networks and energy resources. These townships are designated areas set aside for industrial activities and businesses, typically developed by governments or private organisations. They aim to attract investment and promote economic development by providing a comprehensive range of facilities and services.

The process of acquiring land for an industrial township involves identifying suitable land, negotiating with landowners, and obtaining government approvals. The land should be appropriate for the specific industries, with proper connectivity to transportation networks, nearby sources of raw materials and labour, and other supporting facilities. The Indian government, for example, has been promoting the development of industrial townships to boost economic growth and create jobs.

Industrial townships may include various facilities such as power plants, water treatment plants, and waste management facilities. They also provide transportation infrastructure like ports, airports, and road and rail networks. These townships may offer incentives such as tax breaks, subsidies, and streamlined regulatory processes to attract industries further. Some even provide training programs for workers and R&D support for industries.

The presence of these townships supports industries by providing them with the necessary infrastructure and resources to operate and grow. They facilitate efficient transportation of goods and access to energy sources, which are crucial for industrial activities. Additionally, the concentration of industries in designated townships can help with the management and reduction of industrial emissions, as seen in the EU's efforts to regulate and reduce pollution from large industrial plants.

Overall, industrial townships play a vital role in supporting the needs of industries by offering a range of facilities, services, and incentives, including access to transportation networks and energy resources, thereby fostering economic development and job creation.
