South Korea's Air Pollution: A Growing Concern?

South Korea's air pollution is a pressing issue, with the country's rapid economic growth contributing to a rise in emissions from fossil fuels, vehicles, and power plants. Seoul, the nation's largest city, has been consistently ranked among the world's most polluted cities, with residents expected to lose up to 1.7 years of life expectancy due to poor air quality. While South Korea points to China's industrial pollution as a significant factor, domestic sources, including coal-fired power plants and vehicle emissions, also play a major role. The Korean government has implemented policies to address this issue, and air pollution levels have shown a decreasing trend in certain regions, but the problem persists, impacting health, sports, and the economy.

Sources of air pollution in South Korea

South Korea's air quality has been decreasing over the years, with the country's rapid growth becoming a major source of air pollution. Fossil fuel combustion is the largest contributor to air pollution in South Korea. The country has very few natural resources and relies heavily on fossil fuels to meet its energy demands, with 38% of its energy coming from oil, 29% from coal, and 15% from gas. This has resulted in high emissions from burning fossil fuels, which release hazardous gases such as oxides of nitrogen, carbon monoxide, particulates, and hydrocarbons into the atmosphere.

The number of vehicles on the road is also increasing, contributing to vehicle emissions, particularly from diesel-powered cars and heavy-duty delivery vehicles. The increase in traffic, factories, and power plants has led to growing pollution in large cities, causing health problems for residents. South Korea's economy has been expanding, leading to a rise in imports and exports, which further contributes to fossil fuel combustion.

In addition to domestic sources, a significant portion of South Korea's air pollution is blown in by prevailing winds from China, especially during the colder winter months when air currents are slower. Dust storms originating from western China and Inner Mongolia bring dust and pollutants into the country, affecting air quality. It is estimated that between 30% and 50% of PM2.5 pollutants in South Korea come from China, with percentages reaching as high as 60% to 80% on bad air quality days.

The South Korean government has recognized the severity of the issue, with the Ministry of Environment regulating 11 air pollutants and 32 other hazardous substances. The government also plans to close 10 of its 61 coal power plants by 2025. To address the problem, South Korea was one of the first countries to adopt the Green Growth Policy, aiming to reduce greenhouse gas emissions and transition to more environmentally friendly alternatives.

Air pollution's impact on health

South Korea's air quality has been decreasing over the years, with Seoul being among the world's cities with the worst air pollution. The main sources of air pollution in South Korea are emissions from burning fossil fuels and vehicle emissions. The impact of air pollution on health is far-reaching, and it is a serious issue that affects people from all walks of life. Here are some of the ways that air pollution impacts health:

Respiratory Issues

Air pollution can cause a range of respiratory problems, including lung cancer, chronic obstructive pulmonary disease (COPD), chronic bronchitis, and asthma. Fine particles in the air, such as those found in wood smoke, can aggravate lung diseases and trigger asthma attacks. Ozone, a powerful lung irritant, can cause inflammation and damage to the delicate lining of the small airways, impacting multiple body systems.

Cardiovascular Diseases

Air pollution has been linked to an increased risk of heart disease, abnormal heartbeats, and cardiovascular diseases. The fine particles found in air pollution can enter the bloodstream and contribute to the development of cardiovascular issues over time.

Neurological Impact

Air pollution has been associated with an increased risk of neurological diseases. Korean researchers have suggested a link between air pollution and Parkinson's disease, as well as other neurological disorders.

Pregnancy and Fetal Development

Pregnant women and their fetuses are particularly vulnerable to the effects of air pollution. Exposure to air pollution during pregnancy can increase the risk of hypertensive disorders, intrauterine inflammation, and damage to the placenta, which can disrupt fetal growth and development. Additionally, exposure to ozone and particle pollution during pregnancy has been associated with premature birth, low birth weight, and stillbirth.

Other Health Issues

Air pollution has been linked to various other health issues, including liver and kidney problems, eye infections, and congenital malformations in the circulatory, musculoskeletal, and genitourinary systems.

The impact of air pollution on health is a serious concern, and it is important to prioritize emission reduction activities and air quality improvement initiatives to mitigate these adverse effects.

Air pollution and sports

South Korea's decreasing air quality has had an impact on several outdoor sports. The Korea Baseball Organization has changed its regulations to allow the cancellation or suspension of a professional baseball game in the event of a severe fine dust warning. The New Delhi marathon is also regularly run in health-threatening conditions.

Air pollution can cause harm to the human body, and this includes athletes. Exposure to ozone can immediately impact athletic performance due to respiratory discomfort. Other pollutants like PM2.5 (particulate matter smaller than 2.5 microns) can impair performance several days after exposure. Training and competing at elevated air pollution levels, even within good-to-moderate classifications, are associated with slower race times.

Studies have shown that among professional Bundesliga players and teenage footballers, poor air quality was associated with a drop in the distance covered, high-intensity effort, and the number of passes. In the US National Football League, the defense team was less effective when PM2.5 concentrations were high. Professional referees are also affected, with the number of arbitration errors increasing by 11% with each 1ppm rise in carbon dioxide and by 2.6% with PM2.5.

Indoor sports activities also expose athletes to specific risks. The air inside and outside of indoor sports facilities can be polluted by small particles and ozone. Yoga, for example, does not tend to resuspend particles and thus has less impact than other activities. High concentrations of VOCs (volatile organic compounds) can come from cleaning products, air fresheners, and even new equipment.

Air pollution control measures

South Korea has been facing issues with air pollution, which has been linked to illness and premature deaths in the country. The main sources of air pollution in South Korea are emissions from burning fossil fuels, vehicle emissions, and coal-fired power plants.

Regulatory Limits and Standards

South Korea has been enforcing regulatory limits on air pollutants and hazardous substances. As of 2020, the country regulates 11 air pollutants and 32 hazardous air substances, up from 11 and 18 respectively in the previous bill. The Korean government has also revised the standards for PM 2.5 fine dust, lowering the acceptable daily and yearly averages. These regulatory changes aim to improve air quality and protect public health.

Coal-Fired Power Plant Retrofitting and Closure

The South Korean government is taking steps to retrofit coal-fired power plants with carbon dioxide capture and storage (CCS), selective catalytic reduction (SCR), and flue gas desulfurization (FGD) systems. These technologies help reduce emissions and improve air quality. Additionally, the government has announced plans to close or renovate several coal-fired power plants by 2034, transitioning to natural gas-fired power plants.

Emission Control Area (ECA) for Ships

South Korea has established an ECA regulation to tackle port and shipping air pollution, which accounts for 10% of local air pollution sources. The ECA regulation includes measures such as stricter marine fuel standards, vessel speed restrictions, prohibiting old diesel vehicles from entering port areas, and encouraging the use of liquefied natural gas instead of diesel. These measures aim to significantly reduce fine particulate pollution at ports.

Air Quality Improvement Act

The National Assembly passed the Special Act on Air Quality Improvement in Port and Other Areas to combat air pollution from shipping and port activities. This act stipulates a series of measures to reduce air pollution and protect human health, not just in South Korea but also in the region.

Air Pollution Control Industry

The South Korean government has recognized the importance of the air pollution control market, which was worth billions of dollars in recent years. The government plans to lower fine dust concentration by over 35% by 2030 compared to 2018 levels. The Air Pollution Control Equipment Industry and related industries play a significant role in providing solutions to improve air quality.

Public Awareness and Protection

The decreasing air quality in South Korea has impacted outdoor activities and sports. The use of pollution masks is a popular and affordable method for protection, although they may not be eco-friendly or comfortable for long-term use. The Korea Baseball Organization has even changed its regulations to allow the cancellation or suspension of games due to severe fine dust warnings.

Air pollution's economic impact

South Korea's air quality has been decreasing over the years, with Seoul being among the world's cities with the worst air pollution. The main sources of air pollution in South Korea are emissions from burning fossil fuels and vehicle emissions. The growth of imports and exports in South Korea's fast-growing economy has also increased fossil fuel combustion. The country's air pollution has had a significant impact on its economy, with local studies estimating the economic damage caused by lost production at about $9 billion annually—a figure predicted to double by 2060.

Air pollution has far-reaching economic implications, from healthcare costs associated with pollution-related illnesses and deaths to environmental damage and lost ecosystem services. It also leads to decreased workplace productivity and a decline in tourism, affecting economies worldwide. The World Bank estimates that the health damage caused by air pollution costs $6 trillion annually, resulting in a 5% reduction in global GDP due to health impacts, lost productivity, and reduced life expectancy.

The costs of air pollution are not limited to direct healthcare expenditures. Poor air quality impacts talent recruitment, as cities with severe air pollution are less desirable places to work. Companies may even offer hardship-posting compensation for employees relocating to cities with dangerous air pollution levels. Additionally, air pollution hampers workforce productivity, with 1.2 billion workdays lost globally each year, which could reach 3.8 billion by 2060.

However, addressing air pollution can have significant economic benefits. Studies show that air pollution control measures are effective and offer a substantial return on investment. For example, research on the Clean Air Act in the United States found a 30:1 ratio between the economic gains and the costs of pollution mitigation. Similarly, air pollution reduction has boosted the EU economy by €50-60 billion annually since 2014.
