Air Pollution In China: Understanding The Complex Causes

Air pollution in China is a major public health issue, causing an estimated 2 million deaths per year. The burning of fossil fuels, particularly coal, is a key contributor to this, alongside industry, transportation, and household solid fuel usage. In recent decades, China's rapid development has led to excessive emissions of greenhouse gases, with over 40% of cities exceeding national standards for air quality. While some progress has been made, air pollution remains a pressing concern, impacting the health and quality of life of Chinese citizens.

Burning of fossil fuels, especially coal

The burning of fossil fuels, especially coal, is a major contributor to air pollution in China. Over the past three decades, China's rapid development has resulted in excessive emissions of greenhouse gases. In northern China, air pollution from the burning of fossil fuels, principally coal, is causing people to die on average 5.5 years sooner than they might otherwise.

Coal power plants, along with industry, transportation, and household solid fuel usage, are major contributors to air pollution. In 2007, a World Bank report found that outdoor air pollution was causing 350,000 to 400,000 premature deaths a year in China. A draft of the same report put the figure at 760,000 premature deaths per year. The Chinese Academy for Environmental Planning determined that air pollution was responsible for 411,000 premature deaths across China in 2003.

Air pollution in China is not only a domestic issue but also an international one. The air pollution issue in China impacts its Asian neighbours, such as Japan and South Korea, as well as the West Coast of the United States. This is due to the spread of pollution by Westerly winds.

China has made significant progress in reducing air pollution in recent years. In 2016, only 84 out of 338 prefecture-level or higher cities attained the national standard for air quality. However, air pollution remains at an alarming rate in China and affects economies and people's quality of life. It is responsible for about 2 million deaths in China per year.

Industry and transportation

China's air pollution is largely coal-derived, with the burning of fossil fuels, principally coal, causing people to die on average 5.5 years sooner than they otherwise might. In 2007, a World Bank report found that outdoor air pollution was causing 350,000 to 400,000 premature deaths a year in China.

In addition to coal power plants, industry and transportation are major contributors to air pollution in China. The Chinese Academy for Environmental Planning determined that air pollution was responsible for 411,000 premature deaths across China in 2003. The 2008 Olympic Summer Games in Beijing was a catalyst for many new policies to address air pollution. Emergency measures were enacted depending on pollution levels, but the most important factor in curbing air pollution is the implementation of new laws and the reformation of old ones.

Air pollution in China has far-reaching consequences, impacting not only its Asian neighbours but also the West Coast of the United States. It contributes to increasing levels of greenhouse gases in the Earth's atmosphere as a whole.

Household solid fuel usage

The use of solid fuels in households is a major contributor to air pollution in China. Solid fuels, such as coal, are burned for cooking and heating, and the resulting emissions contain fine particles that can penetrate deep into the lungs and cardiovascular system. This type of household air pollution is responsible for a significant number of deaths in China each year, with an estimated one million deaths attributed to the use of polluting fuels and technologies for cooking alone.

The burning of fossil fuels, particularly coal, is a significant issue in northern China, where it is causing people to die on average 5.5 years sooner than they otherwise might. This is due to the high levels of air pollution that are created when fossil fuels are burned, which can lead to an increased risk of respiratory diseases, stroke, heart disease, lung cancer, and other serious health issues.

China's rapid development over the past three decades has resulted in excessive emissions of greenhouse gases, with more than 40% of the major air pollutant concentrations in 337 cities exceeding Chinese standards. While China has made some progress in reducing air pollution in recent years, it remains a significant public health issue, impacting not only China but also its Asian neighbours and the West Coast of the United States.

To address the issue of household solid fuel usage and reduce air pollution, it is important to implement measures that promote the use of cleaner and more sustainable energy sources for cooking and heating. This may include providing access to alternative fuels, such as liquefied petroleum gas or electricity, and improving the energy efficiency of homes to reduce the overall demand for energy. Additionally, raising awareness about the health risks associated with solid fuel usage and providing education on proper fuel handling and ventilation practices can help reduce exposure to harmful pollutants.

Greenhouse gas emissions

China's rapid development over the past three decades has resulted in excessive emissions of greenhouse gases. This has contributed to increasing levels of greenhouse gases in the Earth's atmosphere as a whole. In northern China, air pollution from the burning of fossil fuels, principally coal, is causing people to die on average 5.5 years sooner than they might otherwise.

Industry, transportation, coal power plants and household solid fuel usage are major contributors to air pollution. In 2007, a World Bank report conducted with China's national environmental agency found that outdoor air pollution was causing 350,000 to 400,000 premature deaths a year. Indoor pollution contributed to the deaths of an additional 300,000 people. In 2003, the Chinese Academy for Environmental Planning determined that air pollution was responsible for 411,000 premature deaths across China. More recently, air pollution has been responsible for about 2 million deaths in China per year. Of those deaths, ambient air pollution alone caused more than 1 million deaths, while household air pollution from cooking with polluting fuels and technologies caused another million deaths in the same period.

Air pollution is a major public health issue in China. It has been linked to lower birth rates and higher adult mortality from respiratory-related diseases. Lung cancer rates have risen over 60% in the past decade, although the smoking rate has not increased. In the past, emergency measures were enacted depending on the pollution levels, but the most important factor in curbing air pollution is the implementation of new laws and the reformation of old laws. In recent years, China has made significant progress in reducing air pollution. In 2016, only 84 out of 338 prefecture-level or higher cities attained the national standard for air quality.

Water-borne pollution

China's water supply has been contaminated by the dumping of toxic human and industrial waste. Half of China's population cannot access water that is safe for human consumption and two-thirds of China's rural population relies on tainted water. Pollution-induced algae blooms cause the surface of China's lakes to turn a bright green, but greater problems may lurk beneath the surface; groundwater in 90% of China's cities is contaminated. China's coastal manufacturing belt faces the most pollution.

Water pollution in China has doubled from what the government originally predicted because the impact of agricultural waste was ignored. Farm fertiliser has largely contributed to water contamination. China's water sources contain toxic levels of arsenic, fluorine and sulfates, and pollution has been linked to China's high rates of liver, stomach and oesophageal cancer.

China's extraordinary economic growth, industrialisation, and urbanisation, coupled with inadequate investment in basic water supply and treatment infrastructure, have resulted in widespread water pollution. In China today, approximately 700 million people—over half the population—consume drinking water contaminated with levels of animal and human excreta that exceed maximum permissible levels by as much as 86% in rural areas and 28% in urban areas.

Water pollution in China stems from the demand for cheap goods; multinational companies ignore their suppliers' environmental practices. Although combating water pollution in China will require much more work, continued efforts from organisations like the Detox campaign provide a beacon of hope for the future of China's people and environment.
