What You'll Learn
Air pollution kills 4,000 people daily in China
Air pollution in China is a pressing issue, causing widespread environmental and health problems. According to a 2015 study by physicists at the University of California, Berkeley, approximately 4,000 people in China die daily due to polluted air. This equates to around 1.6 million deaths per year from heart, lung, and stroke problems caused by air pollution.
The issue is exacerbated by China's industrialization and population growth, and certain seasonal factors. The burning of coal for heating during the winter, coupled with weather conditions that trap dirty air, significantly contributes to the high levels of air pollution. As a result, nearly all of eastern China experiences higher levels of small particle haze than the worst-affected areas in the United States.
The health implications of air pollution in China are severe. Fine particles in polluted air penetrate deep into the lungs and cardiovascular system, causing various diseases. These include stroke, heart disease, lung cancer, chronic obstructive pulmonary diseases, and respiratory infections. The World Health Organization estimates that ambient air pollution alone caused over a million deaths in China in a given year, while household air pollution from cooking with polluting fuels and technologies caused another million deaths during the same period.
The Chinese government has acknowledged the severity of the problem. In 2003, the Chinese Academy of Environmental Planning produced an internal report estimating that 300,000 people died annually from ambient air pollution. By 2005, Chinese environmental experts projected that annual premature deaths attributable to outdoor air pollution could reach 550,000 by 2020. These reports highlight the growing recognition of the issue within the country.
The impact of air pollution in China extends beyond its borders. Sulfur dioxide and nitrogen oxides from China fall as acid rain on cities like Seoul, Tokyo, and even Los Angeles. Addressing air pollution in China is not just a domestic concern but a global imperative.

China's pollution reaches other countries
China's pollution problem has been well-documented, with various forms of pollution increasing following the country's industrialization, causing widespread environmental and health issues. Air pollution in China is responsible for about 2 million deaths per year, with indoor pollution contributing to an additional 300,000 deaths and another 60,000 dying from water-borne diseases. The country's pollution problem has also spread internationally, with sulfur dioxide and nitrogen oxides falling as acid rain on Seoul in South Korea and Tokyo, Japan, and even reaching Los Angeles in the United States.
China is the world's largest emitter of anthropogenic air pollutants, and its emissions are transported through the atmosphere to other countries, including the United States. A study found that in 2006, about 21% of export-related Chinese emissions were attributed to exports to the US. Atmospheric modeling has shown that the transport of these emissions contributes to the annual mean surface sulfate concentrations and ozone levels over the western US.
The production of goods for foreign consumption is a significant contributor to China's emissions. For example, the manufacture of goods for export has been associated with the emission of sulfur dioxide, nitrogen oxides, carbon monoxide, and black carbon. International trade with polluting industries in China and other emerging economies also plays a role in sustaining global consumption while impacting air pollution levels.
China has taken steps to address its pollution problem, such as implementing a ban on plastic bags in 2008 and declaring a "war against pollution" in 2014. Since then, the country has made remarkable progress, with pollution levels down by 41% compared to 2013. However, challenges remain, as pollution levels still exceed the World Health Organization's (WHO) guidelines, shortening the life expectancy of Chinese residents.

Soil pollution has impacted China's food safety
Pollution in China has had devastating consequences, with air pollution alone causing the premature deaths of 350,000–500,000 people annually. Soil pollution, in particular, has severely impacted China's food safety, threatening human health and agricultural sustainability.
Soil pollution has become an increasingly pressing issue in China, with far-reaching implications for food safety and public health. The country's rapid industrialization and population growth have contributed to the contamination of soil, posing significant risks to the food chain.
China's agricultural sector heavily relies on agrochemicals, including chemical fertilizers and pesticides, to boost crop production and meet the demands of its large population. However, this has resulted in intensive but inefficient agrochemical consumption, leaving large amounts of residue in the soil and plants. This residue contains persistent organic pollutants and endocrine disruptors, impairing plant metabolism and contaminating crops.
Heavy metal pollution of cropland is another significant concern. Mining, smelting, sewage irrigation, sludge reuse, and fertilizer application have led to approximately 10.18% of China's cropland being polluted by heavy metals, affecting 13.86% of grain production. This heavy metal pollution, especially cadmium, poses a severe risk to food safety and has been linked to negative health outcomes, including cancer.
Water scarcity has further exacerbated the situation, as farmers have resorted to using wastewater irrigation, leading to the contamination of agricultural land and food crops. The overuse of pesticides has also left residues in grain, directly impacting public health through food consumption and contributing to diet-related diseases.
The Chinese government has recognized the urgency of addressing these issues and has implemented various measures over the years. These include improving chemical fertilizer structures and fertilization technology, detecting pesticide and veterinary drug residues in agricultural products, and registering fertilizers and pesticides to track their impact on the environment. However, the challenge of ensuring food safety in the face of soil pollution remains complex and ongoing.

China's pollution is caused by industrialisation
China's rapid industrialisation has led to a significant increase in various forms of pollution, causing severe environmental and health issues. The country's economic growth and expansion in production for export have resulted in a surge of energy-intensive industrial products, contributing to air, soil, and water pollution.
One of the primary consequences of industrialisation in China is air pollution, which has reached alarming rates. Fine particles in the polluted air penetrate the lungs and cardiovascular system of individuals, leading to health issues such as stroke, heart disease, lung cancer, respiratory infections, and other respiratory illnesses. According to the Chinese Ministry of Health, industrial pollution has made cancer the leading cause of death in China. Air pollution is responsible for about 2 million deaths annually, with ambient air pollution causing more than a million of those deaths.
The burning of fossil fuels, particularly coal, in northern China, has severe health implications. It causes people to die, on average, 5.5 years sooner than expected. Additionally, seven of the ten most air-polluted cities in the world are in China, including Beijing, where the 2008 Summer Olympics were held. The pollution is not contained within China's borders; it spreads internationally, with sulfur dioxide and nitrogen oxides falling as acid rain on Seoul, South Korea, and Tokyo, and even reaching Los Angeles in the US.
Soil pollution has also intensified due to industrialisation and population growth. Approximately 38,610 square miles (100,000 km2) of China's cultivated land is polluted, with contaminated water used for irrigation, posing threats to the environment, food safety, and sustainable agriculture. Solid waste has covered or destroyed an additional 2 million square miles (1,300 km2) of land. As a result, an estimated 6 million tonnes of food grain are contaminated by heavy metals annually, causing substantial economic losses.
Water pollution is another pressing issue, with 500 million people lacking access to safe and clean drinking water. This has led to various diseases, including diarrhea, bladder and stomach cancer, contributing to premature deaths.
China has recognised the severity of its pollution problem and has implemented measures such as banning plastic bags, restricting the importation of electronic waste, and launching initiatives like Operation National Sword to monitor and regulate recyclable waste imports. However, more substantial improvements in energy efficiency and emission control technologies are necessary to reduce transboundary pollution and improve the health and quality of life for people in China and beyond.

China's pollution is the worst in winter
China's air pollution is a pressing issue that has gained international attention. The country's rapid industrialisation, population growth, and reliance on coal have led to severe environmental and health consequences, especially during the winter months.
During winter, China experiences a surge in air pollution due to several factors. Firstly, the burning of coal for heating purposes significantly contributes to the problem. The Huai River Policy, implemented between 1950 and 1980, provided free coal for winter heating in the northern region. This policy led to a sharp increase in coal consumption and production, with coal now accounting for 70% of China's total energy consumption. The combustion of coal releases harmful pollutants such as carbon dioxide, sulfur dioxide, nitrogen oxide, and particulate matter (PM2.5 and PM10).
Secondly, winter weather conditions play a crucial role in exacerbating air pollution. Temperature inversions, a common occurrence during winter, trap pollutants and prevent their dispersion, leading to the formation of severe smog. This phenomenon is particularly prevalent in northern China, where industrial emissions, coal production, and heating demands are highest.
The health impacts of China's winter air pollution are dire. According to various studies and reports, air pollution in China contributes to approximately 1.6 million to 2 million premature deaths annually. The pollutants in the air increase the risk of heart disease, lung cancer, stroke, and other respiratory illnesses. The situation is so severe that it has gained the attention of the World Bank, which has conducted reports in collaboration with China's national environmental agency.
To address the winter air pollution crisis, China has implemented several measures. The Winter Action Plan aims to control heavy pollution by setting short-term targets during peak seasons for regions with higher pollution risks. While this plan has shown some effectiveness, there have been concerns about inconsistent enforcement, as evident in 2022 when the plan's absence led to a 7.0% year-on-year increase in PM2.5 levels in the first quarter of 2023.
Moving forward, China must continue to prioritise air quality improvements to protect its citizens' health and well-being. This includes strengthening the enforcement of existing policies, transitioning to renewable energy sources, and implementing stricter pollution standards, especially during the critical autumn and winter seasons.
