Air pollution is a significant problem in China, with fine particles in the air causing respiratory and cardiovascular issues, including stroke, heart disease, and lung cancer. The impact of air pollution on mortality rates is evident, with an estimated 1.6 million people dying annually from related causes. A study from 2012 attributed a large fraction of damage to Chinese citizens' health to these fine particles, which are caused by the burning of fossil fuels and result in smog. China's rapid population and economic growth, coupled with lax environmental oversight, have exacerbated water shortages and pollution, further impacting health. Soil pollution, contaminated by heavy metals, also affects one-tenth of China's cultivable land, causing adverse health effects and economic losses. While efforts to control emissions have decreased pollution in recent years, PM2.5 concentrations still exceed WHO guidelines, and air pollution remains a critical issue affecting the health and economy of China.

Air pollution is a fundamental problem in China, causing 2 million deaths per year
Air pollution is a critical issue in China, causing around 2 million deaths per year. It is a leading cause of death globally and poses a threat to both China's people and the world's economy.
Air pollution in China is caused by a range of factors, including industry, transportation, coal power plants, and household solid fuel usage. The population growth in China since the 1980s has also contributed to increased soil pollution. Despite some progress in reducing emissions, air pollution remains alarmingly high. According to the World Health Organization (WHO), PM2.5 concentrations in China exceed the Air Quality Guideline, with 81% of the population living in regions exceeding the Interim Target 1.
The health consequences of air pollution in China are severe. Fine particles in the polluted air penetrate deep into the lungs and cardiovascular system, causing diseases such as stroke, heart disease, lung cancer, chronic obstructive pulmonary diseases (COPD), and respiratory infections. A 2013 study found that severe pollution during the 1990s reduced life expectancy by 5.5 years in northern China. More recently, in 2017, an estimated 1.24 million people died from air pollution in China, with an additional 30 million deaths attributed to air pollution since 2000. The mortality rate varies across provinces, with a higher rate in Tibet due to household pollution and a lower rate in Shanghai.
Overall, air pollution in China has had a significant impact on mortality rates, contributing to about 2 million deaths annually and causing severe health issues. While some progress has been made in reducing emissions, further efforts are needed to improve air quality and protect the health and well-being of China's citizens.

Water pollution is also an issue, with 60,000 premature deaths each year
Water pollution is a significant issue in China, causing approximately 60,000 premature deaths each year. This is primarily due to the severe water quality issues in the country, with much of the water being contaminated and unfit for human consumption. According to a national survey in 2006, only about half of the 60,000 rural households surveyed had access to a centralised public water supply, with the rest relying on untreated hand pumps, wells, or surface water sources.
The lack of access to safe drinking water is a pressing issue in China, with 500 million people lacking access to clean drinking water. This has severe health implications, with exposure to microbial pollutants causing chronic health issues. The World Bank has noted that China's waterways are seriously contaminated by industrial discharges, rendering them largely unfit for direct human use. This is supported by a 1997 report that attributes hundreds of thousands of premature deaths to industrial air pollution, which also affects water quality.
In addition to industrial pollution, plastic waste is a significant contributor to water pollution in China. China holds around 20% of the global share of mismanaged plastic waste, which eventually ends up in oceans and waterways. The Yangtze River, Asia's longest river, has become one of the biggest sources of global plastic pollution. This is a critical issue as the river basin supports nearly one-third of the country's population.
China has made efforts to address water pollution, with reported reductions in annual emissions of arsenic and mercury and the construction of industrial wastewater treatment plants. However, the complexity of the water quality monitoring system and the lack of transparency in data have hindered the documentation of improvements. Despite these challenges, China is making progress in environmental protection, with increases in forest cover and reductions in air and water pollution.

Soil pollution has contaminated 38,610 sq mi of cultivated land, threatening food safety
China has witnessed a significant decline in air pollution in recent years, attributable to extensive emission control efforts. However, pollution levels remain a critical concern, exceeding the WHO Air Quality Guidelines. Air pollution has been linked to increased mortality rates in China, with an estimated average life expectancy increase of 1.25 years if pollution levels were reduced to the minimum threshold.
While air pollution has dominated the discourse on environmental concerns in China, soil pollution has emerged as an equally pressing issue. Soil pollution, caused by unsustainable agricultural practices, improper waste disposal, mining, and other factors, has contaminated 38,610 sq mi of cultivated land, posing a severe threat to food safety and sustainability. This contamination has detrimental effects on crop yields and the safety of food produced for human and animal consumption, impacting food security and human health.
The agricultural use of pesticides, industrial and urban pollution, and airborne soil contamination contribute to the degradation of soil quality. Hazardous substances, such as heavy metals, organic chemicals, and pesticides, infiltrate the soil, reducing the number of beneficial microorganisms and rendering the soil incapable of supporting healthy crop growth. This, in turn, leads to reduced food production and contaminated food crops, exacerbating food security concerns.
The consequences of soil pollution extend beyond the immediate impact on food. Contaminants in the soil can leach into groundwater, causing further pollution and posing risks to human health. Additionally, soil pollution disrupts ecosystems, affecting biodiversity, water regulation, nutrient recycling, and climate change mitigation.
Addressing soil pollution requires a multifaceted approach. Implementing regulations, promoting sustainable agricultural practices, and improving soil management are essential steps in mitigating the adverse effects of soil pollution on food safety and the environment. Individual actions, such as reusing and recycling items, also play a role in reducing land pollution and its impact on cultivated land.

White pollution is a term unique to China, referring to plastic waste
China's rapid industrialization has resulted in intense levels of pollution, presenting serious social, economic, and political problems. Air pollution in China has been linked to millions of premature deaths worldwide each year, with the average life expectancy in China being 1.25 years lower than it would be if pollution levels were safe. According to the Chinese Ministry of Health, industrial pollution has made cancer the leading cause of death in China.
The term "white pollution" is unique to China and refers specifically to plastic waste. The name refers to the colour of white plastic shopping bags, Styrofoam containers, and other light-coloured materials that began appearing in agricultural fields, landscapes, and waterways in the mid-to-late 1990s. The first official use of the term "white pollution" was in 1999 when the State Council imposed the first bans.
China's pollution problem is not limited to air pollution and plastic waste. Soil pollution has also increased due to the country's immense population growth since the 1980s, threatening the environment, food safety, and sustainable agriculture. Additionally, China's waterways have been severely contaminated by industrial discharges, rendering them largely unfit for human use.
To combat air pollution, China has implemented measures to improve air quality, such as reducing coal consumption and emissions. These efforts have shown some success, with a 23.6% decrease in PM2.5 in 74 key cities between 2013 and 2015. However, PM2.5 concentrations still exceed the WHO Air Quality Guidelines, and air pollution remains a significant risk factor for the Chinese population.

Electronic waste is a growing problem, with China producing 2.3 million tons in 2011
Electronic waste, or e-waste, is a critical and growing environmental issue, with China producing 2.3 million tons in 2011. E-waste is any discarded product with a plug or battery, and it contains toxic additives or hazardous substances such as mercury, which can damage the human brain and coordination system. The rapid increase in the use of electrical and electronic equipment worldwide has resulted in a corresponding increase in e-waste, and China is one of the leading producers of such equipment.
The amount of annual domestic e-waste generation in China alone reaches approximately 10.1 million tons, overtaking the US as the largest e-waste-producing country. This overtaking was expected given China's rising economic development, technical innovation, and urbanization, as more electronics are being created, consumed, and disposed of. E-waste from computers, mobile phones, and other electronics is expected to rise to 27.22 million tons by 2030, growing at an average annual rate of 10.4%. The major sources of e-waste in China are households, domestic institutions such as schools and hospitals, government agencies and businesses, and equipment manufacturers.
The improper disposal of e-waste has led to soil and sediment pollution, especially in the Taizhou region of the Zhejiang province, a major e-waste recycling center. Residents of Taizhou are vulnerable to contamination of their large agricultural sector by toxins generated from e-waste disposal. They also have a high dietary intake of heavy metals through rice, vegetables, and water consumption, exceeding the FAO tolerable daily intake.
To address the e-waste problem, the Chinese government has implemented various environmental legislations and programs to regulate the electronic product production and e-waste management sectors. In 2011, the Collection and Treatment Decree on Wastes of Electric and Electronic Equipment strengthened national standards for the e-waste treatment sector, setting minimum annual treatment capacities for formal e-waste treatment enterprises. In 2012, China adopted the extended producer responsibility (EPR) system, which holds manufacturers responsible for the collection and recycling of electronics. While these measures have helped, the overall mortality attributable to air pollution in China only decreased slightly between 1990 and 2017, with 12 provinces showing an increasing trend.
