Air pollution in Northeast China
Northeast China, covering 787,300 square kilometers of land, has suffered from serious air pollution for a long time. The region has a unique geographical location and a heavy industrial structure, which has led to annual air pollution. In the past 50 years, the average number of haze days in Northeast China has increased significantly. The region is sometimes referred to as China's Rust Belt, as it is a traditional old industrial base and an important agricultural area.
The major sources of air pollution in big cities are traffic-related air pollutants (TRAPs), which are a mixture of combustion-derived particulate matter (PMs), diesel exhaust particles (DEPs), and gaseous emissions. In Northeast China, small respirable particulate (PM2.5) pollution constitutes a significant component of air pollution, which spreads from Liaoning Province to Heilongjiang Province via Jilin Province. The latest studies have also suggested that the burning of agricultural straw has become one of the prominent sources of air pollution, causing frequent seasonal haze events during late autumn or early spring with the highest hourly PM2.5 concentrations higher than 1000 μg m−3.
The Chinese government implemented an air pollution prevention and control program from 2013 to 2017, and although some public health results were achieved, heavy air pollution remained during this period, especially in the northeast of the country. Coal is a huge issue in China, as it accounts for 70% of the total energy consumption, and emissions from coal combustion are the major contributors to air pollution. Coal production, alongside rapid economic growth, has increased the emission of harmful pollutants such as carbon dioxide, sulfur dioxide, nitrogen oxide, and small particle matter known as PM2.5 and PM10. Long-term exposure to these pollutants can cause serious health risks such as respiratory diseases, cancer, and cardiovascular and cerebrovascular diseases.
To combat the air pollution problem in Northeast China, regional joint pollution prevention and control measures should be adopted, and different treatment measures should be developed for different cities based on their roles in the pollution network. Social Network Analysis (SNA) is a new method for studying relational networks and can be used to understand the structure of air pollution transmission networks and propose targeted policy recommendations.

The impact of industrialisation
China's industrialization has had a significant impact on the environment and public health, with various forms of pollution increasing since the country's industrialization. This has resulted in widespread environmental degradation and health issues.
One of the most notable impacts of industrialization in China is the increase in air pollution. Coal combustion, for instance, is a major contributor to air pollution in the country, with coal accounting for 70% of total energy consumption. The Huai River Policy, implemented between 1950 and 1980, provided free coal for winter heating in the northern region, leading to a surge in coal consumption and production. As a result, emissions of harmful pollutants, such as carbon dioxide, sulfur dioxide, nitrogen oxide, and particulate matter (PM2.5 and PM10), have increased. These pollutants have been linked to respiratory diseases, cancer, and cardiovascular and cerebrovascular diseases.
In addition to air pollution, industrialization has also affected water quality in China. The development of infrastructure and the growth of megacities have led to increased water pollution, with many groundwater aquifers contaminated by industrial wastewater. The Huai River Basin in Shandong Province, for example, has been severely impacted by industrial pollutants, with coal, papermaking, and construction materials identified as high-pollution industries.
Soil pollution has also intensified due to industrialization and population growth. Approximately 38,610 square miles (100,000 km2) of China's cultivated land is polluted, and contaminated water is used for irrigation, further exacerbating the problem. This has raised concerns about food safety and sustainable agriculture, with an estimated 6 million tonnes of food grains contaminated by heavy metals annually.
Moreover, industrialization has contributed to the decline of certain industries and economic stagnation in Northeast China. This region, known as China's Rust Belt, has experienced negative spatial co-movements, indicating competition among neighbouring regions following the bankruptcy of secondary industry enterprises. The dominant movements suggest that most northeastern cities have lost their income positions relative to their neighbours.
China has taken some steps to address pollution, such as signing the Stockholm Convention to control and phase out persistent organic pollutants (POPs) and implementing a ban on plastic bags in 2008. However, the country continues to face challenges in effectively controlling and eliminating various forms of pollution.

Water pollution
China's water resources are affected by severe water shortages, a growing population, rapid economic development, and lax environmental oversight, which have increased water demand and pollution on a large scale. China is one of the world's leading water consumers, withdrawing roughly 600 billion cubic meters of water annually. The country's per-capita water supply is a quarter of the world average, with half of its cities facing water shortages to varying degrees.
Inadequate water quality exacerbates China's water scarcity, which is unevenly distributed across the country. The southern and eastern regions enjoy abundant rainfall, while the northern and western regions receive very little. This results in some provinces battling floods while others suffer from months-long droughts. The uneven distribution of water also affects the north and south regions, with the north being significantly more arid and the south more moist. The production of grain has gradually shifted from the south to the north, exacerbating the problem and causing the water table to drop by 1.5 meters per year in parts of the northern portion of the country.
China has responded to its water crisis by rapidly building out water infrastructure, increasing regulation, and exploring technological solutions. The central government has issued stricter regulations on pollutants and spent billions of dollars on water projects, but water quality remains generally poor. The Ministry of Environment has also stepped up efforts to address water pollution, ordering provinces to meet their water quality targets. However, local governments have often failed to crack down on polluting industries, and water pollution data is not always publicly available, making it difficult to hold local governments accountable.

Health risks
China's pollution problem has been well-documented over the years, with the country facing various forms of pollution that have resulted in widespread environmental and health issues. Northeast China, in particular, has suffered from serious air pollution due to inadequate production technology, industry, coal-burning for heating in winter, and the burning of agricultural straw.
The health risks associated with pollution in Northeast China are significant and wide-ranging. Long-term exposure to pollutants can lead to respiratory diseases, cancer, cardiovascular and cerebrovascular diseases, and gastrointestinal issues. The Chinese Ministry of Health has declared that industrial pollution has made cancer the leading cause of death in China. Ambient air pollution alone kills hundreds of thousands of citizens annually.
In addition to cancer, respiratory issues are a major concern. The high levels of PM2.5 and PM10 in the air, resulting from coal combustion and agricultural burning, can cause respiratory diseases and exacerbate existing conditions. These fine particles can penetrate deep into the lungs and even enter the bloodstream, causing or contributing to a range of health problems.
Another health risk is the impact on cardiovascular health. The pollution in Northeast China contains high levels of carbon dioxide, sulfur dioxide, nitrogen oxide, and other harmful pollutants. These pollutants can contribute to an increased risk of cardiovascular and cerebrovascular diseases, including heart disease and stroke.
The pollution also affects the agricultural sector, with an estimated 6 million tonnes of food grain contaminated by heavy metals every year. This not only results in economic losses but also poses risks to food safety and sustainable agriculture. The consumption of contaminated food can lead to various health issues, including gastrointestinal problems and the disruption of thyroid function.
Furthermore, the poor air quality in Northeast China has been linked to allergic conjunctivitis. A 5-year study found a positive correlation between the incidence of allergic conjunctivitis and atmospheric pollutants, with an average growth rate of 7.6% per annum.
Overall, the health risks associated with pollution in Northeast China are extensive and impact various aspects of public health. While China has made some efforts to improve its environmental quality, the health consequences of pollution remain a critical challenge that requires further attention and comprehensive solutions.

China's environmental improvement efforts
China's environmental crisis, the result of decades of rapid industrialization and population growth, has led to air, water, and soil pollution. As the world's largest source of greenhouse gas emissions, China's carbon emissions threaten global efforts to fight climate change. The country's environmental degradation also endangers economic growth, public health, and government legitimacy.
China has been taking steps to address these issues and improve its environmental performance. For instance, China is a signatory to the Stockholm Convention, a treaty aimed at controlling and phasing out persistent organic pollutants (POPs). As part of this treaty, China has committed to eliminating the production, import, and use of certain pesticides and establishing an inventory of POP-contaminated sites.
Another significant step taken by China was the ban on plastic bags in 2008. Supermarkets, department stores, and shops were prohibited from providing free plastic bags, encouraging the use of cloth bags instead. This ban has contributed to a 10% reduction in plastic bag waste in the year following its implementation.
China is also transitioning from coal to renewable energy sources. In 2019, renewables accounted for nearly 15% of China's energy mix, an increase from 7% a decade earlier. The country has been utilizing hydropower for years and is now installing more solar panels and wind power generators.
China has set ambitious targets for the future, aiming for carbon neutrality by 2025. The Chinese Communist Party (CCP) has outlined a comprehensive plan for economic restructuring and technological advancements by 2035, with a focus on sustainability and environmental improvement.
