China is infamous for its poor air quality, which has been described as smelling swampy, like a mix of carbon, sewage, vinegar, and cigarettes. This is due to multiple layers of pollution, from coal-fuelled power plant emissions to vehicle exhaust, which have caused a smog problem in the country. Air pollution in China leads to exposure to fine particles in the air that penetrate deep into the lungs and cardiovascular system, causing various diseases. In an effort to detect areas with poor air quality, China has employed people to sniff out harmful levels of pollution, which has been described as unpleasant work.

Air pollution in Beijing
One of the main contributors to Beijing's air pollution is the high number of personal and public vehicles on the roads. These vehicles emit harmful pollutants such as sulphur dioxide, nitrogen dioxide, and other toxic gases, which not only contribute to the overall pollution levels but also create a noxious smell that permeates the city. In addition to vehicle emissions, Beijing's air pollution is also heavily impacted by coal-fired power plants, which account for over 70% of China's energy production. The emissions from these plants release particulate matter, including PM2.5, which are tiny airborne pollutants smaller than 2.5 micrometres in diameter that can penetrate deep into the lungs and cause serious health issues.
The unique combination of pollutants in Beijing's air gives it a distinct and unpleasant odour. Some have described it as a mix of carbon, with a metallic and chemical taste. The smell of rotting garbage, sewage, and construction is also often present, adding to the overall unpleasantness of the city's air. The situation is further exacerbated by unfavourable weather conditions, which can trap the pollutants and create a lingering smog that hangs over the city.
To combat the issue of air pollution, the Chinese government and environmental organisations have implemented various measures. The introduction of better-quality fuel with lower sulphur content, for example, has helped to reduce the emissions from vehicles. Additionally, the government has started to release data on emissions, raising public awareness and empowering people to take action to protect themselves. However, despite these efforts, air pollution remains a significant challenge in Beijing, with the city often experiencing hazardous levels of pollution that affect the health and quality of life of its residents.
To detect areas with poor air quality, China has also employed an interesting method of training people to sniff out harmful levels of pollution. These "professional noses" can distinguish between the smells of harmful environmental pollutants and simply objectionable but harmless odours. While this approach may seem unusual, it showcases the creativity and dedication of those working to address the country's air pollution crisis. Ultimately, air pollution in Beijing remains a complex and pressing issue that requires continued efforts and innovative solutions to ensure a healthier and more sustainable future for the city and its residents.

Shanghai's unique scent
Shanghai's air pollution has a unique scent that is a mix of various factors, creating a distinct and memorable olfactory experience. The city's air pollution has been described as having an underlying note of PM2.5 pollution, a mix of carbon and a hint of an increased cancer risk. This blends with a sooty, metallic, and chemical taste, creating an overall "unique" aroma.
The swampy smell of humid and dirty air is another layer to Shanghai's olfactory landscape. This scent is more prominent during the winter months when the cold and damp conditions intensify the dankness. It creates an unusual sensory experience, leaving a taste on the tongue that is distinct from other cities.
Adding to the complexity of Shanghai's scent is the combination of odours that indicate the proximity of restrooms. The unique blend of poo and cigarettes creates a signature fragrance that is characteristic of the city. This unusual pairing is intertwined with other scents, such as garbage, food, osmanthus blossoms, and sewage, which vary in different areas.
The construction industry also leaves its mark on Shanghai's scent profile. The constant smell of building activities mingles with the other aromas, creating a complex and ever-present backdrop. The air is heavy with the odour of construction, which, when combined with the other scents, forms a potent and lingering aroma.
While the scent of Shanghai is undeniably unique, it is also a reminder of the serious issue of air pollution in the city. The presence of fine particles in the air can have significant health impacts, including respiratory infections and an increased risk of stroke, heart disease, and lung cancer. Shanghai's scent is a complex blend of various factors, creating a sensory experience that is both intriguing and concerning.

Health impact of polluted air
Air pollution in China is a mix of various hazardous substances from both human-made and natural sources. It includes vehicle emissions, fuel oils, natural gas, manufacturing by-products, and power generation, particularly from coal-fueled power plants. These pollutants include particulate matter (PM), carbon monoxide (CO), ozone (O3), nitrogen dioxide (NO2), and sulphur dioxide (SO2). Fine particulate matter, or PM2.5, is of particular concern as it can penetrate deep into the lungs and enter the bloodstream, causing systemic damage to tissues and cells.
The health impact of polluted air is significant and far-reaching. Short-term exposure to high levels of particulate matter can lead to reduced lung function, respiratory infections, and aggravated asthma. Long-term exposure to fine particulate matter increases the risk of stroke, heart disease, chronic obstructive pulmonary disease, and cancer. Air pollution is a major threat to global health, causing more than 6.5 million deaths each year worldwide. In China alone, air pollution is responsible for about 2 million deaths annually.
The impact of air pollution on health can be immediate or cumulative over time. Both short- and long-term exposure to air pollutants can lead to health problems in children and adults. The levels and duration of exposure that are considered safe vary depending on the specific pollutant and the associated disease outcomes. Certain populations are more susceptible to the health effects of air pollution, including children, the elderly, and pregnant women. Maternal exposure to air pollution has been linked to adverse birth outcomes, such as low birth weight, pre-term birth, and small gestational age births.
The pollutants in the air can also affect almost every organ in the body. They can enter the bloodstream through the lungs and circulate throughout the entire body, leading to systemic inflammation and increasing the risk of cancer. Additionally, air pollution has been associated with neurological development issues in children, diabetes, and immune system disorders. Research also suggests that living near major roadways may increase the risk of breast cancer in women.
The health impact of polluted air extends beyond the physical effects on individuals. It also affects economies and people's quality of life. The high number of deaths and illnesses attributed to air pollution has significant social and economic consequences. Furthermore, the sources of air pollution, such as industry, transportation, and power plants, contribute to environmental degradation and climate change, further exacerbating the impact on society as a whole.

China's pollution sniffers
China's air pollution crisis has been well-documented, with the country home to 16 of the 20 most polluted cities in the world. The air pollution is caused by a combination of coal-fuelled power plant emissions, vehicle exhaust, and unfavourable weather conditions, among other factors. This has led to the emergence of "China's pollution sniffers", a team of people trained to detect areas with poor air quality by sniffing out harmful levels of pollution.
The work of these "professional noses" involves distinguishing between the smells of harmful environmental pollutants and simply objectionable but harmless odours. It is an unpleasant task, as team members must repeatedly smell awful gases in a laboratory setting. They are equipped with sensitive electronic equipment that can detect the density of harmful gases in the air, but the human nose and brain are still crucial in building scent profiles and memories.
The use of human detectors has been questioned, as mechanical sensors can often do a better and safer job. However, the human ability to experience and distinguish scents is still not fully understood, and China's pollution sniffers continue to play a role in the country's efforts to tackle its air quality crisis.
The impact of air pollution on people's health cannot be overstated, with an estimated 700,000 people dying annually in China due to poor air quality. The pollution is a mixture of fine particles and noxious gases, including sulphur dioxide and nitrogen dioxide, which penetrate deep into the lungs and cardiovascular system. This has led to a rise in diseases such as stroke, heart disease, lung cancer, and respiratory infections.
While some progress has been made, China's air pollution problem persists, affecting both the economy and the quality of life of its citizens. The government has started to address the issue by implementing stricter fuel standards and releasing data on emissions, but much more needs to be done to improve air quality and protect the health and well-being of those exposed to harmful levels of pollution.
