Well not exactly!
After receiving global criticism for its deteriorating air quality, the country was on war foot to reduce it,
and surprised the world!
How?
Flashback To Chin’s Air Pollution!
In an attempt to showcase its development and grand entrance to the world, China hosted its first-ever Olympic games in 2008.
Over 10000 athletes from Over 200 countries participated in this event in Beijing. And yet, even when its image mattered the most, China still couldn’t control its pollution.
The city was covered in its signature, dangerously thick, grey smog. In 2013, China experienced some of its highest pollution levels to that point, and public criticism reached new heights.
Will India surpass China to become the next superpower?
So as India’s Air Pollution
As many of you know, major cities like New Delhi are currently facing severe air pollution challenges, and it’s crucial that we find effective solutions. So, let’s explore how India can learn from China’s experience.
The Chinese government initiated a National Air Quality Action Plan in the fall of 2013, laying out specific targets to improve air quality by the end of 2017.
The plan included a $270 billion initiative to reduce annual average PM2.5 concentrations in the densely populated Beijing-Tianjin-Hebei area by 25 percent, and in the Pearl and Yangtze River Delta regions by 15 and 20 percent, respectively.
Their comprehensive approach included measures such as improving industrial emissions, promoting renewable energy sources, and encouraging the use of electric vehicles.
Let’s take a moment to compare the air pollution charts of India and China. As you can see, there is a stark contrast. China’s proactive measures resulted in a steady decline in pollution levels, while India continues to struggle with high pollution levels. If the reductions are sustained, China’s people can expect to live 1.4 years longer.
How Could China Be Able To Overcome Air Pollution?
Let’s explain it in 10 steps that China took to control air pollution same can be replicated by any country struggling with bad air quality.
1. Reducing the no of vehicles on the road:
Lottery to buy a car
In Beijing, You Have to Win a License Lottery to Buy a New Car
Yes, you read it right!
Cities such as Beijing, Guangzhou, and Guiyang have only a small number of new license plates, which they issue through a lottery system.
To address the growing number of vehicles on the roads, especially in major cities, the Chinese government introduced a system that limits the issuance of new vehicle registrations through a lottery system.
Here’s how the lottery system for vehicle registration works:
1. Limited vehicle registration quotas:
The government sets a specific number of vehicle registration quotas available for a given period, typically annually or monthly, depending on the city.
2. Eligibility through a lottery:
Individuals interested in purchasing a new vehicle must participate in the lottery system to secure a registration slot.
The odds of winning the lottery are so low that locals joke about winning the actual lottery!
3. Incentives for cleaner vehicles:
Some cities in China provide additional incentives within the lottery system to encourage the purchase of electric and hybrid vehicles. These incentives can include higher chances of winning a registration slot or special benefits for owners of eco-friendly vehicles.
4. Monitoring and enforcement:
The government closely monitors the lottery system to ensure its effectiveness and prevent any fraudulent activities or misuse of registration slots.
Auctions for New License Plates
Auctions for new license plates in Shanghai
In contrast, Shanghai takes a different approach by conducting auctions for new license plates, selling them to the highest bidder. These plates fetch an average price of $14,230, which is more than China’s per capita GDP and significantly higher than the value of most cars they are meant for. Therefore, purchasing a car in Shanghai can be quite challenging unless you possess substantial financial resources, influential connections, or incredible luck.
“Odd-Even” or “Alternate Day” Driving
odd even or alternate day driving in China
1. Based on the last digit of the vehicle’s registration number: The policy divides vehicles into two groups based on the last digit of their registration number. For example, vehicles with odd-numbered plates may be allowed to drive on certain days, while vehicles with even-numbered plates may be permitted on alternate days.
2. This alternation helps reduce traffic congestion and air pollution by decreasing the number of vehicles on the road each day.
3. The driving restriction policy may have exemptions for certain vehicle types, such as public transportation, emergency vehicles, or vehicles with specific permits. Additionally, the policy may vary across cities or regions, with different schedules and regulations in place.
Monitoring Of Air Pollution Guidelines
monitoring of the rules and regulations in place
Local authorities monitor and enforce the driving restriction policy through various means, including traffic cameras, police checks, and penalties for non-compliance. Violators may face fines or other consequences to ensure compliance with the policy. For example, rule breakers get three points on their license, 12 of which suspends their ability to drive.
By implementing this policy, China encourages the use of alternative transportation methods, such as public transit or carpooling, on designated driving-restricted days.
2. Implementation of Strict Emission Standards Of Air Pollution:
Emission standards for industries, vehicles, and power plants
There are three common types of coal plants — subcritical, supercritical, and ultra-supercritical.
The first being low-temperature and less efficient, the last being high-temperature and more efficient.
subcritical, supercritical, and ultra-supercritical plants
Over time, China has been building fewer and fewer subcritical plants, and more and more efficient ones, thus reducing coal consumption and eventually lowering air pollution.
3. Reduction of coal consumption For Air Pollution:
China focused on decreasing its reliance on coal, a major contributor to air pollution. They implemented policies to promote cleaner energy sources and transitioned from coal to natural gas and renewables.
4. Introduction of cleaner technologies:
electric cars sell in China
China encouraged the adoption of cleaner technologies in various sectors, including industry, transportation, and power generation. This included the promotion of electric vehicles and the development of renewable energy sources. So it’s no surprise that China buys more electric vehicles than the rest of the world combined.
5. Expansion of public transportation:
China invested heavily in expanding its public transportation infrastructure, such as metro systems and high-speed railways. This aimed to reduce the number of private vehicles on the road and subsequently lower pollution levels.
6. Improvement of industrial emissions:
The Chinese government introduced measures to improve industrial emissions by upgrading pollution control technologies and enforcing stricter monitoring.
7. Adoption of renewable energy:
windmill turbine
China made significant efforts to increase the use of renewable energy sources like solar and wind power. They invested in renewable energy projects, developed large-scale solar and wind farms, and incentivized the adoption of clean energy technologies.
8. Implementation of pollution control measures in key industries:
China targeted key polluting industries, such as steel and cement production, and implemented strict pollution control measures to reduce emissions and improve air quality.
9. Strengthening of environmental enforcement:
The Chinese government improved environmental enforcement mechanisms, including increased monitoring, stricter penalties for non-compliance, and enhanced supervision to ensure industries and entities adhered to pollution control regulations.

10. Public awareness and education campaigns:
China launched extensive public awareness campaigns to educate its citizens about the importance of reducing pollution and adopting sustainable practices. These campaigns focused on promoting individual responsibility and encouraging lifestyle changes.
These ten steps illustrate the comprehensive approach that China took to curb its air pollution crisis, leading to significant improvements in air quality over time.
Friends in myprevious article we learn that as a result of air pollution, we breathe various air toxics knowingly or unknowingly almost every day. In this part, we will dive further into their sources and their effect on human health.
Youtube video on Sources Of Air pollution And Its Effects On Human Health
Sources That Pollute Our Air
A) AUTOMOBILES:
In the late 1960s and early 1970s, concerns about air pollution caused by automobiles were growing. Vehicle emissions, particularly nitrogen oxides (NOx), carbon monoxide (CO), hydrocarbons (HC), and particulate matter(PM), were identified as major contributors to air pollution and its detrimental effects on human health and the environment.
sources of co2 emission for a typical household
In response to these concerns, engineers and scientists developed the catalytic converter — a device designed to reduce harmful emissions from vehicles. The catalytic converter works by using catalysts, typically composed of platinum, palladium, and rhodium, to facilitate chemical reactions that convert toxic pollutants into less harmful substances.
“[h]ighway vehicles release about 1.7 billion tons (1.5 billion metric tons) of greenhouse gases (GHGs) into the atmosphere each year — mostly in the form of carbon dioxide (CO2) — contributing to global climate change. Each gallon of gasoline you burn creates 20 pounds (9 kilograms) of GHG. That’s roughly 6 to 9 tons (5 to 8 metric tons) of GHG each year for a typical vehicle.”
When exposed to intense sunlight, certain hydrocarbons, and nitrogen oxides can undergo chemical reactions in the atmosphere, transforming into “photochemical” pollutants with oxidizing properties.
(B) INDUSTRIES :
Industries have consistently taken center stage in discussions concerning the origins of air pollution.
Memorial to those killed and disabled at Bhopal by Dutch Holocaust survivor Ruth Waterman-Kupferschmidt
On the night of December 2, 1984, a catastrophic incident occurred at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal. Due to a combination of factors including inadequate safety measures, human error, and equipment malfunction, a highly toxic gas called methyl isocyanate (MIC) was released into the surrounding atmosphere.
The combustion of fuels for heat and power generation results in the emission of smoke, sulfur dioxide, nitrogen oxides, and fly ash. Petrochemical industries contribute to air pollution by releasing hydrogen fluoride, hydrochloric acid, and organic halides. Additionally, many industries discharge pollutants such as carbon monoxide, carbon dioxide, ozone, hydrogen sulfide, and sulfur dioxide.
(C) DOMESTIC SOURCES
When we talk about where air pollution comes from, we also need to consider domestic sources. Domestic sources of air pollution refer to activities that happen in and around our homes. These can include burning wood or fossil fuels for heating, cooking, or lighting, using certain chemicals or cleaning products that release pollutants into the air, and even smoking tobacco.
Knowing household sources of Air pollution helps us to contribute to reducing such sources as much as possible.
(D) PASSIVE SMOKING
passive smoking
The most direct and important source of air pollution affecting the health of many people is tobacco smoke. Even those who do not smoke may inhale the smoke produced by others (“passive smoking”).
(E) MISCELLANEOUS
These comprise burning refuse, incinerators, pesticide spraying, natural sources (e.g., wind-borne dust, fungi, molds, bacteria), and nuclear energy programs.
burning refuse stubble burning
In agricultural areas of developing countries, there are around 3 million people passed through the horrible experience of pesticide poisoning every year. In India alone, it is believed to cause at least 22,000 deaths annually. Serious illness and even deaths are not uncommon in the state of Kerala where significant numbers of people are exposed to a toxic pesticide called endosulfan. Shockingly, the use of this pesticide continued for 15 years after the tragic events of Bhopal.

examples of primary air pollutants
Primary pollutants are pollutants that are emitted directly into the atmosphere from a specific source, such as a factory, power plant, or vehicle.
Examples of primary pollutants are
Carbon Monoxide (CO)
Carbon monoxide is a colorless and odorless gas produced by the incomplete combustion of fossil fuels. It is primarily emitted from vehicle exhaust and can be harmful when inhaled in high concentrations. Carbon monoxide reduces the oxygen-carrying capacity of blood and can cause headaches, dizziness, and even death.
Sulfur dioxide (SO2)
Sulfur dioxide is a gas produced when fossil fuels containing sulfur are burned, particularly in power plants and industrial facilities. It is a major contributor to acid rain formation and can cause respiratory problems when inhaled in high concentrations.
Nitrogen oxides (NOx)
Nitrogen oxides are a group of gases containing nitrogen and oxygen atoms. They are primarily produced by the combustion of fossil fuels in vehicles, power plants, and industrial processes. Nitrogen oxides contribute to the formation of smog, acid rain, and the depletion of the ozone layer.
Particulate matter (PM)
Particulate matter refers to tiny particles suspended in the air, which can be solid or liquid in nature. These particles can vary in size and composition. Fine particulate matter, known as PM2.5, has a diameter of 2.5 micrometers or less and can penetrate deep into the respiratory system, causing respiratory problems and cardiovascular issues.
Volatile organic compounds (VOCs)
Primary air pollutants sources
Volatile organic compounds are organic chemicals that easily vaporize at room temperature. They are emitted from various sources such as solvents, paints, cleaning products, and industrial processes. VOCs can have adverse health effects and contribute to the formation of ground-level ozone, a major component of smog.
Lead
Lead – a toxic metal that was once widely used in gasoline and other products, but has been largely phased out due to health concerns.
Secondary Air Pollutants
Secondary pollutants are pollutants that are formed in the atmosphere through chemical reactions between primary pollutants and other substances, such as sunlight and atmospheric gases.
These pollutants can be just as harmful as primary pollutants and are often more difficult to control.
EXAMPLES OF SECONDARY POLLUTANTS
Ozone (O3)
Ozone is a gas that occurs naturally in the Earth’s upper atmosphere, forming the ozone layer. However, at ground level, it is a harmful pollutant and a key component of smog. Ground-level ozone is formed when nitrogen oxides and volatile organic compounds react in the presence of sunlight. It can cause respiratory issues and worsen existing respiratory conditions.
Sulfuric acid (H2SO4)
Sulfuric acid is a compound formed through the reaction of sulfur dioxide with water vapor in the atmosphere.
Nitric acid (HNO3)
Nitric acid is a compound formed through the reaction of nitrogen dioxide with water vapor in the atmosphere.
Particulate matter (PM)
Particulate matter can also be formed through the reaction of primary pollutants with other substances in the atmosphere.
There are a group of six air pollutants that are regulated by the United States Environmental Protection Agency (EPA) under the Clean Air Act.
Carbon monoxide, Sulfur dioxide, Nitrogen oxides, Particulate matter, Ozone, and Lead – are considered to be among the most harmful to human health and the environment, and are monitored to ensure compliance with air quality standards.
Based on the chemical composition of air pollutants it can be classified as
Particulate and non-particulate pollutants
Particulate Air Pollutants:
Dust, Lead, smoke, soot, etc. are tiny particles of solid or liquid matter that can be inhaled and can cause serious health problems.
What is particulate?
Particulates, also known as Suspended Particulate Matter (SPM) are tiny particles of solid or liquid matter that are suspended in the air.
Relative comparison of PM with human hair
Suspended Particulate Matter (SPM)
SPM includes particles of different sizes, ranging from coarse particles (between 2.5 and 10 micrometers in diameter) to fine particles less than 2.5 micrometers in diameter known as PM2.5.
Sources of SPM include natural sources such as dust storms and volcanic eruptions, as well as human-made sources such as vehicle emissions, industrial processes, and construction and demolition activities.
(Please note – 1 µm is one-millionth of a meter = 1 micron = 0.001 mm)
Exposure to SPM can have serious negative effects on human health, particularly on the respiratory and cardiovascular systems. SPM can cause or worsen respiratory and cardiovascular diseases, including asthma, lung cancer, and heart disease. It can also contribute to reduced visibility, acid rain, and harm to crops and ecosystems.
Non-Particulate Air Pollutants:
Non-particulate pollutants include
a. Gaseous pollutants:
These are pollutants that exist in the gaseous state at room temperature like so2 co, and can be inhaled directly.
b. Biological pollutants:
These are pollutants that originate from living organisms, such as mold, bacteria, and viruses.
c. Radionuclides:
These are pollutants that emit ionizing radiation and can be harmful to human health.
Now we will discuss the chemicals present in the air that can cause serious health problems.
Hazardous Air Pollutants (HAPs) Or Air Toxics
air-toxics or Hazardous air pollutants(HAPs)
Hazardous air pollutants (HAPs) also known as Air Toxics are a group of chemicals that are known or suspected to cause cancer and other serious health effects. There are 187 plus such pollutants identified by The United States Environmental Protection Agency.
These chemicals can be released into the air by a variety of sources, including factories, power plants, vehicles, and other industrial processes.
The most common hazardous air pollutants (HAPs) emitted into the air can vary depending on the location and sources of emissions. However, some of the most common examples of HAPs include:
1. Benzene: Benzene is a carcinogenic chemical that is commonly found in gasoline and is also emitted from industrial sources such as oil refineries and chemical plants.
2. Formaldehyde: Formaldehyde is a colorless gas that is used in the manufacture of many consumer products and is also emitted from industrial sources.
3. Mercury: Mercury is a neurotoxic metal that is emitted from coal-fired power plants and other industrial sources.
4. Polycyclic Aromatic Hydrocarbons (PAHs): PAHs are a group of chemicals that are produced during the combustion of fossil fuels and other organic matter. They are found in vehicle exhaust and in emissions from industrial processes such as coke ovens and asphalt production.
5. Lead: Lead is a toxic metal that was once widely used in gasoline and other products. It is emitted from industrial sources such as lead smelters and battery manufacturing plants.
6. Chlorine: Chlorine is a toxic gas that is used in the manufacture of many consumer products and is also emitted from industrial sources such as chemical plants.
7. Asbestos: Asbestos is a naturally occurring mineral that was once widely used in insulation and other building materials. It is a carcinogenic substance that can be released into the air during demolition or renovation of buildings.
Depending on the scale at which air pollution is happening it can also be divided into local, urban, regional, and global air pollution.
Local Air Pollution:
Some pollutants, by virtue of their source or of having a very short atmospheric lifetime, are only encountered in appreciable concentrations close to where they are emitted.
poorly controlled household and neighborhood sources, often involving the burning of biomass fuels, stubble cause serious local pollution mostly in less developed countries.
Urban Scale Air Pollution:
Pollutants originating from urban sources, like nitrogen oxides and carbon monoxide emitted by vehicles, are usually found in high concentrations within cities but decrease significantly in nearby rural areas. These pollutants have relatively short atmospheric lifetimes, typically lasting only a few hours. As a result, their concentrations in the distant background atmosphere are usually very low, except for carbon monoxide, which persists for a longer duration.
Regional Scale Air Pollution
Fine particles, typically less than 2.5 µm in diameter (excluding ultrafine particles), along with certain gaseous pollutants like ozone, have atmospheric lifetimes ranging from days to weeks. This extended lifespan allows them to be transported over regional distances. Pollutants such as sulfate particles and ozone can travel thousands of kilometers through a process called long-range transport, even crossing national borders in the process.
Hemispheric Or Global Scale Air Pollution:
Certain pollutants, particularly those linked to greenhouse warming effects such as carbon dioxide, nitrous oxide, and methane, have long atmospheric lifetimes spanning years. As a result, they can disperse across an entire hemisphere and eventually become distributed globally. These pollutants have the potential to contribute to climate change on a global scale due to their extended presence in the atmosphere.
Air pollution as per the location of the source of pollution can affect human health as Indoor Air pollution and outdoor air pollution.
Indoor Air Pollution:
Indoor air pollution refers to the presence of air pollutants inside buildings, homes, and other enclosed spaces. Sources of indoor air pollution include tobacco smoke, cooking and heating appliances, building materials, household cleaners, and chemicals used for pest control.
Outdoor Air Pollution:
Outdoor air pollution refers to the presence of air pollutants in the outdoor environment, such as in the air we breathe outside. Sources of outdoor air pollution include emissions from vehicles, power plants, factories, wildfires, and other sources.
Air pollution refers to the presence of harmful substances in the air that can negatively impact the environment and human health. When we talk about air pollution, we are referring to the contamination of the air we breathe with various pollutants.
These pollutants can come from both natural and human-made sources. Natural sources include volcanic eruptions, dust storms, and wildfires, while human-made sources include industrial emissions, vehicle exhaust, the burning of fossil fuels, and the release of chemicals and pollutants from factories and power plants.
The pollutants in the air can take different forms, such as gases, particles, or toxic chemicals. Common air pollutants include carbon monoxide, nitrogen dioxide, sulfur dioxide, ozone, particulate matter, and volatile organic compounds.
Air pollution has significant consequences for the environment and human health. It can contribute to climate change, damage ecosystems, harm wildlife, and reduce agricultural productivity. When it comes to human health, air pollution can cause respiratory problems, cardiovascular diseases, allergies, and even lead to an increased risk of certain cancers.
