Summary

Every year, millions of people are killed by air pollution. We require sustainable and lucrative solutions! The Solar Wind Project is investigating novel ways to tackle air pollution.

The answer to air pollution is to transition away from fossil fuels and toward alternative energy such as solar, and geothermal. It is critical to generate renewable energy. However, it is equally necessary to limit our energy use by adopting responsible practises and utilising more energy-efficient gadgets.

Frequently Asked Question

People usually ask many questions about Types of Air Pollution. A few of them are discussed below:

1 How does air pollution occur?

Pollution reaches the Earth’s atmosphere through a variety of pathways. The majority of air pollution is caused by humans, form of emissions from industries, vehicles, or aerosol cans.

Types of air pollution - includes primary air pollution and secondary air pollution. These types are based on the types of pollutant. Air or atmospheric pollution can be defined as the result of the discharge into the atmosphere of large amounts of particles, solid or liquid, that have the potential to cause environmental impacts or harm to human health.

Among these substances, we can mention dust from industries, aerosols, black smoke, solvents, acids, and hydrocarbons.

Types of air pollution

Air pollution is a generic name we use for a wide range of substances. Pollutants can be classified into two types: primary pollutants and secondary pollutants.

Primary Pollutants:

Primary pollutants are those released directly into the atmosphere from anthropogenic and natural sources. Secondary pollutants are products of chemical and photochemical reactions, which occur in the atmosphere involving the primary pollutants. Let’s get to know the main air pollutants :

1. Carbon Monoxide (CO)

A colorless, odorless and toxic gas. Mainly produced by incomplete burning of fuel. It interferes with the transport of oxygen in our body and can cause suffocation.

2. Carbon Dioxide (CO2)

It is a fundamental substance for living beings. Vegetables use carbon dioxide to carry out their photosynthesis, a process in which they use solar energy and CO2 to produce energy.
The gas is produced in the process of cellular respiration, but it has other sources, which are the cause of much of the air pollution, such as the decomposition process and the burning of fossil fuels.

This gas is currently well known for being one of the causes of the greenhouse effect. This is due to the fact that CO2 absorbs part of the radiation emitted by the Earth’s surface, trapping heat, resulting in an increase in temperature.

3. Chlorofluorocarbons (CFCs)

They used to be emitted from products such as air conditioners, refrigerators, aerosol sprays, among others. These compounds are currently banned throughout most of the world.

When in contact with other gases, CFCs damage the ozone layer, is largely responsible for its hole, thus allowing ultraviolet rays to reach the Earth’s surface, causing problems such as skin cancer.

4. Sulfur Oxides (SOx)

The most harmful is sulfur dioxide, which is produced in various industrial processes and by volcanic activities. In the atmosphere, sulfur dioxide forms sulfurous acid, causing acid rain.

5. Nitrogen Oxides (NOx)

Nitrogen dioxide (NO2) in particular is a major factor in air pollution. These oxides are highly reactive gases, formed during combustion by microbiological action or by lightning. In the atmosphere, NOx reacts with volatile organic compounds and carbon monoxide to produce tropospheric ozone. It is also oxidized to nitric acid, which contributes to acid rain.

6. Volatile Organic Compounds (VOCs)

These elements that makeup air pollution are organic chemicals emitted from various sources, including fossil fuel burning, industrial activities, and natural emissions from vegetation and fires.

Some VOCs (or VOCs) of anthropogenic origin, such as benzene, are carcinogenic pollutants. Methane is a volatile organic compound that contributes to the greenhouse effect and is approximately 21 times more potent than carbon monoxide.

7. Ammonia (NH3)

Mainly issued by agriculture due to the use of fertilizers. In the atmosphere, ammonia is a type of air pollution that reacts to form secondary pollutants.

8. Particulate Material (PM)

They are fine particles of suspended solids or liquids. This material occurs naturally from volcanic eruptions, sandstorms, fog formation, and other natural processes. Human action produces PM in industrial activities, mining, and combustion of fossil fuels, among others. In the atmosphere, this material is harmful to health.

The smaller the particle, the greater the effects caused. Some effects caused by the particulate matter are respiratory and heart problems.

9. Tropospheric Ozone (O3)

Despite being extremely necessary for the atmosphere to block solar radiation, the ozone that is formed in the troposphere (closer to the Earth’s surface), from reactions with other pollutants, is a form of air pollution that causes several damages to our health, such as irritation and respiratory problems.

Causes of air pollution

There are several activities and factors that are causes of air pollution. These fonts can be divided into two categories:

Natural sources

• Dust from natural sources, such as from desert areas;

• Methane emitted in the digestion process of animals. This emission is increased by human activity due to the large number of animals raised for food, such as cattle, for example, which corresponds to a large part of methane emissions into the environment;

• Smoke and carbon monoxide emitted by natural fires;

• Volcanic activity, which emits various pollutants such as carbon dioxide, sulfur dioxide, and ash in large quantities, which can cause terrible damage;

• Microbiological activity in the oceans, releasing sulfur gases;

• Radioactive decay of minerals (rocks);

• Plant emissions of volatile organic compounds (VOCs);

• Organic matter decomposition.

Anthropogenic sources (caused by humanity)

• Factories, power plants, incinerators, furnaces, and other stationary sources. Locations that burn fossil fuels or biomass, such as wood;

• Automotive vehicles such as cars, motorcycles, trucks, and planes. Transport contributes about half of the carbon monoxide and nitrogen oxide emissions;

• Controlled fires in agriculture and forest management. In Brazil, this practice is responsible for about 75% of carbon dioxide emissions;

• Aerosols, paint, sprays hair and other solvents;

• Decomposition of organic waste, which generates methane;

• Ammonia emission from the use of fertilizers;

• Mining activity.

Where does air pollution occur?

These emissions have five basic sources produced by humans:

Industries

• In many countries, energy production is the main source of air pollution, although not the only one.

The burning of coal by power plants or those plants based on diesel are two of the most frequent and harmful emission sources. In the same way, although to a lesser extent compared to the previous ones, industrial processes and the use of solvents in chemical industries contribute to air pollution and global warming.

• Faced with this problem, industries are globally incentivized through international policies and programs to make efficient use of energy and invest in renewable energy sources. This helps industrial activities to achieve cleaner energy production, greater energy efficiency, and a reduction in the effects of air pollution.

Transport

• About 25% of all energy-related CO2 (carbon dioxide) emissions come from transportation. These emissions cause approximately 400,000 pre-mature deaths per year from poor air quality.

Half of them are a consequence of the emission of diesel due to the emission of nitrogen oxides. There is no doubt that current transport is inefficient, expensive and unsustainable as it cannot keep up without compromising future generations.

• In Spain alone, pollution has caused the death of nearly 100,000 people in the last decade. And, according to United Nations data, car causes 13% of air pollution in the member countries of the European Union.

The sovereignty of the car in front of other more sustainable means is a pending task for all.

• In urban areas with large concentrations of populations, it is essential to work on policies that contribute to the reduction of air pollution. For example, through the use of cleaner fuels or the implementation of means of transport powered by renewable energies that are not harmful to people.

Farming

• In this sector, there are two main sources that produce 24% of all greenhouse gases. On the one hand, the burning of agricultural waste and, on the other, the methane and ammonia generated by livestock.

Methane emissions are especially notable since they affect ozone at ground level.

• This air pollution causes respiratory diseases and increases asthma. Methane is also a greenhouse gas (although this idea is not always reinforced) that has a greater impact than CO2 in the long term (for example, in periods of 100 years).

• To reduce this pollution from the agricultural sector, the people who work in it can carry out a reduction of methane by optimizing the digestibility of food, improving grazing, and with more adequate and sustainable management of pastures. But the consumer is also an important part of reducing these emissions.

For example, by reducing meat consumption or minimizing food waste, thus avoiding overproduction based on a large demand for food.

Waste

• It is estimated that 40% of the waste generated in the world and organic waste is burned in the open air, which generates emissions into the atmosphere of harmful dioxins, furans, methane, and black carbon.

A problem that especially affects those regions or areas that are in the process of urbanization or developing countries.

• Among the strategies to avoid the effects of this type of air pollution is the improvement in the collection, separation, and disposal of solid waste. This could reduce the number of materials deposited in landfills and subsequently burned in the open air.

• As in the agricultural sector, less food waste would help reduce the amount of organic waste that must be managed.

In the same way, separation of these and their conversion into compost or bioenergy would help to improve the fertility and quality of the soil, also generating a way to create an alternative, cleaner, and more sustainable source of energy for the air.

Households

• Air pollution from the home is harmful in two ways. On the one hand, because it is the air that people breathe in their homes directly, causing respiratory diseases in the medium and long term; on the other hand, because it affects the outside air.

The source of this pollution comes from the burning of wood and fossil fuels for activities such as cooking, heating, or lighting homes.

• Maintaining the quality of the air is essential for the survival of the people and species that live on Earth. The effects of air pollution can be fatal for species, since pollution negatively affects their health, promoting the development of diseases and conditions of different types, such as respiratory disease.

As always, there are a number of tips that we can follow that can have a great impact on protecting the quality of the air we breathe.

Summary:
Although in general terms, 85% of households have access to cleaner energy sources, in at least 97 countries of the world, the truth is that it is estimated that approximately 3,000 million people continue to use solid fuels, which is a figure very high that produces a large amount of polluting emissions into the air.

Sources of pollution

Air pollution is a complex, constantly evolving mixture of pollutants which can be:

Chemicals, such as ozone, nitrogen dioxide, and oxides, sulfur dioxide, metals (lead), certain volatile organic compounds (VOCs) such as butane, ethanol, or benzene, or also hydrocarbons (polycyclic aromatic hydrocarbons - PAHs) present in coal, petroleum, or resulting from the combustion of fuels or wood;

Physical, such as fine particles, dust made up of a multitude of chemical components;

Organic , such as pollens an

A small amount of these air pollutants come from natural phenomena (sand winds from the Sahara, soil erosion, volcanic eruptions, etc.) and mostly from human activities.

Effects of pollutants on health

Pollutants	Main health risks
Ammonia	> Exposure to very high concentrations causes irritation and even burns to the eyes and respiratory system
Sulphur dioxide	> Respiratory tract irritation (cough, respiratory discomfort, asthma)
Hydrocarbons and volatile compounds	> Irritations, breathing difficulties, frequent odor nuisance
> Benzene is classified as carcinogenic to humans
Nitrogen oxides	> In the short term, irritations and worsening of respiratory diseases (asthma)
> In the long term, development of respiratory or cardiovascular diseases, low weight of the infant, and increased risk of death
Ozone	> Breathing discomfort, cough, eye irritation, asthma attacks, the onset of respiratory diseases
Particles or particulate matter	> In the long term, development of cancers (lung, bladder), cardiovascular and respiratory diseases, impairment of the neurological development of the child, diabetes, etc.

Effects of air pollution

The air pollution can cause a huge impact on two major areas: human health and the environment. Among the main effects of air pollution are respiratory diseases and environmental problems.

Effects of air pollution on human health

• Irritation in the throat, nose, and eyes;

• Breathing difficulties;

• Cough;

• Development of respiratory problems;

• Worsening of heart or respiratory problems such as asthma;

• Decrease in lung capacity;

• Increased chance of heart attacks;

• Development of different types of cancer;

• Damage to the immune system;

• Damage to the reproductive system.

In the latter case, damage involving the reproductive system can even include infertility. A study published in Environment International looked at more than 18,000 couples in China and found that those exposed to moderately higher levels of pollution had a 20% higher risk of infertility.

According to scientists, pollution particles are known to cause inflammation in the body, which can impair the production of eggs and sperm.

Another study of 600 women attending an infertility clinic in the United States found that increased exposure to air pollution was associated with fewer maturing eggs in the ovaries.

Other research has also shown that polluted air can pose reproductive risks, including pre-mature birth and low birth weight. According to scientists, when it comes to miscarriage, common levels of nitrogen dioxide are as bad as smoking.

Finally, one study found that women who were exposed to higher levels of air pollution had an increased risk of brain changes linked to Alzheimer’s disease over five years.

Effects of air pollution on Environment

The impacts on the environment depend on the type of air pollution and arrive on a global scale. Among the main effects of air pollution on the environment, the following stand out:

1. Acid rain

Causes the acidification of the atmosphere. In water bodies it provides water acidification, causing the death of fish, and in soils, it causes the modification of its physicochemical properties. In forests, trees are damaged by acid rain, as are buildings and structures in the city that can corrode.

For these reasons, several countries have started to take actions to reduce the effects of acid precipitation, such as a reduction in the amount of sulfur present in fuels.

2. Decrease in the ozone layer

Stratospheric ozone forms a layer that protects life on Earth from the emission of ultraviolet rays.

However, with their destruction due to chemicals released into the atmosphere by humanity, these rays manage to cross the layer, which causes an increase in the amount of UV radiation, increasing, in humans, the risk of developing skin cancer and other problems.
Ultraviolet rays also harm agriculture, because some plants, such as soybeans, are sensitive to this type of radiation.

3. Atmosphere darkening

With air pollution, clarity and visibility are diminished. This effect interferes with the water evaporation process because the formed clouds absorb the heat emitted by the sun, a fact that can mask global warming.

4. Greenhouse effect

The greenhouse effect itself is a fundamental process for life on Earth, as it makes the planet stay warm.

But there are theorists who argue that the significant increase in greenhouse gases emissions, associated with other actions also promoted by human activity, such as the deforestation of forests, are decisive in the unbalance of the process, generating greater energy retention and an increase in the effect.

Greenhouse, with the warming of the lower atmosphere and an increase in the planet’s average temperature, and possible environmental distortions. Global warming has become one of the Earth’s biggest problems, with effects that could be catastrophic.

5. Eutrophication

The various types of air pollution end up being deposited in water bodies by precipitation, causing a change in the nutrients present in these systems. Some algae can be stimulated in the presence of pollutants such as nitrogen, which causes their development and a consequent decrease in the amount of dissolved oxygen in the water, leading to fish death.

Effects on animals

Like humans, animals suffer from health problems caused by air pollution.

Air Quality Index

• The Air Quality Index defines the maximum limit for the concentration of a certain pollutant in the atmosphere. This concentration limit is a standardized value, which varies according to the agency or entity that defines it.

• Its purpose is to inform the population about the air quality in a given region in an accessible language. Measurements are made at monitoring stations that measure the concentration of pollutants, especially the concentration of ozone and particles at ground level.

• It is usually made available in real-time at the monitoring station by the agency that takes care of its measurement in the region. In Brazil, the standards were established by the Brazilian Institute for the Environment and Renewable Natural Resources (Ibama) and approved by the National Environment Council (Conama), through Conama resolution 03/90.

• A study has shown that the amount of pollution that comes into the home depends on the type of pollution outside. Therefore, forest fires, fireworks, and thermal inversion affect the indoor air to different degrees. Therefore, it can be concluded that the Outdoor Air Quality Index depends on several factors and is not the same as indoors.

How to reduce air pollution?

The reduction of air pollution is an urgent demand that needs to be debated by all nations. Some local and individual actions can be taken always thinking that, if everyone contributes in the same way, it is possible to drastically reduce the levels of pollutants in the atmosphere.

Some actions that can be taken are:

• whenever possible, do not use the car. Move by public or alternative transport;

• turn off appliances that don’t need a constant [power source, such as TV, computer, and lights;

• recycle household waste;

• prioritize companies with a green seal, which carry out actions of environmental responsibility.

Everything we consume or do leaves a trail on the planet. That’s why we’ve put together some simple tips to reduce your footprint on air pollution :

• Try not to use your car to get around. Going to work by public transport or using an alternative means of transport, such as the bicycle, are actions that greatly reduce your contribution to the emission of pollutants;

• Turn off lights, TV, and computer when you leave the house. Save energy, as its production contributes to global warming;

• Consume locally produced products, this will greatly reduce pollutant emissions from product transport;

• Try to recycle your household waste, thus reducing the consumption of energy and raw materials needed to manufacture new products. Check the recycling points closest to your home;

• Choose products from environmentally responsible companies.

How does air pollution spread and how can we deal with it?

• The dispersion of air pollutants depends mainly on the physical processes in the air; those of wind and weather.

The distance over which air pollutants are transported depends on the particle size of the compounds and how high the pollutants were emitted into the air. The vapors emitted in the air will mix in the air so, locally, the concentrations will not be very high.

• However, the wind will carry the compounds and the pollution will be widely dispersed. Rain can remove pollutants from the air. They are carried away by precipitation and thus can contaminate soil and water.

• For environmental agencies, it is very important to determine exactly how pollutants in the air are spread. Air is not a very complete environment.

This allows us to predict the dispersion of air pollutants with computer models. By computer, the dispersion is calculated using various parameters such as wind speed, wind direction, temperature, air humidity and cloudiness.

• These predictions are of great importance when dealing with toxic clouds or radioactive radiation, because they are dangerous for human health and the inhabitants of these polluted areas must be warned.

Frequently Asked Questions:

Here are some frequently asked questions regarding air pollution.

1. How are air pollution and climate change connected?

Air pollution and climate change are inherently linked. All major air pollutants have an impact on the climate and most share common sources with greenhouse gases (GHGs), especially related to the combustion of fossil fuels. They also aggravate each other in multiple ways.

For example, GHGs, such as methane, contribute to the formation of ground-level ozone, and levels of ground-level ozone increase with rising temperatures. Rising temperatures increase the frequency of wildfires, which in turn further elevate levels of particulate air pollution.

2. What actions can the government take to improve air quality?

• Governments are responsible for providing their citizens with clean air. There are multiple options for national and local governments to improve air quality. Air pollution is a problem that we know how to solve.

• Governments need to invest in the capacity to measure and monitor air pollution by establishing monitoring networks, and ensuring that such networks are properly operated, maintained, and subjected to procedures that guarantee the quality and reliability of air quality measurements.

The first step towards responsible management of air pollution is to make sure that necessary regulations, policies, and enforcement mechanisms are in place and sufficiently supported. Governments should ensure that the appropriate institutions have sufficient capacity to monitor and assess air pollution emissions.

• This will ensure that decision-makers know where their air pollution comes from, how large the different sources of emissions are, the levels of air pollution in different parts of their country, the impacts on health, and what high impact actions can be taken to reduce pollution levels and reduce the harm caused.

3. What can an individual do to improve air quality in her community?

Some of the things individuals can do to reduce their personal contribution to air pollution are:

• choose clean modes of transport when available (e.g. public transport, cycling or walking rather than private cars or motorbikes);

• if you’re considering buying a car, look at its nitrogen dioxide emissions and check the real-world emissions for that car. Avoid buying diesel cars. Buying a hybrid or electric vehicle will also help to cut down your emissions;

• if you have a car, ensure it is serviced regularly to minimize its contribution to air pollution;

• use clean fuels and technologies for cooking, lighting, and heating;

• use renewable energy sources wherever possible;

• stop burning household and agricultural waste;

• eliminate fireplace and wood stove use;

• monitor your energy demand and waste at home and install energy-efficient appliances and light bulbs, insulation and draught-proof windows.

4. How do wildfires contribute to air pollution?

• Smoke from wildfires as well as other landscape fires used for land clearing and agriculture is a major contributor to air pollution, contributing to roughly 4% of global PM2.5 but responsible for 10 – 60% in many countries of the world.

• Extreme fire smoke events can lead to very high levels of air pollution over 1-2 weeks periods, easily the highest levels experienced throughout the year in affected locations. Prominent examples are Australian bushfires, land clearing, and peat fires in Indonesia, as well as wildfires in Canada, Russia, and in the western US.

• In the western US, it is estimated that approximately 46 million people were exposed to at least one wildfire smoke event during 2004-2009.

Wildfire smoke clearly leads to a worsening of pre-existing respiratory diseases, such as asthma and chronic obstructive pulmonary disease (COPD), with emerging evidence of impacts on cardiovascular disease, increased complications for those with type 2 diabetes as well as links between in utero exposure and low birthweight babies.

• It is not yet known whether discrete smoke episodes that are experienced year after year have cumulative impacts, although evidence from air pollution, in general, suggests this is also likely.

From the perspective of overall, population-level impacts, an analysis conducted in 2012, estimated that smoke from landscape fires accounted for approximately 10% of the estimated annual deaths attributable to particulate matter air pollution.

5. Is acid rain air pollution?

Aerosols and photochemical oxidants (e.g. ozone) can also create haze and reduce visibility, which can shroud cities in dense smog.

Falling concentrations in North America and Europe have reduced this haze significantly, but it is very prevalent in other parts of the world, especially in Asia**.

The strong link between visibility and pollution was illustrated when people in parts of Northern India could see the Himalayas for the first time in a generation when air pollution levels fell due to the lock-down and reduced emissions, caused by the COVID-19 crisis.

6. For how long has air pollution been a problem?

Air pollution has been associated with humans for millennia, starting with the use of fire for cooking and warmth. Dangerously high levels of outdoor air pollution became a problem during the industrial revolution, where the massive use of coal gave rise to many episodes of serious urban air pollution.

7. Why is it important to solve air pollution?

Air pollution is all around us. Most people in the world live in areas with high levels of air pollution. It harms human health and wellbeing, reduces the quality of life, and can negatively impact the economy. These impacts also disproportionately affect the most vulnerable people and communities.

Air pollution is the largest environmental risk to public health globally. People everywhere are exposed to air pollution, in the workplace, during travel, and in their homes. Exposure to household and ambient (outdoor) fine particulate matter air pollution causes an estimated 7 million pre-mature deaths each year.

According to the World Health Organisation (WHO), and is responsible for a substantial amount of disability for those living with diseases caused by air pollution.

8. What is the impact of air pollution on human health?

The air pollutant of greatest concern for human health is fine particulate matter. This has a diameter of 2.5 micrometers or less, also known as PM2.5. These fine particles are invisible to the human eye and 40 times smaller than the width of a human hair. They can do a lot of damage to our bodies.

These particles are small enough to travel deep into our lungs, where they cause inflammation of sensitive lung tissue and can pass into the bloodstream, affecting organs like the heart and brain. The WHO estimates that exposure to PM2.5 causes 7 million pre-mature deaths annually.

Air pollution causes both acute disease and chronic disease. **There is strong evidence linking long-term exposure to air pollution with an increased risk for ischaemic heart disease, stroke, chronic obstructive pulmonary disease (COPD), lung and upper aerodigestive cancers, adverse pregnancy outcomes that are:

(i.e. low-birth rate, pre-term births and reduced birth weight (babies born weighing less than five pounds), diabetes and cataracts.**

9. What effects does ar pollution have on food, crops, forests, and biodiversity?

Ozone (O3) is by far the main air pollutant affecting plant growth. It reduces crop yields, forest health, and biodiversity generally. Different plant species have different sensitivity to O3; those more sensitive to O3 will have a reduced competitive advantage in ecosystems, while more resistant species will become more dominant.

Some crops are very sensitive to O3, especially beans. Soybean yields, for example, can be reduced by 15% or more. There is also a knock-on effect on the climate, as the reduced growth of forest trees caused by O3 pollution, reduces the ability of forests to absorb carbon dioxide and their potential to help regulate climate change.

10. How is air pollution spread?

Air pollutants can be carried by the wind, causing pollution to spread. Rain can remove pollutants from the air, causing soil and water pollution. Sunlight helps transform air pollutants into different substances.

11. What are the main sources of air pollution?

All sectors of human activity are likely to emit atmospheric pollutants: industrial activities, waste treatment, and construction sites, transport (road, air, river), domestic activities (heating in particular), agriculture, or forestry.

12. What are the causes and consequences of air pollution?

The main causes of air pollution are related to the ignition of fossil fuels (coal, oil, and gas). The combustion of these raw materials occurs mainly, during or in the operation of the industrial and land transport sectors.

13. What are the main causes of pollution?

The main pollutants and their main sources.

• Particles (PM10): 15% diesel road transport and wear dust (roads, brakes, tires).
• Volatile Organic Compounds (non-methane VOC): 11%
• 1% road transport (gasoline cars, two-wheelers) and river transport.
• Sulfur dioxide (SO2): 2%.

14. What are the main pollutants and their origins?

Pollutants : their origins

• volcanoes, which send huge amounts of gases and particles into the atmosphere;

• plants that produce pollens, some of which can cause allergies;

• lightning which emits oxides of nitrogen and ozone;

• erosion which produces dust.

15. What creates pollution?

The pollutants found in the atmosphere can be of anthropogenic origin, that is to say produced by human activities or of natural origin (emissions by vegetation, soil erosion, volcanoes, etc. oceans, etc).

Conclusion
Air pollution is one of the greatest problems facing humanity today. With direct impacts to our way of life, it is urgent that we have a change of mindset. Little by little, countries are moving towards an understanding of the preservation of the environment, especially with regard to gaseous emissions into the atmosphere.
