Because of the way people now live, carbon monoxide is produced in great quantities, and one of its biggest disadvantages is the fact that it is odorless, tasteless, and clear.
Particulate matter
Often described as the most damaging air pollutant from a human health perspective, particulate matter (or PM, for short) differs from most of the other pollutants on this list.
Carbon dioxide
There is some debate as to whether greenhouse gases like carbon dioxide (CO2) constitute an air pollutant, since their impact is felt more in the long-term repercussions on the planet than the immediate quality of the air they inhabit.
Carbon monoxide
Unlike CO2, carbon monoxide (or CO) is undoubtedly an air pollutant. In fact, it is regarded as being responsible for the biggest number of fatalities in many parts of the world if humans are exposed to it for many hours at a time.
Ozone
When most people hear the word ozone, they immediately think of the protective layer which surrounds our planet and protects us from the full force of the sun’s rays. This is stratospheric ozone and it is highly beneficial to life on Earth.
Nitrogen dioxide
Nitrogen dioxide (NO2) belongs to the nitrogen oxides (NOx) group of pollutants. It, like nitric oxide (also known as nitrogen monoxide, or NO), is produced primarily through the combustion of fossil fuels.
Sulphur dioxide
Sulphur dioxide (SO2) is formed when any material such as coal, petroleum coke and fuel oil is combusted, since these substances all contain high levels of sulphur.
How is air pollution monitored?
In order to gain greater insight into these various types of air pollution, governments around the globe have begun introducing greater regulation around the monitoring of emissions.
What are the two types of air pollution?
Generally, air pollution has been divided into two types. 1. Indoor pollution. It is the pollution of air caused by the introduction of materials from smoking and burning fossil fuels such as kerosene, petroleum and coal indoors. Fuels are burned indoors for cooking and cooling or heating purposes.
Where does air pollution come from?
The levels of outdoor air pollution reach their peak in developing countries, most of them from Asia. The air outside is polluted mainly from vehicle exhaust and emissions from industries. Several pollutants are mixed in the air and a large portion of the world population is regularly exposed to harmful air quality.
What are the health problems caused by smog?
Smog can cause several health problems like breathing problems, decrease in resistance to colds and infections, irritation of eyes and throat, asthma etc.
Why is particle pollution so bad?
This kind of pollution is caused due to the exhaust from burning diesel fuels in heavy transportation, burning of fuels in power plants and burning wood. It has been known to increase problems of heart diseases, cancer of the lungs, coughs and asthma.
How does air pollution affect wildlife?
Air pollution effects wildlife and plant life. The particulate matter can change soil chemistry and consequently bring changes in the growth of vegetation. Introduction of more gases like nitrogen oxides, sulfur oxides, carbon dioxide etc. also play a role in formation of harmful ozone and acid rain which effects all living organisms.
What is the mixture of smoke and fog?
Smog. Smog is the mixture of two components; smoke and fog. The term was introduced first in mid-20 th century in London. Its primary component is harmful ozone found at ground level. Smog is formed as a result of complex photochemical reactions that involve nitrogen oxides and volatile organic compounds.
Is indoor air pollution worse than outdoor air pollution?
One half of the population in the world or 80% of the population in South Asia and Africa is affected by indoor air pollution from burning of coal and biomass. It is assumed that indoor air pollution is much worse than pollution outdoors. 2. Outdoor pollution.
What is the most known form of air pollution?
The most known form of air pollution is this gas and it is the culprit when it comes to the production of a greenhouse effect. It severely affects the climate of the earth and is one of the things that is hugely responsible for the climatic variations at almost every place on the earth.
What is air pollution?
Basically, air pollution is the presence of pollutants in the air which is further breathed in by us leading to serious harmful diseases. The pollutants come in many forms. They may be liquid droplets, solid materials, etc and many more. Pollutants can be further subdivided into two heads, primary and secondary.
What are the most harmful gases?
There are a number of hydrocarbon VOC’s, which can also be stated to be responsible for polluting the air and making the earth worse. 3-butadiene is one of the most dangerous compounds that can lead to air pollution and is one of the most harmful gases ever.
Why are people dealing with air pollution?
People are now dealing with air pollution on a daily basis due to its massive spread. For a long time, the factories, car engines, etc have been polluting the environment by spreading harmful gasses and for all that, the atmospheric layer has been severely damaged. Save.
How much less CO2 does natural gas emit?
Natural gas emits 50 to 60 percent less carbon dioxide (CO2) when combusted in a new, efficient natural gas power plant as against e missions from a typical new coal plant. Exposure to high levels of these air pollutants will result in adverse health outcomes, including respiratory symptoms, cardiovascular disease, and cancer.
What are the two types of particles in the air?
The particles can generally be divided into types, solid and liquid . The liquid particles are generally made up of ashes which are produced when certain substances are burned such as coal. Diesel exhaust and chemicals in the air are also considered to be a popular source of liquid particle pollution. Most of the passenger vehicles such as the bus can produce massive amounts of pollutant ashes which further lead to air pollution. Burning of wood and other similar substances can lead to particle pollution.

What are the particles in the air?
This group of air pollutants refers to solid particles that appear as a result of mixing the droplets present in the air with soot, dust, and mineral elements. It can have a natural origin – for example, wildfires or volcanic eruptions. However, the majority of particulate matter emissions come from burning processes and have an anthropogenic background.
What is the most common gas in the atmosphere?
SO₂ is one of the most widespread gases polluting the atmosphere, emitted by heating and industrial plants. High concentrations of SO2 negatively affect the respiratory system, damaging the epithelium of the airways (nose, throat, lungs) and causing their narrowing.
What is PM10 in air?
PM10 are air pollutants with a diameter of 10 micrometers (micrometer = one-thousandth of a millimetre) or less. Dust with a diameter of less than 10 micrometers is absorbed in the upper respiratory system and bronchi. When it enters the lungs, it can cause coughing and difficulty with breathing. PM10 contributes to an increased risk of respiratory infections and the occurrence of exacerbations of allergic diseases such as asthma, hay fever, and conjunctivitis.
What is NO2?
NO, or nitric oxide (III), is a colourless gas that behaves as a free radical. In the presence of oxygen, it is oxidized to nitrogen dioxide (NO2). Nitrogen dioxide NO2 damages immune cells in the lungs and causes increased susceptibility to respiratory infections.
