Air Pollutants | no+o2=no2
The chemical reaction you described is the result of the combination of Nitric oxide (NO) with oxygen (O2) to produce nitrogen dioxide (NO2). This reaction is an important pollutant to the air, especially in urban areas.
Nitric oxide (NO) is an inert gas generated during high-temperature combustion processes, such as in a car engine, power plant, or industrial process. NO is then transformed into the atmosphere, usually through reactions with oxygen (O2) which results in the gas nitrogen dioxide (NO2), a reddish-brown-colored gas. Nitrogen dioxide gas is a key part of smog, and it could negatively impact human health and the environment.
Alongside nitrogen dioxide, commonly used air pollutants are sulfur dioxide (SO2) and carbon monoxide (CO), and PM, Particulate Matter (PM), as well as Ozone (O3). These pollutants come from many sources, such as industry, transportation, and power generation.
Exposure to air pollution could have adverse health consequences, including the development of respiratory ailments, cardiovascular diseases, or lung cancer. In addition, air pollution could cause environmental harm by contributing to acid rain, climate change, and the destruction of the ozone layer.
How To Balance:
NO + O 2 – NO 2
Word equation: Nitrogen monoxide + Oxygen gas – Nitrogen dioxide
The type of chemical reaction: For this chemical reaction, we can call it a mixed reaction.
Balancing Strategies: In this mix (known as the synthesis) reaction, O2 and NO combine to create NO2.
Make sure you take note of all the Oxygen Atoms that are on the reactant part of the equation.
In balancing chemical equations, we aim to achieve equal amounts of each kind of atom in both equations.
Simply change these coefficients (these are the numbers that appear in the front of the substances).
Do not alter the subscripts (the tiny numbers that follow elements).
Pollution from the air has been an important environmental problem for many years, and one key component in air pollution is particulate Matter (PM). PM is a complex mix of microscopic particles suspended within the air and can cause harmful impacts on humans and the environment. In this article, we’ll examine PM in air pollutants, its causes impacts, and ways to minimize its impact.
Sources Of Particulate Matter In Air Pollutants
There are various sources for PM in air pollution, which are man-made and natural. Natural sources include sea salt, dust, and wildfires. Human-made sources include transportation, industrial processes, and power generation. Some of the biggest sources of PM in the air pollutants are:
- Transportation – Vehicles traveling on highways and roads emit PM through their brakes and exhaust systems.
- Industries – producing steel, cement, and chemicals can release PM.
- Generation of power – stations that burn fossil fuels produce PM and other power plants that produce electricity.
- Building activities: Dust produced by construction activities like excavation and demolition could cause PM to air pollution.
What Is The Impact Of Particulate Matter Affect Human health?
Exposure to PM may negatively impact the human body’s health, especially the cardiovascular and respiratory systems. Inhaling these small particles can enter deep inside the lungs leading to inflammation and harming the lung’s tissue. This could lead to various respiratory issues such as asthma, bronchitis, and Emphysema.
PM can also enter the bloodstream and cause heart diseases like strokes and heart attacks. Children, the elderly, and those with previous cardiovascular or respiratory conditions are especially susceptible to the negative effects caused by PM exposure.
Types Of Particulate Matter
PMs are classified according to their dimensions, source, and chemical composition. These are the kinds of PM:
- PM10: Particles that have a diameter of at least 10 micrometers. They are tiny enough to breathe in and may cause respiratory issues.
- PM2.5: Particles with a diameter of 2.5 micrometers or less. They are much lower than PM10 and can penetrate the lung, leading to more serious health problems.
- Fine particles: Particles with diameters between 2.5 to 10 micrometers. They are derived from sources such as pollen, dust, and mold.
- Ultrafine particle: Particles of diameter that is less than 0.1 micrometers. They are tiny enough to enter the bloodstream and get to different body organs.
- Primary particles are released directly into the atmosphere from combustion engines or industrial processes.
- Secondary particles: Particles created in the atmosphere by the reaction of gases released from diverse sources.
- Organic particles: Particles that are made of carbon-based molecules. They are derived from sources like wildfires, vegetation, and the exhaust of cars.
- Inorganic particles: Particles composed of carbon-based compounds that are not non-carbon-based. They originate from various sources, including road dust, construction sites, and industrial processes.
The composition, size, and source of particles determine their health impacts and behavior in the surrounding environment.
Environmental Impact Of Particulate Matter On Air Pollutants
Particulate Matter (PM) is a kind of air pollution composed of small particles with various dimensions and compositions. PM results from human-made and natural sources, like transport, industrial activities, and wildfires. If inhaled, the PM could cause health effects. However, it also has major environmental effects.
PM can have environmental effects that are both indirect and direct. Direct impacts can include less visibility and staining of buildings, monuments, and other structures. For instance, The Taj Mahal in India suffers from discoloration caused by PM exposure. Furthermore, PM may cause water bodies and soils acidification, affecting aquatic life and plants.
The indirect effects of PM’s impact on our environment can be more complicated and lasting. For example, PM may alter the conditions of the atmosphere and cause changes to weather patterns, precipitation patterns, and even climate. In particular, the PM could influence clouds, altering the ability of clouds to develop and possibly altering the frequency and duration of rain.
PM may also contribute to global warming since it can absorb and reflect light. PM is among the primary components of black carbon, a powerful greenhouse gas. Black carbon may be deposited on snow and ice quickly, speeding up their melting and increasing sea levels.

Ozone is a chemical that is found naturally in the atmosphere of Earth. However, it can also be generated by human activities. If it forms at the ground level by chemical reactions between pollutants, it is a dangerous air pollutant. Therefore, ozone from air pollution is a significant threat to humans and the environment.
In the article, we’ll examine the causes and effects of ozone pollution in the air and methods to minimize its effects on our health and environment.
Sources Of Ozone In Air Pollutants
Ozone found in air pollutants is created by Nitrogen oxides (NOx) and volatile organic compounds (VOCs) that react with sunlight. The pollutants originate from many sources, such as power plants, transportation, industrial processes, and consumer products.
Transportation is the main source of NOx and VOCs, with vehicles, trucks, buses, and cars emitting huge amounts of VOCs and NOx into the air. Power facilities that use fossil fuels also are the biggest emitters of NOx. Likewise, industrial processes like manufacturing and manufacturing release NOx and VOCs.
Paints, consumer products like solvents, paints, and cleaning products also contain VOCs that contribute to the creation of Ozone from air pollution.
Effects Of Ozone On Air Pollutants
Ozone exposure to air pollutants can cause severe negative health consequences, particularly in vulnerable populations like young children, the elderly, and people with chronic respiratory or cardiovascular diseases.
Short-term exposure to excessive Ozone levels could cause irritation to the nose, eyes, and throat, as well as coughing. Ozone is a gas that exists in Earth’s atmosphere. It’s created by a chemical reaction of nitrogen oxides with volatile organic compounds under the influence of sunlight. Ozone may be dangerous to human health, especially when concentrations are very high.
Exposure to high Ozone levels can cause a range of respiratory symptoms, including coughing, chest pain, shortness of breath, and wheezing. Ozone can also irritate the eyes, nose, and throat, leading to redness, itching, and soreness.
In addition, high Ozone levels can aggravate existing respiratory conditions, such as asthma and chronic obstructive pulmonary disease (COPD), and may even trigger asthma attacks in some people. Long-term exposure to elevated levels of Ozone can also lead to permanent damage to lung tissue and decrease lung function.
To protect yourself from the harmful effects of Ozone, limiting your exposure to outdoor air when ozone levels are high, typically during hot and sunny days is important.
Visibility And Haze
Air pollution is among the biggest issues the world is currently confronting. It hurts the health of humans and the environment. Air pollution comes in many forms. However, the most frequent problems are visibility and Haze. In the article below, we’ll look at the definitions of visibility and Haze, how they are related to air pollution, and their impact on people’s health.
What Is The Definition Of Visibility?
Visibility refers to the distance from which objects are observed. It is frequently used to assess the quality of air. Therefore, it is a crucial aspect of aviation safety. Low visibility could be due to a myriad of reasons, like smoke, fog, or dust particles on the ground. However, the higher the air pollution concentration, the less visibility will become. The reason is that air pollution can absorb light and scatter it, making it difficult to discern through clouds.
What exactly is Haze? Haze is a type of air pollution that decreases visibility because it makes the air appear blurred or hazy. It’s caused by a mixture of air pollution, including particles and Ozone. Haze is typically observed in urban areas that have excessive levels of pollution. Still, it also occurs in rural areas due to causes like agricultural burning and forest fires.
What Air Pollutants Can Impact Visibility, And How Do They Affect Haze And Visibility?
Air pollution can influence the visibility of the area and the formation of Haze. Particulate Matter, for instance, can absorb and scatter light, which reduces visibility and creates fog. Ozone also plays an important role in forming Haze by reacting other air pollutants to create secondary pollutants like peroxyacetylnitrate (PAN).
Other air contaminants that create Haze and visibility are sulfur dioxide (SO2) and Nitrogen oxides (NOx), as well as volatile organic compounds (VOCs). SO2 reacts with other air pollutants to create Sulfate aerosols, which absorb and scatter light. In addition, VOCs and NOx can react with sunlight to create ground-level Ozone that can cause the formation of a Haze.
How Do Haze And Visibility Influence The Health Of Humans?
Haze and visibility can harm the human condition, particularly the cardiovascular and respiratory systems.
Haze is an aspect of air pollution that happens when small particles and droplets within the air absorb sunlight and scatter, which causes the atmosphere to look cloudy or smokey. These particles originate from various sources, including car emissions from industrial processes, exhaust, and wildfires.
Exposure to Haze and decreased visibility can lead to a myriad of health issues, including:
- Problems with the respiratory system: Haze can trigger irritation of your respiratory tract, leading to wheezing, coughing, breathlessness, or asthma attack. It may also worsen respiratory ailments, including chronic obstructive lung disease (COPD) or bronchitis.
- Heart problems: Haze may raise the chance of heart issues, like strokes and heart attacks, by causing inflammation and damage to the blood vessels.
- Itching eyes: The effects of Haze may irritate the eyes, such as burning, itching, and redness.
- Health and mental health: Haze may also harm mental health since diminished visibility can trigger feelings of stress, anxiety, and depression.
To avoid the negative consequences of Haze and reduced visibility, you must minimize the exposure you are exposed to by staying inside in the event of poor air quality and wearing a protective mask whenever you are outdoors. It is also advisable to examine the local air quality reports and stay clear of outdoor activities at periods when the air quality is at its worst.
Acid rain refers to a kind of precipitation that occurs by airborne pollutants like sulfur dioxide (SO2) and nitrogen oxides (NOx) interact with the water molecules within the atmosphere to create sulfuric acid (H2SO4) and nitric acid (HNO3). Acid rains can cause negative effects on the environment, which can destroy crops, forests, and aquatic life, as well as health consequences.
Sources of Acid Rain
Acid rain is mostly caused by human activity like burning fossil fuels for power production and transportation. Power plants that use coal and oil are major producers of nitrogen oxides and sulfur dioxide. In addition, motor vehicles, particularly those equipped with diesel engines, can contribute to acid rain. Other causes are industrial processes like metal smelting and chemical manufacturing, as well as agricultural practices, like fertilizers based on nitrogen.
Effects of Acid Rain
Acid rain’s consequences can be devastating and widespread. One of the main consequences is the damage it could cause to vegetation and forests. Acid rains can remove nutrients from the soil, which makes it hard for plants and trees to take in the nutrition they require to flourish. This can make weak forests and trees more prone to diseases and pests.
Causes of Acid Rain
Acid rain can be caused through a chemical reaction which is caused when pollutants like sulfur dioxide (SO2) and nitrogen oxides (NOx) are released into the air by human activities like burning fossil fuels for power plants, transportation, and also by natural sources like volcanoes.
They react with oxygen, water, and other compounds in the atmosphere to produce sulfuric acid (H2SO4), Nitric acid (HNO3), and nitric acid (HNO3), which later drop to the ground and form acid rain.
The principal source of nitrogen dioxide, as well as sulfur dioxide, are:
- Power plants: Coal-fired power stations are the main source of sulfur dioxide emissions. Natural gas-fired and coal-fired power plants contribute to nitrogen oxide emission.
- Transportation: Trucks, cars, and other vehicles which burn fossil fuels are major emitters of nitrogen oxide.
- Industries and processes: The combustion of fossil fuels in manufacturing processes, like cement production, also contributes to nitrogen oxide and sulfur dioxide emissions.
- The eruptions of volcanoes: The eruptions of volcanoes emit sulfur dioxide as well as other gases into the atmosphere. This can cause acid rain.
Sources Of Air Pollutants
There are a variety of sources of air pollutants which include:
- Transportation: Trucks, cars, buses, as well, and other vehicles emit harmful pollutants like carbon monoxide, particulate matter, nitrogen oxides, and other volatile organic compounds.
- Industrial Processes: Power plants and factories release pollutants like carbon monoxide and nitrogen oxide particulate Matter, as well as carbon monoxide.

- Smoke from Tobacco: Smoking releases pollutants like formaldehyde, carbon monoxide, and other particulate matter into the air.
Secondary Air Pollutants
Secondary air pollutants are formed in the atmosphere through chemical reactions involving primary pollutants and other substances present in the air. Primary pollutants are those emitted directly into the air from natural and anthropogenic sources such as vehicles, factories, and power plants.
Examples of secondary air pollutants include Ozone (O3), sulfuric acid (H2SO4), nitrogen dioxide (NO2), and Particulate Matter (PM2.5 and PM10). These pollutants are formed through complex reactions involving primary pollutants such as nitrogen oxides (NOx), sulfur dioxide (SO2), and volatile organic compounds (VOCs).
Ozone, for example, is formed when nitrogen oxides and volatile organic compounds react in sunlight. Sulfuric acid is formed when sulfur dioxide reacts with water vapor and oxygen in the atmosphere. Likewise, nitrogen dioxide is formed through the reaction of nitrogen oxides and sunlight.
Secondary air pollutants can have harmful effects on human health and the environment. Ozone, for example, can cause respiratory problems, while sulfuric acid can cause acid rain, damaging buildings, crops, and forests. Particulate Matter can also adversely affect human health, particularly the respiratory system.
