A pollutant released into the atmosphere is known as air pollution. Pollutants such as these are bad for health and the overall health of the environment. Global air pollution is estimated to cause nearly seven million deaths each year, according to the World Health Organization (WHO) estimates. People in low and lower-middle countries are the most affected, with nine out of every ten breathing air that exceeds the World Health Organization’s guideline limits for pollutants. Air pollution is most prevalent in large cities, where emissions from a wide range of sources are concentrated in one place.
Air pollution
Air pollution is a combination of hard particles and gases that exists in the atmosphere. Particles can be formed from a variety of sources, including vehicle exhaust, toxins from factories, contaminants, dust mites, and mold spores. As ozone contributes to air pollution, it is referred to as smog.
Causes of air pollution
- Air pollution can be caused by some gases in the atmosphere. Among the most significant sources of air pollution in urban areas is an oxygen-depleting gas known as ozone (ozone).
- Additionally, ozone is a greenhouse gas with the potential to be both beneficial and detrimental to our environment.
- Everything is dependent on the location of the object in the Earth’s atmosphere. Our atmosphere contains beneficial amounts of ozone at high altitudes. It aids in the prevention of harmful solar radiation, which is emitted by the Sun.
- The opposite is true when ozone is located low on the earth and can be extremely harmful to our health.
- Sun’s rays react with some of these chemicals released by sources of fossil fuel combustion, like factories or automobile exhaust, to produce ground-level ozone, which is toxic to humans.
- It is the smog that is formed when airborne particles combine with ozone.
- Air pollution known as smog has the appearance of thick, smoky fog as well as makes visibility difficult.
Environmental effects of air pollution
An ecosystem is comprised of plants, animals, and other life forms, as well as their surrounding environment, which includes air, water, and soil. When something causes harm to one component of an ecosystem – a single type of animal or plant, the soil, or even the water – it has the potential to significantly impact the entire ecosystem. Air pollution is hurting the environment where we live. The following are the most significant environmental consequences:
-
Acid Rain-
It is in aquatic environments such as rivers, ponds, and wetlands that the environmental effects of acid rain are often visible, where it could be toxic to fish and other wildlife. Acid rain has been linked to a variety of diseases. Acidic rainwater can release toxic aluminium from ground clay minerals as it continues to flow through the soil and then into lakes and rivers as it continues to flow through the soil. In addition to acidifying soil and water environments, they can also cause damage to trees and plantations, as well as damage to buildings, as well as outdoor sculptures, structures, and statues.
-
Haze-
In addition, the pollination of flowers is hindered by smoke-filled conditions. Specifically, according to Huang, carbon-based nanoparticles in the fog may also dissolve with rainwater and cause acid rain, which could have a fatal effect on plant functions and cause ecosystem damage as a result. As small particles are scattered in the atmosphere and impair the visibility of the atmosphere, haze is created. Manufacturing sites, power stations, automobile manufacturing, and trucks all contribute to the pollution of the environment by emitting gases into the atmosphere.
-
Ozone-
Ozone causes damage to vegetative cover and biodiversity by interfering with the ability of trees and shrubs to breathe through the tiny cracks on their leaves that allow them to transpire. The reduction in the amount of CO2 that can be processed and released as oxygen hurts the photosynthesis process. In the atmosphere just above the earth’s surface, ground-level ozone can be seen as a colourless and highly irritating gas.
-
Greenhouse effect-
Some air pollutants contribute to the warming of the climate. The latest increase in carbon dioxide pollution is going to cause the weather to heat up by catching extra heat and starting to cause it to warm. Carbon dioxide and other greenhouse gases are among the pollutants in the air. Greenhouse gases end up causing the weather to warm by absorbing heat from the Sun and retaining it in the Earth’s atmosphere for long periods. As temperatures rise, people who live in poorly maintained building structures in warmer areas are at increased risk of developing heat-related illnesses, according to the WHO.
-
Wildlife-
Lung problems, heart issues, inflammatory processes, and cancer are some of the consequences of air pollution in animals’ lives. Pesticides sprinkled on crop production or lawns can have adverse effects on animals as well as on humans. The environment is burdened by harmful gases that originate in the air, soil, or water ecosystems. Animals that are exposed to high levels of toxic pollutants can develop health problems. There have been reports of infertility and adverse birth outcomes. Animals and humans alike are affected by air pollution, which produces genetically inherited disorders as well as other medical problems.
Conclusion
Various types of pollution enter the Earth’s atmosphere through a variety of channels. The majority of air pollution is caused by humans, and it manifests itself in the way of industrial emissions, automobiles, planes, and aerosol cans. In addition, secondhand cigarette smoke is considered to be an air pollutant. Anthropogenic sources are the sources of pollution that are caused by human activity.
Naturally occurring air pollution includes things like smoke from wildfires and ash from volcanoes, to name a couple of examples. These are referred to as “natural sources.”
Mountains and tall buildings can sometimes act as a barrier, preventing air pollution from spreading. This air pollution manifests itself in the form of a cloud, which makes the air murky. It is referred to as smog.
