It results whenever harmful gasses, smoke, or dust enters the atmosphere and in turn, hinders the survival of animals and plants as the air contains toxic substances. The survival of human beings and animals greatly depend on the combination of gasses in the atmosphere; slight disruption of this composition can cause devastating effects on their existence. An imbalance in these atmospheric gasses is known to result in global warming, a great threat to the contemporary world.
We cannot underestimate the effects air pollution has on the ozone layer which largely contributes to the existence of organisms on the planet. Causes of Air Pollution For the causes of air pollution to be well articulated, it is important to delve into the types of air pollutants. Air pollutants can be caused by secondary and primary sources. If a process directly results to pollution, then this forms the primary source.
For instance, the intermingling of primary pollutants forms smog which is a secondary pollutant. Burning of fossil fuels The main cause of air pollution is burning of coal, gasoline, petroleum, and other fossil fuels. These fuels are the main cause of acid rain, smog, greenhouse gas emissions, and presence of heavy metals in the air. Concentration of industries in one area is another major cause of air pollution.
Effect of Air Pollutants: Air pollutants are broadly classified into particulate and gaseous. The particulate substances include solid and liquid particles.
The gaseous include substances that are in the gaseous state at normal temperature and pressure. The air pollutants have adverse effect on human beings, animals, vegetation, buildings. Aesthetic sense is also influenced by air pollutants.
The different air pollutants and their effects are as follows: 1. Particulate Matter: It is of two types—settleable and suspended. The settleable dusts have a particle longer than 10 am. The smaller particles are able to remain suspended for long periods in the air. The important effects of particulate matter are.
Smog harms plant life through glazing and necrosis besides reduced availability of light. Stationary sources are mostly industrial complexes such as factories and electric generating plants.
Mobile sources are vehicles, on- road, off-road. The quality of the indoor air also plays a significant role as far as health is concerned. Ambient air pollution is outdoor pollution originating from industries, cars, and trucks. These pollutants can wreak havoc on the human respiratory system Ambient air pollution.
Air pollution affects our environment because it causes health problems, negatively affects the economy, and causes drastic weather changes. Air pollution is one of the world 's biggest killers. It is made up of gases that are released into the air in large quantities.
These gases are capable of harming humans, animals, plants, and our climate. Approximately two million people die prematurely from air pollution each year. The black smoke, and sometimes invisible pollutants, are causing harm all over the earth without people realizing it.
Car pollution can cause disruption to human 's health, the environment, and the cities in just a matter of time and in many different ways.
Could it have been in the A. D era when cave people built small fires to survive? No one will be able to specifically say but what we can attest to is that since the A. D era we have contributed several times over to Air Pollution. We risk breathing in dangerous chemicals every time we breathe. Particular Matter Both PM2. The particular matter is commonly used indicator of air pollution in the research. Our geography and air pollution policies are such that it is not a major health risk here as it is in some other developing countries.
In India, however, their economy is growing so rapidly that they are not taking into consideration their environmental impact. As developing countries grow, their economies shift from agrarian to industrial to technological. In some ways, this is good for the people. This research paper will focus on the major source of air pollution, factors responsible for poor air quality, impacts of air pollutants in the valley, and regulations.
When fossil fuels are burned, they let out oxides into the air. When these oxides mix with water in the atmosphere, they make acid, which fall as precipitation. Acid rain can also damage buildings made of limestone and concrete.
Ozone hole[ change change source ] A global concern is the hole in the ozone layer in the stratosphere. The Earth's ozone layer protects life from the Sun's harmful ultraviolet rays, but in the s, scientists found out that some chemicals let out into the atmosphere makes the ozone turn into oxygen. This lets more ultraviolet rays reach the Earth. Air Pollution Essay 6 words Increasing concentration of the harmful and toxic materials in the fresh air of the atmosphere is causing air pollution.
Variety of foreign particles, toxic gases and other pollutants released from various human activities are affecting the fresh air which has adverse effect to the living beings like human beings, animals and plants. The level of air pollution depends on the type and amount of pollutants released from various sources. Topographical and meteorological conditions are increasing the spread and concentration of the pollutants. Variety of raw materials used in the manufacturing process in industries is increasing the type and quantum of emissions of harmful gases.
Increasing population density is demanding the need of more industrialization which ultimately causes air pollution. Air Pollutants like harmful liquid droplets, solids particulates, and toxic gases oxides of carbon, halogenated and non-halogenated hydrocarbons, nitrogen and sulphur gases, suspended inorganic particulate matters, inorganic and organic acids, bacteria, viruses, insecticides etc which are generally not the constituents of fresh air are very hazardous to the plant and animal life.
There are two types of air pollution sources which are natural sources and man-made sources. Some natural sources of the air pollution are like volcanic eruptions, volcanoes ashes, carbon dioxide, smokes, dust and other gases , deflation of sands, dusts, salts spray from seas and ocean, soil particles, storms, forest fires, cosmic particles, rays, bombardment of asteroid materials, comets, pollen grains, fungal spores, viruses, bacteria, etc.
Man-made sources of the air pollution are industries, agriculture, power plants, automobiles, domestic sources, etc.
Some of the air pollutants from the man-made sources are like smokes, dust, fumes, particulate matters, gases from kitchen, domestic heating, emissions from different vehicles, use of insecticides, pesticides, herbicides, heat created from power plants, smokes, fly ash, etc.
Because of the increasing number of air pollutants, it has been divided into two types such as primary pollutants and secondary pollutants. Primary pollutants are those affecting the fresh air directly and emitted from smoke, ash, dust, fumes, mist, spray, inorganic gases, carbon dioxide, carbon monoxide, sulphur dioxide, hydrogen sulphide, ammonia, nitric oxide and radioactive compounds.
Secondary pollutants are those affecting the air indirectly by chemical interactions to the primary pollutants and other atmospheric constituents such as sulphur-trioxide, ozone, hydrocarbons, nitrogen dioxide, etc.
Attempt should be made to develop pollution free fuels for automobiles, e.
Most air pollution made by humans today is because of transportation. Natural and trash to make air is a push dbq era of air pollutants including stroke, Aesthetic sense is also influenced by air pollutants. As we all know that fresh air is the most important element of the healthy life, we need to think that what happens if whole atmospheric air gets dirty. Air pollution caused by cars and airplanes do a lot more damage to the world than most people are aware of. For instance, these natural causes include volcanic eruptions.
Indoor air travel, and high-quality paper essay natalia ginzburg essays and food transportation. Environment also suffers. In modern society, the use of fossil fuels can be made so that its burning becomes efficient, but this comes with a monetary cost. Air pollution is the introduction of particulates, biological molecules, and many harmful substances into Earth 's atmosphere, causing diseases, allergies, and death to humans, damage of other living organisms like animals and crops, or the natural environment National Geographic, Air pollution is continuously damaging the whole ecological system and affecting the lives of plants and animals as well. Increasing level of harmful gases in the environment are causing the occurrence of acid rain and depleting the ozone layer.
Contributing to change there are the bureau of this summer as humans in patna. Human beings can live a few days without food and water however humans can last only a few seconds without oxygen. Industrialization process releases many harmful gases, particles, paint and batteries contains lead, cigarettes releases carbon monoxide, transport means releases CO2 and other toxic substances to the atmosphere. Compounds inside carpets, paints, building materials and furniture also pollute the air, especially when they are new.
