Understanding and Preventing Air Pollution
Air pollution is a major problem affecting the entire world. In the United States some progress has been made in reducing air pollution through the Clean Air Acts passed by the Congress. Still there is a lot to be done. To prevent air pollution it is important to understand how the air is being polluted, how it impacts on the ecosystem and what we can do about it.
Earth is surrounded by layers of gases known as atmosphere. The layer closest to the earth is called the troposphere. It extends up to ten miles above the surface of the earth. Over the troposphere is the stratosphere which extends from ten to forty miles above the earth ( Gutnick pg. 9). Ozone is a part of the stratosphere that blocks the sun’s harmful ultraviolet rays from reaching the earth. Over the stratosphere is the ionosphere which extends up to 400 miles ( Sandak pg. 37 ). In the ionosphere, the gases are broken into individual electrically charged particles called ions ( Gutnik pg. 9 )
Air, as we know, is the mixture of gases in the troposphere closest to the surface of the earth. It is mainly composed of nitrogen (78%), oxygen (21%), carbon dioxide (0.02%), argon and other rare gases (0.08%). Air pollution takes place when undesirable gases and particles mixes with the air to cause harmful effects on living and non-living things ( Becklake pg. 6 ).
There are many types of air pollutants which can be put under three basic categories. These are - gaseous, particulates, and aerosol.
Gaseous pollutants is any harmful gas that mixes into the air. Gaseous pollutants could be divided into four major groups. These are - carbon based gases, sulfur based gases, ozone, and nitrogen based gases ( Gutnik pg. ...

There are six common pollutants in the air, which include ozone, particulate matter, carbon monoxide, nitrogen oxide, sulfur dioxide, and lead. These pollutants led to many different symptoms across the United States. Ozone pollution leads to impaired respiratory system. Particulate matter affects respiratory systems, causes cancer, and premature death. Carbon monoxide affects the bloodstream and reduces oxygen to the body’s organs. Nitrogen oxide causes influenza. Sulfur dioxide effects respiratory illness and pulmonary defenses. Lead causes effects in the liver,
More than three million children under the age of five have passed away because of pollution and other environmental factors (Rinkesh). Pollution is the leading cause of death among developing countries (Petru, Alexis). Air pollution analyst and environmental chemist are two careers that focus on improving our environment to make it safer to live in.
In an era of rising technology and increasing population, demands on the environment are continually being pushed to new levels. As a result, it becomes important for us to expand our knowledge about the environment and take appropriate actions to protect this element of most importance to human existence. One component of our environment experiencing some of the greatest abuse due to humans is the air. Air pollution has been on the rise ever since the beginning of industrialization. The climbing number of factories and use of cars worldwide are the major culprits of this environmental hazard. There are various gases released into the air that can be considered air pollutants, but one of the most prevalent and dangerous to the environment is carbon dioxide (CO2). Up to 95% of the CO2 produced is the result of natural processes (Burnett & Matthews Jr., 1998). The rest is a direct result of human activity, primarily through the burning of fossil fuels in the production of energy
...such as recycling and reducing waste has significantly helped our environment and will continue to if future generations practice these same habits. For deforestation, many organizations have strived to plant more trees and add more oxygen to the atmosphere as well as nutrients for the soil. Seeing that although humans create many negative impacts in our global environment, there are many positive arrangements in correcting these issues.
One of the most dangerous environment issues Southern California is facing today is air pollution. This includes the burning of fossil fuels and natural disasters. Los Angeles is one of the most polluted cities in the world, and the most polluted city in the United States. I will research information about the causes, the effects, and the history of air pollution in the Los Angeles. For my research, I have relied mostly on, the school’s database and library, as well as current events.
Relevance: Air pollution is something that everyone should be concern, especially if we’re advancing a lot in technology, especially in vehicles and the importance of our air or the environment.
Air pollution is caused by many things such as car fumes, burning of fossil fuels,
There are many kinds of air pollution. The ones I want to talk about are the ozone, acid rain, carbon monoxide and toxic air contaminants. Ozone is formed when hydrocarbons and nitrogen oxide react in sunlight. Therefore, ozone is at its peak during hot summer days. Exposure to high levels of ozone can have serious consequences on your health. It can cause respiratory disease, loss of pulmonary elasticity, and premature aging of our lungs. Next, is acid rain, which occurs in the atmosphere in the form of sulfur and nitrogen oxide. These pollutants can have serious damaging affects on aquatic, forest and wildlife ecosystems, as well as deterioration of buildings. Carbon monoxide is another form of pollution. It reduces the blood?s ability to carry oxygen. If a human is exposed to higher levels, it can cause chest pains, angina attacks or even death.
...mful diseases, cleaner environment, last but not the least, saving the planet for our future generation.
Air pollution according to the Wikipedia << is the introduction of particulates, biological materials, or other harmful materials into the Earth’s atmosphere, possibly causing disease, death to humans, damage to other living organisms such as food crops, or the natural or built environment>>. Therefore, human being should be aware of the facts that the environment and all living creatures are dying. They need to understand the importance of natural items, the nature, etc…
Air pollution is a type of pollution that can severely damage our environment as well as the earth’s atmosphere. Air pollution occurs all the time when the air contains many substances ...
Protect oceans from overfishing and establish a global whale sanctuary. Protect the world's remaining old growth forests. Eliminate sources of dioxin and other persistent organic pollutants (POPs) including PVC, and ensure legislation to prevent toxic waste dumping. Protect future generations from the effects of nuclear contamination by ending the nuclear fuel cycle, stopping radioactive discharges and plutonium shipments.
Air pollution is when a poisonous or harmful substance is released into the air. There are many forms of pollution but air is one of them, it only occurs when dust, harmful gases or smoke enters into the atmosphere and makes it hard for species like plants, animals and humans to live in a difficult situation because of the dirty air. Air Pollution is classified in two sections, invisible air pollution and visible air pollution.. Hence any substance that makes it difficult for the living things that need the atmosphere is air pollution. Humans have been undergoing air pollution ever since the industrial revolution.
Other methods such as hydroelectricity, using more timber in architecture to sequester carbon, wind energy instead of modern high polluting techniques to help enhance our environment. There are various systems in handling population rates and the various issues that connect with threatening our environment. The population and environment debate will forever be a back and forth problem because there is possibly no way to completely stop carbon emissions but ease its production. To help the environment, we must incorporate all potential solutions in governing population such as family planning and governmental involvement and practice renewable resources and stop using nonrenewable resources, as well as ways to tackle overconsumption to support our corrupt environment.
The amount of water that is on earth at any one time remains fairly constant because the water is moving form one reservoir into another such as river to ocean or ocean to atmosphere. This cycle involves the exchange of energy causes a change in temperature. This is why when evaporation occurs, it takes energy from its surroundings and cools the environment. While condensation occurs energy is released and the surrounding environment becomes warmer. The atmosphere is a mixture of nitrogen, oxygen, and other gasses that surround the earth. The atmosphere is made up of five layers known as the troposphere, the stratosphere, the mesosphere, the thermosphere, and the exosphere. The troposphere is the lowest layer of the earth’s atmosphere; it is also where all weather on earth takes place. The stratosphere is the second layer of the atmosphere, right above the troposphere. Above the stratosphere is the mesosphere and above that is the troposphere. The uppermost region of earth’s atmosphere is the exosphere. The air in the exosphere is extremely thin and almost the same as space. One of the many reasons the earths atmosphere is important is because it blocks
