Pollution
Introduction
Pollution is the introduction of contaminants into an environment that causes instability, disorder, harm or discomfort to the ecosystem i.e. physical systems or living organisms. Pollution can take the form of chemical substances or energy, such as noise, heat, or light. Pollutants, the elements of pollution, can be foreign substances or energies, or naturally occurring; when naturally occurring, they are considered contaminants when they exceed natural levels.
Pollution became a popular issue after World War II, due to radioactive fallout from atomic warfare and testing. Then a non-nuclear event, The Great Smog of 1952 in London, killed at least 4000 people.This prompted some of the first major modern environmental

Ground level ozone (O3) formed from NOx and VOCs. Ozone (O3) is a key constituent of the troposphere (it is also an important constituent of certain regions of the stratosphere commonly known as the Ozone layer). Photochemical and chemical reactions involving it drive many of the chemical processes that occur in the atmosphere by day and by night. At abnormally high concentrations brought about by human activities (largely the combustion of fossil fuel), it is a pollutant, and a constituent of smog.
Peroxyacetyl nitrate (PAN) - similarly formed from NOx and VOCs.
Minor air pollutants include:
A large number of minor hazardous air pollutants. Some of these are regulated in USA under the Clean Air Act and in Europe under the Air Framework Directive.
A variety of persistent organic pollutants, which can attach to particulate matter.
Persistent organic pollutants (POPs) are organic compounds that are resistant to environmental degradation through chemical, biological, and photolytic processes. Because of this, they have been observed to persist in the environment, to be capable of long-range transport, bioaccumulate in human and animal tissue, biomagnify in food chains, and to have potential significant impacts on human health and the environment.
Health effects of Air Pollution:
The World Health Organization states that 2.4 million people die each year from causes directly attributable to air pollution, with 1.5 million of these deaths attributable to indoor air
Pollution is one of the biggest global killers, affecting nearly 100 million people. Pollution comes in many different forms and affects the world and the environment in many different ways. Along with the best known pollutants such as water, air, and land, there are other pollutants that many people do not know much about. These include light, noise, thermal, and household pollution and are all just as damaging as the most known ones. Pollution is an introduction of a harmful or poisonous substance into the environment that has a negative effect on life around it. Pollution is deadly, and it is destroying the only world suitable for life. Pollution is a
Air pollution is generally any substance that people introduce into the atmosphere that has damaging effects on living things and the environment.(www.nationalgeographic.com/environment/global-warming/pollution/) There are many causes, effects and many reasons like the environment, public health, and any other reasons. Air pollution is harmful for our present and future lives and should be avoided at all costs.
Another big problem in polluting places and things is air pollution which can make air foggy, unbreathable, and toxic. According to “34 Facts about Pollution”, the text states breathing the air in Mumbai, India, for just one day is equivalent to smoking 100 cigarettes. One of the things that can cause air pollution is releasing factory fuels and fossil fuels into the air. We also cause it from burning certain things like plastic, chemicals, and other
Pollution is defined as the process of harmful substances being released into the air. Some of these substances include Carbon Monoxide, Sulphur dioxide, Lead and PM2.5. PM2.5 is small particles which are smaller than 25 thousandths of a millimeter. This polluted air will fill your lungs with tiny particles and cause Lung cancer, Asthma and other heart and lung diseases.
Since human’s activity, pollution becomes a big problem in the world. There are a lot of part of pollutions include water pollution, light pollution and air pollution. Air pollution is happened in our life. The United States is also a victim of air pollution. In 1943, Los Angeles photochemical smog event occurred. The whole of Los Angeles was covered with smoke. There are about 400 people died and a lot of fruits in orchards began to wither.
2. London has suffered from terrible air pollution for at least seven centuries. Why is the city so prone to its famous “London fog?” What did London do to get rid of its air pollution? Because of The terrible events in Pennsylvania and London, plus the recognition of the hazards of photochemical smog. They did the Clean Air Act in 1970 in the United States. The act now regulates 189 pollutants.
What is pollution? It is the introduction of a contaminant into a natural environment, usually by humans. Most of us think of pollution as chemical waste being dumped into rivers or factories spewing toxins into the air. Pollution can be as simple as throwing your trash in a river or leaving it on the riverbank. This trash often causes problems for our wildlife in and around the river.
The earth is a wonderful place which we share with the plants, animals and birds. We must preserve the land we live on. A pollutant is any substance which contaminates the air, water and land. Pollution is the introduction of harmful substances or products into the environment or harmful changes that occur in the environment due to human actives are pollution. Pollution could be in air, water and land. As these harmful substances, gases and quality of life of all living beings will affect the humans. Pollution is very dangerous for health, environment, can cause sickness death in living beings, unnatural weather conditions and damage the crops. Pollutants are the key elements or components of pollution which are generally waste materials of different forms. Pollution disturbs our ecosystem and the balance in the environment. With modernization and development in our lives pollution has reached its peak; giving rise
Pollution is not new to the environment, it has been seen for decades. Writers such as Plato, Dickens, and Engels have wrote about how pollution was in their own time. Although pollution was prevalent back then, in the past three decades the concern has greatly increased. This in turn has caused an increase in appreciation of the materials provided to us from the earth. Pollution itself literally means dirty. Pollution occurs when the land, water, and air are contaminated by the addition of harmful substances. An imbalance occurs in the environment which threatens every aspect of life in the world. In A Town Plagued by Water the egg farm of Samuel and Bertha Reich was a major example of this kind of destruction. When the egg farming didn't
There are so many pollutants in the air today. They come from many different sources. The most common types of gases come from automobiles, power plants, and industrial companies. This leads to poor quality in the air, along with global warming, and heavy pollution. The gases that are released into the air can be very dangerous for humans and animals alike. Many of the toxins cause cancer and other diseases. This has been going on for many, many years. The United States and China are two good references to compare.
Different processes like fossil fuel burning in industries, motor vehicles, and buildings all emit hazardous waste into the air that lead to air pollution. Some of the pollutants released into the air are particulate matter and ground level ozone which are the main ingredients in smog, along with nitrogen oxide, sulphur oxide, volatile organic compounds, and carbon monoxide. Ground level ozone and soot are direct contributors to air pollution and a higher temperature increase. Recent studies have shown that in the upcoming years with temperatures rising ozone will be released into the atmosphere at much higher levels than previously seen. This increase in ozone will be very harmful as it can cause health problems for children, the elderly, and anyone with lung diseases such as asthma. Along with affecting us humans ground level ozone is harmful on vegetation and ecosystems that support all kinds of plant and animal life. Some factors that affect ozone formation are heat, concentrations of precursor chemicals, and methane emissions. An increase in global temperature can lead to more premature deaths caused by worsened ozone and particle pollution. Studies have shown that if no change is made in air pollution premature deaths due to these factors will rise anywhere from 1,000-4,300 additional deaths per year by 2050. Us humans in everyday life contribute
Air pollutions is a major problem across the united states and around the world. It is also probably the most serious environmental problems today. The term air pollution is just kind of tossed around and not taken as serious anymore although its effects are becoming greater. Air Pollution is toxic chemicals in the air, that can also be compounds and they are extreme enough to cause health risks. (Frank) This is damaging the ozone layer and creating global warming.
Pollution is caused by both human and natural events. There are many different types of pollution. Some of these types of pollution include air, water, and land pollution.
Pollution is caused by people littering, throwing their trash everywhere, wasting energy, and burning fuel from vehicles. Pollution effects all animals and plants from around the world. It can harm them and kill them. Some animals have gone extinct because of pollution, thanks to humans. To be exact, over 11 species of animals have gone extinct because of pollution, Not to mention people have died too! How much? Well, about 6.5 million people have mainly because of respiratory problems (lung cancer caused by air pollution) . Yea, its really bad. Pollution has been around for a long time in the U.S since the mid-19 centuries. It got worse because of the industrial revolution. This caused the air and water to become polluted because of all of the manufacturing factories, which uses coal for their factories and threw their waste
The pollution levels have been increasing lately.Pollution is the dumping of waste or any harmful substance that can have a negative effect on the environment.Examples consist of the BP oil spill when tons of oil was spilled into the waters of the gulf of mexico,This put animals in danger and the water was contaminated.Organizations have been coming together to find a solution to the pollution. The pollution has been taking a toll on our environment all over the world.Global warming has been a major ongoing problem for a long time because humans are eliminating recyclables improperly, fumes are affecting the air, and oil is disposed of in the oceans.
