...Sharita Rogers Natural Science Cluster Dr. J. Kullman April 25, 2013 Air Pollution kills over 1 million in China I found this article titled “Air Pollution Linked to 1.2 Million Premature Deaths in China” in The New York Times on April 1, 2013. I found it interesting because prior to reading this article, I did not know air pollution was such a big problem, particularly in China. Edward Wong, journalist for The New York Times, wrote this article about premature deaths due to outdoor air pollution. According to Wong, air pollution is linked to 1.2 million premature deaths in 2010. This is nearly 40 percent of the global total. Ambient particulate matter pollution was the 4th leading risk factor for deaths in China. A study showed that the growth rate of disclosure of pollution information has slowed; meaning China is not disclosing this information to the public. China needs to figure out how to get a handle on their air pollution problem. China is no stranger to air pollution. According to the article, 350,000 to 400,000 people die prematurely each year because of outdoor air pollution. This is nearly 40 percent of the global total. In 1990, air pollution killed 800,000 people prematurely world wide. India also has densely populated cities that struggle with air population as well. India also had 620,000 premature deaths in 2010. The Organization for Economic Cooperation and Development stated that “urban air pollution is set to become the top environmental cause of......

... AIR POLLUTION Name Name of institution Describing the extent of PM2.5 in Indiana is problematic since the PM2.5 monitors are located in cities which make it rather problematic to know the concentration of PM2.5 in rural areas. Children are at grander risk from exposure to air pollution than grown-ups because their bodies are still growing. In relation to PM2.5 and air pollution in Indiana, children have elevated the level of absenteeism in school, asthma exacerbation and new on set asthma (Kunzli et al, 2003). My area of residence is Illinois, Chicago. The ambient airborne particulate matter concentration for Chicago is PM2.5 36 µg/m3. The Air Quality Index as of July 12, 2013 for Chicago was 58 and 42 on the thirteenth with the critical pollutant being the Ozone. The ambient air particulate Matter for Beijing china for PM10 is approximately 55µg m-3 and for PM2.5 is 152 µg m-3. The particulate matter between Chicago and Beijing has a huge significant difference. The PM2.5 of the city of Beijing is extremely higher than that of Chicago. The U.S. National ambient air quality standard for PM2.5 is 12.0µg m-3. The particulate matter level for the two cities is very high above the ambient air quality standard for US. The current air quality index of Beijing is at 152 while in Chicago is currently at 42. The air quality index of Beijing is very unhealthy in comparison to the standard air quality index figures. Also in comparison to Chicago, Beijing’s air quality index is on the...

...With the great concern surrounding the destruction of the earth’s atmosphere due to air pollution, the immediate and direct harm caused to the human body is often over shadowed. While many are aware that our careless use of hazardous chemicals and fossil fuels may leave the planet uninhabitable in the future, most over look the fact that they are also cause real damage to our bodies at this moment. Such pollutants cause damage to our respiratory system, leading to the fluctuation of the life span of an individual depending on a number of conditions. Amongst these conditions are the individuals specific geographic location, age, and life style. This paper is structured as a series of relevant questions and answers to report on the description of these pollutants there affects on our bodies. What are the pollutants? And how do they affect our bodies? In order to understand how air pollution affects our body, you must under stand exactly what this pollution is. The pollutants that harm our respiratory system are known as particulates. Particulates are the small solid particles that you can see through a ray of sunlight. They are products of incomplete combustion in engines (example: automobile engines), road dust, and wood smoke. Billions of tons of coal and oil are consumed around the world every year. When these fuels burn they produce smoke and other by-products into the atmosphere. Although wind and rain occasionally wash away the smoke given off by power plants and......

...Air pollution is the introduction of chemicals, particulates, biological materials, or other harmful materials into Earth's atmosphere, possibly causing disease, death to humans, damage to other living organisms such as food crops, or to the natural or built environment. The atmosphere is a complex natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems. Indoor air pollution (see Airlog) and urban air quality are listed as two of the world’s worst toxic pollution problems in the 2008 Blacksmith Institute World's Worst Polluted Places report.[1] ------------------------------------------------- Pollutants[edit] An air pollutant is a substance in the air that can have adverse effects on humans and the ecosystem. They can be solid particles, liquid droplets, or gases. A pollutant can be of natural origin, or man-made. Pollutants are classified as primary or secondary. Primary pollutants are usually produced from a process, such as ash from a volcanic eruption. Other examples include the carbon monoxide gas from motor vehicle exhaust or the sulfur dioxidereleased from factories. Secondary pollutants are not emitted directly. Rather, they form in the air when primary pollutants react or interact. Ground level ozone is a prominent example of a secondary pollutant. Some pollutants may be both primary and secondary: they......

...Air Pollution CaTina Massey Environmental Science November 12, 2011 Instructor: Professor Mahoney AIR POLLUTION Air pollution is the biggest problem we as Americans face today. The problem arose during the industrial revolution and has just gotten worse since then. However, the industrial revolution brought many great changes to the world; better transportation, cheaper merchandise, and has made our life better. In the beginning of the industrial revolution, the problem of pollution was not something that people paid attention too. As the science involved, people began to realize the problem with pollution. Many different sources cause air pollution. Automobiles that are burning gasoline produce very harmful gases and incineration of products. Factories produce millions of particles that are carried off into the air. Gaseous by-products produced by chemical plants release these toxic gases when their concentration is at a high enough level. As the world has become more industrialized, the increased amount of air pollution and new health hazards have developed. Air pollution can arise from different sources that we cannot control. For example, forest fires, dust storms, and volcanoes. One of the sources of air pollution is acid rain. Raindrops that are combined with polluted air create acid rain. Acid rain mainly causes the erosion of buildings, destruction of crops, and many other assets. Global warming is also caused by acid rain. Many......

...period of time.2 At the same time the negative environmental externalities of economic growth have escalated and are causing concern not only within China itself but also globally. China has suffered severe ecological destruction and serious environmental problems which threaten both its economy and the health of its people. Apart from air and water pollution, unprecedented growth in household and industrial waste, loss of biodiversity, felling of rain rainforests and overfishing has occurred. On a global level, China’s air pollution levels have contributed substantially to the negative effects of climate change. China’s rapid growth has been accelerated through its membership of the World Trade Organization (‘WTO’)3 and policies of trade liberalisation. Foreign investment has escalated due to preferential tax treatment and the relaxation of bureaucratic obstacles which in the past had slowed down the process of getting projects up and running. Special Economic Zones (‘SEZs’) set up in coastal provinces in order to encourage foreign investment because of easy access to port facilities have proven to be highly attractive to foreign investors. SEZs offer special incentives such as lower taxes, tax holidays, local tax reductions and greater independence in international trade activities. Today there are many such zones all over China both at the national and local level. A virtually limitless supply of cheap labour is a further bonus for investors. The overall result has *......

...Joann Lee Geology Research Paper December 1, 2014 Air Pollution Air pollution can be described as any contaminate or harmful substance to the atmosphere that disturbs the natural composition and chemistry of the air, causing damage to the environment, human health and the quality of life. The air that we breathe is filled with substances and pollutants that are hazardous to our health and these pollutants in the air can take many forms such as gases, solid particles or liquid droplets. Pollution enters the Earth’s atmosphere in many different ways. Air pollution can be created naturally, for example smoke from wildfires or ash from volcanoes, but most air pollution is created by humans, especially from the release of emissions from factories, cars, planes and etc. Air pollution that occurs naturally is considered as a natural source and air pollution caused by humans are called anthropogenic or man-made sources. Air pollution is the most common in large cities due the high volume of people and some of the most polluted cities in the world are Beijing, New Delhi, Los Angeles and Cairo. Although air pollution is usually thought of as smoke from large factories or exhaust from vehicles, air pollution can come from indoors also. Burning kerosene, wood, or coal to heat a house can contaminate the air inside the house, resulting in air pollution indoors. The ash and smoke from the burning of the substances can make breathing difficult and can also stick to the walls, food or......

...affected by air pollution. People exploit billions of tons of coal, petroleum, gas and expel into the environment a large amount of toxic waste annually. Nobody all over the world wants to breathe in such dirty atmosphere. However, it is very difficult to find a place which is not polluted. This essay will argue that governments around the world need to spend more money on ways to purify the air in order to reduce air pollution’s negative effects on the human life and biodiversity. One of the main reasons why it can be argued that governments around the world need to spend more money keeping the air clean is that air pollution has a serious impact on the human life. Air pollution influences people’s health and even can kill many living organisms including humans. For example, in recent years, people release into the atmosphere toxic gas such as CO2, NOX, CH4 and CFC causing the greenhouse effect. If people do not take effective measures to reduce greenhouse gas emission, global temperature will raise from 1.8 to 6.4 °C in 2100. Besides, according to WHO, the global warming will be likely to cause more than 150,000 deaths and 5 million people are infected with various diseases. The above figures could increase twice in 2030. For this reason, protecting the air is an urgent issue that needs doing right now. Another reason why governments around the world need to concentrate on protecting the air is that air pollution has negatively affected biodiversity. Air pollution can......

This article examines how we cause air pollution, the amount we emit, and the effects our emissions have on human health, the environment, and the economy. Something that this article says that I have never thought of before is that we cause air pollution directly and indirectly. Solid facts are given as to how much pollution is emitted annually by families and by individuals as well. This source gives an in depth analysis on the types and sources of pollutants and the effects of these pollutants on human health, the environment, and the economy. This source provides a solid base for my paper and my other sources by providing background information to the multiple aspects of air pollution that I need to know. It provides information as to how the main cause of air pollution is actually caused indirectly by us through the goods and services we buy. “Most of this air pollution we cause results from the burning of fossil fuels, such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles” (Air Pollution). This source provides a pie chart to help readers visualize the sources of air pollution that we emit daily. It very clearly describes the pollutants such as: ozone, nitrogen oxides, carbon monoxide, volatile organic compounds, particulate matter, sulfur dioxide, lead, and mercury. It goes on to provide the sources......

... Beijing Air Pollution Beijing has suffered from serious air pollution for many years. The Chinese Capital has issued its first pollution red alert as the capital became notoriously polluted and enveloped by a wave of acrid smog for the second time in December 2015. Much of the blame for Beijing’s air pollution will be its burgeoning automobile industry producing 24 million vehicles every year (Jack, 2016). Although this served as a capital booming development, the increase in vehicle population has also led to practical problems like traffic congestions. It causes a decrease in average car speed, which in tend increase the total emission from the vehicle exhaust (Tao Yang, 2009). PM2.5, which was said to be the smallest and deadliest smog particles emitted from vehicles’ exhaust, can rise to as high as 500 micrograms per cubic meter in some parts of Beijing. This is 20 times the level that is considered safe by the World Health Organisation. The rising use of automobiles has become an issue of environmental sustainability as the pollutants given off by the vehicles’ exhaust affects the cleanliness of the air in Beijing. This in turns cause the quality of the environment that the people are living in to deteriorate. It has put public health at risk everyday because of the presence of PM 2.5 particles in the air (Katrina, 2016). When inhaled, it can contribute to a myriad health issues like respiratory and cardiovascular problems, and even increase the risk of cancer......

...Air pollution There are many different types of air pollution that effect’s us on an everyday basis. I never realized how many different kinds of air pollution until I have read this chapter. Humans are the main cause of air pollution. The sad part is we continue to pollute. We poison the air every day by throwing out enormous piles of garbage, burning tons of fossil fuels, and driving. Primary pollutants are suspended particle matter, radon, lead, air toxics, carbon monoxide, sulfur dioxide, nitrogen oxides and volatile organic compounds. The secondary pollutants are ozone and peroxyacetyl nitrates (Environmental Science 11e). These are mixed in with multiple air pollutions. Air pollution is caused by a brown cloud that hangs over the valleys, especially on hot days. That is caused by the ozone. The ozone is a colorless gas that is in the air. When the ozone gets closer to the earth’s surface it is called ground zero. At that point it is very harmful. It is very harmful to the plants, animals and is very highly reactive in the lungs and can cause respiratory disease too. The ozone can cause choking, coughing and stinging eyes. Ground zero chemicals are created by automobiles, trucks, and buses; large industry; utility companies; gas stations; print shops; paint stores; cleaners; and off-road equipment, such as aircraft, locomotives, construction equipment, and lawn and garden equipment (Environmental Science 11e). Also to reduce the risk of this is to......
