...Urban air pollution has been growing since the Industrial Revolution largely as a result of rapid industrialization, burgeoning cities, and greater dependence on fossil fuels which have brought in their trail increased production of harmful pollutants, making life in many cities increasingly unpleasant and unhealthy. Among the most common and most virulent of air pollutants are sulphur dioxide, suspended particular matter (SPM), nitrogen oxides, carbon monoxide, and lead. There is also evidence of a growing threat to human health from indoor pollutants such as radon, formaldehyde, asbestos, mercury and organic substances. Many industrialized countries have succeeded in controlling and reducing the most toxic pollutants, but in several others, e.g., less industrialized Western countries and many developing countries the problems continue. In many developing countries, urban air pollution is worsening. Urban air pollution Image Source: klimasnakk.files.wordpress.com Rapidly growing cities, more traffic on roads, use of dirtier fuels, reliance on outdated industrial processes, growing energy consumption, and the lack of industrial zoning and environmental regulations are continuing to contribute to falling urban air quality and deteriorating public health. Much of the world’s population lives in cities where pollution levels exceed recommended WHO guidelines, thereby exposing inhabitants to substantial health threats. More than 1200 million people may be exposed...

...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 clothing...

...INTRODUCTION 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 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. In this essay I will try to explain what pollutants are and how they affect 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 understand 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 automobiles, much still remains. Particulate matter (soot...

...Doctors AIR POLLUTION IN KARACHI ITS CAUSES AND EFFECTS ON HUMAN HEALTH Prof. Dr. Gheyas Uddin Siddique* Dr. Muhammad Nadeem-ullah** ABSTRACT Air Pollution is one of the main problems of urban area of our society. Air pollution occurs when so many contaminants are released by the industries and motor vehicles. Karachi is one of the top 10 cities of the world which has the highest level of pollutants packed into the air. Air pollution is affecting the health of common men. People often suffer in respiratory diseases like asthma, lungs diseases and cancer etc. It has become a serious health hazard for Karachiites. In the present research paper, the researcher has tried to explore causes of air pollution and its effects on human health. It has been observed that the number of private vehicles is increasing day-by-day due to lack of good public transport facilities. The roads are not broad enough to allow this big number of vehicles run comfortably. In near future there is no hope for extension of roads so on the basis of findings some recommendations are made, and by implementations of those the effects of air pollution can be minimized. But sincerity and commitment is required for it. Key Words: Air Pollution, Vehicles, Health, Karachi Introduction We know that the health of a common person of urban areas, particularly of Karachi is not satisfactory. Due to one or other reason 95% people are suffering various diseases. Apart from other reasons, one of the main causes is air...

...I'm interested in the air pollution problem in Los Angeles, CA, because I used to live ther and they have a lot of problems caused by air pollution. Presently, there are many other environmental problems in the world, for example, global warming, desertification, ozone depletion, etc. Air pollution however, remains as one of the biggest environmental problems throughout the world. It can be the cause of disease like cancer or environmental problems like global warming. Actually, human products, from factories, vehicles and buildings, produce exhaust fumes and also produce microscopic particles which are known causes of diseases like cancer, heart disease, pneumonia and premature death (Danelski, 2006). We have to consider the air pollutants, and we need to improve the emission control systems of factories that emit the gas that produces air pollution to solve the problem. According to Gwen Williams, an exponent of Muskegon Family Care, patients who develop respiratory disease are really high around these factories, not only the people who live near the factories but also the people who live far from the factories (Prichard, 2005). This is proof that the gas of air pollutant is easily spread. Nowadays, our air has become polluted as we have developed our technologies to make our lives more convenient. Surely, living standards of our lives have improved and are much better than during the past. However, the environment has been certainly destroyed with these improvements. Therefore...

...An inversion is "A reversal of the normal decrease of air temperature with altitude, or of water temperature with depth," claims Google. In an easier way to understand it, an inversion is air pollution. Air pollution is dangerous and deadly, the damage depends on any asthma related problems. Not just asthma, also breathing problems. Air pollution is air with thick and deadly things like oil in it. It is caused by factory like buildings that liberate lethal chemicals that combine with the air. There are many reasons why it is caused, what it does, and some solutions. Bad air, also known as air pollution can hurt people. But terrible air pollution can kill people.

...Air Pollution Air pollution is one of the major problems we have today. A lot of the people have to suffer from air pollution, which affects people’s health and life. Air pollution can affect people chemically, physically and mentally. Air pollution is basically when air comes together with some harmful gases. A lot of chemical factories and power plants released chemical gases into air and air becomes polluted. Air pollution is also harmful to animals and their habits. Air pollution causes asthma, skin cancer and acid rain Firstly, air pollution contributes to asthma. A lot of people suffered from this disease. Asthma is chronic inflammatory disease. Some air pollutants lead to asthma where chemicals in our bodies make the muscles constrict and effects the skin pores for airways. It makes the airways very small and can cause coughing, wheezing and general breathing problems. Asthma is one of the major diseases in the world. Secondly, skin cancer occurs due to the ultra violet radiation from the sun. The pollutant air is known as chlorofluorocarbons (CFC) do major damaged to our environment. The CFC combines with the earth’s upper atmosphere of ozone layer. The ozone layer protects the earth from the ultra violet radiation of the sun. The CFC’s gas molecules transfer and destroy the ozone layer and cause the skin cancer. So, skin cancer is another disease contributed to air pollution. Thirdly, air pollution also causes acid rain on the environment. Factories, power plants...

...about 20,000 liters of air. Every time we breathe, we risk inhaling dangerous chemicals that have found their way into the air. Air pollution includes all contaminants found in the atmosphere. These dangerous substances can be either in the form of gases or particles. Air pollution can be found both outdoors and indoors. Pollutants can be trapped inside buildings, causing indoor pollution that lasts for a long time. The sources of air pollution are both natural and human-based. As one might expect, humans have been producing increasing amounts of pollution as time has progressed, and they now account for the majority of pollutants released into the air. Air pollution has been a problem throughout history. Even in Ancient Rome people complained about smoke put into the atmosphere. The effects of air pollution are diverse and numerous. Air pollution can have serious consequences for the health of human beings, and also severely affects natural ecosystems. Because it is located in the atmosphere, air pollution is able to travel easily. As a result, air pollution is a global problem and has been the subject of global cooperation and conflict. Some areas now suffer more than others from air pollution. Cities with large numbers of automobiles or those that use great quantities of coal often suffer most severely from problems of air pollution.

...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 reduce...

...AIR & LAND POLLUTION Amy Hubbard Ashley Hicks 3/21/2014 Every year in the U.S. factories release over 3 million tons of toxic chemicals into the land, air and water. This hazardous waste causes us to lose over 15 million acres of land every year, it leads to respiratory complications and other health problems and it makes our rivers and lakes too polluted for us to swim in and drink. But factories are only part of the problem of pollution. Pollution is caused by industrial and commercial waste, agriculture practices, everyday human activities and most notably, modes of transportation. No matter where you go and what you do, there are remnants of pollution. What is pollution? Pollution is the introduction of a contaminant into the environment. It is created mostly by human actions, but can also be a result of natural disasters. Pollution has a detrimental effect on any living organism in an environment, making it virtually impossible to sustain life Here are a few facts about land pollution: Every year one American produces over 3285 pounds of hazardous waste Land pollution causes us to lose 24 billion tons of top soil every year Americans generate 30 billion foam cups, 220 million tires and 1.8 billion disposable diapers every year We throw away enough trash every day to fill 63,000 garbage trucks Every day Americans throw away 1 million bushels of litter out their car window Over 80% of items in landfills can be recycled, but they’re not How to Prevent...

...liters of air. Every time we breathe, we risk inhaling dangerous chemicals that have found their way into the air. We as humans depend on the air around us to live, without it we would die. We rely on this as an essential source for living. Air pollution includes all contaminants found in the atmosphere. It is another major problem that is yet to be solved. These dangerous substances can be either in the form of gases or particles. The air is 99.9% nitrogen, oxygen, water vapor, and inert gases. Air pollution is a common term meaning the dirtying and gradual destruction of our natural resources, especially our air, water and land. This is referred to as environmental pollution. Once, years ago, the air was fresh and clear and the rivers were clean with fish swimming in the crystal clear waters and streams. This is no longer true today. Air pollution is the dirtying of the air. Where once we had blue skies and fresh air to breathe in, this is no longer the case. The air today is choked with toxic fumes from cars and factories. With more and more cars on the road, the carbon monoxide emitted from the car exhausts has polluted the Earth’s atmosphere. The clearing of land to make way for housing or farms has also lead to forests being destroyed and burnt. But did you know that air pollution also found both outdoors and indoors? It can, Pollutants can be trapped inside buildings, causing indoor pollution that lasts for a long time. The effects of air pollution are diverse...
