Photochemical smog- unburned hydrocarbons and nitrogen oxides from power plants and automobiles react with sunlight to form secondary pollutants: ozone, formaldehyde, PAN. Ozone erodes rubber, irritates the respiratory system and damages plants.…
Air pollution is dangerous in the world, and it is mainly caused by fossil fuel emissions…
Air pollution is the initiation of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or damages the natural environment into the atmosphere. Air pollution occurs when the air contains gases, fumes, dust, or other harmful agents. According to Morgan (2003), air pollution was not a problem until the 19th century and Industrial Revolution because pollution was readily diluted in the atmosphere (Morgan, Environmental Health, 2003, p. 247). Air pollution occurs in many forms but can generally be thought of as gaseous and particulate contaminants that are present in the earth 's atmosphere (Air Pollution - Its Nature, Sources, and Effects, 2013). Natural sources of air pollution include forest fires, dust storms, and volcanic eruptions (Morgan, Environmental Health, 2003, p. 249).…
Air pollution affects everything from agriculture and ecosystems to human health, on a global scale. The five major air pollutants are ground-level ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide (Donnatelle, 2010). A majority of these pollutants are the result of human action. One example being coal power plants. These plants release greenhouse gas emissions and particle air pollution. The burning of the coal creates pollutant byproducts. Other forms of industrial pollution, exhaust fumes, burning wood, and several forms of indoor air pollutants result in air contamination. The combination of various air contaminates can be extremely toxic. The pollutants irritate the lungs and may even cause respiratory diseases and cancer in humans (Donnatelle, 2010).…
The atmosphere is a complex dynamic 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.…
Air pollution is one of the main threats to the environment. Burning fossil fuels such as coal, gasoline, and fuel oil releases lead, cadmium, acid gases and contaminants into the atmosphere. These emissions can travel a long distance through the upper atmosphere. Nitrous oxide which is caused by fossil fuel combustion falls back to Earth a nitrous acid. Air pollution also affects animals and plant life. Minimizing the reliance on fossil fuels and using mass transportation system can help reduce air pollution.…
In cities, the largest source air of pollution comes from burning fossil fuels. Cars, heavy duty trucks, trains, airplanes, shipping vessels all burn a large amount of fossil fuels to work. Emissions from vehicles contain many pollutants. Dangerous gases such as carbon monoxide and oxides of nitrogen which are released by vehicles may cause great harm to people. It can cause irritation of the throat, nose and eyes. It can also cause breathing problems such as asthma and bronchitis.…
According to the Oxford Dictionary, air pollution is defined as, “the presence in, or introduction into, the air of a substance which has harmful or poisonous effects.” When an individual thinks of air pollution, chances are they typically imagine a dark smog hanging over an urban area, causing problems such as asthma and other respiratory problems for those who have no choice but to breathe in the air. However, there are several different types of air pollution, some of which are actually invisible to the naked eye. Some air pollutants are responsible for global warming such as carbon dioxide, methane, chlorofluorocarbons, and sulfur dioxide, just to name a few. According to a National Geographic article dated November 8th, 2013, air pollutants have been found to cause lung cancer, which has even happened to an eight year old child in China (Brink 2013). According to an article from Businessweek dated March 27th, 2014, the World Health Organization was able to link 7 million deaths worldwide in 2012 to air pollution alone, making it the “world’s largest single environmental health risk” (Larson 2014). In other words, one out of eight deaths in 2012 were attributed to air pollution (Larson 2014). According to an article from The Guardian, roughly half of Americans (approximately 148 million individuals) are currently living with dangerous levels of air pollution (Goldenberg 2014). Due to the threats that air pollution poses to individuals, or, rather, the Earth and everything living in it as a whole, several states and municipalities have attempted to implement policies reduce air pollution with varying results. This paper will examine the efforts of two regions: New York State and the municipality of Houston, Texas.…
-Smelters (metal refineries) and other metal industries; combustion of leaded gasoline in piston engine aircraft; waste incinerators (waste burners), and battery manufacturing.…
There are lots of sources other than the automobile for air pollution. Nature itself is one of the causes. Sometime nature causes the air pollution by activities like a forest fire, volcanic, hurricane. These are temporary dislocations that nature balances and accommodates to modern economic development, however, sometimes disrupts nature's delicate balance. The other source is from factories. Factories are release smokes and chemical in the air. In many places smoke from factories and cars combines with naturally occurring fog to form smog and create a midday sky. It had happened in London, "London, England, has been subjected to the danger of smog, long recognized as a potential cause of death, especially for elderly persons and those with severe respiratory ailments" (pollution).…
Human activities or anthropogenic sources also cause air pollution. These activities mostly involve burning of fuel.…
1. Burning of Fossil Fuels: Sulfur dioxide emitted from the combustion of fossil fuels like coal, petroleum and other factory combustibles is one the major cause of air pollution. Pollution emitting from vehicles including trucks, jeeps, cars, trains, airplanes cause immense amount of pollution. We rely on them to fulfill our daily basic needs of transportation. But, there overuse is killing our environment as dangerous gases are polluting the environment. Carbon Monoxide caused by improper or incomplete combustion and generally emitted from vehicles is another major pollutant along with Nitrogen Oxides, that is produced from both natural and manmade processes.…
Air pollution is one of the virtual problems nowadays. There are many reasons of it but mostly it is caused by cars, growing cities, development of economy and industrialization. Clean air consists of several gases. When some other gases or dangerous elements get into the clean air, pollution is inevitable. Ozone layer is affected too much by pollution and it will cause serious disturbances on the environment. People are the main cause of pollution because the things that we use contain dangerous chemicals and they make atmosphere dirtier. Furthermore climate changes because of pollution. Many substances involved in the things that people use, pollute the air seriously. For instance, cigarettes contain carbon monoxide. It occurs when wood or petrol are not burned. Another one is carbon dioxide and it emerges when we…
The industry and transportation are the two main sources of air pollution. The main pollutants given off by motor vehicles which affect our health are: carbon monoxide, which is generated by vehicles that use gasoline. The hydrocarbons are formed by other petroleum products. Nitrogen oxides are not a real problem, but on contact with sunlight, they produce toxic compounds that will kill us. Excessive car use and their poor condition contribute to this pollution. Everybody has to pass the annual inspection in order to keep their cars in a good condition and in consequence helps to care our environment.…
There are various locations, activities or factors which are responsible for releasing pollutants into the atmosphere. These…
