Problems Caused By Air Pollution Some people think that air pollution is non harming the Earth or the people, but it is making worse, by killing the Earth and acquiring people ill. Air pollution non merely threatens the wellness and life of worlds but besides causes harm to the environment Gay First, air pollution causes a great trade of wellness jobs.

One of many forms of pollution, air pollution occurs inside homes, schools, and offices; in cities; across continents; and even globally.
Air pollution makes people sick, it causes breathing problems and promotes cancer, and it harms plants, animals, and the ecosystems in which they live. Some air pollutants return to earth in the form of acid rain and snow, which corrode statues and buildings, damage crops and forests, and make lakes and streams unsuitable for fish and other plant and animal life.
At the same time, our polluted atmosphere is becoming a better insulator, preventing heat from escaping back into space and leading to a rise in global average temperatures.
Scientists predict that the temperature increase, referred to as global warming, will affect world food supply, alter sea level, make weather more extreme, and increase the spread of tropical disease.
Most air pollution comes from one human activity: Among the harmful chemical compounds this burning puts into the atmosphere are carbon dioxide, carbon monoxide, nitrogen oxides, sulfur dioxide, and tiny solid particles including lead from gasoline additives called particulates.
Between andmotor vehicle use rapidly expanded, and emissions of nitrogen oxides, some of the most damaging pollutants in vehicle exhaust, increased percent. When fuels are incompletely burned, various chemicals called volatile organic chemicals also enter the air.
Pollutants also come from other sources. For instance, decomposing garbage in landfills and solid waste disposal sites emits methane gas, Air of donora essay many household products give off Volatile organic chemicals.
Some of these pollutants also come from natural sources. For example, forest fires emit particulates and Volatile organic chemicals into the atmosphere. Ultrafine dust particles, dislodged by soil erosion when water and weather loosen layers of soil, increase airborne particulate levels.
Volcanoes spew out sulfur dioxide and large amounts of pulverized lava rock known as volcanic ash. The eruption of Mount Pinatoubo in the Philippines, for example, dumped enough volcanic ash into the upper atmosphere to lower global temperatures for the next two years.
Unlike pollutants from human activity, however, naturally occurring pollutants tend to remain in the atmosphere for a short time and do not lead to permanent atmospheric change.
Once in the atmosphere, pollutants often undergo chemical reactions that produce additional harmful compounds. Air pollution is subject to weather patterns that can trap it in valleys or blow it across the globe to damage pristine environments far from the original sources.
The troposphere is the region in which most weather occurs. If the load of pollutants added to the troposphere were equally distributed, the pollutants would be spread over vast areas and the air pollution might almost escape our notice.
Pollution sources tend to be concentrated, however, especially in cities. In the weather phenomenon known as thermal inversion, a layer of cooler air is trapped near the ground by a layer of warmer air above. When this occurs, normal air mixing almost ceases and pollutants are trapped in the lower layer.
Local topography, or the shape of the land, can worsen this effect, an area ringed by mountains, for example, can become a pollution trap. Smog is intense local pollution usually trapped by a thermal inversion. Before the age of the automobile, most smog came from burning coal and was so severe that in 19th-century London, street lights were turned on by noon because soot and smog darkened the midday sky.
Burning gasoline in motor vehicles is the main source of smog in most regions today. Powered by sunlight, oxides of nitrogen and volatile organic compounds react in the atmosphere to produce photochemical smog.
Smog contains ozone, a form of oxygen gas made up of molecules with three oxygen atoms rather than the normal two.
Ozone in the lower atmosphere is a poison; it damages vegetation, kills trees, irritates lung tissues, and attacks rubber. Environmental officials measure ozone to determine the severity of smog.
When the ozone level is high, other pollutants, including carbon monoxide, are usually present at high levels as well.
In the presence of atmospheric moisture, sulfur dioxide and oxides of nitrogen turn into droplets of pure acid floating in smog. These airborne acids are bad for the lungs and attack anything made of limestone, marble, or metal.
In cities around the world, smog acids are eroding precious artifacts, including the Parthenon temple in Athens, Greece, and the Taj Mahal in Agra, India. Oxides of nitrogen and sulfur dioxide pollute places far from the points where they are released into the air.
Carried by winds in the troposphere, they can reach distant regions where they descend in acid form, usually as rain or snow. Such acid precipitation can burn the leaves of plants and make lakes too acidic to support fish and other living things. Because of acidification, sensitive species such as the popular brook trout can no longer survive in many lakes and streams in the eastern United States.
Smog spoils views and makes outdoor activity unpleasant.34 air pollution causes essay examples from academic writing service EliteEssayWriters™.

Air pollution . Corporate Office Power & Industrial Services. 95 Washington Street, P.O. Box Donora, PA Fax [email protected] Pollution is the introduction of contaminants into the natural environment that cause adverse change.
Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring rutadeltambor.comion is often classed as point source or nonpoint source pollution.
Air Pollution Then the sky turned red, toxins over head, everybodies dead, everybodies dead. (GutterMouth; Nitro Records; ) In , the industrial town of Donora, Pennsylvania suffered 28 deaths because of the thick smog.
Professional chemists will be m ore precise and say that fluorine is the most “electronegative” element, meaning that it is the most aggressive electron “thief,” because the alkali metals are the most “electropositive” elements, meaning their affinity to “give away” an electron, and electronegativity and electropositivity are not easy to compare, as far as “reactivity” goes.
