Air Pollution

Geography 110-70Fall 2015Presentation by:Leticia Villaseñor

Air Pollution-What is it? Air pollution is the presence in

or introduction of contaminate substances that are found in the atmosphere which are harmful to all life forms and our planet. Some contaminates are photochemical smog, smoke from wildfires, ash from volcanic eruptions, windblown dust, pollen from plants, salts particles from breaking ocean waves, internal combustion engines, and industry. As air pollutants manifest into the air it reduces visibility due to the fine particulate matter and associated water droplets.

Air pollution consists of primary and secondary pollutants.Primary pollutants are

contaminates released directly into the air such as particulates, sulfur compounds, nitrogen compounds, carbon oxides, and hydrocarbons.

Secondary pollutants are photochemical smog. They are not released directly into the air, but are the result of chemical reactions or other processes in the atmosphere.

Where is Air Pollution happening? Air pollution is located

throughout the world, but is mainly concentrated in urban areas.

Highly populated and high industrial areas have higher

amounts of air pollution. For example, Asia has a high level of air pollution. Los Angeles, California and Pittsburg, Pennsylvania both have excessive amounts of air pollution. Additionally, the rising levels of air pollution has brought a new disease-the Beijing cough.

Effects of Air PollutionHuman health Environmental

How is life on Earth affected by Air Pollution?All forms of life are

affected by air pollution. Air pollution affects human health. It can cause lung malfunction and cardiovascular disease. Certain contaminates also found in the atmosphere contribute to acid rain and damage to the ozone layer. This causes damage to plant life like food crops and trees. It can also cause skin cancer in humans.

Air Pollution has impacted our atmosphere since the Roman Empire. Methane gas was produced from the Roman domesticated livestock such as cows, sheep, and goats. As the Han Dynasty in China expanded its rice fields, they harbored methane producing bacteria. Also, blacksmiths in both empires produced methane gas when they burned wood to make their metal weapons. With the beginning of the Industrial Revolution in the 1700’s, pollution became more widespread and intense. By the twentieth century, air pollution caused many deaths. Including 63 people killed over a five-day period in Belgium’s Meuse Valley in 1930; 6,000 illnesses and 20 deaths in Donora, Pennsylvania, during a five day period. Due to being enveloped in a lethal haze, residents experienced severe respiratory and cardiovascular problems. This was a harsh consequence of industrial growth. Also, in 1952, London, England, a thick deadly pollution called “The Great Smog of London”, killed an estimated 4,000 people. This was caused by people burning coal in home fires and coal-fired power plants.

From late December 2001 to early January 2002, smog obscured the south-east coast of China. Most of this area was covered by a thick grayish shroud of aerosol pollution. The smog was so thick it was difficult to see the surface in some regions.

Is there some problem or issue with Air Pollution?Air pollution is one of the world’s biggest killers. It causes around two million people to die prematurely each year. For example, in the United States around 41,000 people a year are estimated to die early because of air pollution. Air pollution is worse in developing countries due to inadequate legislative laws . There has been an increase in emission standards imposed by the EPA. However, in the United States there has been less emissions of pollutants with the exception of ozone. Air pollution is a global issue. In order to control the growth of air pollution, all countries must act accordingly to create a unified standard for emissions.

What are some solutions of Air Pollution? In order to help reduce air pollution there needs to be a change in the type of energy sources used. Renewable energy like wind and tides should be used instead of fossil fuels such as coal and oil. Other alternatives could be bio-fuels, nuclear power, hydroelectric power, and solar power. Presently, not all alternative energy sources are economically feasible. However, with research on a global level new alternatives could be created. All efforts need to be taken to reduce air pollution for the future of all human, animal and plant life on Earth.

Use public transportation and/ or car pool Conserve energy Reduce, Reuse and Recycle Use clean energy resources such as solar,

wind and geothermal Use energy efficient devices such as CFL light Use electric vehicles
