Слайды презентации

Слайд 2 Modern smog is a type of

air pollution derived from vehicular emission from internal combustion

engines and industrial fumes that react in the atmosphere with sunlight to form secondary pollutants that also combine with the primary emissions to form photochemical smog.

Слайд 3 Type Of Smog
Photochemical smog
Volcanic smog
Inside our homes
Sulfur Dioxide
From

burning fuel for energy

Слайд 4 Photochemical smog
Photochemical smog is therefore considered

to be a problem of modern industrialization. It is

present in all modern cities, but it is more common in cities with sunny, warm, dry climates and a large number of motor vehicles. Because it travels with the wind, it can affect sparsely populated areas as well.

Слайд 5 Volcanic smog
An erupting volcano

can also emit high levels of sulphur dioxide, creating

volcanic smog, or vog.

Слайд 6 Inside our homes
Some of these pollutants

can be created by indoor activities such as smoking

and cooking

Слайд 7 Sulfur Dioxide
Sulfur is present in all

fossil fuels and is released as Sulfur Dioxide when

the fuels are burned. Sulfur Dioxide reacts with oxygen gas to give Sulfur Trioxide

Слайд 8 From burning fuel for energy
The exhaust

from burning fuels in automobiles, homes, and industries is

a major source of pollution in the air.

Слайд 9 Smog is a serious problem in

many cities and continues to harm human health. Ground-level

ozone, sulfur dioxide, nitrogen dioxide and carbon monoxide are especially harmful for senior citizens, children, and people with heart and lung conditions such as emphysema, bronchitis, and asthma

Health effects

Слайд 10 London
The Great Smog of 1952

darkened the streets of London and killed approximately 4,000

people in the short time of 4 days (a further 8,000 died from its effects in the following weeks and months).

Areas affected

Слайд 11 Mexico City
Within one generation, the

city has changed from being known for some of

the cleanest air of the world into one with some of the worst pollution, with pollutants like nitrogen dioxide being double or even triple international standards.

Слайд 12 Tehran
In December 2005, schools and

public offices had to close in Tehran, Iran and

1600 people were taken to hospital, in a severe smog blamed largely on unfiltered car exhaust.

Слайд 13 United States
A NASA astronaut photograph

of a smog layer over central New York.

Слайд 14 Los Angeles and the San Joaquin Valley

The millions of vehicles in these basins plus

the added effects of the San Francisco Bay and Los Angeles/Long Beach port complexes contribute to further air pollution.

Слайд 15 Southeast Asia
Smog is a regular

problem in Southeast Asia caused by land and forest

fires in Indonesia, especially Sumatra and Kalimantan, although the less political term haze is preferred in describing the problem.

Слайд 16 First, watch a series of animations and movies

First, watch a series of animations and movies depicting the formation

depicting the formation of air pollution.
Then, learn to

understand the Air Quality Index (AQI) in your area.
Next, get familiar with Ozone Action Days and why you should never ignore them
Then, follow the National Air Quality Forecast.
Finally, familiarize yourself with the effects of smog on your health.
