Air Pollution

20.000 liters of air is what we breathe on a daily basis. Air is something most people take for granted, you don’t see it around you and breathing goes automatically. But every time we inhale we risk inhaling dangerous chemicals which found their way in our air. Air pollution is the presence of dangerous chemicals in the air that we breathe. It is a change in the air which influences humans health and organism on the planet. Many think that `gases'' pollute the air, those gases go under the names of CFCs, carbon monoxide, and sulfur dioxide. Emissions of carbon monoxide are especially dangerous.

Schematic drawing, causes and effects of air pollution: (1) greenhouse effect, (2) particulate contamination, (3) increased UV radiation, (4) acid rain, (5) increased ozone concentration, (6) increased levels of nitrogen oxides. Source Wikipedia.com

In periods of heavily air pollution there will be no rainfall. The sky will not produce it and the heat will therefore won’t go away. Transport and large industries are always seen as the causes of those pollutants. It is not only bad for humans, plants and animals, it is also said to be harmful for buildings. Buildings become discolored when being disposed for a long time to pollutants. But air pollution is not only a outdoor problem, it occurs indoor as well. Like earlier said is air pollution not only a problem for people’s health but also for earth’s ecosystems. Almost every large city in the world has a poor air quality, Even though Penang is a small city it’s no exception in this list. Air pollution is a problem which goes back in history for a long time, and it’s not something which can be dealt with easily. The first step in reducing air pollution is to understand its causes. While we know the river pollution in Penang is caused by garbage and dirt, the air pollution has many other causes. Industrial fumes and motor vehicles emissions cause the air to be polluted. In order to curb the bad effects of air pollution scientist, governments and environmentalists are testing a variety of methods to help reduce pollution. There are two main types of air pollution control, The first type is input control. Which means to help prevent it before it occurs or trying to limit the effects it will have.

Input control exists of five main types, the first one is that people try to restrict population growth , the second one is to use less energy the next is to improve energy efficiency , the fourth is reducing waste and the fifth is to move to non-polluting renewable forms of energy production .

Then there is output control, the opposite method who seeks to fix the problems caused by air pollution. This involves cleaning up an area that has been damaged by pollution. Input controls are often more effective than output controls. Plus output controls are more expensive, which makes them less desirable to tax payers.

Current air pollution control efforts are not all effective. In the more developed countries, industries often have the money to shift over to methods which decrease air pollution. However, in developing countries and even in countries where pollution is strictly regulated, much more needs to be done and the two main methods are not effective enough. The public plays a huge role in reducing air pollution. Thus a task in any city, land or small village is to stimulate the public acceptance of taking the responsibility and taking actions. The public's willingness to take action. The people who can be considered to pay more money or who are more willing to cooperate are the ones who’s family’s or themselves are personally bothered by the problem. Also they have to have the confidence that the problem can be reduced or in the best way eliminated.

Air Pollutant Index

The department of environment, ministry of natural resources and environment, gives a daily air pollution index for the whole of Malaysia. I have been following the index since...
