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

Comparing it with Kuala Lumpur of Penang mainland, the island Penang has a pretty good air quality. I have picked a random day and looked up the percentages which apply to Penang. The facts and figures I found on Penang and air pollution show a better image then I would have imagined.

Around 5 P.M
Pulau Pinang Perai 37% of Fine dust
Pulau Pinang Seberang Jaya 2, Perai 43% of Fine dust
Pulau Pinang USM 29% Ozone

The ground ozone which is bad should not be confused with the ozone up in the air which protects us. The good ozone up in the air is also damaging if you don’t protect your body from getting a sunburn. Ozone exists of two different layers in our atmosphere. The one closest to the earth is called the troposphere, this one the ground level or “bad” ozone is a air pollutant. This layer is the main ingredient for urban smog. The troposphere meets its other layer about 9,6 km up, the other layer is called the stratosphere.
The stratosphere layers are warmer higher up and cooler going down, which is in contrast with the troposphere, which is cooler higher up and warmer farther down. The stratosphere is like previous said located between 9,6 km up an 50 km up. The stratospheric also called the "good" ozone protects life on Earth from the sun's harmful ultraviolet (UV) rays. Because ozone has a low water solubility it can easily penetrate in
