UNIT 4. The atmosphere
4.4. AIR POLLUTIONE
YouTube: National Geographic "Air pollution 101"
Quality of air is often deteriorated by substances called air pollutants that affect the health of living things.
| AIR POLLUTANTS | SOURCE | CONSEQUENCES IN LIVING THINGS |
|---|---|---|
| Carbon monoxide (CO) | Motor vehicles and machinery. | Very poisonous. It decreases the ability of the blood to transport oxygen. |
| Sulphur and nitrogen oxides | Burning fuels, especially coal. | Irritant. They produce acid rain that harms plants, animals and monuments. |
| Bad ozone or smog or ground level O3 | Industry, motor vehicles. | Irritant (respiratory problems) and poisonous. It creates a grey cloud, smog, over cities. |
| Soot | Industry, coal heating | It causes serious damage because the tiny particles can pass into the lungs and even into the blood. |

Composición de la atmósfera y contaminantes atmosféricos
HOW TO CARE FOR THE ATMOSPHERE
- Install filters at power stations and factories to prevent the emission of soot and sulphur oxides.
- Use renewable energy (wind, solar.) to gradually replace the use of coal and oil for electricity production.
- Choose responsible energy consumption. Most of the power stations pollute. Reducing energy consumption is another way to reduce pollution.
- Recycle. Using used materials (paper, plastic, glass.) in manufacturing processes causes less pollution than using raw materials.
