Given below is the representation of type of pollution. Study the picture and answer the question.
(i) Name the type of pollution shown in the picture.
(ii) Name one source of this pollution.
(iii) How does this pollution affect human health?
(iv) Write one measures to reduce this pollution.
(v) State the gaseous compound that leads to the depletion of the ozone layer and create ‘ozone holes’.
(i)
(ii) Main sources of air pollution:
1. Traffic and Mobility:
Pollutants are emitted by the gasoline and diesel engines used in automobiles, ships, railways, and other transportation.
2. Industry and Heating:
The burning of fuels such as coal and petroleum in industrial activities such as power plants, distilleries, and factories emits a wide range of pollutants.
3. Additional Resources:
Not all air pollution is caused by human activity. Because of the diameter of the particles spread, sand and sandstorms from deserts are accountable for pollution.
(iii) Air pollution health impacts on humans:
(iv) Measures to reduce this pollution:
1. Taking public transportation.
2. When not being used, switch off the lights.
3. Recycle and reuse materials.
4. Avoid using plastic bags.
5. Reducing the number of forest fires and smoking.
6. Use fans rather than air conditioners.
(v) CFCs:
The gaseous molecules are known as CFCs, or chlorofluorocarbons, react with the ozone layer, depleting it and causing ozone holes.
Consequences of ozone hole:
