Question

Write a report about Air pollution​

Answer 1

Answer:

The main components of the atmosphere are — oxygen (O2) to breath, carbon dioxide (CO2) for photosynthesis, nitrogen (N2) for forming products as ferti­lizers for plants and making the air inert and ozone (O3)-layer against sun rays. Any imbalance in quality of air so as to cause adverse effects on the living organisms is called air pollution.

Air pollution may also be defined as the presence of contaminants which are injurious to human beings, plants and animals (aquatic or terrestrial).

The natural air contains trace amounts (about 1 ppm) of gases like methane (CH4), ammonia (NH3), sulphur dioxide (SO2), hydrogen sulphide (H2S), carbon mono-oxide (CO), hydrogen (H2), argon (< 1 ppm) and variable amounts of dust particles.

Answer 2

Explanation:

Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it's also called smog. Some air pollutants are poisonous.
