inflammation of the lungs and permanent lung damage, reduced oxygen in the lungs due to a elevated levels of carbon monoxide and an increased risk of cancer
. Children may become more susceptible to disease.
How is smog formed how does it affect human health class 9?
General Science
A thick fog like layer envelopes the atmosphere. This layer is made up of smoke and fog. Smoke contains oxides of nitrogen which combine with other air pollutants and fog to form smog.
It leads to diseases relating to lungs like asthama etc.

What is photochemical smog and how it is affecting the lives of human beings?
Photochemical smog is
formed when sunlight interacts with certain chemicals in the atmosphere
. Ozone is the main component in this type of air pollution. Ozone in the stratosphere protects us against harmful ultraviolet radiation, but on the ground, it is hazardous to human health.
What type of reaction creates smog?
Smog is formed when
sunlight interacts with hydrocarbons and nitrogen oxides released into the air by cars and power plants
. A highly reactive compound of oxygen and hydrogen called a hydroxyl radical kick starts that reaction. Sinha’s paper focuses on this hydroxyl radical, known as OH.
What is smog Class 9 short answer?
What is smog? Answer:
The suspended particles like unburnt carbon particles and hydrocarbons mix with smoke and fog in the atmosphere, especially in the cold weather to form smog which results in a lowered visibility
