Question

short note on smog with delhi incident..

Answer 1

Smog is a mixture of fog and smoke particles, especially dust and Particulate Matter [PM]. Fog is water droplets suspended in the atmosphere. It requires low temeprature. When there is a lot of PM and dust in air, water droplets get a nucleus for condensation. Thus, water droplets condense on PM, leading to smog.
In Delhi, PM had been very high due to burning of agriculture residue in neighbouring states such as Punjab, Haryana and Uttar Pradesh. Also, due to lower temperatures, PM remained in the lower layers of atmosphere, resulting in smog. PM from vehicles and automobiles had also contributed to smog. It greatly increased pollution levels in Delhi-NCR. People had respiratory problems, Their eyes were irritating due to pollutants.
