during lockdown due to covid 19 (maximum 2 pages)

Explanation:
The coronavirus pandemic has lead to an increase in air quality all around the world. Lockdowns have resulted in factories and roads shutting, thus reducing emissions.
Every winter, New Delhi and other big cities in the north are enveloped in a blanket of smog as farmers burn crop residue. The air tends to clear a little in spring.
However, in the first few months of this year, India experienced a significant decline in some pollutants. The lockdown imposed by Prime Minister Narendra Modi on the country’s 1.3 billion people could be a major contributing factor. However, there may also be other factors impacting air quality, according to Pallavi Pant, an air quality scientist at the Health Effects Institute in Boston.
“Air pollution levels are often influenced by local meteorology, like temperature or wind speed. Several early analyses are showing declines in air pollution in regions where shutdowns have taken place. However, any such analyses should consider all relevant factors.” Pallavi Pant told Reuters.
Ground stations in northern India also show a downward trend in overall PM2.5, according to data from local authorities.
Beyond improvements in outdoor air quality, scientists are also curious how lockdowns have affected indoor air quality, with millions of people staying at home for far longer than usual.
“As we continue to talk about improvements in outdoor air quality, people are spending a lot more time indoors and the exposure patterns for indoor air pollution might be different at this time too,” said Pant.
