 Hi everyone , recently I have heard about the pollution status in India . Although I am living in Vietnam , I still feel very worry about the air pollution level in India . Because of that , today I decided to write an article about this problem and I hope you will enjoy it . Besides that I also want to send many wishes to India and Indian friends with the hope of seeing India ' air improved . Here's my report : According to the US Embassy¡¯s measurements, air in New Delhi reached PM2.5 concentrations of more than 1,200 micrograms per cubic meter, 48 times the guideline value established by the World Health Organization. This is still short of the record set in Shenyang, China, where concentrations topped 1,400 micrograms per cubic meter. n fact, much of the pollution is coming from farms in nearby states of Punjab, Haryana, and Western Uttar Pradesh. With the rice harvest over, farmers are burning crop stubble — specifically the remnants of the rice crop to prepare the fields to plant wheat and return nutrients to the soil. But what¡¯s unique about Delhi¡¯s smog is that the smoke from the burning outside the city is mixing with pollution inside the city — from construction, vehicles, and fires the poor use to cook and keep warm. This mix of rural and urban pollution intensifies in the cooler winter months and this year¡¯s air currents through the region have been unusually slow, allowing the dirty air to linger. North India¡¯s topography also acts as a basin that traps pollution — making it impossible for the millions of people in the region to escape the toxic air. It¡¯s why there are now reports of reverse migration: People retreating from Delhi to rural areas outside the pollution zone so they can breathe cleaner air.
