Pollution in air is a global phenomena. 9 out of 10 people on earth are breathing polluted air. According to World Health Organisation's World Global Ambient Air Quality Database, 80% of urban people have to face air pollution that exceeds health standards. India has 14 among 15 most polluted cities in terms of PM 2.5 particles. According to WHO Ambient air pollution alone caused some 4.2 million deaths in 2016.
While talking about air pollution, one cannot proceed without mentioning Delhi. Last winter the talk of the nation was pollution and fog in Delhi. Now after sand storms and dust storms Delhi's pollution level crossed the danger mark. The air pollution situation in Delhi remained severe till Saturday. But authorities are hoping that the air quality will improve as the particles are dispersing.
The main reason for air pollution in Delhi is due to massive construction works, huge number of automobiles on road, burning of garbage, and seasonal polluters like burning of field after sugarcane and wheat crops in winters and sand storms and wind blowing with sand from Rajasthan in summers. Pollution sources like factories are emitting toxic gases throughout the year. Air pollution in North India is ubiquitous.
The PM10 level - presence of particles with diameter less than 10 mm had climbed to 778 in Delhi-NCR and 824 in Delhi on Wednesday, demonstrating that severe air pollution is a summertime problem too.
Delhi's Chief Minister Mr.Arvind Kejriwal took some important measures like allowing odd numbers and even numbers of cars in alternative days. But it was not a successful scheme. Union Environment Minister Harsh Vardhan has ordered civic authorities to be on high alert and ensure quality air to the residents. Delhi's Lieutenant Governor Baijal has ordered stoppage of all civil construction works till Sunday. Let us hope that Delhi's pollution problem is solved soon.
