Delhi pollution: 140 air purifiers bought for PM Narendra Modi's office
As pollution choked India's capital Delhi in recent years, a total of 140 air purifiers were purchased for Prime Minister Narendra Modi's offices and at least six other government agencies, according to previously unpublished government data.The purchases came as Modi faced criticism for not taking effective steps to improve air quality in Delhi, one of the world's most polluted cities.Delhi Chief Minister Arvind Kejriwal, who belongs to an opposition party, called the city a "gas chamber" last year as levels of airborne PM 2.5, tiny particulate matter that can reach deep into the lungs, far exceeded levels classified as "hazardous."A British medical journal, The Lancet, has estimated air pollution was responsible for almost 10 percent of the total disease burden in India in 2016.Each year, when pollution levels shoot up in the winter months, the capital's schools are often forced to shut. Last year, all schools in the city were closed for five days.
