After cleanest month since 2015, Capital’s air begins downward slide into long winter
New Delhi: After a month in which Delhi saw its cleanest air in five years, air pollution has seen an uptick in the national capital over the past few weeks. With monsoon drawing to a close and little possibility of more rainfall this month, the air quality may deteriorate further by the end of this month, scientists at the India Meteorological Department (IMD) said.
