Ludhiana: A persistent downpour has delivered a much-needed reprieve to the industrial hub, scrubbing the atmosphere to record the city’s cleanest air quality in more than four months.The Air Quality Index (AQI) plummeted to 55 on Friday following 24 hours of rainfall that began on Thursday night. The reading places the city in the “satisfactory” category, a significant shift for a region that spent 21 days this month grappling with “moderate” air pollution. Data from the Punjab Pollution Control Board (PPCB) shows that Friday’s levels were the lowest recorded since Sept 17, when the AQI hit 49.
A Temporary ReprieveWhile the rainfall washed away suspended particulate matter, experts warn the improvement is likely fleeting. On Thursday, just before the rains arrived, the AQI peaked at a monthly high of 159. “The substantial fall in AQI occurred as rain washed away suspended pollutants,” a PPCB source said. “While this is a temporary improvement, we are focusing on long-term reductions by monitoring industrial emissions, vehicular traffic, and construction dust.“Under “moderate” conditions (AQI 101–200), sensitive groups — including those with lung and heart diseases — often experience breathing discomfort. At Friday’s “satisfactory” level (AQI 51–100), only minor discomfort is expected for highly sensitive individuals. Ludhiana emerged as one of the cleanest major hubs in the state on Friday. Only Rupnagar recorded a superior reading at 45. In contrast, Mandi Gobindgarh and Patiala remained in the moderate zone despite the weather.Calls for Long-Term ActionLocal environmentalists are urging authorities not to rely on the weather to manage public health. Amandeep Bains, a social activist with the Clean and Green Ludhiana campaign, noted that underlying pollution sources remain unchecked. “It is good that the rain has brought down pollution, but this is just a temporary respite,” Bains said. He cited ongoing issues including industrial fuel combustion, the illegal burning of municipal waste, and the seasonal pruning and burning of trees. “For a long-term solution, these activities must be regulated so citizens do not pay for progress with their health.”
