Sprinklers at Delhi Monitoring Stations Spark Air Quality Concerns
Water sprinklers are being used near air quality monitoring stations in Delhi.
Some people think this is done to make the air look cleaner than it is, possibly for political reasons.
The water helps to remove dust and pollution by making the heavy particles fall to the ground.
Others say the drop in pollution levels is also due to the temperature getting warmer.
The PM2.5 and PM10 levels dropped at the Anand Vihar and R.K. Puram monitoring stations after the water was sprayed.
Water sprinklers were observed operating near Delhi air quality monitoring stations.
Aam Aadmi Party alleged sprinklers artificially lower AQI readings.
BJP dismissed the allegation as politically motivated.
PM2.5 and PM10 levels decreased at Anand Vihar and R.K. Puram stations during sprinkling.
Experts suggest sprinklers can cause a temporary reduction in readings.
