GRAP Stage 1 Activated:
The deterioration had prompted the Commission for Air Quality Management (CAQM) to invoke Stage 1 of the Graded Response Action Plan (GRAP) across Delhi-NCR on October 21 to curb air pollution.
Under GRAP-1, the use of coal and firewood is banned in tandoors at hotels, restaurants, and open-air eateries, and diesel generator usage is restricted to essential or emergency purposes.Visuals from the Kalindi Kunj area depicted massive blankets of toxic white foam floating across the water’s surface, highlighting persistent pollution challenges in the river.
A Noida-based environmental activist, Manoj Kumar, has said that weather conditions play an important role as well“During October and November, lower wind speeds and changes in temperature can trap pollutants close to the ground, making the air more harmful to breatheFirecrackers during festivals can add to the pollution loadThe exact contribution of each source varies with the season and weather,” he said to The New Indian Express.
PM2.5 and PM10 are common indicators of particulate pollutionSources include vehicle exhaust, road dust, construction activity, industrial emissions and the burning of fuelsWeather conditions, including wind speed and atmospheric mixing, influence how quickly these pollutants disperse.
