Delhi-NCR air quality deteriorating, GRAP stage III curbs to continue: CAQM

The Centre's air quality panel on Friday said curbs under stage 3 of the Graded Response Action Plan (GRAP) will continue in Delhi-NCR as the air pollution in the region is showing an upward trend. Delhi's 24-hour average air quality index stood at 346 at 4 pm on Friday, deteriorating from 295 on Thursday. "The Air Quality Index (AQI) has been showing an increasing trend for the last two days in Delhi-NCR.

Considering the need to continue with the steps to prevent deterioration of air quality, the sub-committee on Graded Response Action Plan (GRAP) has decided that the "ongoing action implemented under Stage III of GRAP shall continue and it should not be withdrawn at this stage". All construction and demolition work, except for essential projects, is banned in Delhi-NCR under the third stage of the GRAP. Brick kilns, hot mix plants

WHO has also cautioned vulnerable groups like pregnant women, older adults above 60 years, and children under 5 years about the risks and health effects that poor air quality can cause.
