On 19th December, Delhi NCR (National Capital Region) marks a slight improvement in its air quality index. The status of the air quality index (AQI) shifts from “very poor” to “poor”.
According to the System of Air Quality and Weather Forecasting And Research (SAFER),
the total current air quality index (AQI)stands at 290.
The PM concentrations of 2.5 stood at 117 comes under the “poor” category and PM concentrations of 10 stood at 193 comes under the “moderate” category.
Meanwhile, the air quality index in areas of Guru gram and Noida still comes under “very poor” and “poor” categories respectively.
On Sunday morning the air quality index in Noida stands at 283 while in Guru gram it stands at 308 as reported by officials.
According to the government agencies, the AQI between 0 and 50 is considered as “good”, 51 to 100 is “satisfactory”, 101 to 200 is “moderate”, 201 to 300 is “poor”, 301 to 400 is “very poor” and 401 to 500 is “severe”.
After seeing an improvement in the AQI of Delhi though schools from classes 6th onwards were reopened by the Delhi government on Saturday, the construction activities are still exempted till further orders by the Delhi Government.
Earlier this week the Delhi government is worried about the hazardous impact of poor air quality in the national capital had banned the construction process, had closed schools as well as banned the entry of trucks in the national capital.
The Commission for Air Quality Management (CAQM) has allowed a few projects of railways, airports, interstate bus terminals and healthcare facilities of national importance due to the toxic air quality. Few other projects involve hospitals, nursing homes, linear public projects like highways, flyovers, over bridges though they are exempted but still have to strictly abide by the directions issued by the commission.
Taking into consideration different studies that clearly show that construction and demolition sites are a major contributor to air pollution across the NCR, the commission is of the view that except for the above-said exemptions, construction and demolition activities should not be allowed in the NCR till further orders," the panel said in official order.
” While the Commission's restrictions are still in force to control air pollution from two other major sectors contributing to air pollution namely industries and transport, it is both advisable and desirable to follow a phased approach in respect of the construction sector also considering the air quality in NCR," the CAQM order said.
Every year around November the AQI increases at a rapid rate, leading to poor air quality. The poor AQI in Delhi causes extreme breathing problems among the children and elderly.
