Centre To Install 1,500 Manual Air Quality Monitoring Systems By 2024

The manually operated air quality monitoring systems were a strange way of calculating air pollution


New Delhi: 

The Centre is aiming to install 300 more realtime ambient air quality monitoring systems across the country by 2024 as the country battles deteriorating air quality.

Apprising about the number of Continuous Ambient Air Quality Monitoring Systems (CAAQMS), a senior official of the Environment Ministry said 150 realtime and 731 manual stations are presently installed in 70 cities across the country, 48 of them in the national capital alone, for accurate and comprehensive evaluation of air quality.

"We aim to increase the realtime monitoring system to 450 and the manual stations to 1,500 before 2024," Satyendra Kumar, deputy secretary, Ministry of Environment, Forests and Climate Change, told PTI.

The official said some installations will be a part of the National Clean Air Programme launched recently to monitor and reduce 20-30 per cent pollution by 2024.

According to the ministry's 2017-18 report, there were 28 CAAQMS in the national capital and 86 realtime CAAQMS in 57 other cities. Twenty additional CAAQMS were proposed to be installed in Delhi.

"We have installed those 20 CAAQMS in Delhi and aim to install more across the country. This system is not a pollution mitigating device but only to evaluate the presence of particles in air and the state of pollution. More the devices, more accurate the data," Mr Kumar said.

However, environment activist and lawyer Gaurav Bansal opposed the view that higher number of devices would help calculate the data as the devices were not taking into consideration many gases present in the air.

"CAAQMS is not giving accurate data as the devices need to be upgraded to take into account several gases before calculating pollutants. Several gases are being left out because of which accuracy is questionable," Mr Bansal said.

He was also of the view that the manually operated air quality monitoring systems were a strange way of calculating air pollution.

The ministry official asserted Delhi has 38 realtime systems and 10 manual stations, making it a total of 48 CAAQMS, which have been giving accurate data on air quality but more number of such devices will help better the evaluation process. The government has identified Delhi's Anand Vihar, ITO, Punjabi Bagh and ISBTs as hotspots.
