Mumbai’s skyline has been reeling beneath a thick blanket of smoke for greater than every week now. Whereas the Central Air pollution Management Board’s (CPCB) dashboard has proven the town’s general air high quality index (AQI) hovering across the ‘average’ class, a detailed look into the CPCB’s localised knowledge has proven that Mumbai’s AQI in a number of pockets has been worse than what it was final 12 months.
On December 27 (Friday), Mumbai’s common AQI stood at 151 ug/m3, which is considered ‘average’. Nevertheless, pockets like Mazgaon, Borivali, Malad, and Navy Nagar continued to document ‘poor’ AQI readings, above 200 ug/m3.
In line with the CPCB, AQI readings between 0-50 are considered good, 51-100 passable, 101-200 average, 201-300 poor, 301-400 very poor and above 400 extreme.
The CPCB’s knowledge reveals that the variety of days these pockets have recorded ‘poor’ AQI this 12 months is far more than final 12 months.
For instance, in December thus far, Worli has recorded seven days of poor and in the future of ‘very poor’ AQI, whereas in the identical month final 12 months, Worli didn’t see a single day of unhealthy air and continued to document AQI beneath the ‘passable’ and ‘average’ classes.
Equally, Mazgaon recorded 11 days of poor AQI thus far in December this 12 months whereas it didn’t have a single day of unhealthy air in the identical month final 12 months.
Deonar within the jap suburbs, which homes the Deonar landfill, recorded three days of poor AQI final December. This December, it recorded eight days of poor AQI.
South Mumbai’s Navy Nagar, which recorded 12 days of ‘poor’ AQI in December final 12 months, noticed 14 days of ‘poor’ and 6 days of ‘very poor’ AQI this December.
Malad within the western suburbs, which noticed 9 days of ‘poor’ AQI final December recorded 10 days of ‘poor’ AQI and a day of ‘very poor’ AQI this 12 months.
Gufran Beig, chair-professor of Nationwide Institute of Advance Sciences (NIAS), instructed The Indian Categorical that at current, a cyclonic circulation has developed over north India, which is coinciding with western disturbances.
“On account of this, moisture has been getting into inside Mumbai’s ambiance, making the air heavy as a result of presence of PM 2.5 particles, which is resulting in formation of a haze, which is lowering visibility. In all probability, the layer of haze that has been fashioned is sitting fairly greater from the bottom, the place the monitoring stations are positioned. Consequently, the precise readings couldn’t be learn within the system,” mentioned Beig.
“Moreover the weather conditions, man-made components like vehicular emission and development works are additionally contributing to the worsening air high quality,” he added.
Current framework insufficient
At present, Mumbai has 25 AQI monitoring stations operated by the Brihanmumbai Municipal Company (BMC), the Maharashtra Air pollution Management Board (MPCB) and the Indian Institute of Tropical Meteorology (IITM). Many of those stations document ‘poor’ to ‘very poor’ AQI each day, whereas the town’s general AQI studying stands within the average class.
Bhagwan Kesbhat, founding father of NGO Waatavaran, mentioned the present framework that has been utilized by the administration to watch Mumbai’s AQI is insufficient. He mentioned the present variety of monitoring stations will not be satisfactory in terms of the demography of Mumbai.
“The expertise that the authorities are utilizing isn’t satisfactory to guage the general state of affairs in Mumbai. Consequently, the distinction between the localised knowledge and Mumbai’s common knowledge is startling. On the native degree, components corresponding to development works, rubbish burning might result in a dip in AQI. Since these actions are going down outdoors the vary of the monitoring stations, the precise air high quality of numerous areas stays unassessed. Subsequently, the authorities ought to contemplate establishing a way more hyperlocal measuring system,” added Kesbhat.
Regardless of makes an attempt made by The Indian Categorical, S V Parkale, deputy municipal commissioner (atmosphere), didn’t remark.
In the meantime, the BMC mentioned in an announcement that previously 24 hours, Rs 52,000 has been collected as penalty from those that have been violating mud mitigation norms. The BMC’s figures additionally confirmed {that a} complete of 129 roads or 248km of Mumbai’s street size had been sprinkled with water.
“Actions like water sprinkling and taking motion in opposition to mud mitigation norms aren’t going to assist. The commercial emissions which are going down within the Mumbai Metropolitan Area (MMR) are additionally contributing to poor AQI for the reason that air-shed is widespread. Subsequently, far more intervention is required from the authorities,” Kesbhat mentioned.
