Mumbai’s Air Quality Declines with AQI Reaching 160, Experts Cite Smog and Construction

Mumbai, 28th December 2024: Mumbai is grappling with an alarming surge in pollution, with Air Quality Index (AQI) levels soaring beyond typical readings in several areas.

According to the latest updates from the Indian Meteorological Department (IMD), Mumbai is expected to have a cloudy sky on Saturday, with temperatures ranging from a cool 18°C in the morning to a warm 32°C during the day.

The Central Pollution Control Board’s SAMEER app reported the city’s air quality as “moderate,” with an AQI of 160 at 9:05 AM. However, the key question remains: Why has the AQI risen to such levels?

A primary factor in the current pollution crisis is the persistence of smog. Media reports note that a former member of the Maharashtra Pollution Control Board mentioned that smog typically dissipates by 9:30 AM. However, in recent days, it has lingered until 11 AM or later.

Factors Contributing to Mumbai’s Deteriorating Air Quality

Construction Activities
Ongoing construction projects in the city, particularly Metro developments, are believed to be significantly contributing to the city’s poor air quality. Former Municipal Commissioner Iqbal Singh Chahal reported that in 2023, there were about 6,000 active construction sites in Mumbai. Currently, this number has risen to approximately 11,000, not including other infrastructure developments. The R Central ward holds the highest number of sites at 942, followed by K East (933) and K West (815). In addition, large-scale residential projects are underway, including 45 skyscrapers in the central suburbs, 30 towers in the western suburbs, and 59 towers in Thane, with more developments in Navi Mumbai.

Traffic and Vehicle Numbers
Mumbai’s traffic congestion is another major contributor to the city’s pollution levels. With around 1.2 million private vehicles on the road, the slow-moving traffic exacerbates the air quality issues.

Other Contributing Factors
Shifts in wind patterns, ocean surface cooling, dust particles, and the use of contaminated oil are also being identified as significant factors in the heightened pollution levels. These environmental and human-made elements combined have led to the unprecedented pollution currently being experienced in Mumbai.
