air pollution

The blanket of haze that shrouds most big cities in India has grown denser as air quality continues to dip. Last winter was no different with pollution levels soaring way above permissible limits and posing major risks to public health.      A recent analysis of winter pollution during 2024-25 by the Centre for Science and Environment (CSE) highlights alarming pollution trends in India's megacities, with Delhi leading with the worst air quality. Even megacities outside the Indo-Gangetic Plains (IGP) have seen escalating air quality challenges, despite relatively favourable climatic conditions.  One significant trend across cities like Kolkata, Mumbai, Hyderabad, Chennai,…

“Air pollution is never recorded as a direct cause of death. It’s always a contributing factor,” says Dr Aparna Birajdar, a consultant pulmonologist in Pune. She adds that it is difficult to get data on the impact of air pollution in India because doctors are overworked and have little time to research, while most lung infections are multi-factorial. This is why air pollution and its health consequences are rarely addressed with the urgency they demand.  Moreover, studies of air pollution's effects largely focus on adults, with data on children scarce. In 2019, air pollution caused about 6.7 million deaths globally,…

“My child’s commute to school is a half-hour ride, but it takes an hour for her to reach home everyday. The commute itself makes her so tired and the dust is so high during the after-school hour that her cough almost always worsens when she comes back home,” says Tanu, worried mother of a second-grade child in Bengaluru. Tanu is just one parent among the vast numbers across our cities, as air pollution puts their children's health and well-being at grave risk. In 2021, 15% of all global deaths in children under five were linked to air pollution. As per…

In an earlier article, we highlighted how Bengaluru lags behind in utilisation of funds received under the National Clean Air Programme, and how that, coupled with the lack of an elected municipal body, threatens the prospect of climate action. In November 2023, BBMP launched the Bengaluru Climate Action and Resilience Plan (BCAP), with the objective of addressing climate issues in the city.  Following the launch of the BCAP, a climate action cell was established in February 2024 to coordinate the work of different departments towards climate action. Some of these plans are to be realised utilising NCAP funds, either exclusively…

Bengaluru’s air quality has been seriously worsening post COVID. The annual levels of PM10 saw a decline between 2018 and 2021, but has been slowly increasing since then. Government authorities say that the air quality in Bengaluru is better compared to other cities. But while the PM2.5 levels may conform to the national standards, according to a Greenpeace report it is still four to nine times higher than WHO standards. There is thus a huge need for improvement. The city, however, has used very little of the clean air funds received under the National Clean Air Programme (NCAP). Also non-utilisation…

The Central Pollution Control Board and the State Pollution Control Boards are the primary custodians for preventing and controlling all forms of pollution in our country. Despite their significant role in environmental protection, the public is mostly unaware of the functions of these regulatory bodies, due to insufficient research. Therefore, we at Citizen consumer & civic Action Group (CAG) have attempted to understand the functions of the Tamil Nadu Pollution Control Board (TNPCB), through a study titled ‘The Tamil Nadu Pollution Control Board in Retrospect: An Examination of Selected Parameters from 2017 to 2022.’ Read more: Fisherfolk lament as environmental…

October 2023 was a shocker for Mumbai. The coastal city has historically recorded lower AQI levels as compared to Delhi, which is notorious for its poor air quality. But the tables turned in October 2023, with AQI in Mumbai reaching dangerously high levels of up to 300, surpassing Delhi for several days. This led to a slew of respiratory ailments, more so among the vulnerable populations. PM2.5 levels have, in fact, seen a consistent increase in Mumbai over the past three years. Dr Jui Mandke, a paediatric surgeon practising in Mumbai, says, “In October 2023, we encountered the maximum number…

This is the first of a two part story looking at how women workers in the construction industry are disproportionately affected by air pollution and other work place related issues. Women workers in the construction sector, the second largest employer of women after agriculture, are disproportionately affected by issues like air pollution. Not only at their work place but also at their homes. Many women construction workers suffer from illnesses like breathlessness but delay treatment due to the lack of options before them. “There have been no studies carried out about the health impact of construction activities on the workers,”…

First electric bus unveiled Bengaluru’s first electric bus, nine-metre-long and non-AC, was unveiled by Transport Minister B Sriramulu. The bus can run 120 km on a single charge, and carry 33 passengers. The BMTC (Bangalore Metropolitan Transport Corporation) had got the e-bus built by the Uttar Pradesh-based JBM Auto Limited.  This is the first of 90 electric buses to be inducted by BMTC by December. Each bus will cost Rs 90 lakh, of which about Rs 60 lakh is contributed by grants from the Smart Cities Mission. Over the next three years, the fleet might expand to 500. The first…

72% COVID patients have new variants About 71.7% of 1,018 patients in the BBMP (Bruhat Bengaluru Mahanagara Palike) and Bengaluru Urban district limits had the latest variants of SARS-CoV-2. Out of the 2,774 samples received for genomic sequencing, 1,738 were processed. This includes 525 patients with the Delta variant, 116 with Kappa, 88 with Alpha, and one with Delta Plus. In all, 730 patients have the new variants. A member of the state genomic surveillance committee said that the BBMP should be acting on the data. Quick tracing is crucial. It is important to check if patients with the Delta…
