Air quality data shows instant values, not comparable to PCB data clarifies Climate Trends

Equipment used is calibrated and the data has 90% match to the data from approved equipment, says the company that released the report.

In response to the statement issued by the Karnataka State Pollution Control Board refuting the findings of the air-quality monitoring work released by Co Media Lab and Climate Trends, the organisations have in turn issued a clarification that the exercise was done to measure peak hour pollution levels in the city for a select amount of time on select routes in the morning as well as in the evening. The objective of the study was to measure and bring to fore the personalised exposure levels one is being subjected to while traveling on busy roads for a few hours every day.

The press note issued on the 19th revealing the data has explicitly mentioned that the results are not comparable to the 24hr averages or the annual regulatory limits as it highlighted Particulate Pollution values for a short period of time only. Moreover, the values released to the press were the instant values for which regulatory limits do not apply and the issued press note emphasised the same.

The Pollution Control Board particularly mentions that the exercise carried out by us is in violation of the monitoring protocols and guidelines issued by the Ministry of Environment, Forests and Climate Change, these are guidelines laid out for measuring ambient air quality and the exercise was aimed at localised, personal exposure levels only. The two are not to be compared. Further, the was study also done to inform the public and citizen leaders who are actively championing the cause of clean air to engage in collective action with administrative bodies to minimise the impacts of pollution before the situation worsens.

This is a press note sent by Aishwarya Sudhir of Climate Trends, on behalf of Climate Trends and Co Media Lab, published here with minimal edits, in the section Message Forward, as a nonprofit public interest message.

Study shows TNPCB ill-equipped to monitor the environmental impact of pollution

The scientific team of TNPCB is working at half its strength, affecting the Board's ability to carry out inspections in Chennai and other parts of the State.

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 โ€˜The Tamil Nadu Pollution Control Board in Retrospect: An Examination of Selected Parameters from 2017 to 2022.โ€™ Read more: Fisherfolk lament as environmental…

Why the national programme for clean air failed a gasping Mumbai

Mumbai has seen an alarming decline in air quality. A look at the limited impact of the National Clean Air Programme on mitigating pollution.

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, โ€œIn October 2023, we encountered the maximum number…
