Guwahati: A small industrial town, Byrnihat, situated on the border between Meghalaya and Assam, approximately 2,000 kilometers from Delhi, has been designated as the world’s most polluted city. This alarming revelation comes from the 2024 World air Quality report.
Alarming Air Quality Levels in Byrnihat
The report,compiled by Swiss air quality technology company IQAir,indicates that Byrnihat’s residents are exposed to the most toxic air globally. The primary culprit is the high concentration of PM2.5 particles.
Byrnihat,a hub for various factories including distilleries,and iron and steel plants,recorded an average annual PM2.5 concentration of 128.2 micrograms per cubic meter.This figure starkly contrasts with the world Health Organization’s (WHO) recommended limit of 5 micrograms per cubic meter.
Understanding PM2.5 and Its Dangers
PM2.5 refers to particulate pollutants with a diameter of fewer than 2.5 microns. These tiny particles can penetrate deep into the lungs and bloodstream, leading to severe health issues such as:
- Breathing problems
- Heart disease
- cancer
Sources of PM2.5 include vehicle emissions, industrial discharge, and the burning of wood or crop waste.
Global Ranking of Polluted Cities
According to the iqair report, Byrnihat is followed by other cities with high pollution levels:
- Byrnihat, India
- Delhi, India
- Karaganda, Kazakhstan
- Lahore, Pakistan
- Faridabad, India
Delhi’s air quality has deteriorated, maintaining its status as the most polluted capital city worldwide. The annual average PM2.5 concentration in Delhi rose from 102.4 micrograms per cubic meter in 2023 to 108.3 micrograms per cubic meter in 2024.
India’s Overall Pollution Ranking
India was ranked as the fifth most polluted nation in 2024, a slight improvement from its third position in 2023. However, the report highlights that 13 of the world’s 20 most polluted cities are located in India.
Besides Byrnihat, Delhi, and Faridabad, other Indian cities on the list include mullanpur, Loni, Gurugram, Ganganagar, Greater Noida, Bhiwadi, Muzaffarnagar, Hanumangarh, and Noida.
The report indicates that 35% of Indian cities exceeded the WHO’s annual PM2.5 limit by more than tenfold.
Despite these alarming figures, India experienced a 7% decrease in PM2.5 concentrations in 2024, averaging 50.6 micrograms per cubic meter, compared to 54.4 micrograms per cubic meter in 2023.
Goverment Response and Investigation
meghalaya chief minister Conrad Sangma addressed the issue in the state assembly, stating that the Meghalaya State Pollution Control Board (MSPCB) assessed Byrnihat’s air quality as satisfactory. This contrasts with the “poor to very poor” air quality recorded by a monitoring station in Assam, near the central Academy for State Forest Service.
This indicates that the major sources of air pollution may be attributed to industrial and other activities on the Assam side.
Conrad Sangma, Meghalaya Chief Minister
Mr. Sangma noted that areas in Byrnihat closer to Assam have 20 “red category” industries, which have high pollution potential, while the Meghalaya side has five.
Mr. Sangma has communicated with the Chief Minister of assam, Himanta Biswa sarma, regarding the matter.
I have written a letter to the Assam Chief Minister. I have not received any feedback (yet) but I will speak to him on the phone. It (report) is of great concern to all of us. I am very concerned and I am not very happy. I will definitely take personal interest in this. This is not something that I want our state to be labelled as, especially keeping in mind that tourism is a very significant part of our state.
Conrad Sangma, Meghalaya Chief Minister
He further clarified the situation, emphasizing the need for collaborative action:
I have mentioned in the statement that I laid in the House that being a border area, there are impacts from both sides. I am not saying there is more or less from our industries or from Assam industries but the numbers show that the red category and the industries are almost more on the Assam side than the Meghalaya side. But that does not mean that they are doing more or we are doing less.
Conrad Sangma, Meghalaya Chief Minister
the Meghalaya Chief Minister stressed the importance of cooperation with Assam to address the pollution issue effectively.
So what’s important is that we must come together, we must ensure that we take strict action, a joint program policy to monitor things together and ensure the overall air quality at Byrnihat improves.
Conrad Sangma, Meghalaya chief Minister
On Tuesday, mr. Sangma reported that polluters in Meghalaya had been identified, and closure notices were issued over the past year.
