Azamgarh UP's most polluted district: IIT-K report
Spearheaded by the Indian Institute of Technology, Kanpur (IIT-K) Centre of Excellence – Advanced Technologies for Monitoring Air-quality iNdicators (CoE-ATMAN), the AMRIT programme addresses significant gaps in air quality data and analysis in rural areas, which account for a large proportion of India's population.
A report by the IIT-K on Transforming Air Quality Monitoring in UP shows Bhadohi and Shamli having the highest recorded pollution levels after Azamgarh.
The PM 2.5 recorded in these two districts in 2024 stood at 168.7 and 122.9, respectively. The report pointed out that, unlike urban centres, rural areas often lack systematic air quality monitoring, despite facing pollution from sources like agricultural burning, traditional cooking methods, and industrial emissions. Under the AMRIT project, 826 sensors have been placed across the state, ensuring robust coverage of both rural and urban areas.
By leveraging indigenous low-cost technologies, the AMRIT project provides real-time, actionable data that empowers policymakers and local authorities to implement targeted solutions. Leading the project, Prof Sachchi Nand Tripathi said the air quality data reveal substantial seasonal fluctuations in PM 2.5 levels, with the highest pollution levels recorded during winter months, particularly in Nov and Dec.
The findings show that winter conditions exacerbate the impact of emissions due to temperature inversions and stagnant air conditions.
The year-on-year analysis shows notable air quality improvements in the state during the ongoing winter season in 2024. The average PM 2.5 levels decreased from 101μg/m³ in Oct 2023 to 76 μg/m³ in Oct 2024, reflecting a 25% decrease. The trend in improvement continued in Nov and Dec 2024, as a 26% and 30% decrease in PM 2.5 levels were observed compared to the respective months in 2023, shows the report.
"The AMRIT project's robust sensor network makes such granular analysis possible, enabling evidence-based decision-making for sustainable air quality management," said Prof Tripathi.

India's health survey data reveals 13% children born prematurely, 17% with low birth weight
New Delhi: India's demographic health survey 2019-21 reveals that 13 per cent of children were born prematurely, and 17 per cent with a low weight at birth, with air pollution contributing to the adverse birth outcomes . Researchers from the Indian Institute of Technology, Delhi, International Institute for Population Sciences, Mumbai, and institutes in the UK and Ireland looked at the National Family Health Survey-5 and remote sensing data to analyse how exposure to air pollution in pregnancy impacted the delivery outcomes. The team found that an increased exposure to PM2.5 during pregnancy was related with a 40 per cent chance of low birth weight, and 70 per cent of premature delivery. Climate conditions, such as rainfall and temperature, were found to have a greater link with adverse birth outcomes. The study, published in the journal PLoS Global Public Health, also found that children living in the northern districts of India could be more vulnerable to the ambient air pollution. Measuring under 2.5 microns in diameter, fine particulate matter 2.5 (PM2.5) is considered among the most harmful air pollutants, sources of which include burning of fossil fuels and biomass. The researchers found higher levels of PM2.5 pollutants over the upper Gangetic region, covering states like Uttar Pradesh, Bihar, Delhi, Punjab and Haryana, and lower levels in the country's southern and north-eastern regions. A higher prevalence of premature births was seen in northern states, such as Himachal Pradesh (39 per cent), Uttarakhand (27 per cent), Rajasthan (18 per cent), and Delhi (17 per cent). Mizoram, Manipur and Tripura exhibited a lower prevalence of the trend. Punjab was found to have the highest prevalence of lower birth weight at 22 per cent, followed by Delhi, Dadra and Nagar Haveli, Madhya Pradesh, Haryana, and Uttar Pradesh. North-east India fared far better on the metric, the authors said. "Utilising data from the national family health survey and raster images, the study employs various statistical analyses and spatial models to elucidate the connection between in-utero exposure to air pollution and birth outcomes," the authors wrote. They "observed that approximately 13 per cent of children were born prematurely, and 17 per cent were born with low birth weight." Further, an increase of 10 microgram per cubic metre in PM2.5 exposure was associated with an increase of five per cent in the prevalence of low birth weight, and 12 per cent in premature birth. The team added that 18 per cent of children born in the five years preceding the National Family Health Survey-5 had a low weight at birth. The authors called for targeted interventions, especially in the northern districts, and an intensification of the National Clean Air Program. Launched in 2019, the programme is aimed at improving air quality in India by addressing PM levels. The researchers also advocated for climate adaptation strategies, such as heat action plans and water management, to be included in public health planning. Awareness of risks due to air pollution and climate change should be raised as part of public health initiatives, especially among pregnant women, the team said.
