The Kerala government has decided to install air quality monitoring devices in select hospitals of the coastal city, which is reeling under toxic haze from the fire at the Brahmapuram waste treatment plant. State Health Minister Veena George said installing the air quality monitoring devices will help identify the possibility of people getting sick due to the worsening air quality. "The devices will help identify the possibility of people falling sick and ensure preventive measures to be taken well in advance," George said in a release. Meanwhile, the Ernakulam district administration and the State Disaster Management Authority has held an online discussion on the fire situation with the New York Fire Safety Department Deputy Chief, George Healy. During the meet, Haley urged the administration to remain cautious as there are chances that fire may breakout again even after it appears to have been doused, the district administration said in a statement. The New York Fire safety offi

Chinese EV maker JAC has showcased the world's first electric vehicle (EV) that is powered by a cheaper sodium-ion battery which could help reduce the cost of future EVs by 10 per cent

Researchers from Indian Institute of Technology (IIT) Kharagpur have found increasing atmospheric pollution in rural India using Nitrogen Dioxide (NO2) measurements from satellites. The researchers found that air pollution is not typically an urban phenomenon but can affect the environment in rural pockets also. They conducted an analysis of the rural air quality to assess the extent of air pollution by measurements of NO2 through satellite imaging. The analysis exposes increasing trends (0.050.441015molec./cm2/yr) of NO2 in the rural regions of India, the institute said in a statement on Wednesday. The statement said a team of Prof Jayanarayanan Kuttippurath and Research Scholar Mansi Pathak of Centre for Ocean, River, Atmosphere and Land Sciences (CORAL) of IIT Kharagpur analysed the significant impact of urban pollution on the air quality of rural India by differentiating the pollution in two zones - rural and urban - and assessing the extent of air pollution in rural India.

According to New UC Riverside research, nitrogen released by gas-powered machines causes dry soil to let go of carbon and release it back into the atmosphere, where it can contribute to climate change

Respiratory illnesses increase during the winter season due to air pollutants settling down in the atmosphere

Easing of proximity norms will not only impact air and water quality but could also turn vast tracts of farm land barred, say experts

An simple, easy-to-construct air filter can protect against illness caused not only by viruses but also by chemical pollutants, according to a study. The filter named Corsi-Rosenthal boxes, or cubes, can be constructed from materials found at hardware stores: four MERV-13 filters, duct tape, a 20-inch box fan and a cardboard box. "The findings show that an inexpensive, easy-to-construct air filter can protect against illness caused not only by viruses but also by chemical pollutants," said study lead author Joseph Braun, an associate professor at Brown University in the US. "This type of highly-accessible public health intervention can empower community groups to take steps to improve their air quality and therefore, their health," Braun said in a statement. As part of a project, boxes were assembled by students and campus community members and installed in the School of Public Health as well as other buildings on the Brown University campus. To assess the cubes' efficacy at remov

Bad air quality days continue to haunt the Indo-Gangetic Plains with the air quality Index (AQI) oscillating between 'poor' and 'severe' categories

Delhi Chief Minister Arvind Kejriwal on Friday said identification of sources of air pollution on a real-time basis has now started in the national capital. He was reviewing the progress of the 'Real-time Source Apportionment Project'. The project approved by the Cabinet in October 2021 and set up in November 2022 has been undertaken by the Delhi Pollution Control Committee (DPCC) in collaboration with the Indian Institute of Kanpur (IIT-K), Indian Institute of Delhi (IIT-D) and The Energy and Resources Institute (TERI). The IIT team is trying to recognise more detailed identification of the types of sources, exact timing and location of pollution emission, he said. According to a statement issued by the Delhi government, the real-time source apportionment study consists of a supersite with state-of-the-art air analysers and a mobile air quality monitoring system that will measure the level of various substances in the air above Delhi. "Identification of sources of air pollution o

Terming air pollution as a public health crisis for South Asia, the report highlights that this crisis not only imposes high economic costs but also cause nearly 2 million premature deaths each year

India needs to train at least 10 lakh people in the next five years for air quality management, according to a new report, which also says around 50,000 jobs could be created in the sector. The report has been prepared by the International Forum for Environment, Sustainability & Technology (iForest) with the support of the World Bank Group. It highlights the need of a national-level programme to develop the capacity of all stakeholders cities, state and central government agencies, private sector, NGOs and media -- to effectively tackle the problem of air pollution. "Our report shows that we need to train at least 1 million (10 lakh) people over the next five years for air quality management. This will also create tens of thousands of new jobs in the public and private sector to plan, monitor, mitigate, and control air pollutants," said Chandra Bhushan, the CEO of iFOREST and the lead author of the report. He said the report is the first attempt of its kind to map the ...

Delhi and Kolkata reported 106 and 99 deaths per 1 lakh population in 2019 which could be attributed to PM2.5 pollution, according to a new report published by US-based Health Effects Institute on Wednesday. In 2019, Delhi recorded an annual average PM2.5 concentration of 110 microgram per cubic metre, the highest among the most-populous cities in the world, followed by Kolkata (84 microgram per cubic metre), said the report "Air Quality and Health in Cities" by the State of Global Air Initiative, a collaboration between the Health Effects Institute and the Institute for Health Metrics and Evaluation's Global Burden of Disease project. The report summarizes data on air pollution exposures and associated health impacts in 7,239 cities (with minimum population of 50,000) from 2010 to 2019. It combines ground-based air quality data with satellites and models to produce air quality estimates for cities around the world. PM2.5 refers to fine particles (measuring 2.5 m or less in diameter
