PM2.5 down by 7% in Faridabad, but it's still 3rd most polluted city

11 Jan 2024
| The Times of India

Faridabad is the only Haryana city listed as a 'non-attainment city' by the National Clean Air Programme (NCAP), as its air quality didn't meet the national ambient air quality standards between 2011 and 2015. According to NCAP data, Faridabad's average PM2.5 concentration was 94.5 µg/m3 in 2019, which dropped to 87.6 µg/m3 in 2020 due to the lockdowns imposed during the pandemic. The number, however, spiked to 95.6 µg/m3 the following year. 'Non-attainment' cities have to reduce PM2.5

Here's what's choking Delhi and NCR. Govt panel reveals major air pollution contributors

02 Nov 2023
| The Economic Times

Noida and Ghaziabad are the main sources of PM2.5 pollution in Delhi. The lack of a unified approach hinders progress in combating air pollution. There is a need for the Uttar Pradesh government to conduct a source apportionment study to identify local sources of pollution in both cities, similar to what has been done in Delhi says Mr Suresh Ramasubramanya Iyer, Senior Fellow and area convener at the Centre for Air Quality Research of The Energy and Resources Institute (TERI).

Exposure to PM2.5 found to increase anaemia, low birth weight risk among Indian children

01 Nov 2023
| The Print

Exposure to fine particle pollution (PM2.5) has been found to increase the risk of anaemia, acute respiratory infection and low birth weight among children in India, according to a study published in the journal Nature Communications. The team from The Energy and Resources Institute (TERI), the Indian Institute of Technology (IIT), Delhi, and other institutes, also suggested that using 'total PM2.5 mass' to measure exposure to air pollution could "substantially underestimate" the true

India's capital has recorded the world's most toxic air as seasonal fires to clear farmland added to pollution from vehicles, construction and coal-fired power plants. The current poor air quality is due to a drop in temperatures and slow wind speeds that's hampered the dispersal of pollution says Dr Anju Goel, Fellow, The Energy and Resources Institute.

Hidden danger in the air? What you need to know about rising ozone pollution

24 Sep 2023
| Wion News

India, unfortunately, is home to numerous highly polluted cities in the world. While particulate matter often dominates headlines, the menace of ozone pollution has been lurking in the shadows. Unlike other pollutants, ozone is not directly emitted from any source, ozone isopleths forms when nitrogen oxides (NOx), volatile organic compounds (VOCs), carbon monoxide (CO) and methane (CH4) react in the presence of sunlight and high temperatures explained Mr R Suresh, Senior Fellow, TERI.

| The Hindu

A "super site" and mobile laboratory (a lab-on-wheels capturing air pollution readings and sources from various parts of the city) are set to be opened by the chief minister, Mr. Arvind Kejriwal. These were used for the "real-time source apportionment study," under which data on Delhi's air were collected. A model (software) was created giving sources of air pollution by using air from the surroundings as input. The source apportionment study is being done by IIT Kanpur, IIT Delhi, TERI, and
