Indian and American experts will chalk out strategies to combat air pollution caused by crop burning, vehicular emission and construction dust at a workshop that began, here on Thursday.

The three-day workshop, organised by the North India Office of the US Embassy in collaboration with not-for-profit RTI International, is aimed at sharing the US best practices in combating air pollution to reduce emissions of fine-particulate matter and other pollutants in North India.

“Based on the 2016 Global Burden of Disease estimates, about 1.6 million deaths per year in India have been attributed to air pollution,” the release quoted him as saying. Pixabay

It will focus on strategies to minimise emissions, behavioural changes for accepting new alternatives, adoption of tools for estimation of emissions and air quality impacts, enhancing involvement of the private sector and the public as part of the change and developing an integrated regulatory approach.

Prakash Doraiswamy, Principal Air Quality Scientist at RTI International, said several north Indian cities rank among the top 25 cities in the world with fine particle (PM 2.5) concentrations 10-17 times higher than World Health Organisation’s guidelines, as per the World Global Ambient Air Quality Database (2018).

Air Pollution Raises Anxiety, Depression Risks in Kids, Says Study

Among those exposed to higher levels of traffic-related air pollution, there were significant increases of myo-inositol in brain compared with those with lower pollution exposure

A recent report had said that 22 of the world's 30 worst cities for air pollution are in India, with Delhi again ranking as the world's most polluted capital. VOA

A new evidence suggests air pollution is not just associated with asthma and respiratory diseases, but may also impact metabolic and neurological development of children, putting them at an increased risk of anxiety and depression, says a study.

“Recent evidence suggests the central nervous system is particularly vulnerable to air pollution, suggesting a role in etiology of mental disorders, like anxiety or depression,” said study lead author Kelly Brunst, Assistant Professor at the University of Cincinnati in the US.

“This is the first study to use neuro-imaging to evaluate exposure to traffic-related air pollution, metabolite dysregulation in brain and generalised anxiety symptoms among otherwise healthy children,” Brunst said.

For the study, published in the journal Environmental Research, the researchers evaluated imaging of 145 children at an average age of 12 years, looking specifically at levels of myo-inositol in brain through a specialised MRI technique, magnetic resonance spectroscopy.

Myo-inositol is a naturally-occurring metabolite, mainly found in specialised brain cells known as glial cells, which assists in maintaining cell volume and fluid balance in brain and serves as a regulator for hormones and insulin in the body. Rise in myo-inositol levels correlate with increased population of glial cells, which often occurs in states of inflammation.

Among those exposed to higher levels of traffic-related air pollution, there were significant increases of myo-inositol in brain compared with those with lower pollution exposure, researchers said.

They also observed rise in myo-inositol to be associated with more generalised anxiety symptoms. “In the higher, recent exposure group, we saw a 12 per cent increase in anxiety symptoms,” said Brunst.

Brunst, however, noted that the observed increase in reported generalised anxiety symptoms in this cohort of typically developing children was relatively small and were not likely to result in a clinical diagnosis of an anxiety disorder. (IANS)
