Owing to a rise in humidity and light winds, the overall air quality of the national capital slipped to the ‘severe’ zone on Saturday, despite the authorities predicting it would remain in the ‘very poor’ category.

“Calm winds along with a spike in humidity levels because of an induced Cyclonic Circulation over Northern Plains are the major contributors for a hike in pollution levels in Delhi and adjoining areas,” Mahesh Palawat, Director at private weather forecasting agency Skymet told IANS.

He said that the pollution levels might increase in the coming days as humidity levels are expected to go up due to rains in Punjab, Haryana and Rajasthan.

“Around January 13 and 14, moderate to dense fog is expected to make a comeback, which will result in high pollution levels and minimums will see a drop by a couple of degrees,” he said.

However, the Skymet Director said that post January 15, the air quality might start improving due to cold, north-westerly winds which will blow over the plains of the country.

The System of Air Quality and Weather Forecasting And Research (SAFAR), in its daily pollution analysis, has been maintaining that the air quality in Delhi won’t go beyond the ‘very poor’ category.

On Saturday however, many areas in Delhi and adjoining areas at 12 p.m recorded ‘severe’ levels of toxic particulate matter (PM) 2.5.

Anand Vihar at 448, Dwarka sector-8 at 450, ITO at 413, Mundka at 438, Delhi University North Campus at 416, R.K. Puram at 415, and Wazirpur at 434 – all recorded ‘severe’ levels of PM2.5.

Other areas like Jawaharlal Nehru Stadium, Ashok Vihar, Burari Crossing, Vivek Vihar, Sirifort, Okhla Phase-2 also fared in the same category.

On Wednesday and Thursday, Delhi-NCR witnessed its first better days of the year with the air quality recorded in the ‘poor’ zone.

Air Pollution, Stress Associated with Thought Problems in Kids: Researchers

Stress likely leads to wide-ranging changes in, for example, epigenetic expression, cortisol, inflammation, and brain structure and function

Parents, please take note. Researchers have revealed that kids with elevated exposure to early life stress in the home and increased prenatal exposure to air pollution exhibited heightened symptoms of attention and thought problems.

Early life stress is common in youth from disadvantaged backgrounds who also often live in areas with greater exposure to air pollution, according to the study, published in the Journal of Child Psychology and Psychiatry.

“Prenatal exposure to polycyclic aromatic hydrocarbons, a neurotoxicant common in air pollution, seems to magnify or sustain the effects of early life social and economic stress on mental health in children,” said study first author David Pagliaccio from Columbia University in the US.

“Air pollutants are common in our environment, particularly in cities, and given socioeconomic inequities and environmental injustice, children growing up in disadvantaged circumstances are more likely to experience both life stress and exposure to neurotoxic chemicals,” said senior author Amy Margolis.

Air pollution has negative effects on physical health, and recent work has begun to also show the effects on mental health. Life stress, particularly in early life, is one of the best-known contributors to mental health problems.

This new study examined the combined effects of air pollution and early life stress on school-age children.

According to the researchers data were collected from the CCCEH Mothers and Newborns longitudinal birth cohort study in Northern Manhattan and the Bronx, which includes many participants who self-identify as African American or Dominican.

Mothers wore an air monitoring backpack during the third trimester of pregnancy to measure exposure to air pollutants in their daily lives.

When their children were 5 years old, mothers reported on stress in their lives, including neighbourhood quality, material hardship, intimate partner violence, perceived stress, lack of social support, and general distress levels.

Mothers then reported on their child’s psychiatric symptoms at ages 5, 7, 9 and 11.

The combined effect of air pollution and early life stress was seen across several measures of thought and attention problems/ADHD at the age 11.

The effects were also linked to PAH-DNA adducts–a dose-sensitive marker of air pollution exposure.

The researchers said that PAH and early life stress may serve as a “double hit” on shared biological pathways connected to attention and thought problems.

Stress likely leads to wide-ranging changes in, for example, epigenetic expression, cortisol, inflammation, and brain structure and function.

The mechanism underlying the effects of PAH is still being interrogated; however, alterations in brain structure and function represent possible shared mechanistic pathways, the study said. (IANS)
