Air Pollution Linked to 3.2 Million New Diabetes Cases in One Year

Nearly 10 million years of healthy life were lost in 2016 due to pollution-linked diabetes, representing about 14 per cent of all years of healthy life lost due to diabetes from any cause

Outdoor air pollution even at levels deemed safe may be associated with an increased risk of diabetes globally, with India being at a greater risk due to lack of air cleaning policies, scientists said in a report in Lancet.

The findings showed that air pollution contributes to development of diabetes by reducing insulin production and triggering inflammation, which prevents the body from converting blood glucose into energy that the body needs.

The overall risk of pollution-related diabetes is tilted more toward lower-income countries such as India that lack the resources for environmental mitigation systems and clean-air policies, Lancet Planetary Health report said.

“Our research shows a significant link between air pollution and diabetes globally,” said Ziyad Al-Aly, from the University of Washington in St. Louis, US.

“We found an increased risk, even at low levels of air pollution currently considered safe by the US Environmental Protection Agency (EPA) and the World Health Organization (WHO).

“This is important because many industry lobbying groups argue that current levels are too stringent and should be relaxed. Evidence shows that current levels are still not sufficiently safe and need to be tightened,” Aly explained.

The researchers estimated that pollution contributed to a little more than three million new diabetes cases globally in 2016, which represented about 14 per cent of all new diabetes cases globally that year.

Nearly 10 million years of healthy life were lost in 2016 due to pollution-linked diabetes, representing about 14 per cent of all years of healthy life lost due to diabetes from any cause.

According to the UN 2018 Sustainable Development Goals Report, an estimated 4.2 million people died as a result of high levels of ambient air pollution.

In the study, the team analysed data from more than one million participants without a history of diabetes, who were followed for a median of eight and a half years.

They also looked at particulate matters, airborne microscopic pieces of dust, dirt, smoke, soot and liquid droplets.

Poverty-stricken countries facing a higher diabetes-pollution risk include Afghanistan, Papua New Guinea and Guyana, while richer countries such as France, Finland and Iceland experience a lower risk, the study said. (IANS)

Air Pollutants Can Be Stopped If They Are Frozen : Scientists

The air-quality across the NCR was very poor

Freezing pollutants can prevent deadly outdoor air pollution — thought to cause more than three million premature deaths worldwide every year — from seeping indoors by 99 per cent, scientists have discovered.

The research, by a team of scientists from the Nottingham Trent University in the UK and the Chinese Academy of Sciences, involved studying the effectiveness of cryogenics for indoor air purification, by removing the gaseous pollutants and tiny particulates caused by haze.

The team found that as they circulated haze-polluted air through a cryogenic condenser, the finer particles stuck together in the condenser tube before dropping out by gravity, and emerging as clean air.

Their method was able to remove 99 per cent of particulates and 98 per cent of nitrogen oxide pollutants.

“Hazardous outdoor air pollution has severely affected indoor air quality, threatening the health of billions of people,” said Professor Robert Mortimer, Dean of the School of Animal, Rural and Environmental Sciences at Nottingham.

“Outdoor air pollution in cities is a global problem. While there are some existing technologies to purify indoor air, they can be inefficient, expensive or produce harmful by-products.

“When outdoor air quality is poor, people tend to spend even more time indoors – but outdoor pollution also leads to indoor pollution and people are still impacted.”

The experiments, reported in the journal Science of the Total Environment, showed that by simply circulating polluted air through a small freezing chamber we can remove most of the fine particles and gas pollutants.

“Our study makes it possible to add an ‘air cleaner’ option to household appliances in areas which might experience extremely poor air conditions. By controlling indoor air pollution and improving air quality in this way, this work could be greatly beneficial for public health,” added Gang Pan, Professor at the varsity.

It is hoped that the work could pave the way for simple modification of air conditioning and humidifier units so that they can also clean polluted indoor air, the team said.

Delhi and the National Capital Region (NCR) on Sunday witnessed “very poor” air quality with the minimum temperature recorded at 12.4 degrees Celsius, two notches below the season’s average.

The air-quality across the NCR was very poor, according to System of Air Quality and Weather Forecasting And Research.

The humidity at 8.30 a.m. was 87 per cent. The maximum temperature was likely to hover around 28 degrees Celsius. (IANS)
