Emission from diesel engines linked to premature death

US, Feb 27: Some 385,000 people worldwide died prematurely in 2015 from air pollution caused by vehicle exhaust emissions, a US study found Wednesday, which singled out diesel engines as the main culprit.

Diesel vehicles were responsible for 47 percent of the deaths, it said, but the figure jumped as high as 66 percent in France, Germany, Italy and India where diesels make up a large proportion of cars on the road.

The study was carried out by researchers from the International Council on Clean Transportation (ICCT), the non-governmental group that blew the whistle on Volkswagen's "dieselgate" emissions cheating scandal in 2015 and two US universities.

"The high public health burden of diesel vehicles in Europe underscores the need for world-class emissions standards to be accompanied by robust compliance and enforcement," said ICCT co-author Joshua Miller, calling for urgent action to replace high-emissions vehicles.

Researchers studied the impact of fuel emissions from diesel and non-diesel vehicles, as well as agricultural and construction machinery and their impact on our health. They found that the global transportation sector was responsible for 11 percent of the 3.4 million premature deaths annually attributed to pollution from fine particles (PM2.5) and ground-level ozone exposure.

The cost of the health burden caused by transport pollution, which has been linked to lung and heart diseases, strokes and diabetes, added up to $1 trillion (880 billion euros) in 2015, they said.

In China alone, some 114,000 people were killed by vehicle exhausts that year, but that still only accounted for just over 10 percent of all deaths linked to air pollution there.

The United States saw 22,000 deaths from transport pollution, of which 43 percent were linked to diesels. India meanwhile recorded 74,000 premature deaths from vehicle exhausts, compared with 13,000 in Germany, 7,800 in Italy and 6,400 in France.

Relatively speaking however, the picture was worst in Germany with 17 premature deaths blamed on transport pollution per 100,000 residents, three times higher than the global average.

Milan, Turin, Stuttgart, Kiev, Cologne, Berlin and London were among the deadliest cities in terms of transport pollution, the researchers noted. The authors cautioned that their estimates were "conservative" as their study did not take into account all types of harmful emissions or pollution-linked diseases. "Consideration of these impacts would likely increase the estimate of health impacts from vehicle exhaust emissions," they warned.

Panaji, May 11: Amid the COVID-19 outbreak, most of the people are more concerned about the health of their near and dear ones than their own well-being, says a study conducted by a leading business school in Goa.

People are now more conscious about any bodily changes, and even mild cold, cough and sneezing, it says.

The study, on public's reaction towards COVID-19 outbreak by gauging their psychological response in terms of anxiety and their coping behaviour, was conducted by the Goa Institute of Management's Dr Divya Singhal and Prof Padhmanabhan Vijayaraghavan.

It took into account inputs from 231 respondents residing in various parts of the country.

"Nearly 82.25 per cent of the respondents were more worried about the health of their loved ones than their own well-being," Singhal said.

"Majority of the respondents have become conscious of any bodily changes, sensations, a mild cold, cough, sneezing and experience concern, and attribute those changes to the symptoms of COVID-19," she said.

Besides, more than 50 per cent of the respondents said their social media usage has gone up as well as their time spent on watching movies and shows through online medium, the official said.

The respondents agreed that their technology usage to connect with friends and relatives has gone up, she said.

The study also indicated that a large group of respondents found it "depressing" to read forwarded messages on the deadly disease.

"An overwhelming majority of the respondentsagreed that they discourage unverified forwarded messages about COVID-19 on social media," says the study.

It also found that 41 per centof the respondents were not doing any physical activity, like yoga, during the lockown period, while another 19 per cent were not sure about engaging themselves in physical activities.

Besides, 57 per cent of the respondents were not engaged in any mind-calming practices like meditation, and 18 per cent were not sure about taking up meditative practices, the study said.

The respondents included 145 men and 86 women, aged 18 and above, with nearly 60 per cent of them residing in non- metro cities and rest from metros.

About 47.62 per cent of the respondents were employed in private or government sectors, and the remaining included students, retired persons and homemakers.

Washington D.C., Jan 5: After a woman filed a lawsuit against a diet soda company, the California court has declared that the beverage does not promise to help buyers in losing weight.

The woman had gulped down the drink for over a decade but did not lose inches as a result.

The three-judge panel declared during the hearing: "The prevalent understanding of the term in (the marketplace) is that the 'diet' version of a soft drink has fewer calories than its 'regular' counterpart."

However, the members of the US 9th circuit court have felt that the consumers tend to make out something of their own that is unreasonable and eventually hamper the reputation of brands through a deceptive allegation, reports Fox News.

The response was due to a misleading case filed against Diet Dr Pepper by Shana Becerra from Santa Rosa, California. Shana claimed that she has been addictively purchasing the low-calorie beverage for the past 13 years hoping for losing some fat but failed to lose even a single inch.

The woman also stated that the attractive and fit models misled her into believing that drink will help her in perfecting her body like them.

However, the court's decision was that advertisements are for representational purposes only. "Cannot be reasonably understood to convey any specific meaning at all," as written by Judge Jay Bybee.

Shana had last week made such allegation against Diet coke as well where the court came to a similar verdict. She claimed that she had found various studies where it is evident that the artificial sweetener aspartame used in diet beverages actually boosts weight gain.

But the artificial sweetener is approved in by the concerned administrative department and thus is used in most American drinks.

There is no evidence that the Bacille Calmette-Guerin (BCG) vaccine, which is primarily used against tuberculosis, protects people against infection with the novel coronavirus, the World Health Organization (WHO) said.

The WHO therefore didn't recommend BCG vaccination for the prevention of COVID-19 in the absence of evidence, according to its daily situation report on Monday, Xinhua news agency reported.

"There is experimental evidence from both animal and human studies that the BCG vaccine has non-specific effects on the immune system. These effects have not been well characterized and their clinical relevance remains unknown," WHO stated.

Two clinical trials addressing the question are underway, and WHO will evaluate the evidence when it is available, it noted.

BCG vaccination prevents severe forms of tuberculosis in children and diversion of local supplies may result in an increase of disease and deaths from the tuberculosis, it warned.
