Beer, wine bottles contain toxic substances: Study

London, Jun 29: Bottles of beer, wine and spirits contain potentially harmful levels of toxic elements, such as lead and cadmium, in their enamelled decorations, a study has found.

Researchers at the University of Plymouth in the UK analysed both the glass and enamelled decorations on a variety of clear and coloured bottles readily available in shops and supermarkets.

They showed that cadmium, lead and chromium were all present in the glass, but at concentrations where their environmental and health risks were deemed to be of low significance.

However, the enamels were of greater concern, with cadmium concentrations of up to 20,000 parts per million in the decorated regions on a range of spirits, beer and wine bottles, and lead concentrations up to 80,000ppm in the decor of various wine bottles. The limit for lead in consumer paints is 90ppm.

The study, published in the journal Environmental Science and Technology, also showed the elements had the potential to leach from enamelled glass fragments, and when subjected to a standard test that simulates rainfall in a landfill site, several fragments exceeded the US Model Toxins in Packaging Legislation and could be defined as "hazardous".

He has previously shown that the paint or enamel on a wide variety of items, including playground equipment, second-hand toys and drinking glasses, can feature levels of toxic substances that are potentially harmful to human health.

"It has always been a surprise to see such high levels of toxic elements in the products we use on a daily basis. This is just another example of that, and further evidence of harmful elements being unnecessarily used where there are alternatives available. The added potential for these substances to leach into other items during the waste and recycling process is an obvious and additional cause for concern," said Dr Andrew Turner from the University of Plymouth.

For the study, bottles of beer, wine and spirits were purchased from local and national retail outlets between September 2017 and August 2018, with the sizes ranging from 50 ml to 750 ml.

They were either clear, frosted, green, ultraviolet-absorbing green (UVAG) or brown with several being enamelled over part of the exterior surface with images, patterns, logos, text and/or barcodes of a single colour or multiple colours.

Out of the glass from 89 bottles and fragments analysed using x-ray fluorescence (XRF) spectrometry, 76 were positive for low levels of lead and 55 positives for cadmium, according to the study.

Chromium was detected in all green and UVAG bottles, but was only in 40% of brown glass and was never in clear glass, it stated.

Meanwhile, the enamels of 12 products out of 24 enamelled products tested were based wholly or partly on compounds of either or both lead and cadmium.

"Governments across the world have clear legislation in place to restrict the use of harmful substances on everyday consumer products," Turner said.

"But when we contacted suppliers, many of them said the bottles they use are imported or manufactured in a different country than that producing the beverage. This poses obvious challenges for the glass industry and for glass recycling and is perhaps something that needs to be factored into future legislation covering this area," he added.

Washington D.C., May 9: Do the middle age feel much stressful now, and seems to have changed over time, if compared to the life in the 90s? Well, this recent study indicates that it might be true.

The study has signalled to the fact that life may become more stressful majorly for middle-aged people than it was in the 1990s. The researchers reached this analysis even before the novel coronavirus started sweeping the globe.

A team of researchers led by Penn State found that across all ages, there was a slight increase in daily stress in the 2010s compared to the 1990s. But when researchers restricted the sample to people between the ages of 45 and 64, there was a sharp increase in daily stress.

"On average, people reported about 2 percent more stressors in the 2010s compared to people in the past," said David M. Almeida, professor of human development and family studies at Penn State.

"That's around an additional week of stress a year. But what really surprised us is that people at mid-life reported a lot more stressors, about 19 percent more stress in 2010 than in 1990. And that translates to 64 more days of stress a year."

Almeida said the findings were part of a larger project aiming to discover whether health during the middle of Americans' lives has been changing over time.

"Certainly, when you talk to people, they seem to think that daily life is more hectic and less certain these days," Almeida said.

For the study, the researchers collected data from 1,499 adults in 1995 and 782 different adults in 2012.

Almeida said the goal was to study two cohorts of people who were the same age at the time the data was collected but born in different decades. All study participants were interviewed daily for eight consecutive days.

During each daily interview, the researchers asked the participants about their stressful experiences throughout the previous 24 hours.

They asked questions related to arguments with family or friends or feeling overwhelmed at home or work, so and so. The participants were also asked how severe their stress was and whether those stressors were likely to impact other areas of their lives.

"We were able to estimate not only how frequently people experienced stress, but also what those stressors mean to them," Almeida said.

"For example, did this stress affect their finances or their plans for the future. And by having these two cohorts of people, we were able to compare daily stress processes in 1990 with daily stress processes in 2010," Almeida added.

After analyzing the data, the researchers found that participants reported significantly more daily stress and lower well-being in the 2010s compared to the 1990s.

Additionally, participants reported a 27 percent increase in the belief that stress would affect their finances and a 17 percent increase in the belief that stress would affect their future plans.

Almeida said he was surprised not that people were more stressed now than in the 90s, but at the age group that was mainly affected.

"We thought that with economic uncertainty, life might be more stressful for younger adults. But we didn't see that. We saw more stress for people at mid-life," Almeida said.

"And maybe that's because they have children who are facing an uncertain job market while also responsible for their own parents. So it's this generational squeeze that's making stress more prevalent for people at mid-life," he concluded.

The World Health Organization (WHO) is reviewing a report that suggested its advice on the novel coronavirus needs updating after some scientists told the New York Times there was evidence the virus could be spread by tiny particles in the air.

The WHO says the Covid-19 disease spreads primarily through small droplets, which are expelled from the nose and mouth when an infected person breaths them out in coughs, sneezes, speech or laughter and quickly sink to the ground.

In an open letter to the Geneva-based agency, 239 scientists in 32 countries outlined the evidence they say shows that smaller exhaled particles can infect people who inhale them, the newspaper said on Saturday.

Because those smaller particles can linger in the air longer, the scientists - who plan to publish their findings in a scientific journal this week - are urging WHO to update its guidance, the Times said.

"We are aware of the article and are reviewing its contents with our technical experts," WHO spokesman Tarik Jasarevic said in an email reply on Monday to a Reuters request for comment.

The extent to which the coronavirus can be spread by the so-called airborne or aerosol route - as opposed to by larger droplets in coughs and sneezes - remains disputed.

Any change in the WHO's assessment of the risk of transmission could affect its current advice on keeping one-metre physical distancing. Governments, which also rely on the agency for guidance policy, may also have to adjust public health measures aimed at curbing the spread of the virus.

"Especially in the last couple of months, we have been stating several times that we consider airborne transmission as possible but certainly not supported by solid or even clear evidence," Benedetta Allegranzi, the WHO's technical lead for infection prevention and control, was quoted as saying in the New York Times.

WHO guidance to health workers, dated June 29, says that SARS-CoV-2, the virus that causes Covid-19, is primarily transmitted between people through respiratory droplets and on surfaces.

But airborne transmission via smaller particles is possible in some circumstances, such as when performing intubation and aerosol-generating procedures, it says.

Medical workers performing such procedures should wear heavy-duty N95 respiratory masks and other protective equipment in an adequately ventilated room, the WHO says.

Officials at South Korea's Centers for Disease Control said on Monday they were continuing to discuss various issues about Covid-19, including the possible airborne transmission. They said more investigations and evidence were needed.

London, Jul 2: The World Health Organisation says smoking is linked to a higher risk of severe illness and death from the coronavirus in hospitalised patients, although it was unable to specify exactly how much greater those risks might be.

In a scientific brief published this week, the U.N. health agency reviewed 34 published studies on the association between smoking and Covid-19, including the probability of infection, hospitalisation, severity of disease and death.

WHO noted that smokers represent up to 18% of hospitalised coronavirus patients and that there appeared to be a significant link between whether or not patients smoked and the severity of disease they suffered, the type of hospital interventions required and patients' risk of dying.

In April, French researchers released a small study suggesting smokers were at less risk of catching Covid-19 and planned to test nicotine patches on patients and health workers — but their findings were questioned by many scientists at the time who cited the lack of definitive data.

WHO says "the available evidence suggests that smoking is associated with increased severity of disease and death in hospitalized Covid-19 patients. It recommends that smokers quit.
