Plastic Found in 83% Drinking Water on Five Continents, Nobody is Safe

While the health impact of ingesting plastics are unclear, it is not something you would want to consume

  • Tiny particles of degraded plastic called microplastics found in drinking water
  • Consumption of microplastics by fishes are known to stunt growth, inhibit hatching of eggs and increase mortality rates
  • The tiny pieces of plastic have been found in both, public taps and bottled water

London, September 7, 2017 : Tiny pieces of plastic have been found in drinking water on five continents – from Trump Tower in New York to a public tap on the shores of Lake Victoria in Uganda – posing a potential risk to people’s health, researchers said on Wednesday.

Plastic degrades over time into tiny particles known as microplastics, which were found in 83 percent of samples from Germany to Cuba to Lebanon analyzed by U.S.-based digital news organization Orb Media.

“If you ask people whether they want to be eating or drinking plastic, they just say, ‘No, that’s a dumb question,’ ” said Sherri Mason, one of study’s authors and a chemistry professor at the State University of New York.

“It’s probably not something that we want to be ingesting, but we are, whether through our drinking water, through beer, juice. It’s in our food, sea salt, mussels. Nobody is safe,” she told the Thomson Reuters Foundation.

Microplastics of up to 5 millimeters are also in bottled water, she said.

The health impact of ingesting plastics are unclear, but studies on fish have shown they inhibit hatching of fertilized eggs, stunt growth and make them more susceptible to predators, increasing mortality rates.

Microplastics absorb toxic chemicals from the marine environment, which are released into the bodies of fish and mammals who consume them, Orb Media’s chief executive, Molly Bingham, said in a statement.

While many studies have shown the prevalence of microplastics in the world’s oceans, where more than 5 trillion pieces of plastic are floating, it is the first time research has been conducted into drinking water. (VOA)

Here’s How Belly Fat Increases the Risk of Heart Attack

Belly fat may lead to multiple heart attacks

Heart patients, please take note, here’s a new health news. Researchers have found that heart attack survivors who carry excess fat around their waist are at increased risk of another heart attack.

“Abdominal obesity not only increases your risk for a first heart attack or stroke, but also the risk for recurrent events after the first misfortune,” said study author Hanieh Mohammadi from the Karolinska Institute in Sweden.

Prior studies have shown that abdominal obesity is an important risk factor for having a first heart attack. But until now, the association between abdominal obesity and the risk of a subsequent heart attack or stroke was unknown.

The research, published in the European Journal of Preventive Cardiology, followed more than 22,000 patients after their first heart attack and investigated the relation between abdominal obesity (measured by waist circumference) and the risk for recurrent cardiovascular disease events. The researchers specifically looked at events caused by clogged arteries, such as fatal and non-fatal heart attack and stroke.

Patients were recruited from the nationwide SWEDEHEART registry and followed for a median of 3.8 years. Most patients — 78 per cent of men and 90 per cent of women — had abdominal obesity (waist circumference 94 cm or above for men and 80 cm or above for women).

Increasing abdominal obesity was independently associated with fatal and non-fatal heart attacks and strokes, regardless of other risk factors (such as smoking, diabetes, hypertension, blood pressure, blood lipids and body mass index [BMI]) and secondary prevention treatments. According to the researchers, waist circumference was a more important marker of recurrent events than overall obesity.

The reason abdominal obesity is very common in patients with a first heart attack is that it is closely linked with conditions that accelerate the clogging of arteries through atherosclerosi, the researchers said. These conditions include increased blood pressure, high blood sugar and insulin resistance (diabetes) as well as raised blood lipid levels.

“Our results, however, suggest that there may be other negative mechanisms associated with abdominal obesity that are independent of these risk factors and remain unrecognised,” Mohammadi said.

“In our study, patients with increasing levels of abdominal obesity still had a raised risk for recurrent events despite being on therapies that lower traditional risk factors connected with abdominal obesity such as anti-hypertensives, diabetes medication and lipid lowering drugs,” she added.

According to the study, the relationship between waist circumference and recurrent events was stronger and more linear in men.

“There were three times as many men in the study compared to women, contributing to less statistical power in the female group. Therefore, more studies are needed before definite conclusions can be drawn according to gender,” Mohammadi noted. (IANS)
