Study sheds light on human consumption of microplastics

A study from the University of Victoria has for the first time compiled research on microplastics to try to estimate just how much people are consuming.

June 1, 2019

Microplastics are pieces of plastic that are just under five millimetres in diameter — or smaller than the size of a sesame seed — that come from the degradation of larger plastic products or the shedding of particles from water bottles, plastic packaging and synthetic clothes.

Garth Covernton, a PhD candidate at University of Victoria’s department of biology, said his team looked at 26 papers assessing the amount of microplastics found in individual food items.

The study found that a person’s average microplastic consumption — based on those food items previously analyzed — would likely be somewhere between 70,000 and 121,000 particles per year. While younger girls were at the lower end of the spectrum, adult men were at the high end.

People who consume a lot of bottled water could see that number jump by up to 100,000 particles per year.

The study analyzed the amount of microplastics found in fish, shellfish, sugars, salts, alcohol, water and air, which account for 15 per cent of Americans’ caloric intake.

But the other 85 per cent of what people consume, like beef, poultry, dairy and grains, has still not been examined.

Covernton compared the study to early understandings of cigarettes and tobacco: While the numbers they came up with did seem large, they don’t yet know exactly what level of consumption is dangerous.

“We’re at the point where we know microplastics at some dose could be harmful, but we’re not at the point where we can say whether what the average person is encountering is the equivalent of one cigarette in a lifetime, or that chronic exposure, like a pack a day.”

Covernton said the findings demonstrate more work needs to be done to understand how the tiny particles might affect human health. (CBC)

K-Cup creator John Sylvan regrets inventing Keurig coffee pod system

K-Cup creator John Sylvan regrets inventing Keurig coffee pod systemThe man who invented the K-Cup coffee pod almost 20 years ago says he regrets doing so, and he can’t understand the popularity of the products that critics decry as an environmental catastrophe.

July 29, 2014

John Sylvan worked at Keurig in the 1990s when he devised a simple product that could create a small mug of coffee out of a plastic pod. Originally aiming it at office workers, Sylvan said he thought the product might have some limited appeal to people who would normally go Starbucks, Dunkin Donuts or other coffee chains in the morning, because now they could get a cup of coffee at work that was cheaper, faster, and no fuss.

“That would make it environmentally neutral, because you wouldn’t have those Starbucks cups [everywhere],” Sylvan told the CBC’s As It Happens in an interview. “The first market was the office coffee service market,” he said, adding he is “absolutely mystified” by his product’s popularity in homes.

Popularity doesn’t begin to describe it, as the K-Cup’s status is closer to ubiquity. Keurig Green Mountain’s annual revenues have climbed to almost $5 billion, up more than five-fold in five years, largely on the back of selling billions of K-Cups every year.

Keurig dominates what’s come to be a large and growing market. Research firm NPD Group recently estimated that about 40 per cent of Canadian homes have a single-serving coffee machine, and Canadians spent $95 million on them last year.

According to a wildly popular ad campaign against the product earlier this year, there are so many discarded K-Cups that if you lined them up it would be enough to circle the earth more than 10 times — and that’s just from one year’s worth of coffee pods.

As the man who invented them, Sylvan might have been pleased with their popularity. But he left the company in 1997, selling his ownership of the product for $50,000.

To this day, he still doesn’t understand why people like them. “I find them rather expensive,” he said. (Source: CBC News)
