Set down your mug.

Steeping a single premium teabag in a cup of sizzling water releases billions of plastic microparticles and nanoparticles into your tea.

This disturbing info was found in a examine performed at McGill College in Canada and revealed on September 25, 2019, within the journal of Environmental Science and Expertise.

Researchers bought 4 manufacturers of premium teas, packaged in plastic mesh teabags. Whereas teabags have historically been made from paper, the plastic mesh sort is changing into more and more widespread. Plastic mesh is interesting as a result of it holds a pyramid form, which can assist the tea infuse extra evenly.

The examine at McGill College discovered {that a} single teabag, steeped at a typical brewing temperature (95°C), launched 11.6 billion microparticles and three.1 billion nanoparticles of plastics right into a cup of water. This quantity was mentioned to be “a number of orders of magnitude larger than plastic masses beforehand reported in different meals.”

Wait…plastics in different meals? This raises so many questions. Let’s attempt to reply some.

What are Microplastics?

Microplastics are outlined as tiny particles of plastic which are smaller than 5 millimeters in diameter. That’s in regards to the dimension of a personality on a pc keyboard. Many microplastics are on the order of 100 nanometers, which is in regards to the width of a human hair. Nonetheless others are a thousand occasions smaller and invisible to the bare eye.

Microplastics are ubiquitous within the atmosphere. They’ve been present in rivers, ponds, lakes, and oceans. They’re in freshwater, wastewater, faucet water, bottled water, meals, and even within the air. Microplastics have been detected in locations that vary from the rain over the Rocky Mountains of Colorado to the ocean ice of Antarctica.

Most microplastics come from the breakdown of bigger plastics. Different microplastics are designed by people. Till 2015, tiny items of polyethylene plastics (referred to as microbeads) had been added to toothpastes, exfoliant cleansers, and cosmetics. Microbeads had been banned with the passage of the Microbead-Free Waters Act of  2015.

Due to such intensive environmental contamination with plastic, folks and different animals eat microplastics each day. In a examine revealed in January of 2019, researchers examined 50 marine animals alongside Britain’s shores. They discovered that each single animal discovered lifeless alongside the coast—together with dolphins, seals, and whales—had ingested microplastics and had them inside their digestive tracts.

What Meals Include Microplastics?

Bottled waters lead the pack for contamination with microplastics. Analysis led by Orb Media and performed on the State College of New York at Fredonia evaluated 250 bottles of water from 11 main bottled water manufacturers from 9 nations world wide.

The examine discovered that 93% of the bottles confirmed indicators of microplastic contamination. Though some bottles of water had no detectable plastic, different bottles had 1000’s. The general common throughout all manufacturers was 325 plastic particles per liter of bottled water.

Bottled water apart, research have detected microplastics in seafood, honey, salt, sugar, and beer. In a evaluate of research that was revealed in June of 2019, researchers estimated that Individuals eat between 39,000 and 52,000 particles of plastic from meals annually. Listed below are some widespread sources of plastics in meals:

  • Canned Meals. Meals cans are generally lined with bisphenol-A (BPA), which is a plastic that may leech into the meals.
  • Plastic Packaging. Take into consideration all of the meals you purchase which are wrapped, packaged, or contained in plastic. There are frozen meals, take-out meals, ready salads, meats, cheese, crackers, and cereal. How a lot plastic leeches into the meals in these packaging remains to be up for debate.
  • Desk Salt. Contemplating that our oceans are contaminated with plastics, it’s no shock that our salt is simply too. Sourcing salt from extra pristine areas of the world is likely to be the easiest way to reduce plastic publicity from salt.
  • Beer. Research have discovered that microplastics contaminate not less than 12 manufacturers of American beer—possible due to the faucet water used to brew the beer.
  • Fish and Hen. Most research have solely seemed for microplastics within the digestive tracts of marine animals. Nonetheless, there may be some proof that these microplastics make their means into the fish we eat. Microplastics have additionally been detected in chickens raised in gardens in Mexico.

Microplastics are usually not regulated in bottled water or meals. There aren’t any set limits and no routine monitoring for contamination.

Do Microplastics Have an effect on Well being?

After Orb Media discovered microplastics in most bottled waters, the World Well being Group launched an initiative to find out whether or not these plastics pose any danger to human well being. Within the report launched in August of 2019, WHO said the next:

“The human well being danger from microplastics in drinking-water is a operate of each hazard and publicity. Potential hazards related to microplastics are available three types: the particles themselves which current a bodily hazard, chemical substances (unbound monomers, components, and sorbed chemical substances from the atmosphere), and microorganisms which will connect and colonize on microplastics, referred to as biofilms. Based mostly on the restricted proof out there, chemical substances and microbial pathogens related to microplastics in drinking-water pose a low concern for human well being. Though there may be inadequate info to attract agency conclusions on the toxicity of nanoparticles, no dependable info suggests it’s a concern.”

This assertion might not be sufficient to alleviate your worries in regards to the well being results of microplastics. There are nonetheless many unanswered questions. We don’t totally perceive the place these particles accumulate within the physique or what methods they have an effect on. There’s proof that BPA disrupts endocrine operate and different plastics might have an effect on immune well being.

How Can I Keep away from Microplastics?

In brief—you may’t. Microplastics are an environmental contaminant that you simply can not totally keep away from. Nonetheless, you may take steps to reduce your publicity:

  • Carry your individual container to take leftovers dwelling from eating places
  • Cook dinner from scratch quite than buying pre-packaged meals
  • Develop your individual greens are buy from a Farmer’s Market or CSA to reduce plastic luggage and packaging
  • Buy meals like grains and nuts from the majority part quite than in plastic packaging
  • Select canned meals which have BPA-free lining
  • Keep away from shopping for frozen meals as a result of most are packaged in plastic
  • Make your individual fresh-squeezed juice quite than shopping for it in plastic bottles
  • Use a reusable glass water bottle quite than disposable plastic water bottles
  • Keep away from microwaving in plastic
  • Retailer meals in glass quite than plastic

Along with minimizing your private publicity to microplastics, you can too take measures to lower the burden of plastic air pollution on the earth. You make selections each day within the merchandise you buy, use, and throw away.

The invention that premium teabags leech plastic particles into your cup of tea is only a small piece of the puzzle. Let’s take it as a reminder that we have to be aware each day about our selections for our well being, our vitamin, and our planet.
