Currents of Change is a CBC series exploring the single-use plastic we’re discarding, and why we need to thoroughly up our act. You can be part of the community discussion by joining our Facebook group.

Krista Beardy passes her days digging in the mud along the Bay of Fundy shoreline, looking for clams and mussels that she whim test for the presence of microplastics.

The 43-year-old graduate student in biology at the University of New Brunswick in Saint John was spark off to start her research after more than a decade as a kayaking orientate and instructor.

Whenever she was on the water, Beardy ​found the amount of trash «confusing,» especially after a large storm.

«Where did all of this take place from? This all couldn’t come off of boats. Is this blowing off the get? Is this inadequate landfill issues? It was just immense amounts of junk making its way into the ocean so that’s kind of what inspired me to start this.»

Beardy’s microplastics over focuses on clam and mussel species found on the beaches on the New Brunswick side of the Bay of Fundy, and she expects to expand her research to the Nova Scotia side in 2019.

Her preliminary results set «plastic contamination» in the flesh of every clam she collected.

Beardy «summaries» the tissue or «biological material» of the clams using an alkaline solution that bequeaths behind only the microplastics.

«Whether that’s four or five sketches or up to 14 for one clam that I digested — and there doesn’t seem to be a wisdom or reason about where the ones that were more influentially infected with plastic are,» she said.

Beardy is also concentrating samples of the sediment, or mud, that is directly beside the clams, and documenting the surviving strategies of the different species.

«Some of the them are filter feeders and some of them are moratorium and deposit-feeding bivalves, and I want to see what kind of feeding strategies are at high-class risk of uptake of microplastics in their diet.»

The microplastics Beardy is conclusion are «teeny, tiny» and not visible to the naked eye.

Holding a soft shell clam that she’s principled dug up, Beardy will drop it in a triple-rinsed glass jar and put it in her freezer until she is given to search the sample in her lab for microplastics.

«Most of it looks like tiny attach attract, but there are some little round pieces, there are some photographs — like plastic bags.»

Beardy doesn’t expect ingesting these microscopic shreds of plastic will hurt humans, because the pieces are too small to bring on any obstructions.

«It usually passes through our system and, in fact, the plastic itself is biologically idle. It’s not going to obstruct our stomachs.»

Other Canadian research underway

Heather Explore, a marine ecologist and professor in the department of biological sciences at UNB in Saint John, is Beardy’s speculative supervisor.

She said the presence of microplastics is an environmental issue that’s engaging more and more attention.

«We’re still at the stage of figuring out where they are, how much there is — all of that kind-hearted of basic stuff that we need to know about them previous we can figure out how much of an impact they’re having on organisms or potentially sober-sided on people.»

Hunt doesn’t think the discovery of microplastics in local clams is something to «unforeseen out about.»

Heather Hunt, a professor at UNB Saint John and academic director to Beardy, said microplastics have likely been in our clams ‘for some habits.’ (Twitter)

«If they are there in the clams, they’ve been there for some conditions,» she said.

This research project, and many others taking correct position across the country, aim to identify where microplastics are being found.

In a dispatch release, Fisheries and Oceans Canada said the results of research being done across Canada choose help «inform future decisions about how to protect and use our marine freshwater atmospheres.»

‘It makes me feel helpless’

On a secluded beach on Berry Point, numberless than 100 kilometres from Saint John and more than 10 km from Saint  Andrews, you can see hundreds of compositions of trash — all of it plastic.

If you look quickly, it doesn’t look as though there is that much chintzy garbage on this beach but a closer examination turns up dozens of crummy bands from lobster fishing and even more bits and sections of plastic rope. (Vanessa Blanch/CBC)

There are large feed bags, coarse plastic garbage bags, pieces of rope and dozens of elastic platoons used to keep lobster claws closed.

As part of her research, Beardy is reputation the amount of plastic on various beaches, and how it compares with the level of shapable contamination in the surrounding sediment, clams and mussels.

Beardy said the amount of slag on this day «isn’t too bad» but warned that when winter comes, it «gets undeniably disgusting.»

The closer you look at the wet piles of golden seaweed, the more remnants of plastic you see.

«It’s just layers and layers of rope,» she said.

«If you were to dig in the course this seaweed you can see some blue rope there, some more dismal rope there, and these things here — that strap cardboard together — atmosphere how tough that is. That does not break up. That is something that anything could swim past and easily get tangled up for life in that.»

At the end of the day, the oceans are one big global conveyor band and it moves everything — including garbage.— Krista Beardy

Holding a Styrofoam channel mark, a bait bag and a plastic six-pack collar that she just picked up, Beardy confessed it is difficile to come back to a secluded beach over and over and see so much bullshit.

«It makes me feel helpless,» she said. «For what everybody’s trying to do and you until this see this in an area that has such a low population.

«You see this and you know that this is a far-reaching problem. You know that it’s not just the local industry and the local in the flesh that are causing it. We’re all at fault, but at the end of the day, the oceans are one big global conveyor belt and it transfers everything — including garbage.»

Look high said the research will consider how far from human activity the microplastic is being organize and will also look at ocean currents.

Only after the baseline learn about is complete can scientists then look at what it means for the larger ecosystem.

«At times we know how much microplastic is there and we know where there’s diverse microplastics, then, I think, is the time we could look more at what are the potential tenors of those microplastics,» Hunt said.

What lies beneath

The amount of synthetic garbage on the shore is «just a small indication» of what is lying underneath the surface of the ocean, according to Beardy.

As plastic becomes contaminated with chemicals and sea mortal starts to attach itself to the surface, it moves down the water column and after all mixes with sediments.

It’s in all of our best interests — emotionally, psychologically and financially, to compensate for sure that the Bay of Fundy stays as beautiful as it can be.— Cynthia Callahan, Huntsman Thalassic Science Centre

«So we are looking at ocean sediments as a place where synthetics are now going to be trapped more so than just up on the beach.»

Plastic that has appropriate for trapped at the bottom of the ocean breaks down much more slowly than responsive that is on the shoreline because it is not exposed to heat or light.

Another bear on for Beardy are the contaminants that are attracted to plastic in the ocean.

While microplastics determination pass through our digestive systems, Beardy worries these particles of plastic could become poisonous.

«My -carat example is DDT,» she said, referring to the pesticide that began being occupied in the late 1940s but was banned a few decades later because of its environmental effects. 

«We haven’t been using [DDT] for a very much long time but it’s still in our environment. It’s those kinds of pesticides, that birth of chemical, that binds to the surface of the plastic, and when it binds to the extrinsically of the plastic it makes the plastic more than just an obstructive young, it makes it a chemical contamination issue.»

Beardy recently discovered what she believed was a decaying bald eagle on a beach on Berry Point, partly buried amongst seaweed and trash.

«I have no way of knowing, of course, if this bald eagle was fatigued as a result of ingestion, as he was badly decomposed, but it was just a strange picture. Vastly sad.»

Cynthia Callahan of the Huntsman Marine Science Centre in Saint Andrews told plastic is destroying habitat for a growing number of species.

«All of these creatures label the Bay of Fundy home, and when man-made objects end up in there, it’s definitely violating on their environment,» she said.

«It’s in all of our best interests — emotionally, psychologically and financially — to turn sure that the Bay of Fundy stays as beautiful as it can be.»

Fishermen quick to aid

Beardy hopes her research will help persuade people to obtain changes to their behaviour so they use less plastic, and the plastic they do use is recycled.

She claimed this is also a way to show industry, including fishermen, whose strand and gear are likely contributors to the plastic pollution, how important it is to keep ersatz trash out of our waters.

«We all want healthy fisheries around here — it’s a big participation of our economy and I for one love fish — and I don’t want to see that on the list of things you can’t eat anymore.»

Beardy said when she deduces her findings to local fishermen, they listen and are «very fast to remedy.»

«I wanted a way to portray to the local fisheries that if we don’t do something and we don’t do something now, there’s not prevailing to be a fishery for the next couple of generations — it’s not going to be the same.»

The CBC’s Vanessa Blanch discovered that microplastics are pronouncement their way into the sediment and the shellfish at the bottom of the Bay of Fundy. She caught up with grad schoolgirl Krista Beardy, just outside St. Andrews. 9:19
