This memory has so many cobwebs on it that I can’t remember what the device was called. It was either a washboard or a washing board. Or maybe it even was called something else. (Jumping back to the present, I just checked online and it was a washboard.)
What I do picture clearly is my mother soaping up a shirt and vigorously scrubbing it against this board with metal ridges on it. It made a unique noise. She spent many hours slapping that board until we got our first washing machine.
Years later, even after we got our first clothes dryer, she preferred to hang our laundry on a clothesline in the backyard. I remember bringing frozen shirts into the dryer on more than one occasion.
The invention of the washing machine was a God-send for my mother and women everywhere, but now, eons later, there is a small problem with these ever-evolving devices.
It seems that household washing machines appear to be a major source of so-called “microplastic” pollution — bits of polyester and acrylic smaller than the head of a pin — that scientists now have detected on ocean shorelines worldwide. Their report describing this potentially harmful material was published in ACS’ journal Environmental Science & Technology.
Mark Browne and colleagues explain that the accumulation of microplastic debris in marine environments has raised health and safety concerns. The bits of plastic contain potentially harmful ingredients which go into the bodies of animals and could be transferred to people who consume fish. Ingested microplastic can transfer and persist into their cells for months.
How big is the problem of microplastic contamination? Where are these materials coming from? To answer those questions, the scientists looked for microplastic contamination along 18 coasts around the world and did some detective work to track down a likely source of this contamination.
They found more microplastic on shores in densely populated areas, and identified an important source — wastewater from household washing machines. They point out that more than 1,900 fibers can rinse off of a single garment during a wash cycle, and these fibers look just like the microplastic debris on shorelines.
The problem, they say, is likely to intensify in the future, and the report suggests solutions:
“Designers of clothing and washing machines should consider the need to reduce the release of fibers into wastewater and research is needed to develop methods for removing microplastic from sewage.”
