A nurdle is a bead of pure plastic. It is the basic building block of almost all plastic products, like some sort of synthetic ore; their creators call them “pre-production plastic pellets” or “resins.” Every year, trillions of nurdles are produced from natural gas or oil, shipped to factories around the world, and then melted and poured into molds that churn out water bottles and sewage pipes and steering wheels and the millions of other plastic products we use every day. You are almost certainly reading this story on a device that is part nurdle….
An estimated 200,000 metric tons of nurdles make their way into oceans annually. The beads are extremely light, around 20 milligrams each. That means, under current conditions, approximately 10 trillion nurdles are projected to infiltrate marine ecosystems around the world each year.
Hundreds of fish species — including some eaten by humans — and at least 80 kinds of seabirds eat plastics. Researchers are concerned that animals that eat nurdles risk blocking their digestive tracts and starving to death. Just as concerning is what happens to the beads in the long term: Like most plastics, they do not biodegrade, but they do deteriorate over time, forming the second-largest source of ocean microplastics after tire dust. (A nurdle, being less than 5 millimeters around, is a microplastic from the moment of its creation, something also known as a primary microplastic.)
There’s much we still don’t know about how plastics can harm the bodies of humans and animals alike, but recent research has shown that microplastics can be found in the blood of as much as 80 percent of all adult humans, where they can potentially harm our cells. We may not eat the plastic beads ourselves, but nurdles seem to have a way of finding their way back to us.
You could always write to your Congress-critter and complain. If they fit the average profile, they might ask you to explain what a nurdle is. The only reason I know is because I spent a few strange years – long ago and far away – running a production quality lab for a plastics manufacturer. :-]
No doubt, your elected buddy is on the donations payroll from plastic manufacturers who offer a helluva lot more to their re-election than you or I do.
