Study shows 90% table salt is contaminated with microplastics. When we tap 13 million metric tons of plastic into the oceans every year, it will come back and haunt us. And sure enough, it’s doing so in the most vexing way returning as sneaky microplastics, hiding in table salt.
Is there plastic in table salt?
A year ago TreeHugger reported the research that found salt samples from 8 different countries had plastic contaminants from ocean pollution. From a new study has taken a broader look at the problem of plastic in table salt and concludes that it’s even worse.
National Geographic stated that of 39 salt brands tested, 36 had microplastics in them written by Laura Parker, according to the new study by researchers in South Korea and Greenpeace East Asia.
The new research also looks that having the correlation between microplastics in table salt and how predominant it is in the environment where the salt came from. Not surprisingly, they were pretty well related.
A marine science professor at Incheon National University in South Korea Seung-Kyu Kim said. “The findings suggest that human ingestion of microplastics via marine products is strongly related to emissions in a given region.”
Countries effected for microplastics
The 39 samples are from 21 countries in Europe, North and South America, Africa, and Asia. Samples varied in density of the contaminants, but the Asian brands were especially high.
The three salts that were free of plastic are Taiwan, China, and France. Of the three types of salt sampled came from sea, lake, and rock. Sea salt won the prize for highest microplastics levels, next was lake salt and then rock salt.
The new study clams that the average adult consumes approximately 2,000 microplastics per year through salt. Given that the particles are less than five millimeters in size and often the same color of salt. It’s easy for them to infiltrate without notice. Determining the health risks of ingesting microplastics has been tricky so far and nobody has been able to get a scientific conclusion. But suffice to say, at the rates we’re consuming the stuff from our seafood to our table salt. To drinking water even the dust in our homes it can’t be good.
