Researchers at New York University discovered that sea salt contains microplastics. The main culprit is widespread marine plastic pollution.
A year after this discovery, South Korean researchers showed that 90% of the salt used for cooking has tiny pieces of plastic.
A research conducted by the journal Environmental Science & Technology suggests that an adult consumes 2000 microplastics a year.
Unfortunately all this is due to the massive presence of plastics in the oceans and lakes around the world.
Researchers from Incheon National University and Greenpeace East Asia began investigating. They examined 39 brands in 21 countries and thus found microplastics in 36 of them.
The place where salt is most contaminated is Asia. Three of the pollution-free brands are in France, Taiwan and China.

What the studies tell us.
Sherri Mason, the author of the study last year at the State University of New York says: ” The study shows us that microplastics are ubiquitous .” It also indicates that ” Do not think that if you are buying sea salt in England, you are safe .”
Greenpeace East Asia indicates that there is a strong link between the plastic pollution of a place and the amount of microplastics ingested in a year by the inhabitants of that place, without being aware.
Another study places Indonesia in the second highest level of contamination. The vast majority of salt brands from that country were found to contain microplastics.
The executive director of the United Nations Environment Program, Erik Solheim, calls the study terrifying. ” More evidence of the terrifying proliferation of plastic pollution .”
But at the same time he maintains the hope that in addition to these studies, governments and companies will become aware and reduce the use of plastics.
