Aquatic toxicologist Ali Karami and his team from the Universiti Putra Malaysia studied 16 brands of sea salt from eight different countries including Malaysia, Australia, South Africa, France, Iran, Japan, Portugal and New Zealand. Their findings were published in the journal Scientific Reports.
After dissolving and filtering the salts in their lab, the researchers found 72 particles of contaminants —most of which were identified as plastics, or pigments that may have once been plastic —in 15 of the brands. While the salt from France was not contaminated with plastic, the others contained between one to 10 particles per kilogram of salt.
The report says:
Back in 2015, a similar study in China found micro plastics in salt purchased in supermarkets there.
The concentration of plastic in sea salt is low enough that they do not present a concern for human health at present. But if plastic pollution continues unabated, those levels may increase and potentially become detrimental to human well-being.
Plastics are estimated to represent almost 80 percent of the total marine debris floating in the world's oceans. It is now believed that there are 5.25 trillion pieces of plastic debris in the ocean.
