Salt samples from 21 countries in Europe, North and South America, Africa, and Asia were analyzed. The three brands that did not contain microplastics are from Taiwan (refined sea salt), China (refined rock salt), and France (unrefined sea salt produced by solar evaporation). The study was published this month in the journal Environmental Science & Technology.
In another indicator of the geographic density of plastic pollution, microplastics levels were highest in sea salt, followed by lake salt and then rock salt.
Microplastics found in 90 percent of table salt: potential health impacts?
