Microplastics & table salt: worse than we thought

by Trevor Russell

A recent article from National Geographic highlights some unfortunate news on microplastics in table salt.

New research found microplastics in 90% of salt samples from 21 countries in Europe, North and South America, Africa, and Asia.

We’ve long known that somewhere between 4.8 and 12.7 million metric tons of plastic is flowing into our oceans each year, where they break down into smaller and smaller pieces that work their way up the food chain with chemical and physical consequences for aquatic life.

Unknown, to date, is just how widespread human exposure to microplastics may be and their potential health consequences.

These most recent survey results suggest microplastic exposure, at least from the world's most common seasoning, is likely high.
