There’s microplastic in that table salt

Quartz: “A study published Tuesday (Oct. 16) in the journal Environmental Science and Technology found microplastics in more than 90% of the packaged food-grade salt—also known as table salt—for sale in stores. The team, from South Korea’s Incheon National University and Greenpeace East Asia, sampled 39 brands of salt harvested in 21 countries. Only three of the samples had no detectable microplastics. Microplastics are virtually everywhere. Sea salt and lake salt are made by evaporating water and harvesting the salt that remains. Plastic waste flows from rivers into those bodies of water, so it’s no surprise that the salt contains traces of it too. Scientists have been finding microplastics in salt for years, including in salt from China, Spain, and eight countries in Asia, Europe, and Africa. But the latest study goes a step further, finding that looking at where the salt was produced is a good indicator of how much plastic pollution is coming from that particular region…”
