Over 90% of sampled salt brands globally has been found to contain microplastics, with the highest number coming from salt sourced in Asia, according to a new study co-designed by Kim, Seung-Kyu, Professor at Incheon National University and Greenpeace (www.Greenpeace.org) East Asia.
The study, which has been published in Environmental Science & Technology, a peer-reviewed scientific journal, analyzed 39 various salt brands globally, showing that plastic contamination in sea salt was highest, followed by lake salt, then rock salt – an indicator of the levels of plastic pollution in the areas where the salt was sourced.
Only three of the salt brands studied did not contain any microplastic particles in the replicated samples.
“Recent studies have found plastics in seafood, wildlife, tap water, and now in salt. It’s clear that there is no escape from this plastic crisis, especially as it continues to leak into our waterways and oceans,” said West Africa Oceans Campaigner at Greenpeace Africa Awa Traoré, adding, “We need to stop plastic pollution at its source and therefore call upon the accountability of big corporates in this crisis. They need to reduce their plastic footprint and take on the problem they have created.”
He said the effective implementation of single use plastics ban laws in African countries should be seen and not only strong commitments from governments.
“For the health of people and our environment, it’s incredibly important that these big corporates be pushed to go beyond recycling, start taking responsibility for their contribution to plastic pollution and begin reducing single-use plastic production,” he said.
