According to the abstract of the paper:
A total of 39 different salt brands produced at geospatially different sites, including 28 sea salt brands from 16 countries/regions on six continents, were investigated. A wide range of MP content (in number of MPs per kg of salt; n/kg) was found: 0–1674 n/kg (excluding one outlier of 13 629 n/kg) in sea salts, 0–148 n/kg in rock salt, and 28–462 n/kg in lake salt. Relatively high MP content was identified in sea salts produced in Asian countries/regions. The abundance of MPs in unrefined sea salts ( n = 25) exhibited significant linear correlations with plastic emissions from worldwide rivers ( r 2= 0.33; p = 0.003) and with the MP pollution levels in surrounding seawater ( r 2= 0.46; p = 0.021) in the published literature.
Does that help? (oops, I see @copykate mentioned that first.)
Plastic is in everything now.
The article is headlined as being about drinking water but it also lists other studies showing microplastics in honey, sugar, beer, fish, the air.
Basically everything that has been tested now contains measurable levels of microplastics.
Yup, that’s what the abstract says.
