Korean scientists found microplastic in 36 of 39 samples of salt.

And the largest number of particles of microplastics, according to experts, is contained in sea salt: this is due to water pollution with plastic waste..

About 300 million tons of plastic are produced annually in the world, and most of it is not processed. Because of this, a significant proportion of plastic trash accumulates in the oceans.. According to the latest estimates, one of the largest garbage spots in the Pacific Ocean contains from 5 to 20 thousand tons of plastic..

Plastic debris and microparticles of plastic are often found in marine organisms, thereby increasing the likelihood that it enters the human body. Food salt (sodium chloride) of natural origin is extracted by natural evaporation of sea water from caverns: therefore, it is assumed that plastic can be in it. Scientists analyzed samples of 39 commercially available types of salt, of which 28 are sea salt brands.

The largest amount of microplastics was found in salt produced in Asian countries:

for example, about 13,629 particles of micropaste were found in a kilogram of one of the samples of sea edible salt produced in Indonesia. However, it is not yet known how microplastic content in salt affects people's health..

According to the latest data obtained in April of this year, several million plastic particles can be contained in a single cubic meter of arctic ice.. This figure has increased a thousand times over four years..
