Summary:
The highest level of plastic contamination was found in salt sourced from the ocean. The researchers measured more than 250 particles of plastic per lb of sea salt. Given that manufacturers typically extract sea salt from ocean water by evaporation—a process that leaves everything behind but water —microplastic contamination of sea salt is likely prevalent outside China as well. Plastics have become such a ubiquitous contaminant, I doubt it matters whether you look for plastic in sea salt on Chinese or American supermarket shelves. I’d like to see some ‘metoo’ studies. Given that there are heavy metals and other chemicals of concern in plastic pollution, it’s wise to minimize the entry of plastic into the food chain. People argue that plastic contamination originates from the vast amount of plastic pollution floating around marine environments where sea salt is sourced. The researchers add that other points of entry for plastic contamination are also possible, including during salt processing, drying, and packaging.

Reflection:
People realize that most of the contamination comes from the ocean. I think the reason why for that is dumping garbage and trash into the ocean is the fastest and easiest way to process, because all people need to do is just one step. Especially, the plastics in modern life, people use it every single day, thus, there is a large amount of plastics end up going to the trash can, therefore, it creates plastic pollution.
