Sea Salt Contaminated By Plastic

Sea Salt Contaminated By Plastic.

Sea salt is produced from the evaporation of seawater, rather than by being extracted from sedimentary deposits. It is also called bay salt or solar salt. Like mineral salt, production of sea salt has been dated to prehistoric times. The evaporation of seawater is the production method of choice in marine countries with high evaporation and low precipitation rates. Salt evaporation ponds are filled from the ocean and salt crystals can be harvested as the water dries up. Sometimes these ponds have vivid colours, as some species of algae and other micro-organisms thrive in conditions of high salinity. However, there is little or no health benefit to using sea salt over other forms of sodium chloride salts. Seawater has a salinity of approximately 3.5%. This means that there are about 35 grams (1.2 oz) of dissolved salts, predominantly sodium and chloride ions, per kilogram (2.2 lbs) of water. It is reasonable to assume then since our oceans are laden with discarded plastic products that anything we derived from the seas as part of our food-chain will similarly be contaminated with plastic.
