The pink pools in the Dead Sea, what is their secret?

Pictures and videos showed the small pond in pink, while the water a few meters away appeared in its natural form.

Experts explained that this phenomenon often occurs at this time of the year due to high temperatures, especially if the water is highly salty and mixed with fresh water.

In the same context, the appearance of the pink color may be the result of colored secretions from bacteria and algae that prefer a salty environment. The reason is the Dunaliella salina algae, which is active with high water temperature and salinity, and secretes a pink substance that causes water discoloration, which is a widespread phenomenon. In the Sultanate of Oman, China, Ukraine and Senegal.

It is worth noting that Dunaliella salina has unique economic value in food, medicine, health, chemistry and aquaculture, and this algae has achieved industrial production in countries such as Australia and the United States.”
