Ten parts per billion (ppb) refers to a concentration measurement indicating that there are 10 units of a substance for every billion units of the total solution or mixture. In terms of weight, this means 10 micrograms of a substance in one liter of water (since one liter of water is approximately one billion micrograms). This measurement is often used in environmental science, toxicology, and chemistry to express very low concentrations of pollutants or chemicals.

No, the salinity of the Red Sea is not often below 10 parts per thousand. In fact, the Red Sea is known for its high salinity, typically ranging from about 36 to 41 parts per thousand. Factors such as evaporation and limited freshwater inflow contribute to this elevated salinity. It is generally much higher than the threshold of 10 parts per thousand.
