Detailed explanation-1: -Salinity is the total weight of dissolved solids, in grams, found in one kilogram of seawater and may be determined from the concentration of chlorinity because of the constancy of major constituents.

Detailed explanation-2: -The dissolved solids concentration in water is the sum of all the substances, organic and inorganic, dissolved in water. This also is referred to as “total dissolved solids”, or TDS.

Detailed explanation-3: -Total dissolved solids (TDS) is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular (colloidal sol) suspended form. TDS concentrations are often reported in parts per million (ppm).

Detailed explanation-4: -Total solids are dissolved solids plus suspended and settleable solids in water. In stream water, dissolved solids consist of calcium, chlorides, nitrate, phosphorus, iron, sulfur, and other ions particles that will pass through a filter with pores of around 2 microns (0.002 cm) in size.
