idrosalina

Idrosalina is a term that appears in some Romance-language scientific writings to denote a saline aqueous medium. It is not a standardized term in international chemistry or hydrology, and its precise meaning can vary by source. Broadly, it can refer to either a saline solution or to a body of water with elevated salinity compared to freshwater.

Etymology and usage sources often trace idrosalina to roots meaning water (idro/hidro) and salty or saline (salina). Because it is not uniformly defined, the term may be used in different contexts to describe either laboratory saline solutions or natural saline environments.

Composition and properties commonly associated with idrosalina include a solution dominated by sodium chloride, with additional ions such as magnesium, calcium, sulfate, and bicarbonate depending on the source. Salinity values described as idrosalina can range from seawater-like levels (around 35 parts per thousand) to hypersaline brines well above that. The higher salinity influences density, freezing point, and electrical conductivity of the medium.

Occurrence and applications vary by context. In natural settings, idrosalina-like descriptions may apply to coastal lagoons, salt flats, saline lakes, and brine pools. In laboratory or medical literature, a saline solution used for experiments or wound irrigation may be labeled as idrosalina in regional or translated texts. Halophilic organisms adapted to high-salt environments may be discussed in ecological studies of idrosalinas, while industrial use covers preservation, processing, and safety considerations related to saline media.
