Environment > Water > Dissolved oxygen concentration: Countries Compared

DEFINITION: Dissolved oxygen concentration
Units: Milligrams/Liter
Units: The country values represent averages of the station-level values for the three year time period 1994-96, exceptwhere data were only available for an earlier time period (1988-1993). The number of stations per country varies depending on country size; number of bodies of water; and level of participation in the GEMS monitoring system. The data from "The Wellbeing of Nations" included a smaller subset of stations representing outfalls of major watersheds. An analysis of a sample of countries with numerous stations found that the data for stations in the subset is broadly comparable to the data for all GEMS stations in those countries.
