United Nations Environment Programme (UNEP), Global Environmental Monitoring System/Water Quality Monitoring System, with data for an additional 29 countries from Prescott-Allen, R. The Well being of Nations, Washington, DC: Island Press, 2001

DEFINITION
Suspended solids
Units: Natural Log of 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. Data from "The Wellbeing of Nations" included a smaller subset of stations representing outfalls of majorwatersheds. 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. The data in this table was transformed using the natural logarithm.
