Phosphate levels in major basins
Year:
2005
Author:
Philippe Rekacewicz, UNEP/GRID-Arendal
Description:
A comparison of the major watersheds between the two decades showed that Northern Europe and North America had lower phosphate concentrations, while the Ganges and Brahmaputra watersheds in South Central Asia had higher concentrations. Nutrient control programmes in municipal and agricultural activities may be key factors in the observed reductions in phosphate concentrations.
