I. STUDY ON PHOSPHOROUS CONTENT AND DISTRIBUTION Nutrient pollution of surface waters is a challenge of the modern society, leading to the occurrence of the eutrophication phenomenon which limits the uses of the aquatic resources for various purposes. The aim of this study was the evaluation of water and sediment status of the Plumbuita Lake (Bucharest-Romania), focusing on phosphorous speciation (phosphorous bonded to iron and aluminium, phosphorous bonded to calcium, and soluble and loosely sorbed phosphorous bonded to carbonate) and dynamics as this element has a significant contribution to algal bloom. The results reported herein will allow the understanding and control of the processes that take place within the water body and support the appropriate techniques for the mitigation of water polluted mitigation with phosphorus-based compounds.
