Two constructed wetlands for treating industrial and sewage effluents (CW1 and CW2) and two natural wetlands (NW1 and NW2), located in Argentina, were studied. The aims of the study were (1) to assess the accumulation and distribution pattern of P in the surface sediments of both natural and constructed wetlands, and (2) to evaluate P long-term retention in sediment. In the sediment of all study sites,...
Phosphorus nuclear magnetic resonance ( 31 P-NMR) spectroscopy has advanced our knowledge of organic phosphorus (P) in soils and environmental samples more than any other technique. This paper reviews the use of 31 P-NMR spectroscopy for soil, water and other environmental samples. The requirements for a successful solid-state or solution 31 P-NMR experiment are described,...
