Phosphorus (P) is an indispensable element for all life on Earth and, during the past decade,
concerns about the future of its global supply have stimulated much research on soil P and …

Phosphorus (P) is an essential element for all life forms, and P-availability thus an important
driver of a functioning agriculture. However, phosphate rock resources for P-fertilizer …

Environmental context It is now nearly 20 years since the introduction of the technique of
diffusive gradients in thin films, which can provide information on solute concentrations and …

Hydrogels are increasingly being used to control mass transport in the analytical
determination of trace elements. Quantitative use of the techniques of diffusive gradients in …

Dredging and in situ adsorbent inactivation are two methods which are frequently used in
eutrophic water bodies such as ponds, lakes and estuaries to control internal phosphorus …

The Equilibrium Phosphorus Concentration (EPC0) of river bed sediments has been
measured for a wide range of agricultural subcatchments and main river sites across two …

The increasing appreciation of the small-scale (sub-mm) heterogeneity of biogeochemical
processes in sediments, wetlands and soils has led to the development of several methods …

The emerging technique of DGT (diffusive gradients in thin films) is shown to be capable of
performing new speciation measurements in situ in natural waters. In DGT, metals are …

A large number of ex situ sampling techniques have been used traditionally to investigate
the impact and fate of pollutants in soil, sediment and waters. However, the distribution and …

Environmental context. Total concentrations of mineral elements in soil bear little relation to
their availability for plants. The DGT (diffusive gradients in thin-films) technique has been …
