Organic phosphorus (P) can play a role in in-stream productivity (e.g., periphyton or macrophyte growth), but little is known of the largest likely source of organic P—bed sediment. A survey was conducted of 76 bed sediment samples of rivers within the New Zealand National River Water Quality Network in an effort to determine the concentration and form of organic P species, and variation according to catchment and sediment characteristics or classifications used to characterise anthropogenic P inputs (e.g., as baseline [viz. reference] or impact sites) and therefore likely in-stream productivity....
Some evidence was found of changes in the distribution and form of organic P species in relation to anthropogenic activity and sediment processes. However, organic P concentrations were small and only represented a single sampling. Hence, additional work needs to examine if these changes relate to changes in in-stream productivity over time.
