  Anthropogenic phosphorus inputs to a river basin and their impacts on riverine phosphorus fluxes along its upstream-downstream continuum 

  Zhang, W.S.; Swaney, D. P.; Hong, B.; Howarth, R. W. (Wiley, 2017-12-23)

  The increasing trend in riverine phosphorus (P) loads resulting from anthropogenic inputs has gained wide attention because of the well-known role of P in eutrophication. So far, however, there is still limited scientific ...
