  1. Passive sampling of phosphate with DGT

  2. Diffusive Gradient in thin films (DGT) • Developed for passive sampling of labile metal ions in aquatic environments • Diffusion theory for calculations of time-averaged concentrations. • Main focus: heavy metals Cu, Zn, Cd, Pb, Ni and Cr plus reactive trace metals Mn and Fe. • Chelex, adsorbent for metals • Few studies on collection of anionic compounds. • 2004 studies were preformed by NIVA on DGT as passive sampler for phosphate, arsenate and selnate.
