Summary of yearly research results (15 lines maximum)

Based on the results of the first year of study, namely the hydrogel diffusion studies and modified
o-DGT uptake study, a new passive sampler for polar organics in water has been designed. This
two-sided gel‑gel sampler consists of outer hydrogel layers strengthened by nylon mesh netting and
inner layers of hydrogel with dispersed sorbent, all enclosed between two stainless steel rings.

This sampler has been successfully tested in the field: It can persevere in the river water for up
to 4 weeks, which is enough to obtain environmental concentration levels of ng/l.

In one of the field studies in Rajhrad, the sampler has been deployed alongside POCIS, empore discs
and active composite water sampling. Comparison of performances is yet to be done.

Public lecture in English (delete where appropriate)

                                                                                                                           no



The most important results (5 maximum, show the impact factor of the journal):

                                                 1

Proposed passive sampler has sufficient sampling area, capacity and robustness to be used for
sampling of great spectrum of compounds in the surface waters.

                                                 2

The sampler has been successfully deployed in several sites around the rivers Moravia and Svratka.
