JDS4 started in Hungary with the official kick-off for JDS4 together with first microplastic sampling on 27th June in Budapest, organised by the Hungarian Ministry of Interior (BM) and the General Directorate of Water Management (OVF).

The event included series of introductory talks, presentations, and a press conference in the presence of the Deputy Mayor of Budapest and the Hungarian Deputy State Secretary for the Interior, along with ICPDR president, Péter Kovács, plus ICPDR Executive Secretary Ivan Zavadsky and JDS4 co-ordinator, Igor Liska.
