Environmental Hygiene Unit


The Unit coordinates and organises air pollution monitoring carried out by the County Public Health Institutes of in the Republic of Croatia Jedinica provodi koordinaciju i organizaciju praćenja onečišćenja zraka na području Republike Hrvatske koju provode županijski zavodi za javno zdravstvo, a po potrebi i izobrazba kadrova.

Sulphur dioxide and smoke were measured in Zagreb, Osijek, Rijeka, Sisak, Karlovac, Pula, Labin, Umag, the islands of Krk and Cres, Kutina, Bjelovar, Novska, Kostrena, Kraljevica, Bakar, Opatija, Gorski kotar, Koprivnica, Križevci, Ðurđevac, Našice, Zoljan, Garešnica, Split, Šibenik and Zadar within the scope of the national measuring network. Suspended particles and metals were measured in Zagreb and Rijeka and sediment was measured in Zagreb, Osijek, Sisak, Rijeka, the islands of Krk and Cres, Pula, Labin, Umag, Kutina, Kostrena, Kraljevica, Bakar, Gorski kotar, Bjelovar, Koprivnica, Križevci, Ðurđevac, Karlovac, Donji Miholjac, Novska, Valpovo, Zoljan, Našice, Beli Manastir, Garešnica, Split, Šibenik, Sinj, Makarska, Omiš, and Zadar.

Sulphur dioxide, smoke, suspended particles and Pb, Cd and Mn contained in these, fine particles PM10 and PM2.5 and Pb, Cd and Mn contained in these, nitrogen dioxide and ozone are measured in Zagreb pursuant to a contract with the City Office for Physical Planning, Construction, Housing and Utility Services and Transport. Total sediment and Pb, Cd and TI concentration contained in it have been measured at 9 measuring stations since 1998. At the measuring station at Ksaverska cesta, SO2, NOx and O3 are measured using automatic analysers and conventional methods.

Furthermore, NO2 concentrations are also measured at this measuring station, at two different distances from the road. At one measuring station in Zagreb, polycyclic aromatic hydrocarbons have been measured in suspended particles since 2000. IMROH’s associates have worked on a device for collecting PM10 and PM2.5 suspended particle fractions. Three Zagreb stations are part of the Global Environment Monitoring System (GEMS) coordinated by the World Health Organisation in the scope of the United Nations Environment Programme (UNEP).

The Institute has been coordinating the entire project on the establishment of the state of play at Molve gas field. This project involved analyses of air, water, soil, agricultural and forest ecosystems, and wild game control prior to the commissioning of the Central Gas Station (CGS) Molve III. Coordination is still underway in collaboration with the Public Health Institute of the Koprivnica-Križevci County.

The Environmental Hygiene Unit’s associates have been involved in the monitoring of air quality in the zone of influence of Jakuševec landfill site. Measurements are carried out at three measuring stations; at the northern, western, and southern sides of the remediation working zone. These works are coordinated by Ecoina, Zagreb.


  • air pollution monitoring (sulphur dioxide (SO2), carbon monoxide (CO), ammonium (NH3), ozone (O3), nitrogen oxides (NO, NOx, NO2), hydrogen sulphide (H2S), smoke, fine particles PM10, fine particles PM2.5, lead, cadmium, manganese, arsenic, nickel, polycyclic aromatic hydrocarbons), meteorology and reports.
  • air pollution monitoring in the zone of influence of waste water treatment devices (hydrogen sulphide, ammonium, total mercaptans) and reports.
  • measurement of total sediment and metals in it, as well as in surface soil, reports.
  • measurement of formaldehydes, phenols and ammonia in air in the zone of influence of a stone wool factory, reports.
