Division of Environmental Hygiene


The Division coordinates and organises air pollution monitoring carried out by the County Public Health Institutes of the Republic of Croatia.

Sulphur dioxide and smoke are 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’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.


Pesticide and other organic compound analysis in environmental and biological samples, waste materials and other matrices. Determination of human exposure to pesticides and associated compounds.

Specific chemical analysis:

  • organochlorine pesticides and polychlorinated biphenyls in air, suspended particulate matter, surface, ground, drinking and waste waters, soil/sediments, vegetation (leaves and coniferous trees), fat tissue, milk and blood;
  • triazine pesticides and products of their decomposition in surface, ground, drinking and waste waters, soil and sediments;
  • organophosphorus pesticides, urea-herbicides, chlorophenols and other pesticide compounds in surface, ground, drinking and waste waters;
  • polychlorinated biphenyls in oil derivatives, waste oils and similar waste materials;
  • original compounds and characteristic metabolites in human milk, blood and urine as indicators of human exposure to organochlorine pesticides and polychlorinated biphenyls, organophosphorus and triazine pesticides; chlorophenols and compounds that metabolise into chlorophenols.
