Sažetak
Total deposited matter (TDM) or bulk deposition is defined as the total dry and wet fallout collected in a container placed in an open field. It is consisted of substances in solid, liquid and gaseous phases which accumulate on the ground by gravity (dry deposition) or precipitation (wet deposition) from the atmosphere and contaminate soil, vegetation, materials and indirectly affect people. Trace metals spread both from anthropogenic (industrial emissions, civil heating system, vehicular traffic) and natural sources (soil dust, sea spray, volcanic activity). Monthly samples of bulk deposition were collected over a one-year period at two sampling sites, Mukinje and Homoljac, in national park Plitvice lakes, Croatia. Bergerhoff samplers were used to collect bulk deposition. Samples of bulk deposition were analyzed for metals (Ni, As, Cd, Pb) by inductively coupled plasma mass spectrometry (ICP MS). The lowest value of deposition fluxes for Ni, As and Cd was found at Mukinje sampling site: 0, 63 μg/m2d, 0, 04 μg/m2d and 0, 02 μg/m2d, respectively. The lowest value of deposition flux for Pb (0, 05 μg/m2d) was found at Homoljac sampling site. The highest value of deposition fluxes for Ni, As, and Pb was found at Mukinje sampling site: 3, 02 μg/m2d, 1, 41 μg/m2d and 6, 74 μg/m2d, respectively. The highest value of deposition flux for Cd (1, 46 μg/m2d) was found at Homoljac sampling site. Deposition fluxes of metals were below the limit values set by the Croatian air protection legislation.
