ICP Vegetation moss survey of urban forests in Zagreb

Since 2005, Croatia has participated in a moss survey within the framework of the International Cooperative Program on Effects of Air Pollution on Natural Vegetation and Crops with heavy metals in Europe (UNECE ICP Vegetation) http://icpvegetation.ceh.ac.uk. In accordance with the sampling strategy of the European moss survey program, moss samples were collected during summer 2006 and summer/autumn 2010 in Croatia on a nearly regular network 23 x 23 km with additional samples around large urban/industrial areas. In the city of Zagreb, four samples were collected. Two of them were samples from regular network and another two were collected in Zagreb parks: Botanical garden and Maksimir Park. Moss samples were collected in forest areas according to ICP Vegetation protocol. Samples were prepared for analytical measurements and analyzed using INAA, ICP-AES and AAS. Comparing results for 10 elements (As, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Zn) collected in Zagreb area, it is clearly seen that concentrations of elements in most cases have the highest values in Botanical garden (center of he city) and lowest in Maksimir Park. Concentrations in natural forests on Medvednica and Vukomericke Gorice are between those two points. The results of measurements in 2006 and 2010, as well as differences are presented and commented in paper. For more precise results of air pollution, further investigation should be done.
