Sažetak
Croatia participated for the first time in moss survey in 2005, in the framework of the International Cooperative Programme on Effects of Air Pollution on Natural Vegetation and Crops with heavy metals in Europe (UNECE ICP Vegetation) when different species of moss samples (Hypnum cupressiforme, Pleurozium schreberi, Brachythecium rutabulum and Homalothecium sericeum) were collected from 96 locations evenly distributed over the country. An additional 27 new sampling sites were added for the investigation in 2010. Moss samples were collected during the summer and autumn of 2010. Collected moss samples were air dried, cleaned and totally digested by using microwave digestion system. Digests were analysed for cadmium by atomic emission spectrometry with inductively coupled plasma (ICP-AES). The results for cadmium were compared with the results obtained in previous investigations in Croatia and some other neighboring countries and Norway as a pristine area. The content of cadmium ranges from 0.10 mg kg-1 to 1.42 mg kg-1. It was found that the median value of cadmium (0.38 mg kg-1) is 1.41 times higher than the value obtained in the study performed in 2005. Compared to the other countries, Croatia shows insignificantly higher median value. Highest contents of cadmium were found in the Podravina region (1.14 mg kg-1 and 1.42 mg kg-1) where cadmium inputs as a result of anthropogenic origin from Slovenia and Austria (Pb and Zn mines and smelter plants). High levels of cadmium were also found in moss samples collected at some industrialized areas in northern parts of Croatia as a result of anthropogenic influence as well as in samples collected in the Coastal region where high levels are a result of geological origin.
