Study of nitrogen pollution in Croatia by moss biomonitoring and Kjeldahl method

During the summer and autumn of 2006 moss samples were collected from 98 sampling sites (85 of which were analysed for N) evenly distributed all over the territory of Croatia. Moss sampling was repeated in 2010 when additional sampling sites were added (in total 121 sampling sites). The most dominant moss species in this study area were Hypnum cupressiforme, Pleurozium schreberi, Homalothecium sericeum, Hylocomium splendens and Brachythecium rutabulum. Kjeldahl method was used to determine the nitrogen content in the samples according to ISO 5663:1984 and EN 25663:1993. Descriptive statistics and distribution maps were prepared.
