Moss samples from four dominant species (Hypnum cupressiforme, Pleurozium schreberi, Homalothecium sericeum and Brachythecium rutabulum) were collected during the summer and autumn of 2010 from 121 sampling sites evenly distributed over the territory of Croatia. Samples were totally digested by using microwave digestion system, whilst mercury was analysed by using cold vapour atomic absorption spectrometry (CV-AAS). Descriptive statistics were done from analyses of mercury in all moss samples. The content of mercury ranged from 0.010 to 0.145 mg kg(-1) with a median value of 0.043 mg kg(-1). Hg distribution map shows the sites of the country with higher levels of this element. High contents of Hg were found in moss samples collected from the regions of Podravina and Istria as a result of anthropogenic pollution. Comparison of median values and ranges with those found in moss samples in 2006 shows slight reduction of mercury air pollution. When compared to the results obtained from recent studies conducted in Slovenia, Macedonia and especially in Norway-which serves as a reference considering the fact that it is a pristine area-mercury air pollution in Croatia is insignificant.
2010年夏秋两季，从克罗地亚境内均匀分布的121个采样点采集了四种优势苔藓（桧叶金发藓、高山金发藓、绢藓和曲尾藓）的样本。样本采用微波消解系统进行完全消解，汞则采用冷蒸气原子吸收光谱法（CV-AAS）进行分析。对所有苔藓样本中的汞分析进行了描述性统计。汞含量范围为0.010至0.145毫克/千克，中位数为0.043毫克/千克。汞分布图显示了该国该元素含量较高的地点。由于人为污染，在从波德拉维纳和伊斯特拉地区采集的苔藓样本中发现了高含量的汞。将中位数和范围与2006年苔藓样本中的结果进行比较，表明汞空气污染略有减少。与斯洛文尼亚、马其顿特别是挪威近期研究结果相比（考虑到挪威是一个原始地区，可作为参考），克罗地亚的汞空气污染微不足道。
