To compare three biomonitoring techniques for assessing nitrogen (N) pollution in Germany, 326 lichen, 153 moss and 187 bark samples were collected from 16 sites of the national N deposition monitoring network. The analysed ranges of N content of all investigated biomonitors (0.32%-4.69%) and the detected δ(15)N values (-15.2‰-1.5‰), made it possible to reveal species specific spatial patterns of N concentrations in biota to indicate atmospheric N deposition in Germany. The comparison with measured and modelled N deposition data shows that particularly lichens are able to reflect the local N deposition originating from agriculture.
为了比较三种生物监测技术在评估德国氮（N）污染方面的效果，从国家 N 沉积监测网络的 16 个站点采集了 326 份地衣、153 份苔藓和 187 份树皮样本。所有受调查生物监测器（0.32％-4.69％）的 N 含量分析范围和检测到的 δ（15）N 值（-15.2‰-1.5‰），使得能够揭示生物群中特定物种的 N 浓度空间分布模式，以指示德国的大气 N 沉积。与实测和模拟的 N 沉积数据的比较表明，特别是地衣能够反映来自农业的局部 N 沉积。
