The authors demonstrate a possible relationship between the concentrations of metals (Cd, Cr, Cu, Fe, Ni, Pb, V, Zn) measured in mosses and the composition of Tardigrade species detected in the same samples. Cushions of Hypnum cupressiforme were collected at 18 sites distributed in the whole of Hungary to estimate the background air pollution, then analyzed by ICP-AES to determine the concentrations of heavy metals. Data reflect the expected correlation; elevated heavy metal contents decrease the number of water bear species and of specimens, and abundance of Tardigrada depends strongly on air pollution. Higher concentrations of cadmium and chromium seem to have particularly damaging and toxic influence on community structure. As the biologically relevant effects of pollution can only be evaluated by carrying out measurements on the organisms themselves, our method applied species of Bryophyte and of Tardigrade, as bioindicators were appeared to be an adequate method to show the effect of air pollution on abundance of water bears.
作者证明了在苔藓中测得的金属（镉、铬、铜、铁、镍、铅、钒、锌）浓度与在同一样本中检测到的缓步动物物种组成之间可能存在的关系。在匈牙利全境分布的18个地点采集了桧叶金发藓的垫层，以估计背景空气污染情况，然后通过电感耦合等离子体原子发射光谱法（ICP - AES）进行分析，以确定重金属浓度。数据反映了预期的相关性；重金属含量升高会减少水熊物种和标本的数量，并且缓步动物门的丰富度强烈依赖于空气污染。较高浓度的镉和铬似乎对群落结构具有特别的破坏和毒性影响。由于污染的生物学相关影响只能通过对生物体本身进行测量来评估，我们应用苔藓植物和缓步动物物种作为生物指示物的方法似乎是一种显示空气污染对水熊丰富度影响的适当方法。
