Abstract—The territory of modern central Donbass was considered as an experimental site for the implementation of an ingredient biomonitoring program. Bryophytes were transplanted and exposed in the geolocalities directly influenced by coal mining and processing complexes, metallurgical and chemical industry, ruderal and residential ecotopes. For bryobionts with a wide amplitude of resistance to technogenic pollution (Amblystegium subtile (Hedw.) Schimp., Brachythecium campestre (Muell.Hal.) Bruch et al., Bryum argenteum Hedw., Bryum caespiticium Hedw., Bryum capillare Hedw., Ceratodon purpureus (Hedw.) Brid and Pylaisia polyantha (Hedw.) Schimp.), the following criteria of anthropotolerance were selected: (1) the ability to accumulate elements, (2) the ability to accumulate specific pollutants, (3) structural and functional reactions and manifestation of atypical morphogenesis (teratogenesis) of plant organisms and (4) shifts in the characteristics of the survival strategy of species under conditions of deep transformation of the Donbass landscape systems. Peculiarities in the accumulation of Na, Mg, Al, Si, P, S, Cl, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Br, Rb, Sr, Zr, Mo, Cd, Sb, I, Cs, Ba, La, Ce, Nd, Sm, Eu, Tb, Dy, Yb, Hf, Ta, W, Hg, Pb, Th, U in indicator plants used as seasonal phytotest monitors to assess the pollution of natural environment has been defined.

顿巴斯地理化学对比条件下苔藓虫形态发生异常

摘要——现代顿巴斯中部地区被认为是实施成分生物监测计划的实验地点。苔藓植物被移植并暴露在受煤矿和加工综合体、冶金和化学工业、农村和居民生态区直接影响的地理位置。对于对技术源污染具有广泛抗性的苔藓虫（Amblystegium subtile（Hedw.）Schimp。，campestre短臂古猿（Muell.Hal.）Bruch等人。，Caesapiticium Hedw。，Bryum capillare Hedw。，Ceratodon purpureus（Hedw.）Brid和Pylaisia polyantha（Hedw）Schimp.），选择了以下人类耐受性标准：（1）积累元素的能力；（2）积累特定污染物的能力，（3）植物生物的结构和功能反应以及非典型形态发生（致畸）的表现，以及（4）在顿巴斯景观系统深度转型的条件下物种生存策略特征的变化。定义了Na、Mg、Al、Si、P、S、Cl、K、Ca、Sc、Ti、V、Cr、Mn、Fe、Co、Ni、Cu、Zn、As、Se、Br、Rb、Sr、Zr、Mo、Cd、Sb、I、Cs、Ba、La、Ce、Nd、Sm、Eu、Tb、Dy、Yb、Hf、Ta、W、Hg、Pb、Th、U在用作季节性植物试验监测器评估自然环境污染的指示植物中的积累特征。在彻底违反植物生命支持系统中的地球化学循环的情况下，点定位的特定黄化和坏死、低生和超生和变形，以及营养器官的筋膜化、增殖、反乌托邦、寡聚化，珠被中单个细胞群发育的特异性，并记录了苔藓虫叶器的构象组织。在现场诊断中对技术成因应激水平进行表达分析时，所揭示的异常被用作植物指示特征。在评估环境的地球化学对比时，计算了生物基质中元素的生物吸收系数和技术成因浓度。定义了不同生态区苔藓虫对单个元素或其结合群的累积能力的差异。植物结构和元素组成的相关形态发生异质性是符合V.I.Vernadsky关于生物的集中、信息和环境形成功能的观点的一个个案。
