Abstract
ICP-MS method was used to study the elemental composition of benthic Baikal algae and algae of the genus Spirogyra, excessive growth of which was registered within the last decade in the littoral zone of Lake Baikal. The distribution of chemical elements in Spirogyra algae (Spirogyra “morphotype 1”) dominating stony littoral locations is as follows: Na ~ K ~ Ca ~ S ~ Ba > Mg ≥ P > Mn ≥ Cl) and Spirogyra spp. from tributary streams, shallow coves and bays with soft bottom grounds—Na > K ≥ Ca ~ S ~ P ~ Ba ≥ Mg, Cl > Mn. Spirogyra algae were characterized by higher content of Li, Na, Mn, Ba and atypical ratio of element concentrations: Na > P, Na ≥ K and Ca, Mn > Fe, Ba ~ Ca and S, Ba > Sr compared to benthic Baikal algae. Maximum total content (∑С) of all detectable elements, ∑С Na Mg P S Cl Ca Li Al Si Mn Zn Ba, ∑С Na Cl P Mn are typical Spirogyra “morphotype 1,” dominant on littoral areas located in the vicinity to sources of heaviest wastewater emissions. Overgrowths of other Spirogyra species, capable of accumulating larger amounts of Li, Na, Cl, Br than Spirogyra “morphotype 1” are also confined to such pollution sources.
摘要 采用ICP-MS方法研究了贝加尔湖底栖藻类和螺藻属（Spirogyra）藻类的元素组成。在石质沿岸地区占主导地位的螺藻（螺藻 "形态 1"）中，化学元素的分布情况如下：Na ~ K ~ Ca ~ S ~ Ba > Mg ≥ P > Mn ≥ Cl）和来自支流、浅湾和软底海湾的螺藻属--Na > K ≥ Ca ~ S ~ P ~ Ba ≥ Mg, Cl > Mn。螺旋藻的特点是锂、Na、Mn、Ba 含量较高，元素浓度比例不典型：与贝加尔湖底栖藻类相比，螺旋藻的特点是锂元素、锰元素、钴元素含量较高，且元素浓度比例不典型：Na > P、Na ≥ K 和 Ca、Mn > Fe、Ba ~ Ca 和 S、Ba > Sr。所有可检测元素的最大总含量（∑С）、∑С Na Mg P S Cl Ca Li Al Si Mn Zn Ba、∑С Na Cl P Mn 是典型的螺旋藻 "形态 1 型"，主要分布在废水排放最严重的沿岸地区。与螺藻 "形态 1 型 "相比，能积累更多 Li、Na、Cl、Br 的其他螺藻物种的过度生长也局限于此类污染源。
期刊介绍：
Water Resources is a journal that publishes articles on the assessment of water resources, integrated water resource use, water quality, and environmental protection. The journal covers many areas of research, including prediction of variations in continental water resources and regime; hydrophysical, hydrodynamic, hydrochemical and hydrobiological processes, environmental aspects of water quality and protection; economic, social, and legal aspects of water-resource development; and experimental methods of studies.
