Abstract—

The paper presents the first ever data on the contents of 28 elements in aquatic plants of the duckweed family (Lemnaceae) in the territory of 65 population centers of the Russian Federation. Data are presented on the elemental composition of duckweed in the urbanized regions of Russia and on the spatial distribution of the studied elements and their calculated concentration coefficients relative to the estimated mean values in the macrophytes. The elemental composition of duckweed is shown to provide significant information about the current ecological and geochemical situation in the study area and can serve as an unbiased indicator of the impact of anthropogenic and natural factors on the environment.

俄罗斯联邦城市化地区浮萍科的元素组成

摘要-

该论文首次提供了俄罗斯联邦 65 个人口中心境内浮萍科（浮萍科）水生植物 28 种元素含量的数据。提供了有关俄罗斯城市化地区浮萍的元素组成、所研究元素的空间分布及其相对于大型植物中估计平均值的计算浓度系数的数据。浮萍的元素组成可以提供有关研究区域当前生态和地球化学状况的重要信息，并且可以作为人为和自然因素对环境影响的公正指标。
