This paper considers the element distribution between species in the lysimetric waters and lakes of the Valdai National Park in different seasons. Seasonal studies of natural waters and element speciation in them in 2019 using membrane filtration and ion-exchange separation showed the differences in the seasonal distribution of species depending on geochemical factors. The seasonal temperature factor causes a change of metal speciation from suspended (after meltwaters) through soluble mainly organic (summer) to inorganic/organic low-molecular (autumn) forms. The humus content in the water objects affects the transformation of colloid systems.

瓦尔代隆起天然水域元素形态地球化学特征（2019 年 3 月至 11 月）

本文考虑了不同季节瓦尔代国家公园溶渗水域和湖泊中物种之间的元素分布。2019 年使用膜过滤和离子交换分离对天然水域及其元素形态的季节性研究表明，物种的季节性分布因地球化学因素而异。季节性温度因素导致金属形态从悬浮（融水之后）通过主要有机（夏季）溶解到无机/有机低分子（秋季）形态发生变化。水体中的腐殖质含量影响胶体系统的转化。
