Environmental and chemical characteristics of the Zeya-Bureya plain small river Filinovka

Abstract

Abstract The article discusses the results of hydrochemical study of water of the small Filinovka River, the left-bank tributary of the Amur River, flowing along the south of the Zeya-Bureya Plain. Water is characterized by high oxygen content. The content of nitrogen and phosphorus compounds in water undergoes seasonal dynamics. The water of the small Filinovka River is characterized by a high content of iron and manganese, which are caused by the natural factor. The content of zinc and copper in water is higher than the fisheries standard. Macrophytes Najas marina and Ceratophyllum oryzetorum and feathers of birds Grus monacha and Grus vipio contain a high concentration of lead and cadmium. The results of studying the hydrochemical parameters of the water ecosystem of a small river flowing along the south of the Zeya-Bureya plain are the basis for studying the agricultural load on small rivers.
