Assessing the Environmental Condition of Minor Rivers in Urban Areas

Kuznetsov V. S., Petrov D.S.

Journal of Ecological Engineering

2017

Vol. 18, nr 6

110--114

This article is devoted to the study of water and sediment pollution in the channel of the Neva delta. Spectrophotometry was used to determine the concentration of pollutants in water. In the chemical analysis of the precipitate, atomic absorption spectroscopy and infrared spectroscopy were used. Analysis of the hydrochemical composition and sediment of the Smolenka River showed high concentrations of heavy metals and petroleum products. At the same time, the hydrochemical composition of the Smolenka River is highly unstable, but the concentration of oil products and lead in the sediments indicates the presence of local pollution sources. Based on our findings, we are guided by the restoration of the aquatic environment.

Assesment of minor rivers flood-plain and stream-way complex condition (case study of the Berezhnytsya River, Dniestr basin)

The methodological and practical issues in respect of assessment of the flood-plain and stream-way complex of the Berezhnytsya river are presented in the article. Researched river is one of the Ukrainian Carpathians minor rivers and constituted the right-bank tributary of the Dniester river. The presented study typify the stream-way segments. Furthermore were shown identification of the reasons of decreasing the qualitative characteristics of the Berezhnytsya flood-plain and stream-way complex. The set of works to stop processes that are destructive for the river and its ecosystem should be made.
