Assessing the Environmental Condition of Minor Rivers in Urban Areas

Abstract

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.

Cadastral Land Value Modelling Based on Zoning by Prestige: A Case Study of a Resort Town

“…The article [53] explains the choice of several criteria for assessing the prestige of districts in resort towns, which include: proximity to the sea coast with public beaches; availability of entertainment venues; environmental quality, including the sea coast and the sea itself [54,55]; microclimatic conditions [56,57]; the opportunity to install utility lines [58]; population density; hotel ratings. These criteria will make it possible, first, to state if there any prerequisites for the emergence of prestigious districts in resort towns; second, to state where their boundaries are; third, to confirm or refute the hypothesis that pricing processes differ depending on how prestigious areas are; fourth, to find the cadastral value of a land plot taking into account the prestige of the area where it is located.…”

Modeling the Size of Protection Zones of Cultural Heritage Sites Based on Factors of the Historical and Cultural Assessment of Lands

“…The need to strengthen the protection and sustainability of cultural and natural world heritage is also laid down in the Sustainable Development Goals (SDGs) adopted by the United Nations (UN) Member States in 2015 [1]. At present, in the context of active human economic activity in urbanized areas as well as the impact of negative environmental and urban planning factors, this issue is becoming more and more relevant [2,3]. In their study, G. Chen, J. Shi, Y. Xia, and K. Furuya [4] revealed the influence of urbanization on the attractiveness of historical landscapes for tourism and on the sustainable development of territories of historical landscaping.…”

“…These restrictions are considered in th of land use regulation, which is associated both with creating conditions for su development of territories, ensuring the comfort of living of the population and in its wellbeing, as well as preserving the environment, reducing the negative impa environment and humans, and preserving cultural heritage sites. Effective and use of territories makes it possible to maintain land and resource potential and t sustainable development, which the modern world is seeking to achieve [18,23,2 According to the Federal Law dated 25,06,2002 No. 73-FZ "On Cultural Herit (Historical and Cultural Monuments) of the Peoples of the Russian Federation" t the safety of a real estate object's value from the point of view of architecture culture, or science, the boundaries of the protection zones are established withi torical and landscape environment.…”

Bottom Sediments in a River under Acid and Alkaline Wastewater Discharge

“…In Russia, approximately half of the total streamflow volume accounts for small rivers [Kuznetsov & Petrov 2017, Nevskaya et al 2019]. Due to minor runoff volumes in small rivers, the self-remediation process is slower, and the longterm anthropogenic impact leads to the degradation of water ecosystems [Kremcheyev et al 2020, Puzanov et al 2015].…”
