Abstract
The harmful effect of wastewater factor on stenobiont organisms of the Gammaridae family is experimentally determined. Based on the defined environmental characteristics of aquatic organisms in the estuarine complex of the Southern Bug river (Mykolaiv region, Ukraine), the calculated ecological system safety index, which can vary in the range 0˂ESI˂1, takes the value of 0.18. This suggests a crisis ecological situation in the ecological system of the river and is confirmed by the graphic and analytical material, presented in the paper. Double integration (using living organisms as an integrated status indicator of the river, the lower reaches of which fully reflects the level of balance of the “man-nature” system in its basin) allows speaking about considering the principle of comprehensiveness in the evaluation results. The causal relationships between the economic complex of human and the natural systems, which primarily determine the low current value of the proposed index are analyzed. The experimental work with further ESI calculations proves the failure of regulatory evaluation of the concept of human impact on the environment to ensure the objectivity of evaluation. The result of the research is the practical implementation of new theoretical developments in the field of safety assessment of ecological systems. The resulting index value correlates well with both qualitative and quantitative characteristics of the studied water ecosystem. The theoretical work on the algorithm of ensuring (management) the ecological safety of natural and socio-natural systems is also extended. The developed technique can also be used to assess the social, economic development components and for a generalized indicator of sustainable development.
Highlights
The subject of scientific works in recent decades is increasingly directed at finding optimal conditions of interaction between the economic complex of human and ecological systems
Taking into account that almost the whole region is located in the basin of the Southern Bug, a study was conducted in the estuarine part of it, which is considered as the most representative area of water ecosystem in relation to human impacts
Evaluation of the ecological safety index (ESI) complex of ecosystems of most representative in terms of nature management quality the region, is proposed to make by analyzing the identified upstream throughout the basin (total anthropogenic impact hydrocoles in the river estuarine systems, which are on the ecological system), sampling point was city beach integral indicators of the basin(s) condition in the whole re
Summary
The subject of scientific works in recent decades is increasingly directed at finding optimal conditions of interaction between the economic complex of human and ecological systems This gradual and sure development of “co-evolutionary” theme occurs because in this era of computer’s mobile information technology it is much easier to understand the main vector of negative human impact on nature, see and feel the effects of it at every corner of the biosphere. The development and the use of new methods for assessing the environmental safety of natural systems, which are based on the ecosystem approach and the basic principles of sustainable development are of particular importance today. In other words – the methods of bioindication and biological testing that more objectively describe the safety of the ecological system
