Opis:
The main purpose of the article analyses the stability of sustainable development of the enterprise and determines the approaches to the interpretation of this concept. In modern conditions, the relevance of this article is that the concept of sustainable development is becoming increasingly popular because it can ensure economic growth and increase the competitiveness of the enterprise. Therefore, more and more companies are reviewing their strategies in favour of the concept of sustainable development. The article analyses the content of the investment-innovation model of enterprise devel-opment as an integral part of ensuring the sustainability of the enterprise. It also identi-fies the factors hindering the implementation of this strategy and the mechanisms for attracting investment in innovation. Additionally, it examines the statistical data on the implementation of the concept of sustainable development both among Ukrainian and foreign senterprises. The methodology of this study consists of general and special re-search methods: including analysis, synthesis, and systematization.

Opis:
The research analyzed seasonal changes of the oxygen regime and related indicators on the example of water objects of the Ukrainian Polesie Region. The region shows different directions of economic use. Zebrafish (Danio rerio Hamilton–Buchanan) and the Prussian carp (Carassius auratus gibelio Bloch) were used as test objects to investigate survival responses. Dissolved oxygen (DO) concentration in water, pH values and temperatures were determined by standard methods. Based on research results, the main problems were determined pertaining to the oxygen regime of investigated waters, i.e. the increase in temperature and toxicity of the aquatic environment in the summer. A rather dangerous decrease in DO concentration, almost up to the levels of maximum allowable concentration (MAC) (4.10 mg∙dm–3 in group E1 and 6.07 mg∙dm–3 in group E2), was observed in August and it was typical for the reservoirs with a slow water movement. Flowing river waters (group E3) were eliminated due to their better aeration compared to other groups. The correlation analysis based on the presented data revealed a high and average degree of probable correlation between the DO concentration and water temperature, as well as an average degree of correlation with general toxicity determined on sensitive species of D. rerio, and in group E1 on the persistent species C. auratus gibelio as well. The interrelations and equations of the rectilinear regression can be used to predict the oxygen regime of the waters investigated and other surface waters having similar problems.
