“…It is interesting that in different parts of the globe, in various types of ecosystems, the phosphate content in water has diverse effects on phytoplankton parameters. Thus, in the coastal waters of India, phosphorus has less of an effect on phytoplankton diversity compared to nitrate content in water [27]. Similar results were obtained in the coastal waters of China, where the number and species diversity of phytoplankton depend on the phosphate content in the water much less, compared to the temperature factor and the nitrate content [28].…”

The main causes of surface water pollution with phosphate ions are various human activities. Monitoring the content of phosphorus compounds in surface waters is important for the management of water bodies. Phosphorus is an essential element for the life of flora and fauna, but in excessive amounts it can have a harmful effect on the environment. The inflow of phosphorus compounds into the Styr River (Western Ukraine) occurs as a result of the discharge of cooling water from the Rivne NPP’s cooling water system. This article has three purposes: (1) The inflow of phosphorus compounds to the Styr River occurs with the discharge of cooling water using 1-hydroxyethylidene-1,1-diphosphonic acid (HEDP); (2) phosphorus compounds (phosphate ions, HEDP, and total phosphorus in surface waters of the Styr River) are monitored and analyzed, and the analysis of the quality of river water is carried out in accordance with environmental standards for the content of phosphorus compounds in the zone of influence of the Rivne NPP; (3) in terms of phosphorus content, the quality of the water of the Styr River, after the discharge of the Rivne NPP’s cooling water, is characterized as “satisfactory” and belongs to Class III. A seasonal trend of changes in the content of phosphate ions and total phosphorus was found, and the concentration of HEDP in the water of the Styr River depends on the technological dosage mode during the corrective treatment of the Rivne NPP.

“…Landscape coherence and homogeneity: The degree of landscape homogeneity and coherence will be assessed using the Shannon diversity index. This index, based on the principle of entropy and more common in the field of ecology of species [40][41][42][43], was adapted for its application in the territorial analysis. Our adaptation to landscape analysis of the Shannon diversity index (SDI) provides information about area composition through the number of land cover types present in the Corine Land Cover [29].…”

The evaluation of anthropogenic impacts on the landscape is an issue that has traditionally been carried out from a descriptive or at least somewhat qualitative perspective. However, in recent years, the technological improvements provided by geographic information systems (GIS) and spatial statistics have led to more objective methodological frameworks for analysis based on quantitative approaches. This study proposes an innovative methodological framework for the evaluation of landscape impacts of the usual anthropization phenomena, using a retrospective spatiotemporal analysis based on geostatistical indicators. Various territorial indices have been used to assess the spatiotemporal evolution of fragmentation of the built-up urban fabric, the construction of roads or linear communication works and the changes in land use. These phenomena have been statistically correlated with objective indicators of the landscape’s intrinsic value. The analysis of said spatial statistical correlation has been applied to three different but neighboring environments in the region of Murcia, located in the southeast of Mediterranean Spain, providing interesting results on the objective impact of each of these phenomena on the landscape and depending on the boundary conditions.
