Opis:
The problems of coherence and comparability exceed the classical notion of analysis of survey errors, because they do not concern single surveys or variables but the question of how results of two or more surveys can be used together and how relevant data can effectively be compared to obtain a better picture of social and economic phenomena over various aspects, e.g. space or time. This paper discusses characteristics of the main concepts of coherence and comparability as well as a description of differences and similarities between these two notions. Types of coherence and various aspects of perception of these notions in business statistics are analysed. Main sources of lack of coherence and comparability, factors affecting them (e.g. methodology, time, region, etc.) and methods of their measurement in context of information obtained from businesses will be also presented.

Opis:
The article describes modern anthropogenic load on the surface water of the Southern Bug River Basin in a changing climate. The main water users-pollutants of the Southern Bug River Basin in Vinnytska and Mykolaivska regions were identified. The water quality of the surface water of the Southern Bug River in time and space (along the river stream) was analyzed. The water quality of the Southern Bug River was assessed by complex indices for different water users. In order to assess water quality, it is recommended to use complex indices that take into account the effect of the total action of pollutants. The self-purification potential and capability of restoration in space (along the river stream) of the aquatic ecosystem of the Southern Bug River was established for 2019. The results of the study allow us to state that the use of surface water of the Southern Bug River Basin for drinking, fishery, cultural and recreational needs is related to certain environmental risks. It is recommended to carry out the environmental protection measures aimed at adjusting the priorities of economic activity, reduction of wastewater discharge and increase in the water content of the river by regulating the operation of energy complexes.
