Purpose. Environmental assessment of the quality of surface water of small and medium rivers of the Poltava region, in particular: medium rivers – Psel, Vorskla, Merla and five small rivers –Govtva, Grun, Kolomak, Poluzorie, Tashan. Methods. Field, atomic absorption spectrophotometry, cluster analysis. Results. In accordance with the quality standard for surface water of cultural and household purposes, all indicators for medium-sized rivers are within the normal range. There was an excess of zinc in the waters of small rivers - Grun, Tashyas and Poluzorie. The low content of soluble oxygen does not meet the norm. When comparing values with the norm of quality of water for reservoirs of fishery management, excess BOD-5 for the Vorskla and Psel rivers is defined; the content of ammonia and nitrites significantly exceeded the normative value for the river Vorskla, Psel, Merla. The excess of surfactants for medium rivers is determined. The river Vorskla is mostly polluted with cupper; the Psel river – with zinc and iron, in water from the Gotvva, Tashan, Poluzorie and Grun rivers we have identified exceeding BOD-5. Regarding the water-soluble nitrogen compounds, only the nitrogen content corresponds to the normative value. The greatest pollution with ammonia is observed for the Govtva and Kolomak rivers. Excess of MAC on the content of nitrites was identified for the Kolomak river. As a result of the cluster analysis of the river, the degree and nature of pollution of surface water are grouped into three main groups: the first is the Kolomak river, the second one is the Merla, Psel, Grun, Vorskla rivers, the third one is the Tashan, Poluzorie and Govtva rivers. In the future, the results can serve as a tool for regulation, monitoring and solution of pollution problems. Conclusions. Small rivers of Poltava region are under considerable anthro-pogenic impact, their ecological status is estimated as ecological regression. Therefore, priority attention should be paid to improving the ecological status of small rivers in the Poltava region and implementation of the pro-posed nature conservation measures.

Purpose. Space-time assessment of potential atmospheric meteorological Poltava region. Methods. according to V. Baranovsky, cartography. Results. Based on the analysis of spatial and temporal differences meteorological parameters in 2014 calculated meteorological potential for all regions of the Poltava region in terms of months. Determined that the lowest self-cleaning capacity of the atmosphere observed during the summer season in the southern region. This process determines the prevailing accumulation of harmful substances in the air. The highest self-cleaning ability of the atmosphere and the resulting domination processes of dispersion of pollution, mainly observed in winter in the northern and central regions. Cartographic work contained in Article lets you make spatial distribution of meteorological evaluation capacity throughout the year and adjust accordingly, emissions of air pollutants. Conclusions. Appropriate to recommend the construction of industrial plants and factories in the north, where their activities will cause less damage to the environment. Do not place the company in Velykobahachanskoho, Mirgorodskomu and Zinkivskomu areas as natural environment of these areas are the most favorable for recreation and health and medical institutions.
