Abstract

W publikacji tej opisano właściwości fizykochemiczne szlamów arsenowych pozostałych po flotacji rud arsenowych i porastające je rośliny. Miejscem badań jest Złoty Stok - kolebka światowej metalurgii arsenu (1709-1961). Stwierdzono, że w warstwie ryzosfery (O- 25 cm) jest bardzo mało N, Na, Fe i próchnicy, mało P, średnia zawartość Ca i K oraz bardzo dużo Mg. Ich odczyn jest zasadowy. Analiza roślinności wykazała, że przez ok. 40 lat na szlamach pojawiło się 67 gatunków roślin naczyniowych. Są to wyłącznie apofity, wśród których dominują hemikryptofity, rośliny światłolubne i neutralne w stosunku do kontynentalizmu klimatu oraz mezofity i higrofity, mezo- i eutrofy oraz acidofilne do bazyfilnych. Gatunkiem dominującym jest Calamagrostis epigejos (L.), rzadziej występuje Carlina vulgaris L., Centaurea phrygia L., C. scabiosa L., Daucus carota L. i Festuca rubra L.

Abstract

The environmental assessment of the surface water quality of the Western Bug River has been made using the system of classification quality of land surface water of Ukraine in accordance with the approved methodology, which allows comparing water quality of separate areas of water objects of different regions. The calculation of the environmental as-sessment of water quality has been carried according to three blocks: block of salt composition, block of trophic and sapro-bic (ecological and sanitary) indicators and block of indicators of content of specific toxic substances. The results are pre-sented in the form of a combined environmental assessment, based on the final conclusions of the three blocks and consists in calculating the integral ecological index. Comprehensive studies of changes in the water quality of the Western Bug Riv-er have been conducted within the territory of Ukraine for a long-term period. The water quality of the river on the final values of the integral indicators of the ecological condition corresponded mainly to 4nd category of the 3rd class – the wa-ter is “satisfactory” by condition and “little polluted” by degree of purity (except for points of observation that located within the Volyn region, where the water quality corresponded to 3rd category and the 2nd class. It is “good” by condition and “fairly clean” by the degree of purity). Visualization and part of the analysis are performed using GIS technologies in the software of the ArcGIS 10.3.
