Розглядаються основні чинники, які дадуть змогузнизити чисельність синьо-зелених водоростей –головних збудників процесу евтрофікації. Встанов-лено інтенсивність процесу евтрофікації води врічці Ворскла. Визначено оптимальні умови длярозвитку ціанобактерій. Наведено результатидосліджень із вивчення впливу різних хімічних ре-човин на розмноження мікроорганізмів. Охаракте-ризовано евтрофікаційні процеси річки Ворскла, зякої проводився збір агроекологічної інформації;вказано кількісний склад синьо-зелених водорос-тей. Розроблено заходи боротьби з процесамиевтрофікації води в річці Ворскла. The main factors that help to reduce the number of bluegreenalgae are considered. The intensity of the processof eutrophication of water in the river Vorskla has beenestablished. The optimal conditions for cyanobacteriahave been determined. The results of studies on examinationof the impact of various chemicals on the reproductionof microorganisms have been presented. Eutrophicationprocesses of the Vorskla River from whichagroecological information was collected have been characterised.The number of blue-green algae has been specified.The measures on control of eutrophication processof water in the river Vorskla have been developed.

Abstract A baseline for biological and chemical water quality conditions was established for a section of the Welland River which daily receives large quantities of nitrogenous and carbonaceous inorganic compounds from Cyanamid of Canada Limited. Specific conductivity transects across the river at various locations indicated that the effluents discharged clung to the north shore of the River. In addition, simultaneous continuous conductivity measurements from above and below the plant were made during five one-week long periods and the results temperature corrected. At the upstream site conductivity never exceeded 400 limhos/cm while below the plant it averaged 950 umhos/cm with sporadic peaks exceeding 1 0,000 umhos/cm. Epiphytic diatoms scraped from typha stalks growing in the water at sites above the plant were dominated by Nitzschia dissipata, while the pollution tolerant diatom, Nitzschia palea, dominated at the majority of the downstream sites. In addition, blue green algae replaced filamentous green algae below the plant. Higher aquatic plants reflected a very distinctive zonation pattern. No higher aquatics were found growing in the water in the impact zones immediately below the effluent outfalls. The first macrophytes to appear downstream of these sites were cattails, while further downstream the arrowheads (sagittaria) and later the submersed macrophytes, such as Elodea and Myriophyllum appeared. No resident fish population occurred along the north shore downstream of the plant. Shiners and other small transient fish species which were observed entering the effluent plume near Thompson's Creek during periods of shock loading went "belly-up" within one minute indicating the extreme toxicity of these waters.
