Вивчено хімічний склад барди цукрового очерету (Тукуман, Аргентина) та встановлено високу концентрацію органічних сполук. Серед фенольних сполук виявлено переважно флавоноїди, антоціани, похідні резорцину та ферулової кислоти. Описано ізотерми адсорбції фенольних сполук та загальних органічних сполук на чотирьох комерційних активованих вугіллях з різними фізико-хімічними властивостями за двох температур. Встановлено, що форма ізотерми залежить від типу вуглецю, а адсорбційна здатність посилюється із збільшенням температури.

In Ukraine, there is still a great number of unused, unidentified and substandard pesticide preparations (PPs) and other toxic substances which have an extremely dangerous impact on humans and other living ecosystems and the environment. Besides, more than 75 thousand tons of pesticides are imported and produced annually in Ukraine, but some of them are not used during the period of their suitability.

The article analyzes the environmental risks of existing landfills in Ukraine (on the example of Hrybovytske landfill). The possible treatment technologies of the accumulated infiltrates were analysed and the successful application of infiltrates biological treatment technology in aerobic lagoons was confirmed.

In recent years there has been an increasing interest in the possibility of the use of natural aluminosilicates in agriculture and environmental protection. Zeolites are a large group of (cluster silicates) aluminosilicate minerals with different chemical composition. Due to their unique physical and chemical properties (high sorption capacity and ion-exchange, ion-exchange selectivity and structural thermal stability), they can be used for example in the production of mineral fertilizers. Zeolites can also be used as a medium of the active substances i.e.

The level of pollutant in river and reservoirs water in Ukraine is rather high. The assessment of the modern state of water resources in the different regions had been done. In generally it was determined that water infrastructure in Ukraine needs reconstruction. New State Program of Water Management Conception and new Law about water management up to 2020 had been approved. Nine basins committees were organized. Committees are composed of representatives of science, practical specialists and the public.

This review covers the main agents used for in situ and ex situ chemical oxidation of organic contaminants particularly oil products, in soil and water environments. Among them there are hydrogen peroxide, permanganate salts, ozone and sodium persulfate. The fields of application, as well as benefits and disadvantages of the mentioned agents use were described.
