Abstract. Ecological danger from uncontrolled accumulation of arboreal wastes in the region of Pokuttia–Bukovyna Carpathians has been estimated. The optimum terms of wood wastes drying in an immobile layer have been studied. The optimum conditions for getting fuel brequettes from wood wastes by the pressing method havw been set. Lignin-containing industrial wastes have been used as a relating component. The principal technological scheme has been offered for fuel granules production from wood wastes by the pressing method.

Key words: wood wastes, pressing, fuel brequettes, utilization, the Pokuttia–Bukovyna Carpathians.

Abstract. The risk to the health of the population from carbon oxide and hydrocarbon waste influence of carbon producing enterprises is estimated in this work. After analyzing the ecological safety of emissions of the carbon producing enterprises it was determined that their activity belongs to the average level of risk and ability to get respiratory organs diseases, sight, cardiovascular and central nervous system diseases for old people, pregnant women and children.

Key words: gaseous waste, carbon oxide, hydrocarbons, pollution, atmosphere, ecological safety, inhabitants, health risk.

Abstract. The paper evaluates the potential impact of internal biogenic pollutants (phosphorus) on the trophic state of the deep, stratified Lake Swiete in Obra, Poland (area 23.3 ha, depth 15.3 m). The amount of phosphorus in interstitial water was analyzed on the basis of spatial studies of 10 cm of surface sediments of bottom sediments. It has been shown that the release of loading accumulated in the water can worsen the trophic state of the lake.

Key words: bottom sediments, eutrophication, internal loading, interstitial water, phosphorus

Abstract. A method of eco-energy analysis of household refrigerating appliances based on the life cycle of GHG emission assessment is presented. A new eco-energy efficiency indicator is proposed. Calculation of the eco-energy efficiency indicator and traditional energy efficiency index for three household refrigerators has been performed. The qualitative difference in the results of comparison of these indicators for the analyzed refrigerators is shown.

Key words: GHG emission, energy-saving, life cycle analysis, household refrigerating appliance.
