Currently there exist a variety of techniques and technologies associated with passive construction, energy-efficient smart homes, the use of renewable energy sources. The task of modern architects is the creative and innovative search for new functional and aesthetic architectural solutions that are technically and technologically conditioned to guarantee its users a healthy and secure life in a friendly environment.

Earthquake of Olesky area and surrounding areas within the Lviv region and in particular some features of earthquakes in V. Mosty (1875) and Komarno (2007) as well as influence on a given territory from Vrancea zone earthquakes (in particular, the earthquake in 1838) are analyzed. According to foreign reports about the influence of the method of hydraulic fracturing on seismicity the conclusion about possible changes of seismic regime of the area and increase the possible danger to water resources of Lviv region from shale gas extraction were made. 

The results of electro-magnetic diagnostics of the medium in the upper part of geological cut between river of Sivka and the northern border of quarry are presented. Time domain electromagnetic sounding has detected and quantitatively outlined a zone of anomalous conductivity associated with development of filtration-suffosion and karst processes in the gypsum-clay cap and in the ore body as a result of infiltration of river waters and atmospheric precipitations into water-bearing horizon, and their migration in the border zone at lower hypsometric dates.

Purpose. Designing both the apparatus and methodical means based on the classical methods of electroprospecting and their modification. Using this set for an elecromagnetic monitoring of environmentally problematic objects. The objects to be observed are ground dams, haloes of underground water pollution, mine fields, geotechnical objects. Methodology. High-speed technological set was created and had been studying in the environmentally problematic areas in pre-Carpathians (Yavoriv, Stebnyk, Kalush etc.).

The powerful oxidative action of ozone provides basis for development of novel or improved technologies which are widely used in ecology and industry. Special attention is paid to purification of waste gases, water, and soils.  The disinfection and cleaning of drinking and process water are considered in detail. Applications of ozone in chemical, pharmaceutical and perfume industries, cosmetics, cellulose, paper and sugar industries, flotation, microelectronics, and many others are also examined in the review.

In the review physical and chemical aspects and technological parameters of the rubbers production processes from industrial latex with application of ammonium halogenides, tetraalkylammonium salts, poly-(N,N-dimethyl-2-oxypropyleneammonium) chloride, poly-N,N-dimethyl-N,N-diallylammonium chloride, and his copolymer with SO2 are considered. A significant ecological effect of polymeric flocculants application is shown.
