    Opis:
    The purpose of the research was to raise the level of environmental safety in the coal mining regions by using combustion metamorphic rocks of the spoil banks, which were reinforced with the modified wastes of the polymer production, namely carbonous binders, as a man-made raw material for the base courses of roads. The environmentally friendly technology for the construction of the base course of roads from layers of combustion metamorphic rock mixtures (CMRM) with different largest granule size of crushed stone was developed. The bulk density and compressive strength in a cylinder on a hydraulic press were used as the criteria for determining the rational granulometric composition. The practicability of reinforcing combustion metamorphic rocks with coal tar, which is a modified waste of the polystyrene production, i.e polystyrene dust, was shown. The technology of preparation of the tar and polystyrene binder (TPB) was developed. The optimal concentration of polystyrene dust in the organic binder of the coke production and the time of their combination (as the optimal areas of admissible values of variation factors X1, X2, X3) were determined using the method of mathematical planning of the three-factor experiment (5 optimization parameters). The coefficients of the regression equations were calculated using the least squares method. Regression equations are a second-degree polynomial. The three-dimensional diagrams “parameters of system optimization – variance factors” were calculated and drawn. In accordance with the obtained regression equations, the response surface was designed in a three-dimensional space. The areas of admissible values of optimal variance factors correspond to the limit values of the response functions.

    Opis:
    The rare earth elements (REE) are vital to innovation technologies and society and are important for the industry, especially for high-tech solutions. In the modern world, anumerous applications have been developed using rare earth elements (REE), implying human exposures and raising unclear questions as to REE-associated health effects. Protecting the environment and public health from disadvantageous actions of rare earth elements mining and processing as emerging pollutants is urgently desired to achieve sustainable development. All activities in mining processes like extraction, separation and after recycling of REE elements could create rick to human health and environment. In the paper the role of management in safety aspects during mining and processing of rare earth elements has been highlighted. In the paper, the potential dangerous and damaging effects on the environment and human health have been identified - the potential risk in the processing as well as the possibilities of preventing the occurrence of hazards have been analyzed.

    Opis:
    The environment determines the existence of a man who nowadays is considered to be the main, sometimes the only protagonist of transformations. Man tied its existence with nature, depends upon it, but at the same time conditioned its existence from his good or ill will. He possess the tools and knowledge about the possibilities of its transformation and even annihilation. That is why he occupies a unique position in the universe. Efforts to protect the living environment must be multidirectional and coordinated. It is possible that in future modern biotechnology will be the solution for balanced development, which provides the possibility to exercise control over the economy and scientific research. Decision-making in this area involves the responsibility of international institutions, governments and citizens. Ergo, it is important that the development and use of modern technology, knowledge and skills, are performed in conditions which ensure maximum safety and without any rebounds to humans and their living environment.
