Sztucznie zanieczyszczone za pomocą roztworów azotanów: Cu, Zn, Ni i Pb próbki gleby ogrodowej i uniwersalnej oraz próbkę gleby pobraną z terenu skażonego przemysłowo poddano ekstrakcji za pomocą 10-proc. roztworu kwasu cytrynowego, kwasu winowego, wersenianu disodu lub wersenianu tetrasodu, mieszając z prędkością 500 rpm przez 24 h. Zawartość metali ciężkich w ekstrakcie oznaczono metodą spektrometrii płomieniowej FAAS. Wersenian disodu wykazywał dużą skuteczność wymywania metali ze wszystkich badanych gleb. Najbardziej podatnymi na ługowanie pierwiastkami były miedź (Cu) i cynk (Zn), a najsłabiej ołów (Pb).

Garden and universal soil samples were mixed with solns. of Cu, Zn, Ni and Pb nitrate, then dried and conditioned. Artificially contaminated soils and a soil sample taken from an industrially polluted area were extd. with 10% solns. of citric acid, tartaric acid, disodium edetate or tetrasodium edetate, while mixing at 500 rpm for 24 h. The content of heavy metals in the extract was detd. by FAAS. Disodium edetate was highly effective for leaching for all the soils studied. Regardless of the leaching soln. used, the most susceptible elements to leaching were Cu and Zn, while Pb was the weakest.

Purpose: The research objective of this paper was to define the lines of the environmental technologies development in the context of the transformation of the economy towards green growth. The discussion focuses on the challenges accompanying the transformation processes and the implementation of sustainable technological changes. The research results allowed identifying the prospective lines of technological development regarding the transformation towards green growth as well as the future research areas. Design/methodology/approach: The study was based on the analysis of the development trends strictly connected with environmental technologies. The adopted methodology involved a comprehensive literature review and quantitative research using the CAWI technique combined with complementary qualitative research using an expert panel. Findings: The analyses allowed distinguishing the most important trends and placing them within the process of the Silesia Province green transformation. The dominating importance was attributed to energy generation, storage and decarbonization (CCS and CCU) technologies. Research limitations/implications: The paper highlights the green transformation issues and the technological changes within the transition process while searching for a model approach enabling to delineate the development determining factors, especially environmental technologies. Practical implications: The study results can be used to formulate development scenarios and conduct analyses that involve these green economy components which determine the development of chosen technological areas. Originality/value: In the coming years, green economy will constitute a significant area of regional and international development incorporating resource management, RES, energy and material efficiency, clean technologies, CSR, biodiversity protection or the models of sustainable consumption and production. However, there is no research on how green economy is to be implemented in areas undergoing transformation, particularly, which technologies and factors should be considered. The identification of the challenges concerning the transition towards green economy and environmental technologies may prove critical for the Silesia Province, a region heavily affected by transformation processes, to formulate its 2030 Green Silesia Strategy and the development of its regional specialization.

It is widely known and accepted that the global climate is changing with unprecedented speed. Climate models project increasing temperatures and changes in precipitation regimes which will alter the frequency, magnitude, and geographic distribution of climate-related hazards including flood, drought and heat waves. In the mining industry, climate change impacts are an area of research around the world, mostly in relation to the mining industry in Australia and Canada, where mining policies and mitigation actions based on the results of this research were adopted and applied. In Poland, there is still a lack of research on how climate change, and especially extreme weather events, impacts mining activity. This impact may be of particular importance in Poland, where the mining industry is in the process of intensive transition. The paper presents an overview of hazardous events in mining in Poland that were related to extreme weather phenomena. The needs and recommended actions in the scope of mitigating the impact of future climate change on mining in all stages of its functioning were also indicated. The presented analyses and conclusions are the results of the first activities in the TEXMIN project: The impact of extreme weather events on mining activities, identifying the most important factors resulting from climate change impact on mining.
