Leaching of heavy metals (Zn, Pb, Cu, Ni and Cr) from hazardous waste originating from steel works (slag) has been investigated. Contaminant leaching behavior from monolithic waste materials in the function of time was examined. There was established the cumulative leaching of elements per surface area of waste material and the impact of the duration of the leachant contact with the waste on the leachability. The types of processes accompanying the release of heavy metals were determined as well. Surface wash-off and dissolution were dominant processes during the leaching of the analyzed elements. Chromium was the only element whose release from the sample was controlled by diffusion when subjected to leaching in a liquid of pH 7. Due to the low levels of heavy metal leaching in relation to their concentrations in the samples, it seems that longer duration of the tank test can contribute to the release of additional amounts of the heavy metals.

“…The efforts of many geologists such as Voytekhovsky (2014) and Johanson et al (2014) have contributed to several interesting touristic initiatives, although their routes were created primarily for narrowly focused specialists such as mineralogists and geologists, emphasizing mainly the geological significance of the area. In some places (e.g., Kolvitza region), there are also zones of former mining, the reclamation of which, due to mineralization and climatic conditions, may be troublesome (Jończy et al 2014).…”

The subarctic Kandalaksha region abounds in many tourist values and is notably characterized by a richness of geology, nature, history, and landscape. Its mountains are located directly on the coast of the White Sea. The skerry-fiord coast is the habitat of many seabirds that nest on its many islands. There is also large mammals such as seals and bears. The coastal area and islands are a reserve within the National Park that was established to protect the breeding areas of the seabirds. Despite its location near the Arctic Circle, the area has a relatively mild climate. Many of the villages and towns in the area have a centuries-old history inextricably linked to the indigenous peoples (Karelians, Sami) who inhabited the area, as well as to the “Pomors,” the first Russian colonizers of the area. On top of this, this is a location with an environment that contains numerous examples of flora and fauna, as well as a geologically and geomorphologically interesting landscape connected with glaciation, abrasion, and isostatic movements. Here, the geological substrate, made up of Paleoproterozoic collisional structures of the Lapland Granulite Belt, was repeatedly tectonically rejuvenated within the forming aulacogen of the White Sea and the Kola-Lapland Mobile Belt, along with numerous Paleozoic intrusions of kimberlite and alkaline rocks. The youngest processes are associated with Pleistocene glaciation and isostatic relaxation in the Holocene. All these features contribute to the high tourist potential of the area. At present, it is being developed in a more or less organized way with the participation of private capital. This article presents a proposal for the systematic development of the area in question and the formalization of tourist routes in the area. This article aims to meet this need by proposing a tourist trail in the Kandalaksha area so as to enable tourists to explore this remarkable area.

Natural aggregates from sedimentary rock, like limestone and dolomite, are of a great use in various practical applications. To evaluate their quality, among others, the test of methylene blue adsorption (MB value) using a filter paper is recommended. However, one can consider it as a rough test. In this paper we wished to evaluate its quality by comparison with a more precise spectrophotometric method, i.e., to perform adsorption isotherms of methylene blue from aqueous solutions, as well as determine other parameters characterizing the aggregates. For this purpose, methylene blue adsorption on samples of limestone and dolomite natural aggregates having various grain sizes were studied to assess quality (fine particles content) of the manufactured aggregates. To determine the amount of adsorbed dye two methods were used: the methylene blue stain test and the dye adsorption from its solutions at various concentrations under static conditions. From the linear form of Langmuir adsorption isotherms of methylene blue, the monolayer capacity was determined, and then the specific surface areas of all fractions of aggregates. The structural (N2 adsorption/desorption), textural (SEM/EDS) and crystallographic structure of the aggregates were studied. It was determined that the MB values for 0–2 and MBF for 0–0.125 mm aggregates fractions fulfill the criteria set out in the specifications required for pavement construction. A very good repeatability of the adsorbed amount of methylene blue on the dolomite and limestone aggregates were obtained by these two different methods. These results confirm the reliability of the method blue test used typically in industrial conditions. The measured specific surface areas of limestone and dolomite using N2 adsorption (SBET) are smaller than SMB determined by methylene blue adsorption from aqueous solutions. This is because in aggregates, apart from calcite and dolomite, there is a small admixture of quartz and clay minerals. During N2 adsorption in dry condition, the external surface of the grains is determined, while in the aqueous solution of methylene blue, both the external and inner surfaces of clay minerals are determined.
