“…From the hygienic point of view, it is necessary to emphasize that in an area of more than 15 km² (78.5%) was detected an excess of the mercury limit value (0.5 mg/kg). The results of mercury content in the soil closely correlate with the results of other authors, who pointed to the high level of contamination of all environmental elements (Árvay et al, 2017;Bobro et al, 2006;Demková et al, 2017;Dombianová, 2005;Takáč et al, 2008). It represents a significant risk of possible contamination of agricultural production and food and feed chains (Árvay et al, 2014).…”

The level of contamination of the environment in the past few decades is largely influenced by the anthropogenic activity. Among the most burdened areas by the remains of the mining and processing industry in the middle Spiš region, where was treated by mercury - containing ore (cinnabar and tetraedrite) from the middle of 20th century to 1993. About 500 meters from the main processing plant is located tailing pond where landfilled flotation sludge with the content of mercury is more than 46 mg/kg. In the present work, we have focused on the assessment of the level of contamination of the upper horizon (0-0.1 m) of agricultural and forest land in the cadastral territory of Markušovce, where is located the emission source and the pond. We determined 28 sampling points by GPS method on areas of our interest. All soil samples have been subjected to analyses for the detection of the active and the exchange of the soil reaction, the content of humus (%), total concentration of Hg and the concentrations of Cd, Pb, Cu and Zn (mg/kg) in the solution of the aqua regia. The results obtained an extremely high level of contamination of these elements of the contents of the soil. Mercury concentration was in the range of 0.69-90.7 mg/kg, while the median value was recorded exceeding the standard established by applicable legislation over 30 times. The content of other heavy metals closely correlated with contaminant concentration, which varied in wide intervals as evidenced by high relative standard deviations (Cd: 1.62 ± 34.2 mg/kg; Pb: 37.6 ± 60.7 mg/kg; Cu: 23.5 ± 124 mg/kg Zn: 108 ± 40.4 mg/kg). Even in the case of these two elements we have in excess of the limit value at the level of the averages. The results observed that heavy metal concentrations indicate a high level of soil contamination in the study area, which will be reflected to the contamination of other components of environment and food chain.

“…Increased concentrations of heavy metals are often detected in industrial wastewaters, primarily from metallurgical plants, tanneries, petroleum refining, agriculture, and mining [1]. Such heavy metals are non-biodegradable, accumulate in living organisms and can cause various serious diseases and disorders, even at low concentrations [2,3]. Various physical-chemical methods and techniques are used for the removal of metals from wastewater, such as chemical precipitation, ion-exchange, electroflotation, membrane separation, reverse osmosis, electrodialysis, and solvent extraction.…”

This paper reports a study of the removal of heavy metals from water by unconventional waste products including the wooden sawdust of poplar, cherry, spruce and hornbeam. The efficiency of Cu(II), Zn(II), and Fe(II) ion sorption under various initial concentrations from model solutions by raw and alkaline-modified sawdust was investigated. Data obtained by neutron activation analysis revealed that ion exchange is one of the mechanisms underlying metal removal by the selected sawdust from the model solutions. Analysis of the structure and morphology of natural and alkali-modified wooden sawdust by SEM/EDX did not reveal significant changes. The FT-IR spectra showed changes in functional groups due to the alkaline modification of sawdust where the intensity of hydroxyl peaks was considerably increased. It was found that the sorption capacity of the modified sawdust for the model solutions of 50 mg.L-1 of Cu(II) and Zn(II) was approximately 4.5 times higher in comparison to the untreated sawdust; however, the alkaline-modified sawdust had a negative influence on Fe(II) ion removal because of organic-metallic dye formations. The adsorption capacity of the alkaline modified wooden sawdust for the removal of heavy metals from wastewater was improved.

Sediments are normally the final pathway of both natural and anthropogenic components produced or derived from the environment. Sediment quality is a good indicator of pollution in the water column, where heavy metals and other organic pollutants tend to concentrate. Metals are introduced in aquatic systems as a result of the weathering of soils and rocks, from volcanic eruptions, and from a variety of human activities involving the mining, processing, or use of metals and/or substances that contain metal pollutants. Heavy metal concentration in the water column can be relatively low in some cases, but the concentrations in the sediment may be elevated. The presented work aimed to investigate the pollutant levels of some heavy metals (Fe, Mn, Al, Cu, Zn, As, Cd, Pb) in the water and sediments related to acid mine drainage (AMD) produced from an abandoned sulphide mine in Smolnik in Eastern Slovakia. A metal pollution index was used to compare the total content of metals at five sampling stations. The level of partitioning of the metals between the surface water and sediments in the area was calculated using Partition coefficients and the correlation coefficients between the metal pairs in both media were calculated by a Pearson coefficient.
