“…Here, high levels of heavy metals were found not only in soil, water or sediment samples (Angelovičová et al 2014;Holub et al 2015;Singovszká et al 2015), but several studies detected extremely high levels of heavy metals in plants (Banasová & Lackovicová 2004; or animal products (Stanovič et al 2016).…”

Demková L., Jezný T., Bobuľská L. (2017): Assessment of soil heavy metal pollution in a former mining area -before and after the end of mining activities. Soil & Water Res., 12: 229−236.Toxicity and persistence of heavy metals, which are accumulated in the environment as the result of diverse industrial activities, represent serious environmental problem worldwide. The intense mineral extraction in mining areas has produced a large amount of waste material and tailings, which release toxic elements to the environment. The aim of the study was to determine in two time horizons (1997, 2015) the heavy metal contents of samples derived from ten sampling sites located in the former mining area of Central Spiš (Slovakia). In order to compare the level of contamination, the contamination factor (C i f ), degree of contamination (C d ), and pollution load index (PLI) were computed. Spearman's correlation coefficient was used in order to detect the relationships among heavy metals. A serious situation was found for Hg, Zn, and Cd, which exceeded limit values at all sampling sites within both studied years. In 1997, the average values of contamination factor have shown very high contamination with all studied heavy metals, and moderate contamination with Co. In 2015, the study area was classified as very highly contaminated with As, Hg, Zn, Cu, considerably contaminated with Ni, Cr, Pb, and Cd, while Co contamination was not detected. Since 1997 till 2015 the pollution load index decreased by about 38%, nevertheless even then almost all sampling sites were classified as heavily polluted. Despite the fact that mining activities were stopped or limited at the beginning of the 21 st century, the presence of heavy metals in soils remains at a serious level. The high level of contamination is a result of heavy metal persistence and non-biodegradability.

“…Generally, metals are known to inhibit soil enzyme activities (Angelovicova et al 2014;Pan and Yu 2011;Belyaeva et al 2005;Kizilkaya and Bayrakli 2005;etc. ); however, according to the results obtained in this study, enzyme activities were not affected by increases in metal concentrations.…”

Past mining activities in Swaziland have left a legacy of abandoned mine sites (iron ore, asbestos, diamond and coal mine dumps), all of which have not been reclaimed. These sites were recently (2013) considered by the country's wastewater treatment authorities as suitable places where biosolids can be applied, firstly as a biosolids disposal alternative and, secondly, as a strategy to accelerate mine soil remediation through phytostabilization. In order to understand the effects that this might have on mine soil conditions and microbiota, two (2) plant growth trials were conducted in biosolid-treated iron mine soils and one (1) trial on undisturbed soil, under greenhouse conditions, for twelve (12) weeks. According to the results obtained, the combination of biosolids and plants led to significant improvements (p \ 0.05) in parameters related to soil fertility. Significant increases (p \ 0.05) in alkaline phosphatase, b-glucosidase and urease soil enzyme activities were also observed. Copper and zinc were significantly (p \ 0.05) increased (Cu from 17.00-50.13 mg kg ); however, these sludge-derived metals did not affect enzyme activities. Improvements in soil physicochemical conditions, organic matter-metal complexes, effects of plants on metals and the essentiality of Cu and Zn to soil enzymes were thought to have masked the effects of metals. Increases in soil enzyme activities were considered to be indicative of improvements in the quality, fertility health and self-purification capacity of iron mine soils due to synergistic effects of biosolids and plants.

Introduction. Mercury release in the environment is mainly the result of human activity, particularly from coal-fired power stations, residential heating systems, waste incinerators, and as a result of mining for mercury, gold and other metals, which have led to widespread global mercury pollution. Excessive exposure to mercury is associated with a wide range of adverse health effects, including damage to the central nervous system, digestive and immune systems, and to lungs, kidneys, skin and eyes. Objective. The main aim of the study is to summarize the selected mercury sources in the environment of the Slovak Republic, regarding waste incinerators, landfill waste, crematoria, chemical plants, rivers and soils. Brief description of state of knowledge. Although the neurologic symptoms of Minamata disease were identified sufficiently for specialists to classify mercury as the causative agent, the acceptance of mercury´s environmental impacts will require several decades of research. Several new issues have arisen-the need for energy conservation leads to the use of fluorescent lighting, which contain mercury; emissions driven by increases in coal combustion, incineration and economic development have sent more mercury into the air, soil and water. Conclusions. Mercury is toxic to human health, posing a particular threat to the development of the child in utero and early in life. The systematic analytical controls of contaminants in water, soil and air are important. The installation of modern cleaning technologies to comply with the maximum emission level can substantially minimized the environmental impact of incinerators. Since human cremation is also an increasing practice, further research on mercury emissions is necessary.
