“…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.

“…LIU et al (2017) reported that the majority of bacteria are inhibited by toxic metals, while sphingomonas bacteria are highly tolerant to heavy metals, thereby having the potential to repair heavy metal contamination. Soil grain size also affects soil microbial abundance and heavy metal adsorption in soil (SINGOVSZKA et al, 2015). Further experiments will be carried on these factors in our future study.…”

“…Under this contamination, there are certain safety risks, thus safe production technology is advocated. Soil Cd adsorption and desorption capacity is related to the size of soil particles (SINGOVSZKA et al, 2015). It is considered that the larger the soil particles are, the stronger the cadmium adsorption capacity is.…”

Soil cadmium extraction in Chinese cabbage and cabbage intercropping

et al. 2019

Toxic metals contamination of soil has become a serious problem in recent years. In this study, Chinese cabbage (a relatively high-accumulator of cadmium (Cd)) and cabbage (a relatively low-accumulator of Cd) were cultured in monoculture and in intercropping in the Cd-contaminated soil, to evaluate the effect of intercropping on the alteration of Cd extraction. Both the pot experiments and field experiments indicated that intercropping increased the Cd extraction by Chinese cabbage and decreased the Cd extraction by cabbage. Thus, Cd extraction was advanced while safe production was obtained. Further pot experiment was conducted to investigate the alterations of soil Cd fractions, soil pH, and soil enzyme activities to reveal their possible relationship with Cd extraction between different planting patterns. Results revealed that three individual Chinese cabbages in one intercropping pot played the same effect on alteration of these factors as six individual Chinese cabbages in one monoculture pot. The intercropping increased Cd extraction by Chinese cabbage and decreased Cd extraction by cabbage, probably by influencing mechanisms such as soil enzyme activities (especially the urease activity) in the cultivation system. Effect of intercropping on Cd accumulation is an important issue in cultivation of vegetables in potentially contaminated land.

“…The Pech shaft receives the majority of water drainage from the flooded Smolnik mine area and discharges it in the form of acid mine drainage (pH 3-4, Cu 3-1 mg/l; Zn 13-8 mg/l, Mn 32-19 mg/l, and As 54-18 μg/l). Increases in pH due to AMD mixing with surface water are followed by metal precipitation and sedimentation in the aquatic environment [31,32]. Guidance on sampling of rivers and streams.…”

The present study was conducted to investigate the heavy metal (Mn, Cu, Zn, As, and Cd) concentration of surface water in Smolnik creek in Slovakia. Furthermore, the study was aimed to determine the potential environmental health risk that the heavy metal concentration poses to the public. The values of the ecological potential index for the water in the study area were more than 600, reflecting a very high risk from the water body posed by these metals. Thus, this was also the reason to examine the impact of these heavy metals on the health of the population. Based on the heavy metal concentration, health risk assessments such as the chronic daily intake and hazard quotient (HQ) were calculated. Results showed that the daily intake of the heavy metals from all five samples taken from Smolnik creek was lower among adults than among children for two pathways of exposure. The non-carcinogenic hazard quotients of heavy metals in the studied area were higher among adults than among children. At all five sites, the HQ values for dermal exposure for adults were higher than 1. The HQ values for exposure through ingestion for adults and children were higher than 10 for almost all sites, indicating a disaster situation.
