| Abstract |
The contemporary reclamation method in an opencast coal mine closure comprises the use of the preserved surface soil layer (SSL) before mining, and can be directly returned to the areas being rehabilitated. The present study emphasizes a risk in the use of such a SSL in mine rehabilitation due to the possible excessive amount of heavy metals which usually derives from a metal-rich sediment or fluvial character of overburden material. This indication was approved by the bioassessment of cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), lead (Pb), nickel (Ni), and zinc (Zn) in root and aerial parts of maize (Zea mays), alfalfa (Medicago sativa), sweet clover (Melilotus officinalis), wheat (Triticum aestivum), barley (Hordeum sativum), white clover (Trifolium repens), pasture (Poales sp.), tomato (Solanum lycopersicum), potato (Solanum tuberosum) and carrot (Daucus carota) grown on SSL in the opencast mine area. The fluvial layers of the investigated mine SSL revealed the excessive existence of Ni and Cr, probably of geogenic origin, according to the X-ray diffraction (XRD) which detected Ni- and Cr-bearing minerals in soil fractions. In addition, the highest residual fraction of these two heavy metals, obtained by sequential extraction analyses, together with all other tested soil parameters, supported this assumption. Nevertheless, the accumulations of Cr in tomato fruit (2.93 mg kg(-1)), potato tuber (5.89 mg kg(-1)) and carrot root (7.35 mg kg(-1)) grown on the investigated SSL were found to exceed a critical level of this element for human nutrition. However, despite the evident excess of Ni in the investigated SSL, a similar trend was not found in edible part of plants. The transfer and mobility of the investigated metals was evaluated using the accumulation factor (AF < 1.0) where the root were the preferential organ for the storage of heavy metals. This investigation could bring an important input for its acceptability of use in soil restoration after mining for food/fodder production, or it could indicate the potential risks of the presence of heavy metals regarding its possible use in improving the human surrounding. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 28 March 2017.
All research outputs
#20,656,820
of 25,374,917 outputs
Outputs from Journal of Environmental Management
#5,061
of 6,438 outputs
Outputs of similar age
#244,296
of 317,470 outputs
Outputs of similar age from Journal of Environmental Management
#68
of 91 outputs
Altmetric has tracked 25,374,917 research outputs across all sources so far. This one is in the 10th percentile – i.e., 10% of other outputs scored the same or lower than it.
So far Altmetric has tracked 6,438 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.5. This one is in the 11th percentile – i.e., 11% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 317,470 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 91 others from the same source and published within six weeks on either side of this one. This one is in the 18th percentile – i.e., 18% of its contemporaries scored the same or lower than it.
