AbstractThis investigation focused on plankton inhabiting fishponds, which previously received mine waters from the lead-zinc mine ‘Matylda’, located in southern Poland (Upper Silesia). The purpose of the investigation was to study the effects of chronic and persistent contamination of fishpond bottom sediments with heavy metals originated from the lead and zinc mine. The phyto-and zooplankton in the four fishponds were dominated by diatoms, green algae and rotifers. Plankton composition of the reference non-contaminated pond was different, since Chrysophytes dominated, and Copepoda were the most numerous among zooplankton. In the contaminated fishponds, we observed teratological forms, both for phyto-and zooplankton species, but only as individuals. Our results showed that planktonic communities had adapted to chronic and persistent heavy metal contamination.

Abstract Environmental pollution with heavy metals is a global disaster. This study investigated metal-accumulating ability of plants growing in a lead and zinc mine area located in Hamedan, Iran. Three dominant plants, including Conium maculatum, Stachys inflata, and Reseda lutea, were collected, and the concentrations of Cd, Cu, Pb, Ni, and Zn in the aerial parts of the plants and in the soils, collected from the mine area and out of the mine, were measured via atomic absorption spectrometry. The concentrations of all the metals in the soil of the mine were greater than the control area (1 km out of mine area); Pb, Zn, Cu, Ni, and Cd were 120, 17, 17, 2.6, and 40 times higher than in the control area, respectively. In the studied plants, Pb and Zn were the highest in C. maculatum (1,200 and 820 mg kg−1, respectively). The highest concentrations of Cu, Ni, and Cd were in S. inflata (140, 96, and 20 mg kg−1, respectively). Phytoremediation tests were done using experimental pots, and results indicate that the plant species are effective accumulator plants for the phytoremediation of heavy metal–polluted soils. Specifically, C. maculatum was effective in removing Pb and Zn, S. inflata was effective in reducing Ni, and R. lutea was effective in reducing Cu.

One of the most important influencing factors on the economy of mines with surface and underground exploitation is the correct choice of haulage technology of ore and waste. The paper analyzes the haulage of ore and waste in the Lead and Zinc Mine "Sase" Srebrenica and determines the optimal haulage length on the four excavation blocks for the application of the new haulage system by using the mine trucks from the aspect of set criteria, increasing capacity and reducing haulage costs through the techno - economic analysis and optimization.The optimal haulage length is determined through the calculations of the loader capacity and the possible choice of the truck depending on the stated criteria.
