“…Mining activities adversely affect the quality of surrounding soils and aquifers and threaten human health and ecosystems (Anjos et al 2012;Rodríguez et al 2009). Studies on the relationship between mining and microbial communities in surrounding soils mainly focused on nonferrous metals (e.g., Cu, Pb, and Sb), which are highly toxic to soil biota (Zhang et al 2007).…”

Mine activities leaked heavy metals into surrounding soil and may affected indigenous microbial communities. In the present study, the diversity and composition of the bacterial community in soil collected from three regions which have different pollution degree, heavy pollution, moderate pollution, and non-pollution, within the catchment of Chao River in Beijing City, were compared using the Illumina MiSeq sequencing technique. Rarefaction results showed that the polluted area had significant higher bacterial alpha diversity than those from unpolluted area. Principal component analysis (PCA) showed that microbial communities in the polluted areas had significant differences compared with the unpolluted area. Moreover, PCA at phylum level and Matastats results demonstrated that communities in locations shared similar phyla diversity, indicating that the bacterial community changes under metal pollution were not reflected on phyla structure. At genus level, the relative abundance of dominant genera changed in sites with degrees of pollution. Genera Bradyrhizobium, Rhodanobacter, Reyranella, and Rhizomicrobium significantly decreased with increasing pollution degree, and their dominance decreased, whereas several genera (e.g., Steroidobacter, Massilia, Arthrobacter, Flavisolibacter, and Roseiflexus) increased and became new dominant genera in the heavily metal-polluted area. The potential resistant bacteria, found within the genera of Thiobacillus, Pseudomonas, Arthrobacter, Microcoleus, Leptolyngbya, and Rhodobacter, are less than 2.0 % in the indigenous bacterial communities, which play an important role in soil ecosystem. This effort to profile the background diversity may set the first stage for better understanding the mechanism underlying the community structure changes under in situ mild heavy metal pollution.

The element contents of sessile oak (Quercus petraea L.) leaves which grow on hydrothermally altered area with high element contents were studied at Gümüşhane and its near vicinity. The aim of this study is to determine threshold element contents of Q. petraea L. leaves growing on the area. For this purpose, oak leave samples collected were analyzed by inductively coupled plasma-mass spectrometry for concentrations of some elements which were the group of most common trace elements in exploration geochemistry studies. The assessment of the element contents of the oak leaf is based on the descriptive statistics and computations of threshold values of leaves depending on statistical parameters and average element contents of the plants growing on lands in normal background values for the elements. According to Q-Q (normal quantile-quantile) plots, the Kolmogorov-Smirnov tests etc., all the elements, do not pass normality tests. Because of that, threshold values of the elements in leaves of oak were computed by median+median absolute deviation (MAD) and median+2MAD used in raw values for the elements. The data revealed that concentration levels of the examined elements in the leaves in the study area were determined as above and/or exceeded the upper limit of the normal range than in leaf of oak (Q. petraea L.) which grows on lands with normal elements background. Therefore, it is concluded that leaves of Q. petraea L. can be used as bioindicator in exploration geochemistry, especially for base metal ore deposits.
