“…The changes in microbial populations or processes under fieldcontaminated differed from laboratory-spiked (Bååth 1989;Smolders et al 2004), and those with short-term pollution (Frostegård et al 1996;Rajapaksha et al 2004) differed from with long-term pollution (Abaye et al 2005;Ge and Zhang 2011). It was known that the high concentration of heavy metals could affect the microbiota directly through the transformation of the population size, diversity, and structure.…”

“…One explanation for this finding was that bacteria as indigenous microbial in agricultural soil might adapt multiple microhabitats and utilize more labile SOC and form a favorable mechanism against heavy metal. The increased heavy metal tolerance of the microbial community could be due either to an acquired tolerance by adaptation, or to a shift in species composition, where organisms already tolerance became more competitive and thus more numerous (Bååth 1989). In the study done by Ying et al (2009), resistance effect of resistant bacteria was better than that of resistant fungi in microorganism-plant bioremediation for heavy metal (Zn and Cr) contaminated soil.…”

Due to the emerging environmental issues related to heavy metals, concern about the soil quality of farming lands near manufacturing district is increasing. Investigating the function of soil microorganisms exposed to long-term heavy metal contamination is meaningful and important for agricultural soil utilization. This article studied the potential influence of several heavy metals on microbial biomass, activity, abundance, and community composition in arable soil near industrial estate in Zhuzhou, Hunan province, China. The results showed that soil organic contents (SOC) were significantly positive correlated with heavy metals, whereas dehydrogenase activity (DHA) was greatly depressed by the heavy metal stress. Negative correlation was found between heavy metals and basal soil respiration (BSR), and no correlation was found between heavy metals and microbial biomass content (MBC). The quantitative PCR (QPCR) and polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) analysis could suggest that heavy metal pollution has significantly decreased abundance of bacteria and fungi and also changed their community structure. The results could contribute to evaluate heavy metal pollution level in soil. By combining different environmental parameters, it would promote the better understanding of heavy metal effect on the size, structure, and activity of microbial community in arable soil.

“…Total cell numbers in the metal-contaminated soil of Langelsheim were about 1 order of magnitude lower than the average bacterial cell numbers reported for noncontaminated soils (1 ϫ 10 9 bacteria g Ϫ1 [32][33][34]). Nonetheless, the microbial community composition of the Langelsheim soil was typical for soils in general with slight shifts toward an elevated abundance of the phyla Actinobacteria and Proteobacteria, which are known to comprise many taxa that contain metal resistance and tolerance mechanisms (33,(35)(36)(37).…”

The remediation of metal-contaminated soils by phytoextraction depends on plant growth and plant metal accessibility. Soil microorganisms can affect the accumulation of metals by plants either by directly or indirectly stimulating plant growth and activity or by (im)mobilizing and/or complexing metals. Understanding the intricate interplay of metal-accumulating plants with their rhizosphere microbiome is an important step toward the application and optimization of phytoremediation. We compared the effects of a "native" and a strongly disturbed (gamma-irradiated) soil microbial communities on cadmium and zinc accumulation by the plant Arabidopsis halleri in soil microcosm experiments. A. halleri accumulated 100% more cadmium and 15% more zinc when grown on the untreated than on the gamma-irradiated soil. Gamma irradiation affected neither plant growth nor the 1 M HCl-extractable metal content of the soil. However, it strongly altered the soil microbial community composition and overall cell numbers. Pyrosequencing of 16S rRNA gene amplicons of DNA extracted from rhizosphere samples of A. halleri identified microbial taxa (Lysobacter, Streptomyces, Agromyces, Nitrospira, "Candidatus Chloracidobacterium") of higher relative sequence abundance in the rhizospheres of A. halleri plants grown on untreated than on gamma-irradiated soil, leading to hypotheses on their potential effect on plant metal uptake. However, further experimental evidence is required, and wherefore we discuss different mechanisms of interaction of A. halleri with its rhizosphere microbiome that might have directly or indirectly affected plant metal accumulation. Deciphering the complex interactions between A. halleri and individual microbial taxa will help to further develop soil metal phytoextraction as an efficient and sustainable remediation strategy. E levated metal concentrations in agricultural soils decrease the yield and quality of crops. One of these metals is cadmium (Cd), which is present in the waste materials and waters of many industries (1) and in phosphate fertilizers used in agriculture (2, 3). Besides causing a decrease in crop yield (4), Cd is also a risk to human health if larger quantities (Ͼ2.5 g kg Ϫ1 body weight week Ϫ1 , according to the EFSA [5]) are consumed (6-8). To preserve crop yield and quality, sustainable biotechnologies are urgently needed to relieve agricultural soils of metal contaminants. One promising soil remediation technology is phytoremediation-the use of plants for removing inorganic and organic contaminants from soils (9-11). Phytoremediation is attractive, as it is sustainable and relatively inexpensive compared to other soil cleanup strategies. So far, it has rarely been employed on the field scale (12) due to its low efficiency, slow progress, and the need to develop individual implementation strategies depending on the field site conditions and plant type.Arabidopsis halleri has been studied as a model plant for Cd as well as zinc (Zn) hyperaccumulation in order to apply the plant for phytoremediati...

“…Introduction of potential harmful trace metals into the soil involves interaction with the biological processes occurring in the soil and their excessive uptake by plants (Baath, 1989;Chaney and Oliver, 1996), although there is considerable variation between metals in terms of the environmental impact of soil pollution. The industrial pollutant emissions could potentially influence tree ring width and elemental composition of wood and occurs during physiological processes responsible for plant growth.…”

This study reports the variation of tree-ring widths and annual variation of concentration of metals (Na, Mg, Fe, Ni, Cu, Zn, Pb) in pine growing nearby chemical factories. The conifers (Pinus silvestris L.) investigated in this study covered the time span from 1920s to 2010 AD. Tree-ring widths were measured, dated and rechecked using the COFECHA. Radial trace-element profiles were determined by Laser Ablation Inductively Coupled Plasma Mass Spectrometry. The combined usage of tree ring width and chemical composition of wood provides historic records of anthropogenic impact on the environment and allows identifying the behavior adaptation of trees to the pollution. Data of pine tree cores collected from the sites nearby chemical factories show increasing levels of pollution linked to the increasing of industrial activities in Poland and subsequent dust fallout around the site. This study evidences that tree rings can be used as archives of past environmental contamination.
