“…Its spores were found in deeper soil layers (20-40, 40-60 cm) where the concentration of bioavailable Cd and Zn was still high when compared to the concentration of bioavailable metals reported by other authors [19,48,55,64]. Two other species Funneliformis mosseae and Archaeospora trappei were represented by 2 and 1 spore respectively (Tab.…”

“…Zarei et al [55,63,64] found from 60 to 131 spores per 150 g of dry soil at a site adjacent to a Zn and Pb open pit mine. Pawłowska et al [65] determined 30-38 spores per 150 g of substrate from calamine spoil mound, del Val et al [19] 45-345 spores per 150 g of soil contaminated by addition of sewage sludge and Wu et al [66] 132-492 spores per 150 g of soil contaminated by As/Pb/Zn mines.…”

“…4). Of the three morphologically distinctive AMF species found in the rooting zone of D. cespitosa only Funneliformis mosseae was detected many times in metal contaminated soils [19,55,64,[66][67][68][69][70].…”

“…There are a few papers on G. tenue colonizing roots of plants growing in soils contaminated by heavy metals [71,72,77]. Most studies dealing with the AMF at such sites did not consider the fungus [19,55,64,[66][67][68][69][70]. Therefore further studies on the occurrence and role of G. tenue occurring alone and with other AM fungi in the roots of plants colonizing contaminated sites are needed.…”

Arbuscular mycorrhiza of Deschampsia cespitosa (Poaceae) at different soil depths in highly metal-contaminated site in southern Poland

This study presents root colonization of Deschampsia cespitosa growing in the immediate vicinity of a former Pb/Zn smelter by arbuscular mycorhizal fungi (AMF) and dark septated endophytes (DSE) at different soil depths. AMF spores and species distribution in soil profile were also assessed. Arbuscular mycorrhiza (AM) and DSE were found in D. cespitosa roots at all investigated soil levels. However, mycorrhizal colonization in topsoil was extremely low with sporadically occurring arbuscules. AM parameters: frequency of mycorrhization of root fragments (F%), intensity of root cortex colonization (M%), intensity of colonization within individual mycorrhizal roots (m%), and arbuscule abundance in the root system (A%) were markedly higher at 20–40, 40–60 cm soil levels and differed in a statistically significant manner from AM parameters from 0–10 and 10–20 cm layers. Mycorrhizal colonization was negatively correlated with bioavailable Cd, Pb and Zn concentrations. The number of AMF spores in topsoil was very low and increased with soil depth (20–40 and 40–60 cm). At the study area spores of three morphologically distinctive AMF species were found: Archaeospora trappei, Funneliformis mosseae and Scutellospora dipurpurescens. The fourth species Glomus tenue colonized roots of D. cespitosa and was observed in the root cortex at 20–40 and 40–60 soil depth, however, its spores were not found at the site.

“…According to Chaney et al (2007), several studies have focused on developing Pb extraction technologies with B. juncea (Zarei et al 2010), whereas in reality, even if there was enough phosphate present in contaminated soils to give good crop yields, most Pb remains in the soil or the roots and, without soil amendments, B. juncea has little ability to absorb Pb from contaminated soils.…”

The ability of heavy metals bioaccumulation to cause toxicity in biological systems-human, animals, microorganisms and plants-is an important issue for environmental health and safety. Recent biotechnological approaches for bioremediation include biomineralization (mineral synthesis by living organisms or biomaterials), biosorption (dead microbial and renewable agricultural biomass), phytostabilization (immobilization in plant roots), hyperaccumulation (exceptional metal concentration in plant shoots), dendroremediation (growing trees in polluted soils), biostimulation (stimulating living microbial population), rhizoremediation (plant and microbe), mycoremediation (stimulating living fungi/mycelial ultrafiltration), cyanoremediation (stimulating algal mass for remediation) and genoremediation (stimulating gene for remediation process). The adequate restoration of the environment requires cooperation, integration and assimilation of such biotechnological advances along with traditional and ethical wisdom to unravel the mystery of nature in the emerging field of bioremediation. This review highlights better understanding of the problems associated with the toxicity of heavy metals to the contaminated ecosystems and their viable, sustainable and eco-friendly bioremediation technologies, especially the mechanisms of phytoremediation of heavy metals along with some case studies in India and abroad. However, the challenges (biosafety assessment and genetic pollution) involved in adopting the new initiatives for cleaning-up the heavy metals-contaminated ecosystems from both ecological and greener point of view must not be ignored.
