“…Bioconcentration factors of trace elements were calculated as concentration in fruiting bodies divided by pseudo-total concentration in soil underneath (both in mg kg −1 ) 37,38 . To interpret the results, a BCF > 1 suggests that fungi have some transporters (active or passive) that can carry trace elements into fungal biomass resulting in accumulation, while a BCF < 1 may indicate the existence of fungal mechanisms against take up of trace elements 30 . In addition, the ratio between trace elements accumulated in the fungal fruiting bodies and those "bioavailable" in the soil (estimated by CaCl 2 extraction)was calculated as a functional transfer ratio 34 .…”

fungi play a key role in the functioning of soil in terrestrial ecosystems, and in particular in the remediation of degraded soils. the contribution of fungi to carbon and nutrient cycles, along with their capability to mobilise soil trace elements, is well-known. However, the importance of life history strategy for these functions has not yet been thoroughly studied. this study explored the soil-fungi relationship of two wild edible fungi, the ectomycorrhizal Laccaria laccata and the saprotroph Volvopluteus gloiocephalus. fruiting bodies and surrounding soils in a mine-spill contaminated area were analysed. isotope analyses revealed Laccaria laccata fruiting bodies were 15 n-enriched when compared to Volvopluteus gloiocephalus, likely due to the transfer of 15 n-depleted compounds to their host plant. Moreover, Laccaria laccata fruiting bodies δ 13 c values were closer to host plant values than surrounding soil, while Volvopluteus gloiocephalus matched the δ 13 c composition to that of the soil. fungal species presented high bioaccumulation and concentrations of cd and cu in their fruiting bodies.

“…According to Buscaroli (2017), plants with both factors (TF and BCF) > 1 are suitable for phytoextraction, while plants with both factors < 1 are suitable for phytoimmobilization. For Majid et al (2012), plants with TF > 1 promote the phytoextraction process, while plants with TF< 1, plant are suitable for phytoimmobilization process.…”

In this paper, the impact of Pontoscolex corethrurus on Acacia mangium growth and its phytoremediation efficiency in metal-contaminated soils were studied in a greenhouse pot culture under four treatments: non contaminated soil-non inoculated, control (C); non contaminated soilinoculated (NcI); contaminated soil-non inoculated (CNi); contaminated soil-inoculated (CI). The results showed that A. mangium growth performance and its Pb, Ni and Cr uptake were significantly (P<0.05) increased under CI treatment. Under CNi treatment, A. mangium uptake more Ni and Cr content in root tissue than in shoot tissue. But for Pb, the greater content was noted in shoot tissue. A. mangium noninoculated preferentially promoted the phytoimmobilization process for Cr and Ni and the phytoextraction process for Pb. However, under CI treatment, the greater content of potential toxic elements (Cr, Ni and Pb) was observed in roots tissue and A. mangium inoculated promoted the phytoimmobilization process for Cr, Ni and Pb. In addition, the phytoextraction efficiency (PEE) of A. mangium increase (ranged 0.1% under CNi to 14% under CI treatment. This study indicates that earthworms can be used to enhance the phytoremediation efficiency of metal-tolerant plant species in contaminated soil.

“…The plant's ability to uptake metals was calculated from the concentration of metals in plant tissues and the concentration of metals in soils [41]. The real phytoavailability of metals was expressed as percentage of metal mass absorbed by the aboveground biomass of ryegrass with respect to the metal mass in soil per each pot [42].…”

Effects of three phosphorus fertilizers on the shoot biomass and on the accumulation of alkali, alkaline earth, and transition metals in the shoots and roots of ryegrass were studied with two contaminated garden soils. Phosphates were added in sustainable quantities in order to reduce the environmental availability of carcinogenic metals (e.g., Cd and Pb) and to enhance the bioavailability of alkali and alkaline earth metals as well as micronutrients needed by plants. Addition of Ca(H2PO4)2 was the most convenient way to (i) limit the concentration of Cd and Pb, (ii) keep constant the transfer of macro- and micronutrient from the soil to the ryegrass shoots, (iii) decrease the availability of metals, and (iv) increase the ratio values between potential Lewis acids and Cd or Pb in order to produce biosourced catalysis. For instance, the real phytoavailability was reduced by 27%–57% and 64.2%–94.8% for Cd and Pb, respectively. Interestingly, the real phytoavailability of Zn was the highest in the least contaminated soils. Even if soils were highly contaminated, no visual toxicity symptoms were recorded in the growing ryegrasses. This indicates that ryegrass is suitable for the revegetation of contaminated gardens. To promote the sustainable ryegrass production on contaminated soils for production of new organic fragrance and drugs in green processes according to REACH (Registration, Evaluation, Authorisation, and Restriction of Chemicals) regulation, two processes should be recommended: assisted phytostabilization of the elements, and then assisted phytoextraction by using chelators.
