“…In addition to anthropogenic Hg contamination, natural Hg enrichments exist along the global mercuriferous belts found along Earth plate margins leading to largescale Hg mineralization zones: Circum-Pacific, Mediterranean, Central Asia and Mid Atlantic Ridges, with many Hg mines distributed along these zones 245 . When exposed to high soil and atmospheric Hg levels, plant growth may be decreased due to Hg toxicity [246][247][248][249] . However, most plants grow normally under lightly to moderately polluted areas, but will show substantial Hg enrichments in their tissues.…”

In this review, we synthesize the current knowledge on mercury (Hg) content and sources in foliage and vegetated ecosystems and the importance of vegetation to global Hg cycling. By means of a global database of over 35,000 samples across 416 sites, we discuss global Hg concentrations in all major tissues, and mechanisms of vegetation Hg uptake. Hg in aboveground vegetation largely originates from uptake of atmospheric gaseous elemental Hg (Hg(0)), whereas Hg in roots originates from a combination of uptake from soil and foliage-to-root transport. Vegetation Hg uptake from the atmosphere and transfer to soils is the major Hg source in all biomes. Using model sensitivity analyses with and without global vegetation present, we show that vegetation Hg uptake modulates atmospheric Hg(0) seasonality in the northern hemisphere and interhemispheric gradient. We estimate that vegetation uptake the global Hg pool in the atmosphere by approximately 660 Mg and reduces the Hg deposition to global oceans, which in the absence of vegetation might receive an additional 960 Mg yr -1 . We discuss future research needs to better constrain vegetation uptake mechanisms and their controlling physiological and environmental variables, improve model processes and address effects of climate and land use changes.

“…Phytostabilization immobilizes Hg in soil through biochemical processes, either via Hg accumulation in roots or chelating Hg in the root zone. Candidate plants used for phytostabilization have extensive root systems, are tolerant to Hg toxicity, and are adaptive to site-specific environments [246][247][248][249] .…”

“…The concentration of Pb in the roots of the control treatment was higher by 40% and 30% than in the case of LL_I and LL_II, respectively, and for Zn by 18% and 48%. It might be attributed to the absorption of the metal on the root surface which, consequently, limits the transport to the aboveground parts of the plant (Pogrzeba et al 2019). Radziemska et al (2018) reported a reduction of Cu concentration in the aboveground parts of L. perenne after the application of lime and diatomite to the soil.…”

Arbuscular Mycorrhizal Fungi that colonize the roots of plants growing on lands contaminated by heavy metals may influence the phytostabilization process reducing the translocation of metals to the aboveground parts of the plant. This study aimed to evaluate the effects of soil amendments (lime and lignite) on the concentration of the bioavailable form of heavy metals (CaCl2 extraction) in soil and on the colonization of Arbuscular Mycorrhizal Fungi in the roots of Lolium perenne when cultivated in contaminated soil. During the experiment, the bioavailability of Pb, Cd, and Zn in soil was significantly reduced after application of the amendments, causing an increase of L. perenne shoot dry biomass. It was observed that the higher dose of lime (0.5%) resulting in amplified values of relative mycorrhizal intensity. However, independently of the dose, the treatments increased the occurrence of arbuscules in L. perenne roots, with the highest value observed after the application of 0.25% lime with 5% lignite. The results for the first time present the effect of lime and lignite application on the L. perenne roots colonization by Arbuscular Mycorrhizal Fungi indicating the increase of occurrence of arbuscules. These findings suggest that in order to explain the different responses of Arbuscular Mycorrhizal Fungi to the applied treatment further investigations are needed to identify the spore morphology. The results of the experiment were implemented to stabilize heavy metals during remediation of a spoil heap in Ruda Śląska, Poland.

“…Aided phytostabilisation can be a solution to reduce the mobility of trace elements (Pb, Cd, Zn) in the soil. Various reports consider different organic [ 27 , 28 ] and mineral additives [ 29 , 30 , 31 ] with and without plants to reduce the mobility of these elements in the soil. One of the most studied is biochar of different origins [ 32 , 33 , 34 ].…”

Climate change and man-made pollution can have a negative impact on the establishment of Miscanthus plants in the field. This is particularly important because biomass can be produced on marginal land without conflicting with food crops. The establishment success depends on the hybrid chosen, the cultivation method, the climatic conditions, and the concentration of pollutants in the soil. There are several ways to increase the survival rate of the plants during the first growing season and after the first winter. One of them is the application of biochar and photodegradable plastic mulch, which can provide a solution for soils polluted with trace elements (TMEs). The aim of this study was to investigate the application of plastic mulch and biochar separately and in combination at the planting stage for two Miscanthus hybrids planted by the rhizome method (TV1) and seedling plugs (GNT43) on soils contaminated with trace metal elements (Pb, Cd, Zn). TV1 seems unsuitable for TME-contaminated field cultivation, as the survival rate was <60% in most treatments studied. The selected treatments did not increase the survival rate. Furthermore, the application of plastic mulch in combination with biochar resulted in a significant reduction of this parameter, regardless of the hybrid studied. The applied agrotechnology did not influence the TME accumulation in the aboveground plant parts in TV1, while Pb and Cd in GNT43 showed significantly higher values in all treatments. Contrary to expectations, biochar and plastic mulch applied separately and together neither increased survival nor reduced the accumulation of toxic TMEs during establishment on soil contaminated with TMEs and after the first growing season.
