Field trials of phytomining and phytoremediation: A critical review of influencing factors and effects of additives
Abstract
Plant-based technologies including phytomining, phytoextraction, phytodegradation, phytostabilization and phytovolatilization have drawn much attention during the last decade. To examine the feasibility of these nature-based solutions to accumulate, degrade, stabilize or volatize metal(loid)s and/or organic contaminants, an increasing number of field studies have been conducted. This review critically evaluates influencing factors in phytomining and phytoremediation approaches, including contaminant concentrations, fertilizer application and chelating agent addition, planting characteristics (e.g. plant density, seeding, cropping and harvesting methods), and soil properties (e.g. salinity, soil texture and soil pH). A proper trial design will assure the robustness of the results if these factors were taken into consideration seriously. We also summarized knowledge about additives used in field trials, especially biological waste-derived amendments such as biochar, compost, sewage sludge and manure. According to the literature reviewed, controversy remains whether these amendments can promote the plant performance. In addition, the utilization of microorganisms and transgenic plants in field trials, and the associated biosafety concerns such as horizontal gene transfer were discussed. Future research should examine the ecological risks associated with phytomining and phytoremediation (e.g. the secondary migration of contaminants due to improper handling of harvested plants). I…

Biochar application can increase the resilience and effectiveness of nature-based solutions (NBS) including phytoremediation, constructed wetland, and in-situ bioremediation with native soil microorganisms.
“Furthermore, biochar application can increase the resilience and effectiveness of nature-based solutions (NBS) including phytoremediation, constructed wetland, and in-situ bioremediation with native soil microorganisms (Fig. 2d) (Wang et al. 2020a; Wang et al. 2020e).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
