“…Since areas degraded and contaminated with heavy metals usually exhibit adverse conditions for the growth of plants, the application of various types of soil additives results in a stable and positive effect on plant growth and development [25]. The mineral and organic mixtures used in the experiment as additives supporting phytostabilization processes had a significant impact on the yield of above-ground parts of L. perenne.…”

“…Bars marked with different letters differ significantly for the same Ni exposure (p < 0.05) according to the Duncan test mineral and organic mixture stimulates plant growth and affects the phytostabilization process. In other experiment carried out by [25], the introduction of both chalcedonite as well as halloysite to soil, which had been contaminated with nickel caused an increase in the yield of the tested plants.…”

“…Compared with the control treatment, the mixture of compost from food waste and halloysite treatments significantly increased Ni concentration in plant roots as compared to pots in which additives had not been added. In another experiment conducted by Radziemska et al [25,29], the application of an immobilizing additive in the form of chalcedonite and halloysite caused significant increases in heavy metal concentrations in the roots of rye grass.…”

“…Thus, phytotoxicity bioassays can detect any substance capable of generating temporary or long-term stress on the germination capacity of seeds and roots growth [50]. For particular compost concentrations (25,50, and 100%), the inhibition of the root growth was calculated. The results are presented in a graphical form in Fig.…”

“…The characteristic feature of xenobiotic immobilization is that it can take place as a result of metal absorption and accumulation in plant roots, adsorption on the surface of the roots or precipitation in the rhizosphere zone. Literature [24,25] reports Lolium perenne L. to be a suitable species for the revegetation of metal-contaminated soils from metallurgical sites, mine tailings, and metalliferous wastes. Moreover, Smith and Bradshaw [26] defined this species as a facultative metallophyte, this plant produces high dry matter yields and well accumulates metals [27].…”

Purpose An experiment was conducted to evaluate the potential use of a combination of food waste compost with sorbents as immobilizing agents to aid the phytostabilization of Ni-contaminated soil, using Lolium perenne L. (L. perenne). Methods The content of Ni in plants, i.e. total and extracted by 0.01 M CaCl 2 , was determined using the spectrophotometry method. Tests for the phytotoxicity of food waste compost were carried out using Phytotoxkit ™ tests. Results The compost phytotoxicity tests showed that the growth of the roots of L. perenne was slightly stimulated for a compost concentration of 25%, showing the positive impact of this material on plant growth. The biomass of L. perenne in particular organs, Ni content and the properties of soil depended on the dose of a Ni contaminant and the type of mineral and organic mixture incorporated into the soil. Conclusions Ni accumulated predominantly in the roots of the L. perenne. The greatest increase pH was observed after compost with chalcedonite mixture was added to the soil. The application of mineral and organic mixture, containing compost from food wastes and chalcedonite as a soil amendment, tended to reduce the soil total and mobile fraction of Ni more in comparison to the un-amended soil. Graphical AbstractKeywords Aided phytostabilization · Nickel contaminated soil · Food waste compost · Sorbents Statement of noveltyProblems concerning food waste management and disposal worldwide are currently among the most difficult and most topical issues in the organized waste management system. Apart from the least appropriate placing of food waste in landfills, the methods for disposal/recycling of food waste are the production of animal feed and composting. It is considered that the compost may be recycled for the removal of heavy metals from contaminated soils through the use of organic acids, microorganisms and nutrients found in composts. In this manuscript, we show that the mixture of compost from food waste and mineral sorbents (chalcedonite, halloysite), are a promising amendments for co-remediation methods of nickel contaminated soils. These novel soil amendments could be used for enhanced phytostabilization methods.

Areas degraded by industrial activity demonstrate unfavorable chemical and physical conditions, including a high concentration of trace elements (TEs), which reduce the growth and development of appropriate plant cover. For the above reasons, in recent years, the demand for the development of natural and effective technologies for removing particularly hazardous compounds such as TEs from the environment has been growing. Because aided phytostabilization is a relatively new technology, examination of new additions immobilizing TEs in combination with an appropriately selected species plan poses a challenge in environmental protection and engineering. The novelty of this study is in the assessment of the usefulness of previously not applied soil amendments in processes of TEs immobilization in contaminated soils. This study presents the results of a vegetation experiment using a mix of grasses and rarely used mineral soil amendments (halloysite, diatomite, dolomite) for aided phytostabilization of soil originating from an area affected by industrial activity and characterized by high TEs concentrations. Additionally, the degree of phytotoxicity of the examined soils was determined. The greatest above‐ground biomass was observed when diatomite, dolomite, and halloysite were added to the soil. The concentrations of the analyzed TEs in test plants were higher in roots than in the above‐ground parts. This indicates that mineral amendments affected soil properties promoting TEs precipitation and decreasing TEs bioavailability. The highest increase in soil pH was observed after the application of dolomite to the soil. The average contents of Pb, Ni, Cu, and Cr in soil demonstrated the highest reduction after diatomite and halloysite application. The conducted research confirms the possibility of applying the examined soil additives to support phytostabilization of alkaline soil highly contaminated with TEs.
