AB  - Inorganic materials such as lime, calcium phosphates, and numerous aluminosilicates (red mud, fly ash, synthetic zeolites, clay) are used to immobilize metal/metalloid ions and improve soil quality, contributing to easier revegetation of contaminated soil. Using aided phytoremediation as a technique of choice for soil purification on metal-rich soils reduces the spread of pollutants by wind, soil erosion, and surface runoff. Studies have shown that Festuca rubra can tolerate high concentrations of metals, by using excluding strategies. Geopolymer materials used in this experiment were synthesized from a natural raw kaolinite clay with the addition of 2 wt.%, 4 wt.% and 6 wt.% of brushite (GPB2, GPB4 and GPB6). The main goal of this study is to examine the influence of brushite-metakaolin geopolymer materials on the phytostabilization efficiency of Pb(II) by Festuca rubra. The plant samples were grown using commercial substrate and seeds in eight different series, under controlled conditions. The series involved soil contaminated by Pb(II) treated with selected samples GPB2, GPB4 and GPB6, and the one untreated series and control series. Plant samples were collected after six weeks, and the plant height, fresh biomass, and dry biomass were measured. Germination rates of the plant samples were monitored during the experiment. Heavy metal content in the plant and soil samples was analyzed using atomic absorption spectrophotometer (AAS), and BCF, BAF and TF were calculated. Besides that, pH and organic carbon content in the soil samples were measured. Due to the fact that the starting materials which were used for GPBs synthesis were abandoned kaolinite clay and brushite obtained using green chemistry processes, byproducts of the synthesis are not harmful for the environment. In addition, this procedure contributes positively to the waste reduction.

AB  - Lead (Pb) is one of the most common environmental pollutants and high concentrations of this element can cause numerous symptoms of phytotoxicity. Inorganic amendments immobilize metal/metalloid ions and reduce their bioavailability in the soil by increasing pH or by adsorbing them. Adsorption mechanisms include chemical precipitation, ion exchange, and crystal growth. In this experiment, geopolymer materials were newly synthesized from a natural raw kaolinite clay with 2, 4, and 6 wt % (GPB2, GPB4, and GPB6) of pure brushite addition. Previous research has shown that brushite-metakaolin geopolymer materials can be successfully synthesized and that they have significant efficiency in removing lead ions from aqueous solutions. Plant samples were grown under controlled conditions in eight different series using commercial substrate and seeds. Four series contained lead-contaminated soil and were treated with brushite-metakaolin geopolymer materials, while the other four series, which contained uncontaminated soil, were also treated with brushite-metakaolin geopolymer materials and served as control series. The plant samples were taken after six weeks. Lead concentrations in the different plant and soil samples were analyzed using an absorption spectrophotometer (AAS). BCF, BAF and TF were calculated from the results obtained. Moreover, physiological and biochemical experiments were carried out and total antioxidant capacity, total phenols, free proline and photosynthetic pigments (chlorophyll a, chlorophyll b, and carotenoids) contents were measured in different plant samples. The results show different responses to metal/metalloid toxicity in the control and treated plant samples, confirming that there is a significant influence of brushite-metakaolin geopolymer materials on the phytostabilization efficiency of Festuca rubra. Phytostabilization is an ecofriendly and cost-effective technique that allows the metals/metalloids to be immobilized in the soil by plants, preventing their migration into the surrounding ecosystem and reducing the chances of them entering the food chain.
