Abstract (sommario):

Phytoremediation is an alternative biological treatment that can be used to reduce soil or water pollutants. Phytoremediation has the advantage of environmentally friendly waste products and a lower budget compared to physical and chemical processes. In addition, phytoremediation has the weakness of long contaminant absorption times, and quite a few plants that are used as phytoremediation agents die because they are unable to survive the high concentrations of heavy metals contained in polluted media. This study aims to determine the ability of the S. javanica (S. javanica) plant as a phytoremediator for soil contaminated with the heavy metal Zn from industrial wastewater. Phytoremediation lasted for 10 days by contacting artificial Zn wastewater with a concentration of 5 mg/L and as much as 50 ml/day on the test plants. The planting medium used was 100% soil (A1) and 50% homogenized soil with 50% manure (A2). Tests were carried out on each part of the plant and growing medium with contact times of 0, 5, and 10 days of phytoremediation. The plant used as a phytoremediator is Sangitan (S. javanica). The optimum contact time in this study occurred on the 10th day of phytoremediation, and the addition of a 50% dose of organic matter in manure had an effect on the concentration of the heavy metal Zn. The accumulation of heavy metal Zn in plant leaves was greater than in roots, with an average BCF of 0.694 for leaves and 0.308 for roots. While the TF value > 1 represents that the Sangitan plant (S. javanica) has the potential to be a phytoremediator and has a high ability to translocate the heavy metal Zn.

Abstract (sommario):

Contamination of aquatic ecosystems by various sources has become a major worry all over the world. Pollutants can enter the human body through the food chain from aquatic and soil habitats. These pollutants can cause various chronic diseases in humans and mortality if they collect in the body over an extended period. Although the phytoremediation technique cannot completely remove harmful materials, it is an environmentally benign, cost-effective, and natural process that has no negative effects on the environment. The main types of phytoremediation, their mechanisms, and strategies to raise the remediation rate and the use of genetically altered plants, phytoremediation plant prospects, economics, and usable plants are reviewed in this review. Several factors influence the phytoremediation process, including types of contaminants, pollutant characteristics, and plant species selection, climate considerations, flooding and aging, the effect of salt, soil parameters, and redox potential. Phytoremediation’s environmental and economic efficiency, use, and relevance are depicted in our work. Multiple recent breakthroughs in phytoremediation technologies are also mentioned in this review.

Abstract (sommario):

Phytoremediation of hydrocarbon-contaminated soils is a challenging process. In an effort to enhance phytoremediation, soil was artificially contaminated with known concentration of light crude oil containing Total petroleum hydrocarbon (TPH) at a concentration of 75 gkg−1 soil. The contaminated soil was subjected to phytoremediation trial using four plant species (Oryza longistaminata, Sorghum arundinaceum, Tithonia diversifolia, and Hyparrhenia rufa) plus no plant used as control for natural attenuation. These phytoremediators were amended with concentrations (0, 5 and 10 gkg−1 soil) of organic manure (cow dung). Results at 120 days after planting, showed that application of manure at concentrations of 5 and 10 gkg−1 soil combined with an efficient phytoremediator can significantly enhance reduction of TPH compared to natural attenuation or use of either manure or a phytoremediator alone (p<0.05). The study also showed that a treatment combination of manure 5 gkg−1 soil, with a phytoremediator gives a similar mean percentage reduction of TPH as manure 10 gkg−1 soil (p>0.05). Therefore, the study concludes that use of phytoremediators and manure 5 gkg−1 soil could promote the restoration of TPH contaminated-soils in the Sudd region of South Sudan.

Abstract (sommario):

Cadmium (Cd) is one of the most toxic metals in the environment, and has noxious effects on plant growth and production. Cd-accumulating plants showed reduced growth and productivity. Therefore, remediation of this non-essential and toxic pollutant is a prerequisite. Plant-based phytoremediation methodology is considered as one a secure, environmentally friendly, and cost-effective approach for toxic metal remediation. Phytoremediating plants transport and accumulate Cd inside their roots, shoots, leaves, and vacuoles. Phytoremediation of Cd-contaminated sites through hyperaccumulator plants proves a ground-breaking and profitable choice to combat the contaminants. Moreover, the efficiency of Cd phytoremediation and Cd bioavailability can be improved by using plant growth-promoting bacteria (PGPB). Emerging modern molecular technologies have augmented our insight into the metabolic processes involved in Cd tolerance in regular cultivated crops and hyperaccumulator plants. Plants’ development via genetic engineering tools, like enhanced metal uptake, metal transport, Cd accumulation, and the overall Cd tolerance, unlocks new directions for phytoremediation. In this review, we outline the physiological, biochemical, and molecular mechanisms involved in Cd phytoremediation. Further, a focus on the potential of omics and genetic engineering strategies has been documented for the efficient remediation of a Cd-contaminated environment.

Abstract (sommario):

Batik is one of Indonesia's cultural treasures that is popular and worldwide. However, behind the manufacturing process, batik creates textile liquid waste that requires processing because it contains hazardous substances. Kampung Batik Jetis Sidoarjo is one of the locations for batik craftsmen in Indonesia. Textile liquid waste contains a lot of hazardous substances such as dyes, heavy metals, and suspended solids. On average, textile wastewater in Indonesia contains 750 mg/l suspended solids and 500 mg/l BOD. Comparison of COD:BOD is in the range of 1.5:1 to 3:1. Phytoremediation is an environmentally friendly method that is widely used to treat waste. Water hyacinth is a phytoremediator plant used in this activity because it has the ability to absorb pollutants that are cheap and easy to find. Phytoremediation reactor is used to assist the process of Phytoremediation. This activity aims to educate the people of Kampung Batik Jetis in processing textile liquid waste and being able to build a phytoremediation reactor. The benefits obtained are that the hazardous substances in textile wastewater are reduced and are safely disposed of in water bodies. The results obtained in this activity are increasing the knowledge of the people of Kampung Jetis in processing textile liquid waste using a Phytoremediation reactor.

Abstract (sommario):

The Phytoremediation of distillery effluent employing water hyacinth as a phytoremediator has been assessed in terms of reduction in pH, EC,BOD, COD, TSS, TDS, Na and K. the effluent has been treated for 60 days. A significant reduction in all the selected parameters of distillery effluent over zero day value has been observed. A model for studying the phytoremediation potential of water hyacinth (E.crassipes,) against distillery effluent has been developed and analyzed. All parameters exhibited exponential decrease from the start up to 45 days and thereafter showed negligible decrease till the termination of the experiment. The value of absorption coefficient (µ) calculated from the observed as well as estimated values of all parameters have been found comparable. The proposed phytoremediation model establishes that this technique can be profitably employed for the abatement of pollution from industrial waste water.

Abstract (sommario):

Arsenic contamination of the environment is a serious problem threatening the health of millions of people exposed to arsenic (As) via drinking water and crops grown in contaminated areas. The remediation of As-contaminated soil and water bodies needs to be sustainable, low-cost and feasible to apply in the most affected low-to-middle income countries, like India and Bangladesh. Phytoremediation is an aesthetically appreciable and successful approach that can be used for As decontamination with use of the best approach(es) and the most promising plant(s). However, phytoremediation lacks the required speed and sometimes the stress caused by As could diminish plants’ potential for remediation. To tackle these demerits, we need augment plants’ potential with appropriate technological methods including microbial and nanoparticles applications and genetic modification of plants to alleviate the As stress and enhance As accumulation in phytoremediator plants. The present review discusses the As phytoremediation prospects of soil and water bodies and the usefulness of various plant systems in terms of high biomass, high As accumulation, bioenergy potential, and economic utility. The potential and prospects of assisted phytoremediation approaches are also presented.

Abstract (sommario):

Textile industry caused the increase of the heavy metal Zn in soil in the form of sludge. Waste treatment by the phytoremediation method is one of the alternatives of environmental refinement with low cost and high effectiveness. This study used sunflower plants (Helianthus annuusL.) as a phytoremediator. The chelating agent EDTA was added in some treatment to increase the heavy metal absorption. The addition of 1.5 kg sludge on growth media inhibits the sunflower growth. T0K0 treatment has the most efficient result with a total Zn absorption of 101.74 mg/kg. T0K0 treatment was able to reduce Zn up to 96%. In 100% soil treatment, the EDTA additions decreased the ability of sunflower plants to absorb Zn metal in the phytoremediation process. However, in the 40% sludge treatment, the addition of EDTA did not affect the ability of sunflower plants to absorb the Zn metal in the phytoremediation process.

Abstract (sommario):

Mining operations degrade natural ecosystems by generating a large quantity of mine tailings. Mine tailings remain in dams/open ponds without further treatment after valuable metals such as iron ore have been extracted. Therefore, rehabilitation of tailings to mitigate the negative environmental impacts is of the utmost necessity. This review compares existing physical, chemical and amendment-assisted phytoremediation methods in the rehabilitation of mine tailings from the perspective of cost, reliability and durability. After review and discussion, it is concluded that amendment-assisted phytoremediation has received comparatively great attention; however, the selection of an appropriate phytoremediator is the critical step in the process. Moreover, the efficiency of phytoremediation is solely dependent on the amendment type and rate. Further, the application of advanced plant improvement technologies, such as genetically engineered plants produced for this purpose, would be an alternative solution. Further research is needed to determine the suitability of this method for the particular environment.

Synthetic dyes are capable of producing the whole color spectrum on account of their structural diversity but this diversity poses challenges in the degradation of dyeing wastes. Laccases and peroxidases from bacterial or fungal sources and parts of plants in the presence of hydrogen peroxide (H₂O₂) plus a mediator have been exploited in the bioremediation of synthetic dyes. However, intact plants have not found much favor despite their phytoremediation potential. The goal of this research was to further clarify ways by which whole plants bring about decolorization of different types of synthetic dyes. Hydroponically cultivated plants from two dicot families namely Arabidopsis thaliana and sunflowers (Helianthus annuus) were exposed to representative dyes from several classes: monoazo (Methyl Red and Methyl Orange), disazo (Trypan Blue, Evans Blue and Chicago Blue 6B), and arylmethane (Brilliant Blue G, Bromocresol Green, Malachite Green and Phenol Red). Tests were done in presence or absence of externally added H₂O₂, with or without a free radical mediator, 1-hydroxybenzotriazole, using UV-Visible spectrophotometry. The initial rate of decolorization and the overall percentage decolorization was calculated for each dye in the different treatments. Decolorization of the dyes from different classes varied between plant species and depending on the treatment. Except for Methyl Red, all dyes required added H₂O₂ as well as mediator to achieve rapid decolorization. Added H₂O₂ was found to be the limiting factor since it was degraded by plants within a few hours. Both species were able to slowly decolorize dyes upon daily addition of fresh dye even in the absence of added H₂O₂ and mediator, provided that nutrients were supplied to the plants with the dye. A. thaliana was found to be more effective in dye decolorization per gram tissue than sunflower when treated under similar conditions. Analysis of the residual dye solution by ESI/MS did not reveal any potential by-products following the decolorization treatment with plants, suggesting that the plant roots might be trapping the by-products of dye decolorization and preventing their release into the solution. All these findings support the potential application of whole plants for larger scale remediation.

Contaminated water poses a major environmental and human health problem, which may be resolved by using the emerging phytoremediation technology. This plant-based cost-effective approach to remediation takes advantage of the ability of plants to concentrate elements and compounds from the environment, to absorb and transpire large amounts of water, and to metabolize various molecules in their tissues. The city of Manhattan’s Biosolids Farm located near Manhattan, Kansas is using the emerging technology of phytoremediation. The Biosolids Farm remediation began in the mid 1990’s; with a large planting of alfalfa with the goal of absorbing excess nitrates from soil and ground water. In 2004, hundreds of trees were planted, to serve as a protective buffer between the biosolids disposal area and the Kansas River. In 2006, a trench study was installed to improve tree establishment on a sandy outwash area close to the Kansas River using Siberian elm seedlings and rooted cottonwood cuttings from Nebraska and true cottonwood seedlings from Missouri. Treatments included trenching, dairy cattle composted manure, and tree shelters. This planting was done to serve as a vegetative barrier and to aid in reducing nitrate movement into the Kansas River. There were interaction between the tree sources and the trenching, compost and shelter treatments. The treatments showed significant interactions with tree sources with the addition of compost and shelters with a p value of 0.0438, and trenching and compost p-value 0.0021. Tree survival was significantly improved with the use of tree shelters.

Abstract (sommario):

Polychlorinated biphenyls (PCBs) contaminate every compartment of the environment including sediments, water, and air. Although their production has ceased, PCBs continue to contaminate the environment. The properties that make PCBs useful in industrial applications are the same properties that cause them to persistent in the environment. Phytoremediation has been proposed as an in situ treatment option for the remediation of these contaminants. Phytoremediation is the use of green plants to mitigate environmental pollution without excavation or treatment of the contaminated material. Hybrid poplar trees may be a feasible treatment candidate for scavenging airborne PCBs from nearby sources. PCBs are scavenged onto the leaves where a majority of the mass remains.

Abstract (sommario):

Environmental pollution by metals represents a serious risk to human health and to the environment in both urban, industrial and neighboring areas (Ali et al. 2013). Among natural metalliferous soils, serpentine soils have nutrient scarcity and high concentrations of metals (bioavailable Ni 7-100 mg kg-1; total Ni 500-8000 mg kg-1) (Roccotiello et al., 2015; Turgay et al., 2012). These habitats are inhospitable for the most of the plant species, but highly or exclusively preferred hyperaccumulating plants: these species can live and reproduce on these metalliferous soils without showing toxicity symptoms (Rascio and Navari-Izzo, 2011), being able to accumulate metals such as nickel (Ni) at high concentrations in the aboveground biomass (Krämer, 2010). In some taxa of hyperaccumulators, the concentration of metals and metalloids in the shoot biomass is four orders of magnitude greater than in other non-hyperaccumulating species (Kramer 2010). In these taxa, the rhizosphere, defined as the soil-root interface, plays a key role because it represents the first area of exchange and potential uptake of contaminants, where the roots have free access to the elements of the soil (Alford et al. 2010). Improving the effectiveness of the absorption of metals by the root system of native hyperaccumulators, using the rhizospheric microbiota as a natural chelator of metals, allows increasing phytoextraction with consequent increased potential for environmental restoration and significant economic benefits (Rosatto et al. 2019). This study aims to develop an integrated phytoremediation protocol, employing the facultative Ni hyperaccumulator Alyssoides utriculata (L.) Medik., that was of interest for its environmental plasticity (Roccotiello et al. 2017). This species was inoculated with microbial strains isolated from its rhizosphere: the bacterial strain of Pseudomonas fluorescens SERP1, the fungal strain of Penicillium ochrochloron SERP03S and a mixed inoculum consisting of both strains. These strains, investigated in previous studies developed in collaborations with the Mycology laboratory and the Microbiology laboratory of DISTAV, have been proved to be able to grow in synergy, maintaining the morphological traits typical of each species and reaching maturity, without mutual inhibition (Rosatto et al. 2019). The thesis consists into six thematic chapters: Chapter 1 examines the natural and anthropogenic sources of heavy metals and the risks they pose to human health. In particular, the Nickel element is investigated, being naturally present in considerable amounts in serpentinite soils. The metallophytes and their mechanisms of tolerance and accumulation with respect to metals and the role of Nickel (Ni) in plant physiology are then examined, in regard to hyperaccumulating plants and the physiological mechanisms involved in the hyperaccumulation process. Finally, the processes of phytoremediation and the species used for this purpose are described and the integrated phytoremediation technique, a recently developed technique that involves the use of bacterial and fungal strains as root growth promoters to relieve stress from metals, is explored. The objectives of the current study are subsequently described. Chapter 2 illustrates the soil sampling in the field, the experimental design, the monitoring plan in the different months of the experimentation (t0, t6, t12, t18, respectively) and the parameters measured to evaluate the response of the plants under different treatments (control, single bacterial and fungal inoculum, co-inocula mix of bacterial and fungal strains). The accumulation of leaf Ni is qualitatively assessed with dimethylglyoxime (DMG test). The methodology for the isolation and culture of bacterial and fungal strains is described and the measured biometric and ecophysiological plant parameters are described: fresh and dry biomass, photosynthetic efficiency, and performance index of the plants in the experiment. Chapter 3 illustrates the data obtained and the main results. The data analysis revealed that plants inoculated with a single inoculum (bacterial or fungal), compared to control plants without inoculum, have a greater development of belowground and aboveground biomass but do not show and increased accumulation of Ni. The Student T-test for unpaired samples does not highlight any significant differences for both the photosynthetic efficiency (Fv/Fm) and the Performance Index (PI) between the 'control' group and single inoculated ('Bacteria' and 'Fungi') or co-inoculated plants ('Mix'). Furthermore, the data show that there is no further increase in biomass and physiological response in co-inoculated plants compared to those with single inoculum. Chapter 4 illustrates and discusses the main results obtained, highlighting the potential applicability of the proposed methodological approach in the field. In the end, the conclusions (chapter 5) summarize the main evidence and outline future scenarios. Further studies will validate the effectiveness of selected co-inocula in the field in polymetalliferous soils to understand their potential applicability on a larger scale. The study of the possible use of single inocula and co-inocula in heavy metal hyperaccumulators is currently rising and can significantly contribute to set up more sustainable and effective phytoremediation techniques.

Abstract (sommario):

Municipal treated wastewater entering rivers contain biologically active pharmaceuticals capable of inducing effects in aquatic life. Phytoremediation of three of these pharmaceuticals and an herbicide was investigated using Sandbar willow (Salix exigua) and Arabidopsis thaliana. Both plants were effective at removing compounds from solution, with removal of 86% of the synthetic estrogen, 17α-ethynylestradiol, 65% of the anti-hypertensive, diltiazem, 60% of the anti-convulsant, diazepam (Valium®), and 51% of the herbicide atrazine, in 24 hours. Distribution of compounds within roots and shoots, in soluble and bound forms, differed among compounds. Uptake and distribution of pharmaceuticals within the study plants confirmed pharmaceutical behaviour can be predicted based on a physiochemical property, their octanol-water partitioning coefficients. An effective method for detection of 17α-ethynylestradiol within surface water using solid phase extraction and gas chromatography-mass spectrometry was developed. Previously unreported breakdown of 17α-ethynylestradiol into another common estrogen, estrone, during preparative steps and gas chromatography was resolved.

Abstract (sommario):

Phytoremediation is a plant-based remediation process for treating contaminated soils. The overall aim of this thesis was to determine whether phytoremediation could be applied to co-contaminated soils. Copper (Cu) and pyrene, and Chromium (Cr) and Benzo[a]pyrene (B[a]P) were used as contaminants. The first study involved the joint effect of Cu and pyrene or Cr and B[a]P on the early seedling growth of Lolium perenne. Results suggest that co-contamination showed several types of interactions for seedling growth with different combinations of the pollutants. The second study involved the role Brassica juncea and Zea mays during the remediation of Cu and/or pyrene, and Cr and/or B[a]P co-contaminated soils respectively. Brassica juncea and Z. mays showed contrasting results for metal and polycyclic aromatic hydrocarbon (PAH) remediation. The third study compared freshly spiked soils and aged soils. Ageing affected the plant biomass, metal phytoextraction and PAH dissipation in different ways when compared to fresh soils. Finally, the efficiency of ethylenediaminetetraacetic acid-EDTA and/or citric acid as chelators in co-contaminated soils was studied. The combined application of EDTA and citric acid was more effective in co-contaminated soils. The overall findings from the four studies suggest that phytoremediation could be applied to co-contaminated soils.

Abstract (sommario):

Research was conducted to develop a cost effective and environmentally friendly technology to limit the dispersal of metal contaminants from highway traffic in the soil to the surrounding natural environment. The study comprised preliminary field measurements followed by two pot experiments and a field study. The first study evaluated the phytoextraction/ phytostabilisation potential of five plant species: Brassica napus L (rape), Helianthus annuus L. (sunflower), Lolium perenne L (perennial rye grass), Poa pratensis L (Kentucky blue grass) and Festuca rubra L (creeping red fescue) for metals (Cu, Mn, Pb and Zn), in soils with different metal contamination levels. The promising plant species identified were Lolium perenne, Festuca rubra and Poa pratensis. Total soil and plant metal concentrations, as well as the relative metal partitioning in different soil fractions and in plants were determined to provide an estimate of the mobility and potential bioavailability of metals in the soil. The second study evaluated the effectiveness of soil-plant-amendment interaction in immobilising metals in the soil. The amendments included lime, phosphate and compost individually and in combination, and were applied to the plant species: Lolium, Poa and Festuca. Maximum metal immobilisation was achieved in the soil by the combined application of amendments in conjunction with growth of Festuca for Cu, Poa for Pb and Zn and Lolium for Mn. The results obtained from first and second studies were confirmed by conducting field studies. A completely randomized factorial experiment in split plot design with three plant species (Lolium, Poa, and Festuca) individually and in combination, with and without soil amendments was conducted along Highway 17 soil in southwest British Columbia. The influence of root-soil interactions and seasonal influence on the solubility and bioavailability of metals in the soil with and without soil amendments was also evaluated. The best management practices (BMP) developed from the study have the applicability for phytostabilisation of metal contaminated sites and can be suggested as a risk management activity, reducing long-term associated risks.

Abstract (sommario):

Soil is an essential component of all terrestrial ecosystems and is under increasing threat from human activity. Techniques available for removing radioactive contamination from soil and aquatic substrates are limited and often costly to implement; particularly over large areas. Frequently, bulk soil removal, with its attendant consequences, is a significant component of the majority of contamination incidents. Alternative techniques capable of removing contamination or exposure pathways without damaging or removing the soil are therefore of significant interest. An increasing number of old nuclear facilities are entering ‘care and maintenance’, with significant ground contamination issues. Phytoremediation — the use of plants’ natural metabolic processes to remediate contaminated sites is one possible solution. Its key mechanisms include phytoextraction and phytostabilisation. These are analogues of existing remedial techniques. Further, phytoremediation can improve soil quality and stability and restore functionality. Information on the application of phytoremediation in the nuclear industry is widely distributed over an extended period of time and sources. It is therefore difficult to quickly and effectively identify which plants would be most suitable for phytoremediation on a site by site basis. In response, a phytoremediation tool has been developed to address this issue. Existing research and case studies were reviewed to understand the mechanisms of phytoremediation, its effectiveness and the benefits and limitations of implementation. The potential for cost recovery from a phytoremediation system is also briefly considered. An overview of this information is provided here. From this data, a set of matrices was developed to guide potential users through the plant selection process. The matrices take the user through a preliminary screening process to determine whether the contamination present at their site is amenable to phytoremediation, and to give a rough indication as to what plants might be suitable. The second two allow the user to target specific plant species that would be most likely to successfully establish based on prevailing site conditions. The outcome of this study is a phytoremediation tool that can facilitate the development of phytoremediation projects, avoiding the need for in-depth research to identify optimal plant species on a case-by-case basis.
