SETAC Europe 33^rd Annual Meeting, Data-Driven environmental decision-making, April 2023, Dublin

Resumen (en inglés)

Mine driven trace elements’ pollution entails environmental risks and causes soil infertility. In situ techniques such as phytostabilization have become increasingly important to tackle these negative impacts. The aim of this study was to test the individual and combined effects of different aided phytostabilization techniques using substrate from tailings of an old Cu mine (Phy2SUDOE network), characterized by high acidity and deficiency of organic matter and nutrients. The experiment analyzed the growth of Populus nigra cropping in pots containing substrate a amended with compost non inoculated or inoculated with plant growth promoting rhizobacteria or mycorrhizae or a bacterial combination and fungal inoculates. Non-amended, non-planted and non-inoculated reference pots were also prepared. Plants were harvested after three mounths and nutrient content were determined. Then soil was analyzed for several physicochemical and microbiological properties. Joint use of compost, P. nigra plantation, and inoculation with rhizobacteria were the best techniques to reduce toxicity and improve soil fertility, as well as to increase the survival and productivity. The results support the use of organic amendments, tolerant plants, and plant growth promoting rhizobacteria to reduce environmental risk and improve fertility of soils impacted by mining.

PHY2SUDOE. Avanzando en la aplicación de estrategias innovadoras de fitogestión en zonas contaminadas del espacio SUDOE

Resumen
El Informe Final del proyecto Phy2SUDOE resume los trabajos llevados a cado durante el proyecto, y presenta las conclusiones a las que se han llegado.

La colaboración de entidades diversas del Sudoeste de Europa nos ha permitido seguir avanzando en una mejor comprensión del entorno climático y ambiental de esta parte del mundo, y ha facilitado construir un conocimiento compartido
sobre el suelo y sobre su gestión mediante técnicas alternativas a las tradicionales y que son más respetuosas con el
medio ambiente.
Hemos visto que existen varios factores fundamentales para el éxito de la fitogestión: la aplicación de buenas prácticas, el
mantenimiento en el tiempo de la fitogestión, la biomonitorización y la gestión del agua, entre otros.
Tras un proceso que exige paciencia, se han llegado a recrear ecosistemas con múltiples servicios asociados, incluyendo la
producción de biomasa, el control de la contaminación, la estimulación de los organismos del suelo para un ciclo eficiente de los nutrientes y el secuestro de carbono.
Todo ese nuevo conocimiento se ha puesto a disposición pública para que, en el futuro, otros proyectos e investigaciones lo utilicen de base para continuar contribuyendo a la mejora el mundo en el que vivimos.

Micorremediación con sustratos de crecimiento de Agaricus bisporus y Pleurotus ostreatus frente a fitorremediación con Festuca rubra y Brassica sp. para la recuperación de un suelo contaminado con Pb e y-HCH.

Resumen
La micorremediación con sustratos de crecimiento de hongos puede utilizarse para la recuperación de suelos contaminados mixtos debido a los beneficios derivados de las características fisicoquímicas de los sustratos, la actividad de las enzimas extracelulares secretadas por los hongos y la presencia del micelio fúngico. El objetivo de este trabajo fue evaluar el potencial de los sustratos de crecimiento de Agaricus bisporus y Pleurotus ostreatus (sustratos de hongos inoculados frente a sustratos de hongos gastados) para la micorremediación de suelos co-contaminados con plomo y lindano (γ-HCH). Se comparó la eficacia de estas estrategias de micorremediación con la fitorremediación con plantas de Brassica spp. o Festuca rubra, tanto en términos de reducción de los niveles de contaminantes como de mejora de la salud del suelo. Como resultado de la aplicación de los tratamientos de micorremediación se consiguió una mejora de la salud del suelo, en comparación con los tratamientos de fitorremediación y control (sin tratar). La aplicación de sustrato inoculado con P. ostreatus produjo la reducción más significativa de la concentración de γ-HCH (hasta un 88,9% en comparación con los controles correspondientes). En presencia de sustrato de hongo inoculado, los cuerpos fructíferos de P. ostreatus extrajeron más Pb que las plantas de Brassica spp. o F. rubra. La micorremediación con sustratos de crecimiento de P. ostreatus parece una estrategia prometedora para la recuperación de la salud de suelos co-contaminados con Pb y γ-HCH.

3rd Global Soil Biodiversity Conference, March 2023, Dublin

Resumen (en inglés)

The study evaluates the long-term effects on soil functionality of different phytomanagement options in a former Pb/Zn mine in the temperate-humid zone of Spain. The long-term influence of willow (Salix smithiana Willd) plants, either as monoculture or intercropped with alder (Alnus sp.), and soil organic amendments (green compost) or inorganic fertilization (NPK) on several soil enzyme activities was evaluated. Results from phytomanaged soils are compared with those obtained in unplanted soils, untreated or treated with compost. In the absence of compost amendment, the soil enzymatic activities in the willow monoculture plots (with near neutral pH) tended to be even lower than in the unplanted plots. The addition of compost led to an increase in soil organic matter and in all enzyme activities. The highest values were observed in compost amended plots cultivated with willow in co-cropping with alder. When activity values are expressed per carbon unit, the positive effect of compost tended to disappear, except in intercropped plots. The addition of green compost combined with intercropping of willow with alder, appears to be a suitable management to increase and maintain in the long term the functionality of mine tailings soils contaminated with Pb/ Zn/Cd and with pH close to neutrality.

Resumen (en inglés)

In this work, the capacity of different organic amendments to improve water quality and reduce the mobility of metals in mine-tailings was evaluated. A field pilot test was carried out with leaching columns installed on an old Cu mine ore (NW of Spain) which form part of the PhytoSUDOE network. Ten columns were packed with untreated mine tailings (control) or those treated with organic amendments. In each column rhizon-samplers were installed and pore water samples were obtained by suction. Additionally, a bottom leachate sample was collected through a valve installed at the bottom of the column. Porewater and leachate from the control columns were extremely acidic and had a high concentration of Al, Fe and Cu. In these columns, no plant development was observed. The application of organic amendments improved soil conditions, which allowed the establishment of a dense cover of grasses in the rest of the columns. The combined effect of soil amendment and plant growth had a positive impact on water quality and reduced mobility of aluminum and heavy metals.

Resumen (en inglés)

A glasshouse assay with trace element polluted soils from an old Cu mine ore (NW of Spain) which form part of the PhytoSUDOE network was set. The objective was to evaluate improvements induced by the following phytoremediation-related treatments. Three increasingly complex amendments alone or together with plant growth (Populus nigra L. alone and together with Tripholium repens L.) were tested. And three different rhizosphere bioinocula were applied (Plant Growth Promoting Bacteria (PGP), mycorrhiza (MYC), or mixed (PGP+MYC)). After 110 days of growth plants were collected and biomass was weighted and tree length measured. Plant tessue analysis were carried and physical-chemical soil properties were determined. Soil amendment, plant growth and bioinoculation, demonstrated to improve soil fertility and/or plant health within the time span of this study. Particularly, pH levels increased from 3 (highly acidic) to 5 (acidic) in the worst-case scenario, even reaching 7 (neutrality) in the best plots. Organic matter and pH increments were related with polluting metals’ bioavailability decrements. Plants grew the better both with the most complex amendment and the middle one, with few differences due to bioinoculation. Using the less complex amendment (just compost) beneficial effects of bioinoculants were more observable, although plants didn’t thrive very well. On unamended soils plants neither sprouted nor bloomed. The scheme assayed in this study is suitable for phytomanagement of these kinds of soils affected by mining activity. These findings should be tested now at a larger scale.

Resumen (en inglés)

Soil is one of our most important natural resources. Regrettably, the expansion of human activities has resulted in the degradation of the soil resource due to contamination with a myriad of organic and inorganic compounds. The remediation of mixed contaminated soils, i.e. soils contaminated with both organic compounds and metals, is challenging as it requires actions to simultaneously decrease metal-induced risks and organic contaminant concentrations. Here, we evaluated the effect of the addition of zero-valent iron nanoparticles (nanoremediation) and organic amendments (biostimulation) on the rhizoremediation, using Brassica napus plants, of soil simultaneously contaminated with zinc (2500 mg kg ⁻¹) and lindane (100 mg kg⁻¹). We used a factorial design with three factors (amendment, nZVI, plant) to evaluate the impact of the applied remediation actions on lindane and extractable Zn concentrations, as well as on soil health recovery as manifested by the values of different soil microbial indicators. The studied microbial indicators were not negatively affected by nZVI application. The application of nZVI was the most effective factor regarding the targeted reduction in lindane concentration (51% average reduction in nZVI treated soils). The highest reduction in extractable Zn was achieved in the presence of B. napus, nZVI and organic amendments (99 and 95% reduction in horse manure-amended and sewage sludge-amended soils, respectively). The combination of the three factors led to the highest values of soil microbial indicators (although a significant triple interaction was not observed for all parameters), especially when combined with horse manure amendment: in this case, prokaryotic richness increased by 64%, respiration by 376%, eukaryotic abundance by 333%, and prokaryotic abundance by 437%, compared to untreated soils. The combination of remediation approaches (rhizoremediation with B. napus, nanoremediation with nZVI, biostimulation with organic amendments) can help overcome the limitations of each individual strategy.

Resumen

El uso de enmiendas orgánicas, formuladas a partir de residuos, en la restauración de suelos contaminados es una práctica habitual que permite, además de valorizar residuos, mejorar las condiciones de desarrollo vegetal y reincorporar nutrientes a los ciclos biogeoquímicos naturales. No obstante, hay pocos ensayos de campo que permitan evaluar el efecto a largo plazo de esta práctica sobre las propiedades del suelo. El objetivo de este trabajo es estudiar la evolución de las propiedades físicas del suelo en estériles de mina restaurados mediante el uso combinado de enmiendas orgánicas y distintas especies vegetales (Salix viminalis o Agrostis capillaris). Las condiciones físicas del suelo eran muy desfavorables para el crecimiento vegetal en los suelos de mina sin tratar, que presentaban texturas gruesas, elevada densidad, baja porosidad, y baja capacidad de almacenamiento de agua. Las técnicas de fitogestión aplicadas mejoraron la agregación del suelo, redujeron la compactación y aumentaron su porosidad y capacidad de retención de agua. Las características alcanzadas fueron similares a las de los suelos naturales del entorno.

Resumen (en inglés)
The ability of tobacco (Nicotiana tabacum L. cv. Badischer Geudertheimer) for phytomanaging and remediating soil ecological functions at a contaminated site was assessed with a potted soil series made by fading an uncontaminated sandy soil with a contaminated sandy soil from the Borifer brownfield site, Bordeaux, SW France, at the 0%, 25%, 50%, 75%, and 100% addition rates. Activities of sandblasting and painting with metal-based paints occurred for decades at this urban brownfield, polluting the soil with metal(loid)s and organic contaminants, e.g., polycyclic aromatic hydrocarbons, in addition to past backfilling. Total topsoil metal(loid)s (e.g., 54,700 mg Zn and 5060 mg Cu kg⁻¹) exceeded by seven- to tenfold the background values for French sandy soils, but the soil pH was 7.9, and overall, the 1M NH₄NO₃ extractable soil fractions of metals were relatively low. Leaf area, water content of shoots, and total chlorophyll (Chl) progressively decreased with the soil contamination, but the Chl fluorescence remained constant near its optimum value. Foliar Cu and Zn concentrations varied from 17.8 ± 4.2 (0%) to 27 ± 5 mg Cu kg⁻¹ (100%) and from 60 ± 15 (0%) to 454 ± 53 mg Zn kg⁻¹ (100%), respectively. Foliar Cd concentration peaked up to 1.74 ± 0.09 mg Cd kg⁻¹, and its bioconcentration factor had the highest value (0.2) among those of the metal(loid)s. Few nutrient concentrations in the aboveground plant parts decreased with the soil contamination, e.g., foliar P concentration from 5972 ± 1026 (0%) to 2861 ± 334 mg kg⁻¹ (100%). Vulnerability to drought-induced embolism (P50) did not differ for the tobacco stems across the soil series, whereas their hydraulic efficiency (Ks) declined significantly with increasing soil contamination. Overall, this tobacco cultivar grew relatively well even in the Borifer soil (100%), keeping its photosynthetic system healthy under stress, and contaminant exposure did not increase the vulnerability of the vascular system to drought. This tobacco had a relevant potential to annually phytoextract a part of the bioavailable soil Zn and Cd, i.e., shoot removals representing here 8.8% for Zn and 43.3% for Cd of their 1M NH₄NO₃ extractable amount in the potted Borifer soil.

Front. Environ. Sci. 9:661423. doi: 10.3389/fenvs.2021.661423

Resumen (en inglés)
The growing loss of soil functionality due to contamination by metal(loid)s, alone or in combination with organic pollutants, is a global environmental issue that entails major risks to ecosystems and human health. Consequently, the management and restructuring of large metal(loid)-polluted areas through sustainable nature-based solutions is currently a priority in research programs and legislation worldwide. Over the last few years, phytomanagement has emerged as a promising phytotechnology, focused on the use of plants and associated microorganisms, together with ad hoc site management practices, for an economically viable and ecologically sustainable recovery of contaminated sites. It promotes simultaneously the recovery of soil ecological functions and the decrease of pollutant linkages, while providing economic revenues, e.g. by producing non-food crops for biomass-processing technologies (biofuel and bioenergy sector, ecomaterials, biosourced-chemistry, etc.), thus contributing to the international demand for sustainable and renewable sources of energy andrawmaterials for the bioeconomy. Potential environmental benefits also include the provision of valuable ecosystem services such as water drainage management, soil erosion deterrence, C sequestration, regulation of nutrient cycles, xenobiotic biodegradation, and metal(loid) stabilization. Phytomanagement relies on the proper selection of (i) plants and (ii) microbial inoculants with the capacity to behave as powerful plant allies, e.g., PGPB: plant growthpromoting bacteria and AMF: arbuscular mycorrhizal fungi. This review gives an up-to-date overview of the main annual, perennial, and woody crops, as well as the most adequate cropping systems, presently used to phytomanage metal(loid)-contaminated soils, and the relevant products and ecosystems services provided by the various phytomanagement options. Suitable bioaugmentation practices with PGPB and AMF are also discussed. Furthermore, we identify the potential interest of phytomanagement for stakeholders and end-users and highlight future opportunities boosted by an effective engagement between environmental protection and economic development. We conclude by presenting the legal and regulatory framework of soil remediation and by discussing prospects for phytotechnologies applications in the future.

Resumen (en inglés)
Soils of abandoned and vacant lands in the periphery of cities are frequently subjected to illegal dumping and can undergo degradation processes such as depletion of organic matter and nutrients, reduced biodiversity, and the presence of contaminants, which may exert an intense abiotic stress on biological communities. Mycorrhizal-assisted phytoremediation and intercropping strategies are highly suitable options for remediation of these sites. A two-year field experiment was conducted at a peri-urban site contaminated with petroleum hydrocarbons and polychlorinated biphenyls, to assess the effects of plant growth (spontaneous plant species, Medicago sativa, and Populus × canadensis, alone vs. intercropped) and inoculation of a commercial arbuscular mycorrhizal and ectomycorrhizal inoculum. Contaminant degradation, plant performance, and biodiversity, as well as a variety of microbial indicators of soil health (microbial biomass, activity, and diversity parameters) were determined. The rhizosphere bacterial and fungal microbiomes were assessed by measuring the structural diversity and composition via amplicon sequencing. Establishment of spontaneous vegetation led to greater plant and soil microbial diversity. Intercropping enhanced the activity of soil enzymes involved in nutrient cycling. The mycorrhizal treatment was a key contributor to the establishment of intercropping with poplar and alfalfa. Inoculated and poplar-alfalfa intercropped soils had a higher microbial abundance than soils colonized by spontaneous vegetation. Our study provided evidence of the potential of mycorrhizal-assisted phytoremediation and intercropping strategies to improve soil health in degraded peri-urban areas.

Resumen (en inglés)
The phytomanagement concept combines a sustainable reduction of pollutant linkages at risk-assessed contaminated sites with the generation of both valuable biomass for the (bio)economy and ecosystem services. One of the potential benefits of phytomanagement is the possibility to increase biodiversity in polluted sites. However, the unique biodiversity present in some polluted sites can be severely impacted by the implementation of phytomanagement practices, even resulting in the local extinction of endemic ecotypes or species of great conservation value. Here, we highlight the importance of promoting measures to minimise the potential adverse impact of phytomanagement on biodiversity at polluted sites, as well as recommend practices to increase biodiversity at phytomanaged sites without compromising its effectiveness in terms of reduction of pollutant linkages and the generation of valuable biomass and ecosystem services.

Resumen (en inglés)
Brownfield surface is expanding in Europe, but as often abandoned or underused, these areas become refuge for microbial, faunal and floral biodiversity. However, brownfield sites are generally contaminated, likely posing severe environmental risks. At a former wood preservation site contaminated with Cu, we evaluated the efficiency of compost and dolomitic limestone incorporation into the soil, followed by revegetation with Cu-tolerant grassy species, as a phytomanagement option to increase vegetation cover and plant diversity while reducing pollutant linkages. 7 years of phytomanagement enhanced natural revegetation through the improvement of soil physicochemical properties, particularly with compost-based amendments. The compost incorporation increased soil Cu solubility; however, no increment in Cu availability and a reduction in Cu-induced phytotoxicity were observed with the compost. The improved soil nutrient availability and the soil phytotoxicity mitigation in compost-amended soils facilitated over the 7 years the growth of beneficial plant colonists, including leguminous species, which can potentially promote essential soil functions. Soil treatments did not affect Cu uptake and translocation by plants and shoot Cu levels indicated no risk for the food chain. Overall, a long-term phytomanagement combining an initial amendment of compost and dolomitic limestone with the cultivation of Cu-tolerant grassy populations can ameliorate such Cu-contaminated soils, by mitigating risks induced by Cu excess, ultimately allowing the development of a meadow that can provide ecological and economic benefits in terms of ecosystem services.
