“…This Cu concentration also simulates a worst-case scenario, where a significantly higher proportion of metal in relation to pharmaceutical compounds is normally observed. In a different type of experiment, with sediment, this copper concentration was already tested with no significant effect on plant vitality [22]. Experiments with this plant and with lower copper concentrations close to ERL (Effects Range Low [34]) were previously carried out, and no interference of organic compounds (petroleum hydrocarbons) on copper phytoremediation potential was observed [27,28].…”

“…The pharmaceuticals chosen to be tested are representatives of extensively used ones: bezafibrate and paroxetine. P. australis was chosen due to its potential of phytoremediation of different types of compounds, including metals (e.g., [21,22,33]) and pharmaceuticals (e.g., [13,24,25]. In parallel, this study also aimed to confirm in situ the role of different salt marsh plants on metal retention previously observed by collecting sediment samples in vegetated and non-vegetated locations.…”

“…It is a cost-effective, promising, and trustworthy technology and represents a sustainable solution to recover damaged ecosystems, such as estuarine areas [19,20]. Salt marsh plants have been studied to control pollution by phytoremediation [19,21,22], concluding that plants such as Juncus maritimus, Phragmites australis, Spartina patens, Triglochin striata, and Spartina alterniflora have the potential to treat estuaries contaminated with metals and hydrocarbons. More recently, the potential of a plant that can also be found in salt marsh, e.g., P. australis, to remove CECs from water or sediment contaminated with pharmaceuticals, has been evaluated in a few studies, showing promising results [13,[23][24][25].…”

The aim of the present work was to evaluate the influence of two different pharmaceutical compounds (bezafibrate and paroxetine) on the phytoremediation potential of Phragmites australis in an estuarine medium contaminated by copper. Plants were exposed for seven days to a simplified estuarine medium, elutriate solution, with or without sediment. The medium was doped with copper and bezafibrate or paroxetine. P. australis plants were able to accumulate a significant amount of Cu, particularly in their roots (600 and 250 times increase in copper levels in the absence and presence of sediment, respectively), corroborating the phytostabilization potential of salt marsh plants. Metal uptake and translocation was significantly lower in the presence of sediment (Cu in leaves increased 20 times in the absence and only 4 times in the presence of sediment). An effect of either pharmaceutical compound on metal accumulation was not observed (levels of Cu in plants tissues were in general identical) but, in the presence of sediment, both bezafibrate and paroxetine changed Cu solubility in elutriate solution, either decreasing or increasing it. The current study highlights the possible influence the presence of contaminants of different characteristics (inorganic and organic contaminants) can have on salt marsh phytoremediation potential in the long run, and the effects pollutants might have in the environment.

“…One should be aware that rhizosphere microbial communities also have a key role in phytoremediation. In fact, microorganisms can enhance the phytoremediation potential of a plant in different manners: by promoting plant biomass, increasing (phytoextraction) or decreasing (phytostabilization) metal availability in soil, as well as facilitating metal translocation from soil to root (bioaccumulation) or from root-to-shoot tissues (translocation) (Ma et al, 2016;Oliveira et al, 2014;Rajkumar et al, 2012;Silva et al, 2014).…”

Biogas plants receive inputs of different sources of carbon, nutrients, metals and other pollutants from large areas that result in a digestate that is a very complex and concentrated matrix. How to redistribute all these components without causing imbalances in the receiving environments is one of the main questions that arises regarding the reuse of digestate. The main end destinations of digestate within the EU are agriculture, landfill and incineration, in addition to open-mine land reclamation. There are European and country specific end destinations of digestate that have been recently reviewed and made publicly available in an EU commission report. In terms of agricultural application, digestate is seen as a valuable source of carbon and nutrients, but its application is conditioned by disposal limits for nitrogen, phosphorous and metals. Here, we discuss the need for redesign of the process of digestate manipulation in order to increase its value as fertiliser, through addition of compounds, different solid/liquid phases separation or additional treatments. Potential recovery techniques are also discussed. Phytoremediation, the use of plants to uptake metals from different substrates, can be used not only to remove trace metals from the digestate but also for the recovery of metals from plant biomass or their reintroduction into the biodigester. In addition, a combination of landfill with phytoremediation can be a good alternative for the recovery of degraded soils, or for the reclamation of polluted soil for landscape recovery. Another option can be the use of digestate to produce biochar to be applied in agriculture, a technique that increases carbon content in soils while decreasing trace metal bioavailability. Finally, we discuss the new opportunities that are arising for the use of digestate, including microalgae biomass production and bioenergy.

“…Plant associated microorganisms can play an important role in growth and nutritional status improvement (Cabral et al 2016; Ercoli et al 2017; Valliere and Allen 2016), as well as in the detoxification of harmful substances and maintenance of soil structure (Sułowicz et al 2011; Thijs et al 2014; Watts-Williams et al 2017). Indigenous microorganisms living on heavy metal-contaminated sites have often adapted well to the presence of these elements, driven by long-term exposure to site-specific stress factors, and these adaptations can provide useful opportunities for bioremediation at such sites (Giller et al 2009; Oliveira et al 2014; Touceda-González et al 2017; Vivas et al 2003; Yu et al 2014).…”

The aim of this study was to investigate the effect of autochthonous microorganisms present in soil collected from heavy metal (HM) uncontaminated (Pb ≈ 59 mg kg −1 , Cd ≈ 0.4 mg kg −1 , Zn ≈ 191 mg kg −1 ), moderately (Pb ≈ 343 mg kg −1 , Cd ≈ 12 mg kg −1 , Zn ≈ 1876 mg kg −1 ), and highly (Pb ≈ 1586 mg kg −1 , Cd ≈ 57 mg kg −1 , Zn ≈ 3280 mg kg −1 ) contaminated sites on Zea mays elemental composition, physiological status, and growth parameters. For this purpose, half of the collected soil was sterilized and soil characterization was performed. After 45 days of cultivation, the presence of HM in the soil negatively affected photosynthesis and transpiration rates, relative chlorophyll content, anthocyanins index, chlorophyll fluorescence parameters, and content of oxidative stress products (H 2 O 2 and Malondialdehyde) of Zea mays , while soil sterilization had a positive effect on those parameters. Average percentage of colonization of root segments by arbuscular mycorrhiza fungi decreased with an increase of HM contamination in the soil. The increase in shoot concentration of HMs, particularly Cd and Zn, was a result of contaminated soils sterilization. Aboveground biomass of maize cultivated on sterilized soil was 3-fold, 1.5-fold, and 1.5-fold higher for uncontaminated, moderately contaminated and highly contaminated soils respectively when compared to nonsterilized soils. Contrary to our expectation, autochthonous microflora did not improve plant growth and photosynthetic performance; in fact, they had a negative effect on those processes although they did reduce concentration of HMs in the shoots grown on contaminated soils.
