“…In Elodea canadensis plants exposed to 15 µg and 250 µg As L −1 , foliar As concentration reached 0.34 and 0.4 mg As kg −1 , and roots 0.34 and 4.3 mg As kg −1 , as an excluder (Picco et al 2019 ). These plants can filtrate As from tap water of an Argentine city located in an As-endemic area from 36 µg As L −1 to undetectable levels (10 ng As L −1 ).…”

Owing to their roles in the arsenic (As) biogeochemical cycle, microorganisms and plants offer significant potential for developing innovative biotechnological applications able to remediate As pollutions. This possible use in bioremediation processes and phytomanagement is based on their ability to catalyse various biotransformation reactions leading to, e.g. the precipitation, dissolution, and sequestration of As, stabilisation in the root zone and shoot As removal. On the one hand, genomic studies of microorganisms and their communities are useful in understanding their metabolic activities and their interaction with As. On the other hand, our knowledge of molecular mechanisms and fate of As in plants has been improved by laboratory and field experiments. Such studies pave new avenues for developing environmentally friendly bioprocessing options targeting As, which worldwide represents a major risk to many ecosystems and human health.

“…Duman y Ozturk (2010), trabajaron con Nastur-tium officinale exponiéndolo a níquel obteniendo resultados similares a los encontrados en este estudio. En otros estudios se ha observado el mismo comportamiento tal es el caso de Pistia stratiotis (Das et al, 2014), Eichhornia crassipes , Elodea canadensis (Picco et al, 2019) Typha latifolia y Juncus effusus (Favas et al, 2012). Shi et al (2011), sugieren que plantas con características similares a las encontradas en el presente estudio sean consideradas especies estabilizadoras de metales pesados o rizofiltradoras (Olmos-Márquez et al, 2012).…”

La contaminación por metales pesados ha aumentado con los años debido a sus diferentes aplicaciones. Se han evaluado distintas especies vegetales para bioacumular metales pesados, el berro es una especie con capacidad de fitorremediación. Sin embargo, falta información sobre la sinergia que ocurre cuando dos metales en el medio están presentes y condicionan su acumulación en las plantas. El objetivo de esta investigación fue evaluar el efecto sinérgico en la acumulación simultánea de Pb y Cr (VI) en berro. Se utilizó un sistema cerrado y un humedal artificial para evaluar el comportamiento de los metales en presencia de berro, cuantificando al final de cada experimento la concentración acumulada en tallos, hoja y raíz. La mayor concentración de ambos metales fue en raíz (Pb > Cr). Al incrementarse la presencia de Cr (VI) en solución, la planta absorbe más metal, y en combinación con Pb el índice de tolerancia se aumenta y el factor de translocación disminuye. Dentro del humedal construido el porcentaje de remoción de Pb y Cr total fue del >99.9% (100 mg L-1) y 95% (28.5 mg L-1), respectivamente. Los resultados obtenidos indican que existen interacciones ambientales, físicas y químicas que determinan la capacidad de bioacumulación en el berro, de los metales evaluados.ABSTRACTHeavy metal pollution has increased over the years due to its different applications. Different plant species have been evaluated to bioaccumulate heavy metals; watercress is a species with phytoremediation capacity. However, there is little information on the synergy that occurs when two metals in the medium are present and condition their accumulation in plants. The objective of this research was to evaluate the synergistic effect on the simultaneous accumulation of Pb and Cr (VI) in watercress. We used a batch system and an artificial wetland to evaluate the behavior of metals in the presence of watercress, quantifying at the end of each experiment the cumulative concentration in stems, leaf, and root. The highest concentration of both metals occurred in the root section (Pb> Cr). As the presence of Cr (VI) in solution increases, the plant absorbs more metal, and combination with Pb the tolerance index is increased and the translocation factor decreases. Within the constructed wetland the percentage of total Pb and Cr removal was >99.9 % (100 mg L-1) and 95% (28.5 mg L-1) respectively. The results show the presence of effects of environmental, physical and chemical interactions that determine the capacity of bioaccumulation of the metals evaluated in watercress.

“…Inside plants, as arsenic speciation analysis showed, as can affect growth and productivity due to a plethora of morphological, physiological, biochemical, and molecular alterations (Abbas et al 2018 ). Due to the ease of arsenic accumulation in plants its toxicity and plant tolerance for this element, several speciation studies were carried out in: Acer platanoides (Budzyńska et al 2018 ), Pteris vittata (Wang et al 2002 ) radish ( Raphanus sativus L.) (Tlustos et al 2002 ), bean ( Phaseolus vulgaris ) (Sukanya et al 2018 ), Elodea canadensis (Picco et al 2019 ), herbs ( Mentha x piperita , Matricaria recutita (L.) Rauschert , Melissa officinalis L. and Salvia officinalis L.) (Jabłońska-Czapla et al 2019 ). Unfortunately, there is little research in the world literature on the arsenic speciation in nettles ( Urtica dioica L.) (Bergqvist and Greger 2012 ), goldenrod ( Solidago virgaurea L. ), reeds ( Phragmites communis L.) (Tremlova et al 2016 ).…”

The impact of water and bottom sediment pollution of a river subjected to a strong industrial anthropogenic pressure of metal(loid) (including arsenic and its species) accumulation in riverbank plants such as Solidago virgaurea L., Phragmites L. and Urtica dioica L. was investigated. The high-performance liquid chromatography-inductively coupled plasma-mass spectrometry (HPLC-ICP-MS) technique was used to study organic and inorganic arsenic species in selected plants and their response to heavy metal and arsenic contamination. The modified BCR extraction results showed that arsenic was mainly bound to the mobile reducible and organic-sulfide fractions in the Kłodnica River bottom sediments. Research has shown that the bottom sediments of the Kłodnica River are contaminated with metals, including Pb, Zn, Ni, As, and among arsenic species, the As(V) form dominated quantitatively, with its highest concentration being 49.3 mg kg−1 and the organic species occurred extremely rarely. The highest concentration of arsenic, among the tested plants, occurred in Phragmites communis L. The evaluation of the bottom sediment pollution was performed using Sb/As factor, geoaccumulation index (Igeo), enrichment factor (EF) and pollution load index (PLI). The ability of the plant to assimilate metals from the substrate was studied by calculation of the bioaccumulation factor (BAF). Values of the Igeo change in a wide range from class 1 (uncontaminated to moderately polluted for Cu and Zn) at the first sampling point, to 5 (highly to extremely polluted for Ba and Fe) at the K4 sampling point. The Igeo results show an increase in the contamination with elements toward the runoff of the Kłodnica River.
