“…Lyophilized plant samples were ground and homogenized with a mortar and pestle. Samples were mineralized using Teflon tubes, as previously described in the literature ( Griboff et al., 2018 ; Bertrand et al., 2019 ). First, approximately 30 mg of sample were digested with 3 mL of HNO 3 (sub-boiling grade) and 0.5 mL of HCl (ultrapure), in closed Teflon tubes on heating plates set to 220 °C, during 8 h. Complete mineralized samples were quantitatively transferred to 10 mL volumetric flasks, completing the volume with HNO 3 2 %, followed by filtration using 0.45 μm filters.…”

Metals in the environment have been an increasing research topic over the past decade, since they can be found in both natural and drinking water, including irrigation of crops and edible plants with contaminated water. The aim of this study was to investigate the uptake of Cr by arugula ( Eruca sativa ) in a greenhouse experiment, simulating the open field irrigation conditions. We also evaluate the toxic effects of Cr on oxidative stress by measuring the antioxidant capacity and polyphenol profile in the plant. The study examines the irrigation of arugula, during 15 and 21 days, with four Cr (VI) concentrations, ranging from 0 (control) to 250 μg. L −1 . Arugula plants were able to accumulate Cr when irrigated during 15 and 21 days in all the Cr concentrations evaluated. The estimated daily intake (EDI) shows that the amount of Cr accumulated by arugula plants does not represent a threat to human health. Application of Cr levels induced some changes in content, profile and capacity of antioxidants depending on Cr concentration and time of exposure. Taking into account that E. sativa is consumed due to its polyphenol-related health benefits, the allowable Cr limits in irrigation water should be reviewed, in order to maximize health benefits associated with its consumption, and also to improve vegetable quality. Arugula is a valuable and nutritious food, that should not be excluded from a balanced diet. Chromium concentration in irrigation water as well as the speciation forms present in vegetables should be controlled.

“…This is reaffirmed by the current presence of clarithromycin (n.d.-0.145 µg L −1 ), not detected before (Valdés et al, 2014). Clarithromycin was quantified in a higher flow river of Córdoba province, the Ctalamochita River, at 0.008 µg L −1 (Bertrand et al, 2019).The Suquía River has been suffering a serious environmental quality degradation as a result of different anthropogenic uses and Córdoba WWTP impact, which has increased its deterioration (Pesce & Wunderlin, 2000, Wunderlin et al, 2001, Merlo et al, 2011, Amé & Pesce, 2015. This quality deterioration is also highlighted by antibiotic concentrations, originating from diffuse and point urban sources of pollution along Suquía River.…”

“…Potamogeton pusillus L. is a native macrophyte with totally submerged or oating leaves (heterophylly) with ecological importance in sub-tropical aquatic ecosystems, present in wild and urban habitats in Argentina (Monferrán et al 2009). The use of this aquatic plant has been investigated for the monitoring and remediation of water bodies polluted with heavy metals like Cu 2+ , Cr + 6 , As + 3 , As + 5 , and Hg (Monferrán et al 2009(Monferrán et al , 2012Harguinteguy et al 2016;Griboff et al 2018;Bertrand et al 2019). Local macrophyte species with an elevated biomass production rate, such as P. pusillus, enable more sustainable and economically viable phytoremediation strategies, especially in areas where communities have limited nancial resources.…”

Under the present investigation, the submerged plant Potamogeton pusillus has been tested for the removal of lead (Pb) and cadmium (Cd). P. pusillus removal e ciency and accumulation capacity were examined in separated Pb and Cd solutions, at 0.5, 1.0, and 2 mg L -1 , and in solutions where both metals were present at the same concentration (0.5, 1.0, and 2 mg L -1 ), under laboratory conditions for 3, 7, and 10 days. Also, we examined the removal e ciency and accumulation capacity when a set of plants were exposed to 0.5 mg L -1 of Pb (or Cd) and increasing concentrations (0.5, 1, and 2 mg L -1 ) of Cd (or Pb) for 10 days. The effect of Cd and Pb was assessed by measuring changes in the chlorophylls, carotenoids, and malondialdehyde contents. Results showed that P. pusillus could accumulate Cd and Pb from individual solutions. Roots and leaves accumulated the highest amount of Cd and Pb followed by the stems. Some phytotoxic effects were observed, especially at individual Cd exposures, but these effects were not observed in the two-metal system. The removal and accumulation of Pb by P. pusillus were signi cantly enhanced in the presence of Cd under certain conditions, presenting a good alternative for the removal of these metals from polluted aquifers. To the extent of our knowledge, this is the rst report on both enhanced phytoextraction of Pb in the presence of Cd and bioaccumulation of these heavy metals by P. pusillus.
