“…Monferrán et al (2012) investigated chromium accumulation in Potamogeton pusillus for concentrations up to 38.5 mg L -1 Cr (VI) and reported decreasing BCF values from 535 to 200 with increasing concentrations. BCF values > 1000 using different species have only been reported at exposure concentrations of ≤ 1 mg L -1 (Arora et al 2006;Norouznia and Hamidian 2014;Newete et al 2016;Romanova et al 2016;Victor et al 2016;Eid et al 2020;Al-Abbawy et al 2021;Singh et al 2022). Odjegba and Fasidi (2007) found BCF > 1000 in Eichhornia for a Cr (VI) concentration of 15 mg L -1 after 21 days in experimental exposures, implying that a long exposure period at low to moderate levels of contamination may lead to greater accumulation in plant tissue.…”

This study examined the potential of the aquatic macrophyte Eichhornia crassipes for bioaccumulating hexavalent chromium and its effects on the plant's morphology. The macrophytes were exposed to different concentrations of Cr (VI) (0 -100 mg L -1 ) in 20% full-strength Hoagland nutrient solution for ten days. Changes in the Cr (VI) concentrations were measured in the media and in specific plant tissues, i.e., roots, shoot, and leaves. The bioconcentration factor (BCF) in all plant parts and the translocation factor (TF) within plant tissues were calculated twice during the experiment. Results demonstrated that E. crassipes accumulated high concentrations of Cr (VI) in all plant tissues examined in a dose-specific manner. High BCF was observed in the plant roots for concentrations up to 60 mg L -1 , after which accumulation in shoots and leaves were greater than roots. The results from E. crassipes survivorship indicated that 40 mg L -1 is the threshold concentration for their survival under Cr (VI) stress. Morphological changes in the plants were examined by monitoring the change in the number of leaves and plant height under varying Cr (VI) concentrations. Impeded growth was observed due to increasing Cr (VI) concentration with maximum growth in the control group with no Cr (VI). Evapotranspiration losses were monitored and found to be minimal in experimental groups with high concentrations, displaying a negative correlation with Cr (VI) contamination. Physico-chemical parameters including pH, Electrical Conductivity, Oxidation Reduction Potential, and colour were also found to be significantly correlated with Cr (VI) concentration and time. The results demonstrated significant Cr (VI) accumulation in E. crassipes as well as noticeable morphological changes, making E. crassipes a suitable organism for biomonitoring and remediating Cr-contaminated sites over a relatively short time-period.

“…Furthermore, the samples were dried in a hot air oven (50−55 • C) for four days and stored. To analyze As 0.5 g of plant tissue was again oven-dried (70 • C for two days) and digested in 3 mL of HNO 3 and H 2 O 2 USEPA Method 3050B (Singh et al, 2022). After digestion, 15 mL of DDW was added, and the solution was passed through Whatman ashless filter paper (Grade 42 circles, diameter 125 mm).…”

This study investigated the concentrations of arsenic (As) in soil and plant biomass from the Barak Valley in South Assam, India. Soil samples showed concentrations ranging from 6.06 ± 0.84 mg/kg to 18.61 ± 1.52 mg/kg, with an average of 10.60 ± 3.15 mg/kg, 41.67% of the sample exceeding uncontaminated ranges (0.1–10 mg/kg). Ecological risk assessments such as contamination factors, pollutant load index, geo‐accumulation index, and anthropogenicity identified varying contamination levels across sampling points. A total of 24 plant species were collected, ferns (two species), shrubs (five species), grass (six species), and herb (11 species). The concentration of As in different plants types decreased in the order of fern (393.45 ± 159.63 mg/kg) > shrub (20.48 ± 7.25 mg/kg) > herb (17.92 ± 13.75 mg/kg) > grass (14.98 ± 13.80 mg/kg). Plant species, namely Pityrogramma calomelanos, Christella dentata, Mimosa pudica, Chromolaena odorata, Leucas aspera, Persicaria decipiens, Melastoma malabathricum, and Clerodendrum infortunatum, accumulated higher concentrations of As in their above‐ground parts compared to roots and were categorized as tolerant accumulators (TF > 1). By incorporating these plant species into phytoextraction strategies, the region can benefit from their unique properties and abilities to effectively remediate arsenic‐contaminated sites, ultimately improving the affected areas' environmental and human health conditions.

oil and water supply us with the essentials of life, including clean water, healthy edible foods, feed, fiber, shelter, and fuel. Soil also serves as a repository for soil and water are both central components of human culture. The close interactions between soil, water, plants and humans are very important for human health and well-being. This is a call for the submission of original manuscripts on this nexus that uses photographs to communicate how the nexus functions and its importance to humanity. This approach is based on a more photos, less words paradigm to create narrative photographic studies. More studies are needed that focus on different aspects of the soil-water-plant-human (SWPH) nexus. Any combination of the components of the SWPH nexus that includes the human component (e.g., soilwater-human, soil-plant-human, etc.) is welcome as part of this special section. The ultimate goal of these articles is to add to knowledge of the SWPH nexus in a way that incorporates art and culture into our scientific understanding of some of today's major global challenges.
