“…Elements such as As, Ba, Be, Cd, Co, Cr, Cu, Li, Mn, Ni, Pb, Sb, Sr, Te, Th, Tl, U, and V are considered toxic, and their total concentration varied from 28.0 to 1,629 mg kg −1 . The concentration of the toxic elements (As, Cr, Cd, Zn, Pb, Ba and U) in the plants of Ambagarh Chowki was observed to be higher than those reported in other regions 21,41,42,43,44,45,46 .…”

Grains of rice, wheat, and maize are staple foods widely consumed for their mineral and nutritional values. However, these cereals can accumulate toxic elements from contaminated soils, posing health risks. This study investigates the bioaccumulation patterns of 52 minerals (including nutrients, heavy metals, and rare earth elements) accumulated over range 10249 to 58414 mg kg− 1 (dw) in various parts (grain, husk, straw, root) of these cereals grown in the heavily polluted region of Ambagarh Chowki, India. The results reveal rice exhibits a higher accumulation of toxic elements compared to wheat and maize grains, with the high-yield Sarna cultivar being the most susceptible. Across the rice plant, accumulation increased in the order: grain < husk < straw < root. Elements like P, K, Cu, and Zn showed the highest enrichment. Worryingly, most toxic elements like As, Pb, and Cd exceeded permissible limits across grains, straws, and husks. Health risk assessment indicates wheat and maize pose greater non-cancer and cancer risks than rice. Despite being grown in a highly contaminated region, the study identifies some rice cultivars like Naya 1010 and Sonam as relatively safer options due to the lower accumulation of toxic elements in the grains. This comprehensive analysis provides valuable insights into cereal safety and highlights the need for monitoring polluted areas to mitigate health hazards through judicious selection of crop varieties.

“…Identifying several As hyperaccumulator ferns, such as Pityrogramma calomelanos and Pteris vittata has significantly advanced the research in this area (Patel et al, 2023). Other than the fern, several plants species were also identified, such as Anthoxanthum odoratum, Plantago lanceolata, Achillea millefolium, Panicum maximum, Zea mays, and Pennisetum purpureum (Okoye et al, 2022;Tremlová et al, 2016).…”

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.

“…In the 40 years since the relation between arsenic (As) toxicity and groundwater extraction was first documented from the Holocene alluvial basin of West Bengal, India, we have become more aware that groundwater contamination with naturally occurring (geogenic) As poses a serious health threat of global proportions . With the aim of implementing effective and sustainable mitigation strategies, research into the occurrence and location of toxic As levels in drinking and irrigation water and in the food chain provided insight into all aspects of the As-contamination issue, including (a) geogenic As provenance in volcanic and metamorphic rocks, hydrothermal additions to groundwater and hot springs, and weathering of rocks in orogenic mountain belts, (b) its accumulation in sedimentary-basin aquifers, (c) the mobilization and transport of the contaminant into the groundwater, and (d) the associated health risks of sustained As ingestion for >200 million people around the world. , A wide range of potential As-mitigation measures have been proposed over the years, ranging from in situ chemical and biological oxidative processes for immobilizing As to subsequent filtration methods and social awareness programs for the affected population. − …”
