“…Almost 60% of the wheat produced globally is consumed as food [8], and wheat demand is globally expected to rise by an estimated 70% in the next few decades (2020-2050) as the human population increases and rising income levels increase household consumption [9]. In developing countries, various farmers use wastewater for irrigating crops, such as wheat, due to the fact of water shortages, thus Cd accumulation is increased in wheat grains [3]. Many studies have indicated that high Cd content in wheat is accumulated through the roots, and Cd may translocate to the shoot and grains [10].…”

Cadmium is a toxic heavy metal that may be detected in soils and plants. Wheat, as a food consumed by 60% of the world’s population, may uptake a high quantity of Cd through its roots and translocate Cd to the shoots and grains thus posing risks to human health. Therefore, we tried to explore the journey of Cd in wheat via a review of several papers. Cadmium may reach the root cells by some transporters (such as zinc-regulated transporter/iron-regulated transporter-like protein, low-affinity calcium transporters, and natural resistance-associated macrophages), and some cation channels or Cd chelates via yellow stripe 1-like proteins. In addition, some of the effective factors regarding Cd uptake into wheat, such as pH, organic matter, cation exchange capacity (CEC), Fe and Mn oxide content, and soil texture (clay content), were investigated in this paper. Increasing Fe and Mn oxide content and clay minerals may decrease the Cd uptake by plants, whereas reducing pH and CEC may increase it. In addition, the feasibility of methods to diminish Cd accumulation in wheat was studied. Amongst agronomic approaches for decreasing the uptake of Cd by wheat, using organic amendments is most effective. Using biochar might reduce the Cd accumulation in wheat grains by up to 97.8%.

Enmiendas orgánicas en la inmovilización de cadmio en suelos agrícolas contaminados: una revisión

El presente artículo es una revisión sobre el uso de las enmiendas orgánicas en la inmovilidad del cadmio en suelos agrícolas. El cadmio (Cd), se ha convertido en un problema global desde la industrialización y la implementación de prácticas agrícolas intensivas. En la actualidad, sigue siendo un problema ambiental omnipresente ya que es un metal altamente tóxico que persiste en el suelo por largos periodos debido a su mínima pérdida microbiana y química. Actualmente, existe conciencia pública sobre las implicaciones de los suelos agrícolas contaminados con cadmio y por ello ha aumentado el interés en desarrollar y/o aplicar técnicas rentables, amigables y respetuosas con el ambiente como la inmovilización in situ utilizando enmiendas orgánicas. Se concluye que las enmiendas orgánicas tienen el valor potencial para reducir la captación de Cd por las plantas y mejorar la inmovilización por procesos de adsorción, intercambio iónico, complejación y precipitación.

The accumulation of heavy metals in soil and plant tissue is a serious concern since it impacts both soil quality and food safety. This study evaluated the accumulation of heavy metals and the food quality of lettuce as a result of the application of chemical fertilizer (CF) and bioslurry (BS). The treatments were CF (158 kg ha−1 NPS and 200 kg ha−1 urea), BS (5 ton ha−1), and control with no fertilizer, laid out in a randomized complete block design with three replications. Soil samples were analyzed for their physico‐chemical characteristics. The concentrations of 10 heavy metals (As, Pb, Zn, Cd, Cu, Ni, Co, Fe, Mn, and Cr) in the agricultural soil, bioslurry, and lettuce tissue were determined. Both the BS and CF reduced the concentrations of most heavy metals in the agricultural soil, particularly As, Pb, and Cd. Only the mean concentration of Cd in the agricultural soils exceeded the threshold level set by WHO/FAO (2011) for agricultural soils. Similarly, the concentration of As, Pb, and Cd in lettuce tissue grown in BS‐treated soils and the concentration of As in agricultural soils surpassed the limit set for vegetables. Given the toxicities of As, Cd, and Pb, as well as the effect on food safety, human health, and the environment, it is unsafe to cultivate lettuce using either the agricultural soil or BS in the study area.
