“…The main bioaccessible As species in rice grain was inorganic As (e.g., As 3+ and As 5+ ). 70 The application of Se 0 NMs and ions significantly decreased the inorganic As to total As ratio by 13.7 and 9.8%, respectively (Figure 6B). The decreased inorganic As to total As ratio with Se amendment could be attributed to the enhanced reducing protein (e.g., GSH) content, increasing the reduction of As and then promoting As methylation in rice.…”

“…The bioaccessibility of As in the gastric phase was significantly decreased by 20.9 and 23.9% with Se 0 NMs and Se ion treatments, respectively. The main bioaccessible As species in rice grain was inorganic As (e.g., As 3+ and As 5+ ) . The application of Se 0 NMs and ions significantly decreased the inorganic As to total As ratio by 13.7 and 9.8%, respectively (Figure B).…”

In the current work, the foliar application of selenium nanomaterials (Se 0 NMs) suppressed sheath blight in rice (Oryza sativa). The beneficial effects were nanoscale specific and concentration dependent. Specifically, foliar amendment of 5 mg/L Se 0 NMs decreased the disease severity by 68.8% in Rhizoctonia solani-infected rice; this level of control was 1.57-and 2.20-fold greater than that of the Se ions with equivalent Se mass and a commercially available pesticide (Thifluzamide). Mechanistically, (1) the controlled release ability of Se 0 NMs enabled a wider safe concentration range and greater bioavailability to Se 0 NMs, and (2) transcriptomic and metabolomic analyses demonstrated that Se 0 NMs simultaneously promoted the salicylic acid-and jasmonic-aciddependent acquired disease resistance pathways, antioxidative system, and flavonoid biosynthesis. Additionally, Se 0 NMs improved rice yield by 31.1%, increased the nutritional quality by 6.4−7.2%, enhanced organic Se content by 44.8%, and decreased arsenic and cadmium contents by 38.7 and 42.1%, respectively, in grains as compared with infected controls. Human simulated gastrointestinal tract model results showed that the application of Se 0 NMs enhanced the bioaccessibility of Se in grains by 22.0% and decreased the bioaccessibility of As and Cd in grains by 20.3 and 13.4%, respectively. These findings demonstrate that Se 0 NMs can serve as an effective and sustainable strategy to increase food quality and security.

“…Mean As concentrations were higher than other heavy metals in rice. The increased transfer of As from soil to grain has resulted in rice exhibiting higher levels of As absorption than other metals, according to previous studies 16,17 . Additionally, because it is a staple food, humans consume harmful, inorganic As from rice 17 .…”

Heavy metal (HM) pollution has long been a significant source of environmental deterioration and a problem for the safety of food. Iraqis prefer rice over any other food, and since heavy metals have a direct impact on health, their traces in rice have drawn particular attention. Before cooking rice, it is usual in Iraq to wash and soak it. Some 55 varieties of imported and local rice were sampled from Erbil city markets in 2022 with the aim of determining the concentration of As, Cd, Cr, Ni and Pb before and after soaking. Standard procedure of acid digestions was applied on the raw and soaked samples. The solutions were analyzed using ICPE-9820 Shimadzu. The mean concentrations of As, Cd, Cr, Ni and Pb (in mg/kg) in the rice samples before soaking was 0.655, 0.170, 0.160, 0.387, 0.489, respectively and after soaking 0.421, 0.109, 0.115, 0.124 and 0.336, respectively. The concentration of As and Pb was found to be beyond the optimum level of 0.2 mg/kg codex standards for rice; whereas Cd and Cr were within the proposed level of codex standards. Moreover, local rice showed higher concentration of (Cd and Cr), whereas (AS and Pb) concentration in imported rice was higher. Further, results validated that rice soaking can decrease levels of As, Cd, Cr, Ni and Pb (32.5%, 40.2%, 27.9%, 61.6% and 31.3%, respectively). These findings suggest that soaking as a kitchen practice has efficiency to evaporate metals and has a great influence on the reduction of toxic heavy metals and thus reduces exposure to toxic metals in rice

“…Rice is the cereal that contains the most arsenic, compared to other foods, because it grows in a flooded environment with anaerobic conditions [106,107]. Rice is considered the leading food in the diet of many consumers, especially in Asian countries [63,106,108,109].…”

This paper reviews the arsenic in the environment. Arsenic contamination is currently one of the leading environmental problems worldwide. The arsenic (As) cycle is the subject of this article because As is an element with a significant impact on living beings and because of its interrelation with other biogeochemical cycles. The biogeochemical cycle of As is closed, so this trace element returns to sediments where it can be changed in its chemical state by micro-organisms present in soils. In addition, some minerals contribute to the sequestration and retention of As. This element interferes with other critical biogeochemical cycles such as sulfur, phosphorus, iron, manganese, and antimony. Another factor to consider is determining the content and interference of organic matter in the soil, as it forms very stable compounds with As. On the other hand, in aquatic environmental conditions, with a high concentration of organic matter and anaerobiosis, a reducing environment is created that facilitates the mobilization of As in the sediments.
