Summary: This research conducted a sampling survey of heavy metals contents in selenium-rich rice, which revealed the association between selenium and cadmium accumulation in rice and soil. A pot experiment confirmed the significant association between the contents of selenium and cadmium in rice grain and the concentrations of selenium and heavy metals in soil. Transcriptome analysis indicated the up-regulation of transporter-coding genes may promote the absorption of selenium and cadmium. The up-regulation of antioxidant-coding genes and cadmium chelator transporter coding-genes was observed to reduce the toxicity of cadmium. Moreover, the up-regulation of key genes of the ascorbic acid-glutathione metabolic pathway were responsible for the association between selenium and cadmium in Se-rich rice.

Summary: Co-contamination of soil by microplastics (MP) and arsenic (As) poses a severe threat to agricultural productivity. The impact of this joint pollution on crop growth was assessed by investigating the transcriptomic and phenotypic patterns of rice. The results showed that MP had less impact on rice growth compared to As, but the MP-As mixture decreased rice's aboveground biomass and altered the distribution of As in rice tissues. Transcriptomic analysis revealed that the joint application of MP and As produced a synergistic effect on crucial metabolic processes and reprogrammed the expression of hub genes involved in photosynthesis and defense. These findings suggest that MP aggravates the As-induced toxicity in rice plants and may affect the crop's adaptation to other abiotic field environments.

Summary: This study conducted a survey in the Mekong Delta and found no relationship between rice arsenic concentration and speciation with soil levels, but a strong correlation was observed between rice and groundwater arsenic concentrations. The study hypothesizes that surficial sediments with high concentrations of arsenic may serve as sources of arsenic to downgradient shallow aquifers.

Summary: The addition of silkworm excrement (SE) to soil can reduce the concentrations of cadmium (Cd) and arsenic (As) in rice grains. This is achieved by increasing soil pH, electrical conductivity, and organic matter content (for Cd) and increasing the abundance of microorganisms involved in As methylation (for Cd and As). Overall, this study provides a new approach to improve the utilization of agricultural waste resources and ensure the safety of food production.

Summary: Arsenic is a hazardous metalloid in nature due to its high solubility in water, with silicon being able to reduce its uptake in rice. The study looked at the effects of different arsenic and silicon levels on dry weight, protein content, and concentrations of arsenic and silicon in two different rice genotypes. The presence of silicon increased dry weight and protein content while decreasing arsenic concentration in both roots and shoots, demonstrating the resistance of the transgenic genotype to arsenic.

Summary: The interaction between selenium and sulfur in plants and soils is important to study as it affects selenium nutrition and toxicity, crop composition and production, and the risk of toxicity to humans and animals. This study evaluated the impact of selenium exposure on rice plants grown under different sulfur supplies at different growth stages. The results showed that sulfate supply alleviated selenate toxicity, while soil clay content influenced selenate availability and adsorption capacity.

Summary: This study investigated the effects of different doses of polystyrene (PS) and polyvinyl chloride (PVC) microplastics (MPs) on the growth, ionic homeostasis, and antioxidant metabolism of rice plants. Results showed that PVC-MPs accumulation had a more devastating impact on rice growth and metabolism compared to PS-MPs, with D-3 and D-6 being the most harmful treatments. Further research is recommended to fully understand the influence of different sized MPs on food safety.

Summary: Increasing temperature favored the release of total As, arsenite (As(III)) and arsenate (As(V)) into soil pore-water, leading to higher As(III) accumulation in rice grains at warmer treatment. The study also found that Xanthomonadales order, Alcaligenaceae family, and arsC gene were enriched in rhizosphere soils at 33 degrees C, contributing to enhanced As(V) reductive dissolution into soil pore-water. Overall, the research provides insights on how warmer temperatures may exacerbate As accumulation in rice grains in the future.

Summary: To avoid drug resistance, different sulfonamides (SAs) were used alternately in animal husbandry. Therefore, developing simple and high-throughput methods for detecting multiple or groups of SAs is crucial for rapid screening of total SAs residues in foods. In this study, a sensitive and efficient immunosensor using AuNBPs and broad-specificity anti-SAs antibody was developed for the visual screening/semi-quantitative detection of 6 different SAs. The immunosensor showed excellent specificity, low visual detection limit, and can be applied in milk with high recovery rate.

Summary: This study systematically investigates luminescent molybdenum disulfide quantum dots (MoS2 QDs) for the first time and finds that the reported blue fluorescence of MoS2 QDs mainly comes from co-existing carbon-based dots rather than MoS2 itself. Additionally, the band gap of MoS2 is independent of its lateral size, making it impossible to obtain luminescent MoS2 QDs by reducing the lateral size.
