    Evaluation of the Effect of Salicylic Acid and Brassinosteroid on Some Physiological Traits and Arsenic Accumulation in Spinach under Arsenic Stress Conditions by K. Maghsoudi, E. Ashrafi Dehkordi, S. M. Mazloomi

    Published 2024-04-01
    “…With the aim of evaluating the effects of salicylic acid and brassinosteroid application on some physiological traits and arsenic accumulation in spinach under arsenic stress conditions, an experiment was conducted in a factorial experiment in the form of a randomized complete block design with four replications in the year 2022 in the Nutrition Research Center, Department of Food Hygiene and Quality Control, School of Nutrition and Food Sciences, Shiraz University of Medical Sciences, Iran. …”

    Claroideglomus etunicatum enhances Pteris vittata L. arsenic resistance and accumulation by mediating the rapid reduction and transport of arsenic in roots by Guofei Pan, YueZhen Xu, WeiZhen Li, Linyan Zan, Xueli Wang

    Published 2024-11-01
    “…Arbuscular mycorrhizal fungi (AMF) have been widely shown to significantly promote the growth and recovery of Pteris vittata L. growth and repair under arsenic stress; however, little is known about the molecular mechanisms by which AMF mediate the efficient uptake of arsenic in this species. …”

    Amphibian tolerance to arsenic: microbiome-mediated insights by Isabella Ferreira Cordeiro, Camila Gracyelle de Carvalho Lemes, Angélica Bianchini Sanchez, Ana Karla da Silva, Camila Henriques de Paula, Rosilene Cristina de Matos, Dilson Fagundes Ribeiro, Jéssica Pereira de Matos, Camila Carrião Machado Garcia, Marina Beirão, C. Guilherme Becker, Maria Rita Silvério Pires, Leandro Marcio Moreira

    Published 2024-05-01
    “…At lower arsenic concentrations (1 and 5 mM As3+), we found a significantly higher number of bacterial isolates tolerant to arsenic from amphibians sampled at an arsenic contaminated region (TES) than from amphibians sampled at an arsenic free region (JN). …”

    Migration and enrichment of arsenic during coal washing by Xie Weiwei, Zhou Lingmei, Zheng Hao

    Published 2022-12-01
    “…During the processing and utilization of coal resources, some heavy metal elements will be enriched in the environment, which is harmful to the environment and the human body.In this study, low-ash, high-sulfur coal samples and high-ash, low-sulfur coal samples from Inner Mongolia were selected for float-and-sink test and flotation, and were analyzed by inductively coupled plasma mass spectrometer (ICP-MS), X-ray diffraction analysis, X-ray fluorescence analysis, and scanning electron microscopy energy spectrum analysis.Infrared spectroscopy and other test methods were used to study the occurrence form of heavy metal arsenic in coal and its migration and enrichment law during the processing.The experimental results show that the two coal samples demonstrates the highest proportion of arsenic present in the aluminosilicate bound state, reaching more than 50 %, but the types of aluminosilicate minerals are not the same, and the occurrence of arsenic has obvious differences.Flotation results show that arsenic in low-ash and high-sulfur coal sample is mainly associated with minerals and concentrated in the denser part, while high-ash and low-sulfur coal is mainly concentrated in the part with lower density and higher organic content; there are also differences in the migration law of arsenic in flotation.During the flotation, the arsenic in low-ash and high-sulfur coal migrates to the tailings, while the arsenic in the high-ash and low-sulfur coal migrates to the clean coal.The above findings show that it is feasible to remove arsenic from low-ash and high-sulfur coal sample by flotation but the effect is not so good for high-ash and low-sulfur coal sample, indicating that the removal of arsenic must consider the impact of coal type.…”
