Arsenic(V) and vanadium(V) fractionation after its incorporation into a sandy loam soil from Pampas region, Argentina.

Arsenic is a well-known toxic substance, widely distributed, whereas vanadium is a pollutant of emerging interest. Both have been found to correlate positively in groundwaters, thus concern arises on the effect of these pollutants on crops, if such waters are used for irrigation. We conducted a study on the effect of aging with a typical crop soil mimicking soils initially irrigated with water containing As and V.

Trace elements in Alaska's ice seals in the 2000s and 2010s.

Ringed (Pusa hispida), bearded (Erignathus barbatus), spotted (Phoca largha), and ribbon (Histriophoca fasciata) seals are ice-associated seals that are important subsistence resources for coastal Alaska Native people. These seals are also mid- to upper trophic level Arctic predators and primary prey of polar bears (Ursus maritimus). We analyzed concentrations of 19 trace elements in seal liver, kidney, muscle, and blubber, including arsenic, cadmium, lead, mercury, and vanadium due to their potential toxicity.

Fertilization of potentially toxic element-contaminated soils remediated with reusable biochar pellets using rice straw, pig manure and their derived biochar.

Potentially toxic elements (PTEs) are widespread pollutants in agricultural fields, presenting significant challenges to the maintenance of soil ecological functions while simultaneously reducing their concentrations. This study detailed the development of a high-strength reusable silicate magnetic composite biochar sphere (SMBCS) characterized by superior magnetic and adsorption properties, synthesized from natural minerals and biochar. The application of SMBCS over three consecutive remediation cycles led to reductions in cadmium (Cd), lead (Pb), and arsenic (As) concentrations in soil by 28.

The Role of the cGAS/STING Pathway in Arsenic-Induced Neurotoxicity: Insights from the Crosstalk Between Astrocytes and Neurons.

Arsenic is a detrimental environmental toxicant linked to neurological damage; however, the mechanisms involved remain incompletely understood. Chronic proinflammatory responses are thought to play a central role in arsenic-induced neurotoxicity. Astrocytes, which are the predominant glial cells in the central nervous system (CNS), release significant amounts of proinflammatory cytokines upon overactivation.

The advent of all-trans retinoic acid (ATRA) and arsenic trioxide (ATO) has revolutionized the treatment of acute promyelocytic leukemia (APL), resulting in excellent rates of remission and long-term survival. However, real-world outcomes often fall short of those observed in clinical trials due to various factors related to patient demographics and clinical practices. This review examines APL treatment outcomes in real-world settings and highlights the phenomenon of APL clusters.

Host-microbiota interplay in arsenic metabolism: Implications on host glucose homeostasis.

Arsenic (As), a naturally occurring element with unique properties, has been recognized as the largest mass poisoning in the world by the World Health Organization (WHO). Approximately 200 million people worldwide are exposed to toxic levels of arsenic due to natural and anthropogenic activities. This widespread exposure necessitates a deeper understanding of microbe-arsenic interactions and their potential influence on host exposure and health risks.

Biomonitoring of toxic metal exposure in New Jersey adults in 2015-2018.

This study explores the potential of a convenience sample-based probing approach as a cost-effective alternative for state-level biomonitoring surveillance, addressing the logistical and practical challenges when applying comprehensive probability-based population studies at a state-level. The New Jersey Department of Health (NJDOH) conducted a large-scale biomonitoring study using 2988 blood samples and 1007 urine samples collected from clinical laboratories and blood banks statewide from 2015 to 2018 to characterize toxic metal exposure patterns and trends. The resulting data were analyzed to identify contributing factors and compared to concurrent U.

Helicobacter pylori promotes intestinal flora imbalance and hepatic metabolic disorders under arsenic stress.

Environmental arsenic contamination is a serious issue that cannot be ignored, since arsenic levels in drinking water frequently exceed safety standards, and there is an increased prevalence of Helicobacter pylori (H. pylori) infection. This results in an increasing population at risk of simultaneous exposure to both harmful agents, yet whether a synergistic interaction exists between them remains unclear.

Pavlovian-Type Learning in Environmental Bacteria: Regulation of Herbicide Resistance by Arsenic in Pseudomonas putida.

The canonical arsRBC genes of the ars1 operon in Pseudomonas putida KT2440, which confer tolerance to arsenate and arsenite, are followed by a series of additional ORFs culminating in phoN1. The phoN1 gene encodes an acetyltransferase that imparts resistance to the glutamine synthetase inhibitor herbicide phosphinothricin (PPT). The co-expression of phoN1 and ars genes in response to environmental arsenic, along with the physiological effects, was analysed through transcriptomics of cells exposed to the oxyanion and phenotypic characterization of P.
