Widespread pesticide use in agriculture is a major source of soil pollution, driving biodiversity loss and posing serious threads to human health. The recalcitrant nature of most of these pesticides demands for effective remediation strategies. In this study, we assess the ability of soil microbial fuel cell (SMFC) technology to bioremediate soil polluted by the model pesticide atrazine. To elucidate

Gut microbiome and antibiotic resistance genes in plateau model animal (Ochotona curzoniae) exhibit a relative stability under cold stress J. Hazard. Mater. (IF 12.2) Pub Date : 2024-08-09 Xianxian Mu, Shunqin Shi, Xueqian Hu, Xueying Gan, Qian Han, Qiaoling Yu, Jiapeng Qu, Huan Li
Antibiotic resistance genes (ARGs) carried by gut pathogens may pose a threat to the host and ecological environment. However, few studies focus on the effects of cold stress on intestinal bacteria and ARGs in plateau animals. Here, we used 16S rRNA gene sequencing and gene chip technique to explore the difference of gut microbes and ARGs in plateau pika under 4 °C and 25 °C. The results showed that

Ultrahigh humidity-resistance ppb-level formaldehyde sensing at room temperature induced by fluorinated dipole based "umbrella" and "bridge" J. Hazard. Mater. (IF 12.2) Pub Date : 2024-08-09 Sitao Lv, Liming Liu, Lanpeng Guo, Zhijian Mai, Honghao Chen, Chenxu Wang, Fengnan Wang, Hao Li, Yi-Kuen Lee, Ahmad M. Umar Siddiqui, Zichuan Yi, Guofu Zhou, Yao Wang
Formaldehyde (HCHO) is a major indoor pollutant that is extremely harmful to human health even at ppb-level. Meanwhile, ppb-level HCHO is also a potential disease marker in the exhalation of patients with respiratory diseases. Higher humidity resistance and lower practical limit of detection (pLOD) both have to be pursued for practical HCHO sensors. In this work, by assembling indium oxide (InO) and

Pesticide-induced transgenerational alterations of genome-wide DNA methylation patterns in the pancreas of Xenopus tropicalis correlate with metabolic phenotypes J. Hazard. Mater. (IF 12.2) Pub Date : 2024-08-09 Mauricio Roza, Andreas N.M. Eriksson, Sofie Svanholm, Cecilia Berg, Oskar Karlsson
The unsustainable use of manmade chemicals poses significant threats to biodiversity and human health. Emerging evidence highlights the potential of certain chemicals to cause transgenerational impacts on metabolic health. Here, we investigate male transmitted epigenetic transgenerational effects of the anti-androgenic herbicide linuron in the pancreas of frogs, and their association with metabolic

The quorum sensing SinI/SinR-TraI/TraR systems promote Pb stabilization by Ensifer adhaerens S24 in the Pb-polluted aquatic environment J. Hazard. Mater. (IF 12.2) Pub Date : 2024-08-09 Yanyan Ge, Qi Sheng, Lijing Sun, Linyan He, Xiafang Sheng
In this study, the Pb-resistant strain S24, which contains quorum sensing (QS) systems responsible for N-acyl homoserine lactone (AHL) production, was investigated for QS system-mediated Pb stabilization and the underlying mechanisms. Whole-genome sequence analysis revealed the QS SinI/R and TraI/R systems in strain S24. Subsequently, strains S24 and the S24∆, S24∆, S24∆, and S24∆- mutants were constructed
