Spatiotemporal distribution of oxidative potential in PM2.5 and its key components across six Chinese cities J. Hazard. Mater. (IF 12.2) Pub Date : 2024-07-06 Jin Ye, Hao Hu, Zhongming Bu, Jianping Cao, Wei Liu, Chunxiao Su, Xinke Wang, Yinping Zhang, Haidong Kan, Zhen Ding, Hua Qian, Shijie Cao, Cong Liu
Increasing evidence has supported that oxidative potential (OP) serves as a crucial indicator of health risk of exposure to PM over mass concentration. However, there is a lack of comparative studies across multiple cities, particularly on a fine temporal scale. In this study, we aim to investigate daily variation of ambient PM OP through simultaneous samplings in six Chinese cities for one year. Results

3MTox: A motif-level graph-based multi-view chemical language model for toxicity identification with deep interpretation J. Hazard. Mater. (IF 12.2) Pub Date : 2024-07-06 Yingying Zhu, Yanhong Zhang, Xinze Li, Ling Wang
Toxicity identification plays a key role in maintaining human health, as it can alert humans to the potential hazards caused by long-term exposure to a wide variety of chemical compounds. Experimental methods for determining toxicity are time-consuming, and costly, while computational methods offer an alternative for the early identification of toxicity. For example, some classical ML and DL methods

Preparation of dual recognition adsorbents based on molecularly imprinted polymers and aptamer for highly sensitive recognition and enrichment of ochratoxin A J. Hazard. Mater. (IF 12.2) Pub Date : 2024-07-06 Lingjun Geng, Jingjing Liu, Wenbin Zhang, Haifang Wang, Jingcheng Huang, Guangxian Wang, Mengjiao Hu, Haowei Dong, Jiashuai Sun, Mingxuan Fang, Yemin Guo, Xia Sun
In light of the significant risks that mycotoxins posed to public health and environmental safety, this research developed an adsorbent MIPs/Apt/AuNPs@ZIF-67 (MA-AZ) utilizing a dual-recognition approach combining molecularly imprinted polymers (MIPs) and aptamer (Apt). This innovative method enabled the effective and highly selective recognition and enrichment of ochratoxin A (OTA). ZIF-67 was utilized

Characteristics of radioactive aerosols during the pre-decommission phase of the experimental shielding reactor J. Hazard. Mater. (IF 12.2) Pub Date : 2024-07-05 Fei Zhou, Xiaotong Chen, Haisheng Liu, Xinchun Feng, Tao Ma, Zhenzhong Zhang
The decommissioning of nuclear reactors is a global concern, in part because of the generation of radioactive aerosols that can lead to internal radiation exposure. At present, radioactive aerosols generated during nuclear decommissioning have not been actively studied, and data collected from the actual decommissioning are limited. This paper presents a study of radioactive aerosols generated during

Efficient PFAS removal from contaminated soils through combined washing and adsorption in soil effluents J. Hazard. Mater. (IF 12.2) Pub Date : 2024-07-05 Muhammad Usman, Aaifa Chaudhary, Khalil Hanna
This study investigates soil washing as a viable strategy to remove poly- and perfluoroalkyl substances (PFAS) from contaminated soils using various washing agents including water, methanol, ethanol, and cyclodextrin ((2-Hydroxypropyl)-β-cyclodextrin HPCD)). Water was less effective (removing only 30 % of PFAS), especially for long-chain hydrophobic PFAS. Methanol (50 % v/v) or HPCD (10 mg g soil)

Label-free and ultrasensitive detection of environmental lead ions based on spatially localized DNA nanomachines driven by hyperbranched hybridization chain reaction J. Hazard. Mater. (IF 12.2) Pub Date : 2024-07-05 Xiao-Yu Li, Bo-Xi Zhou, Yu-Ling Xiao, Xin Liu, Yong-Qian Wang, Ming-Min Li, Jun-Ping Wang
A label-free fluorescent sensing strategy for the rapid and highly sensitive detection of Pb was developed by integrating Pb DNAzyme-specific cleavage activity and a tetrahedral DNA nanostructure (TDN)-enhanced hyperbranched hybridization chain reaction (hHCR). This strategy provides accelerated reaction rates because of the highly effective collision probability and enriched local concentrations from

Insights into in situ surface reconstruction in cobalt perovskite oxides for enhanced catalytic activity J. Hazard. Mater. (IF 12.2) Pub Date : 2024-07-05 Yanyu Jin, Hongjun Cheng, Qibao Wang, Xiaoqing Liu, Shengpeng Mo, Bin Zhou, Yue Peng, Yu Wang, Wenzhe Si, Junhua Li
An depth understanding of the fundamental interactions between surface termination and catalytic activity is crucial to prompt the properties of functional perovskite materials. The elastic energy due to size mismatch and electrostatic attraction of the charged Sr dopant by positively charged oxygen vacancies induced inert A-site surface enrichment rearrangement for perovskites. Lower temperatures

Co2+ coordination-assisted molecularly imprinted covalent organic framework for selective extraction of ochratoxin A J. Hazard. Mater. (IF 12.2) Pub Date : 2024-07-05 Li-Hong Su, Hai-Long Qian, Cheng Yang, Xiu-Ping Yan
Covalent organic frameworks (COFs) are attractive materials for sample pretreatment due to their tunable structures and functions. However, the precise recognition of contaminant in complex environmental matrices by COFs remains challenging owing to their insufficient specific active sites. Herein, we report Co coordination-assisted molecularly imprinted flexible COF (MI-COF@Co) for selective recognition
