Defluorination is essential to eliminate the antibiotic resistance and detrimental effects of florfenicol (C12H14Cl2FNO4S, FF), which achievable by sulfidated nanoscale zerovalent iron (S-nZVI), yet a comprehensive understanding mechanism lacking. Herein, we used experimental data density functional theory calculations demonstrate four dechlorination-promoted defluorination pathways FF, depending on S-nZVI or not. FF was defluorinated in rapid then slow but continuous manner, accompanying...
China aims to actively control the contamination of globally concerning per- and polyfluoroalkyl substances (PFASs). Evaluation current situation can provide a critical reference point for tracking effectiveness ongoing progress. Herein, we present first comprehensive assessment spatial variations 20 legacy 54 novel PFASs in Chinese background soils 2021. Novel were extensively detected 98.4% samples, with 21 species being reported, which greatly facilitated appointment diverse emission...
Abstract Per and poly-fluoroalkyl substances (PFAS) are ubiquitous in the environment have been detected tissues of wildlife humans. While new chemicals continually being added to PFAS category, information on mechanisms thresholds for adverse effects these novel contaminants often limited. To explore potential fishes caused by maternal exposure, five PFAS, PFBA, PFBS, GenX, PFOA, PFOS were deposited oocytes two salmonid species, Arctic char (Salvelinus alpinus) rainbow trout (Oncorhynchus...
Stormwater pipeline is an essential pathway to transfer stormwater runoff into nearby receiving water bodies. Understanding the composition, co-occurrence patterns, and function of microbial communities in sediments can help provide management control strategies for pollution safeguard safety ecological health urban environment. This study employs 16S rRNA gene amplicon sequencing probe a highly urbanized area Guangzhou, China. Results show that sediment bacterial community rich Listeria,...
In-source fragmentation (ISF) was inevitable during electrospray ionization (ESI) of per- and polyfluoroalkyl substances (PFAS) when analyzed by liquid chromatography coupled with mass spectrometry (LC-MS), resulting in reduced response molecular ions misannotation MS features. Herein, we 82 PFAS across 12 classes to systematically identify the structures ISF potentials reveal pathways. We found up 100% for 38 six classes, which all contain carboxylate (CO
Abstract Arctic warming associated with global climate change poses a significant threat to populations of wildlife in the Arctic. Since lipids play vital role adaptation organisms variations temperature, high‐resolution mass‐spectrometry‐based lipidomics can provide insights into adaptive responses warmer environment and help illustrate potential novel roles process thermal adaption. In this study, we studied an ecologically economically important species—Arctic char ( Salvelinus alpinus...
Abstract Aqueous film–forming foams (AFFFs) are used in firefighting and sources of per‐ polyfluoroalkyl substances (PFAS) to the environment through surface runoff groundwater contamination at defense transportation sites. Little is known regarding toxicity bioaccumulation newer AFFF formulations containing novel PFAS. To mimic maternal transfer PFAS, prefertilization rainbow trout eggs were exposed three PFAS using methodologies. Batches unfertilized oocytes for 3 h 0, 0.01, 0.1, 1, or 10...

With the popularisation of modern information technology, use Internet in people's daily lives has gradually become widespread. Which make education more and diversified. Online classes have prevalent, online ushered wide application network technology field education, peak development. The traditional offline teaching mode needs to be carried out at a specific time as well place is mainly based on knowledge transfer, too procedural patterned, with single form teaching, which slowly fails...
