Widespread environmental contamination of legacy long-chain poly- and per-fluoroalkyl substances (PFASs) has triggered chemical regulatory action a global transitioning to alternative PFASs. More than 5000 PFASs are now recognized on various lists, but few have been monitored despite ample evidence unidentified organic fluorine in human samples. Nevertheless, our review the literature indicates that nontarget analytical methods based high-resolution mass spectrometry used discover more 750...
Abstract Background The NORMAN Association ( https://www.norman-network.com/ ) initiated the Suspect List Exchange (NORMAN-SLE; https://www.norman-network.com/nds/SLE/ in 2015, following collaborative trial on non-target screening of environmental water samples by mass spectrometry. Since then, this exchange information chemicals that are expected to occur environment, along with accompanying expert knowledge and references, has become a valuable base for “suspect screening” lists....
Abstract Exposure of polar bears ( Ursus maritimus ) to persistent organic pollutants was discovered in the 1970s, but recent evidence suggests presence unknown toxic chemicals their blood. Protein and phospholipid depleted serum stirred with polyethersulfone capillaries extract a broad range analytes, nontarget mass spectrometry “fragmentation flagging” used for detection. Hundreds analytes were belonging 13 classes, including novel polychlorinated biphenyl (PCB) metabolites many...
Nontarget high-resolution mass spectrometry (Nt-HRMS) has been proven useful for the identification of unknown poly- and perfluoroalkyl substances (PFASs) in commercial products water, but applications to biological samples are limited. China is major PFAS-manufacturing nation; thus, here, we adapted our Nt-HRMS methods fish collected from Yangtze River Tangxun Lake discover potentially bioaccumulative PFASs aquatic organisms destined human consumption. In addition traditional PFASs, over...
We have been effectively protected by disposable propylene face masks during the COVID-19 pandemic; however, they may pose health risks due to release of fine particles and chemicals. measured micro/nanoparticles organic chemicals in medical masks, surgical (K)N95 respirators. In breathing-simulation experiment, no notable differences were found total number among mask types or between breathing intensities. However, when considering subranges, <2.5 μm accounted for ∼90% micro/nanoparticles....

The global practice of reusing sewage sludge in agriculture and its landfill disposal reintroduces environmental contaminants, posing risks to human ecological health. This study screened from 30 Chinese cities for androgen receptor (AR) disruptors, utilizing a disruptor list the Toxicology 21st Century program (Tox21), identified 25 agonists 33 antagonists across diverse use categories. Predominantly, natural products 5α-dihydrotestosterone thymidine emerged as agonists, whereas industrial...
Groundwater can be contaminated by PFAS emissions, yet research on the presence and associated risks of in groundwater underlying different land-use areas remains limited. Herein, high-resolution mass spectrometry-based suspect nontarget analyses were performed to determine occurrence samples obtained from a rural area, planting region, vicinities pharmaceutical park, an airport, industrial park Datong City, China. A total 31 (16 emerging 15 legacy PFAS) identified, ΣPFAS concentrations...
Directly synthesizing NH3 and NOx from N2 H2O by nonthermal plasma(NTP) at atmospheric pressure low temperature is considered an attractive alternative for the Haber-Bosch process. Nonthermal plasma integrated...
Based on high-resolution mass spectrometry (HRMS), nontarget analysis (NTA) can rapidly identify and characterize numerous hazardous substances in complex environmental samples. However, the intricate identification process often results underutilization of many features. Even when chemical structures are identified, their toxicological effects health outcomes may remain unknown. To address these challenges, this study introduces MSFragTox, a novel approach that leverages rich fragmentation...
Despite extensive poly/perfluoroalkyl substance (PFAS) discovery studies in various samples, the exposure spectrum fluorochemical occupational workers remains largely unexplored. Here, serum samples from 28 at a facility were analyzed using nontarget techniques, identifying 64 PFAS classes, including 15 novel ones such as pentafluorosulfur ether-substituted perfluoroalkyl sulfonic acids, hydrogen-substituted perfluoroalkylamines, and perfluoroalkylsulfonyl protocatechualdehyde esters....
Triazine herbicides (THs) are used globally to control weeds in urban environments, but their transformation products (TPs) rarely considered due the lack of reference standards. In this study, a total 41 TPs were found wastewater influents and effluents 28 municipal treatment plants (MWWTPs) from six cities China by integrating suspect screening (36 TPs), molecular networking (9 diagnostic fragment searching (12 TPs). Among these, 36 detected for first time aquatic reported environments....
There is growing evidence that the transformation products of emerging contaminants in foodstuffs may pose a health risk to humans. However, exact identities, levels, and estimated dietary intake (EDI) neonicotinoid crops remain poorly understood. We established an extended suspect screening strategy investigate insecticides their retail cowpea from 11 cities Hainan Province, China. Forty-nine were identified cowpea, which 22–36 found 98.6% samples. Notably, 31 new derived processes or...
Although rubber shoes have been extensively produced and used for the past century, chemical additives released from shoe soles, as well aquatic ecological risks, overlooked. Using nontargeted analysis, this study detected 106 70 chemicals in soles leachates, respectively. The total concentrations were range of 203 to 3.21 × 103 μg/g 247 5.32 104 μg/L leachates. distributed 10 groups, among which phthalate esters dominant additives.
