Per-and poly-fluoroalkyl substances(PFAS)have garnered significant global attention due to their widespread presence and potential environmental and health risks.However,research on the occurrence and environmental behavior of PFAS across different media remains limited.We analyzed the occurrence,distribution,sources,and ecological risks of 32 PFAS across multiple media in the Weihe River,China.The concentrations of PFAS ranged from 5.89 to 472.84 ng/L in the pore water and from 9.93 to 459.50 ng/L in surface water,exhibiting significant spatial variability(P<0.05).In contrast,the PFAS concentration range in the sediments was 0.74-1.81 ng/g dry weight,with no pronounced spatial variation in solid-phase PFAS(P>0.05).Vertically,concentrations in 33.00%of pore water samples exceeded those in surface water,showing a heterogeneous vertical distribution with enrichment at depths of 40-60 cm.The physical-chemical characteristics of PFAS and the hydrological and sedimentary processes at the basin scale were responsible for PFAS partitioning between the aquatic environment and sediments.Four major sources were identified through integrated source apportionment:industrial and domestic wastewater(58.25%),aqueous film-forming foam(18.07%),combined input from household pollution and metal plating(8.70%),and stormwater runoff and landfill leachate(14.98%).The ecological risk assessment revealed negligible risks from short-chain PFAS in surface water and pore water,whereas long-chain PFAS posed low to moderate ecological risks.Furthermore,the discharge of PFAS from the Weihe River to the Yellow River was estimated up to 708.20 kg/a.This study provides critical data informing strategies for mitigating PFAS pollution in rivers across typical arid and semi-arid areas of China. 展开更多

Although activated carbon filters are thought to be the best way to remove per-and polyfluorinated alkyl substances(PFAS),it is yet unknown how biofilms affect PFAS removal.This study first examined how the removal of PFAS in full-scale drinking water treatment plants(DWTPs)was impacted by biofilm from biological activated carbon(BAC)of varying depths and carbon ages.PFAS desorption from BAC was visible,but at this point,BAC could still remove dissolved organic matter(DOM)efficiently.Studies have demonstrated that the use of activated carbon filters can dramatically lower the content of PFAS in water,with the amount of PFAS reducing as the filter’s depth grows and its use duration increases.Additionally,pore-clogging becomes more noticeable as the biofilm ages,which reduces BAC’s capacity to eliminate PFAS and hinders PFAS desorption.Furthermore,the adsorption process of PFAS may be impeded by the secretion of biofilms,which are composed of proteins and polysaccharides.Based on the analysis above,it can be the adsorption of PFAS by BAC is significantly inhibited by biofilms,according to another research.This provides theoretical direction for improving the removal effectiveness of PFAS in DWTPs. 展开更多

Fe reducing bacteria(FRB),through extracellular electron transfer(EET)pathway,can reduce Fe(III)nanoparticles,thereby affecting the migration,transformation,and degradation of pollutants.However,the interaction of Fe(III)nanoparticles with the most commonly identified FRB,Geobacter sulfurreducens PCA,remains poorly understood.Herein,we demonstrated that the synergistic role of outer membrane proteins and periplasmic proteins in the EET process for-Fe_(2)O_(3),Fe3O4,and𝛽α-FeOOH nanoparticles by construction of multiple gene knockout strain.oxpG(involved in the type II secretion system)and omcST(outer membrane c-type cytochrome)medi-ated pathways accounted for approximately 67%of the total reduction of𝛼α-Fe_(2)O_(3) nanoparticles.The residual reduction of𝛼α-Fe_(2)O_(3) nanoparticles in∆oxpG-omcST strain was likely caused by redox-active substances in cell supernatant.Conversely,the reduction of dissolved Fe(III)was almost unaffected in∆oxpG-omcST strain at the same concentration.However,at high dissolved Fe(III)concentration,the reduction significantly decreased due to the formation of Fe(III)nanoparticles,suggesting that this EET process is specific to Fe(III)nanoparticles.Overall,our study provided a more comprehensive understanding for the EET pathways between G.sulfurreducens PCA and different Fe(III)species,enriching our knowledge on the role of microorganisms in iron biogeochemical cycles and remediation strategies of pollutants. 展开更多

Arsenic(As)pollution seriously threatens human and ecological health.Microalgal cell wall and extracellular polymeric substances(EPS)are known to interactwith As,but their roles in the As resistance,accumulation and speciation inmicroalgae remain unclear.Here,we used two strains of Chlamydomonas reinhardtii,namely CC-125(wild type)and CC-503(cell walldeficientmutant),to examine the algal growth,EPS synthesis,As adsorption,absorption and transformation under 10–1000μg/L As(III)and As(V)treatments for 96 h.In both strains,the As absorption increased after the EPS removal,but the growth,As adsorption,and transformation of C.reinhardtii declined.The CC-125 strain was more tolerant to As stress and more efficient in EPS production,As accumulation,and redox transformation than CC-503,irrespective of EPS presence or absence.Three-dimension excitation-emission matrix(3DEEM)and attenuated total reflectance infrared spectroscopy(ATR-IR)analyses showed that As was bound with functional groups in the EPS and cell wall,such as-COOH,NH and-OH in proteins,polysaccharides and amino acids.Together,this study demonstrated that EPS and cell wall acted as barriers to lower the As uptake by C.reinhardtii.However,the cell wall mutant strain wasmore susceptible to As toxicity due to lower EPS induction and higher As absorption. 展开更多

Due to their persistence,bioaccumulation,and resistance to degradation,perfluorinated substances(PFASs)have significant impacts on the environment and human health.This study comprehensively analyzed and assessed the occurrence characteristics,sources,and potential ecological risks of 13 PFASs in the Yangtze River.The results indicated that the concentrations ofΣPFASs range from 5.1 to 57.7 ng/L,with more severe pollution downstream and perfluorobutane sulfonate(PFBuS)being the main pollutant.ΣPFASs showed a positive correlation with total organic carbon and absorbance under the condition of UV wavelength 254 nm(UV_(254)),and a negative correlation with total dissolved solids.Positive matrix factorization model analysis revealed that the primary sources of PFASs in the study area are food packaging,the electroplating industry,and the manufacturing and processing of fluoropolymer-containing products.The total ecological risk value of PFASs indicated that the ecological risks to algae,invertebrates,and fish are negligible.The annual load of ΣPFASs in the Yangtze River was 39.00 t,with the highest concentrations of pollutants being PFBuS(26.41 t/year),perfluorobutanoic acid(6.47 t/year),and perfluorooctanoic acid(PFOA,3.19t/year).While PFASs have not yet posed a risk to aquatic organisms,the increase in the use of short-chain PFASs substitutes(C4-C7)due to the regulation of PFOA and perfluorooctane sulfonate highlights the need for continued monitoring of short-chain PFASs pollution. 展开更多

Spider mites are significant pests in agricultural production.The increasing resistance of spider mites,along with environmental pollution and ecological imbalance caused by their control,is primarily attributed to the long-term use of chemical acaricides in agriculture.In contrast,bioactive substances of biological origin offer advantages such as wide availability,environmental friendliness,and low tendency to induce resistance,making them a research hotspot for spider mite control.This review summarizes recent advances in the use of plant-derived active compounds(exemplified by extracts from Veratrum rhizomes),RNA interference(RNAi)technology,and microorganism-derived active substances for controlling spider mites.These bioactive agents exert acaricidal effects by disrupting the nervous system,interfering with metabolic processes,or silencing key genes in mites,demonstrating favorable efficacy and considerable potential for development.However,challenges remain,including poor environmental stability,slow action,high production costs,and insufficient understanding of their effects on non-target organisms.Therefore,future research should focus on the screening and development of novel bioactive substances of biological origin,elucidation of their mechanisms of action,optimization of formulation technologies,and assessment of their ecological safety.These efforts will provide valuable insights for promoting the advancement of bioactive substances and supporting sustainable agricultural development. 展开更多

Purpose: The aim of the study was to investigate the profile of psychoactive substance users in Senegal from 2018 to 2022. Methodology: These were retrospective descriptive studies of patient consultation and hospitalization records in the 17 psychiatric and addictology care centers in Senegal from 2018 to 2022. This was an exhaustive survey. All usable consultation and hospitalization registers were included in the study. Non-usable consultation and hospitalization registers were not included. Data were collected from January 1 to December 31 of each respective year. Data were cleaned using Excel before analysis. R software version 4.3.3 was used for analysis. Results: Between 2018 and 2022, 26,029 patients were registered in mental health facilities in Senegal. The Fann Psychiatry Department (CHNU Fann) admitted 23.2% of patients and the Thiaroye National Psychiatric Hospital registered 17.6% of drug users. For the year 2019, we found 8259 and in 2021, we had 6607 patients. The male gender was more represented with 14,750 patients, or 90.9%. The age group [25 - 34] was the majority (7013 patients or 39.5%). The majority of patients (17,425 patients, or 84.6%) were followed as outpatients. The drugs were mainly inhaled (96.7%). The most consumed substance was cannabis with 8847 patients, or 54.2%. Withdrawal was the main reason for treatment, 11,614 patients, or 85.7%. Conclusion: In the light of the results of our study, we can say that the use of psychoactive substances is a real public health and development problem in Senegal. The peaks in psychoactive substance consumption preceded the peaks in psychiatric care centers, so we need to promote information, education and communication on the harmful effects of psychoactive substance consumption among the population in general and young people in particular, in order to safeguard the country’s development. 展开更多

Work-related stress has become an alarming reality that continues to intensify over the past decades. The pressure exerted by the work environment demands the utilization of defensive and coping strategies to deal with it. Our study aims to explore the relationship between professional stress factors, stress symptoms, and the consumption of psychoactive substances as a defensive and coping strategy deployed to address psychological distress at work. A qualitative and quantitative study was conducted with a sample of 405 employees from a wiring manufacturing. The main professional stress factors identified were concentration, overload, long working hours, and monotony, which showed a significant correlation with PAS consumption. Women were found to be more affected by stress and tended to consume more sedatives. Among the respondents, 21.98% reported PAS consumption, with tobacco being the most commonly used (M = 2.66), followed by alcohol (M = 1.94), cannabis (M = 1.79), and sedatives (M = 1.45). There was a significant positive correlation between PAS consumption and stress symptoms {tobacco (r = 0.232*), alcohol (r = 0.305**), cannabis (r = 0.389**)}. 展开更多

Based on the energy dissipation caused by consolidation deformation of the porous media under external force and migration of the internal suspended substances,a coupled multiphase-substance flow(CMF)model was established.This model introduced the new concepts,such as particle temperature and particle entropy,to describe energy dissipation at meso-level.This model used a potential energy density function and migration coefficients to establish the corresponding connection between the dissipative force and dissipative flow.This viewpoint unifies the deformation,seepage,and suspended substance migration of geotechnical materials under the framework of granular thermodynamics.It can reflect the evolution of effective stress in the solid matrix of multi-components in a particle-reorganized state,and considers the temperature driving effect.The proposed CMF model is validated using the experimental results under coupled migration of heavy metal ions(HMs)and suspended particles(SPs).The calculation results demonstrated that the CMF model can describe the flow process under the conditions of arbitrary changes in different suspended substance types,injection concentrations,and injection velocities. 展开更多

Fermented sour soup is a unique traditional sour food of the Miao and Dong ethnic groups in China.However,due to the commonly used traditional fermentation,the unstable fluctuation of microbial community often leads to some unpleasant inherent off-flavours in rice sour soup.In this study,the microbial composition and volatile flavour components of off-flavour and normal rice sour soup were examined by high-throughput sequencing and headspace solid-phase microextraction coupled with gas chromatography mass spectrometry.Then,based on Pearson correlation coefficients,the correlations between fungi and bacteria and those between core microorganisms and key volatile flavour components were investigated.The dominant fungal genera included Candida,Dekkera,Pichia,Rhizopus,and Issatchenkia,whereas the dominant bacterial genera included Lactobacillus,Pectinatus,Bifidobacterium,Pseudomonas,and Acetobacter.Compared to normal rice sour soup,off-flavoured rice sour soup contained the significantly increased relative abundance of Candida and the significantly decreased relative abundance of Dkkera.In addition,80 volatile flavour compounds detected in off-flavoured rice sour soup,mainly including esters,acids,and alcohols,were different from those detected in normal rice sour soup.Especially,some substances were only detected in off-flavoured rice sour soup,such as 1-hexanol(68-207μg/kg),butyric acid(20-92μg/kg)and heptanoic acid(12-45μg/kg),which might be the main source of off-flavours.These results provide new ideas and strategies of removing or abating odour from fermented rice sour soup. 展开更多

Objective To investigate the associations between eight serum per-and polyfluoroalkyl substances(PFASs)and regional fat depots,we analyzed the data from the National Health and Nutrition Examination Survey(NHANES)2011-2018 cycles.Methods Multiple linear regression models were developed to explore the associations between serum PFAS concentrations and six fat compositions along with a fat distribution score created by summing the concentrations of the six fat compositions.The associations between structurally grouped PFASs and fat distribution were assessed,and a prediction model was developed to estimate the ability of PFAS exposure to predict obesity risk.Results Among females aged 39-59 years,trunk fat mass was positively associated with perfluorooctane sulfonate(PFOS).Higher concentrations of PFOS,perfluorohexane sulfonate(PFHxS),perfluorodecanoate(PFDeA),perfluorononanoate(PFNA),and n-perfluorooctanoate(n-PFOA)were linked to greater visceral adipose tissue in this group.In men,exposure to total perfluoroalkane sulfonates(PFSAs)and long-chain PFSAs was associated with reductions in abdominal fat,while higher abdominal fat in women aged 39-59 years was associated with short-chain PFSAs.The prediction model demonstrated high accuracy,with an area under the curve(AUC)of 0.9925 for predicting obesity risk.Conclusion PFAS exposure is associated with regional fat distribution,with varying effects based on age,sex,and PFAS structure.The findings highlight the potential role of PFAS exposure in influencing fat depots and obesity risk,with significant implications for public health.The prediction model provides a highly accurate tool for assessing obesity risk related to PFAS exposure. 展开更多

Per-and polyfluoroalkyl substances(PFASs)can induce a range of adverse health effects,with the precise molecularmechanisms remaining elusive.Extracellular vesicles(EVs)have demonstrated their potential to elucidate unknown molecular mechanisms.Building upon the close alignment of their biological functions with the observed health effects of PFASs,this study innovatively focuses on proteomic insights from EVs into the molecular mechanisms underlying the systemic health effects of PFASs.Through rat exposure experiments and proteomics technology,it not only demonstrated the occurrence of PFASs in EVs but also revealed the alterations in the serum EVs and the expression of their protein cargos following mixed exposure to PFASs,leading to changes in related pathways.These changes encompass various biological processes,including proteasome activity,immune response,cytoskeletal organization,oxidative stress,cell signaling,and nervous system function.Particularly noteworthy is the uncovering of the activation of the proteasome pathway,highlighting significant key contributing proteins.These novel findings provide a new perspective for exploring the molecularmechanism underlying the systemic health effects of PFASs and offer reliable screening for potential biomarkers.Additionally,comparisons with serum confirmed the potential of serum EVs as biological responders and measurable endpoints for evaluating PFASs-induced toxicity. 展开更多

The optical absorption of large molecular compounds HULIS(humic-like substances)can significantly impact the aerosol light absorption and radiative forcing,influencing cloud condensation nuclei formation and thus the climate and atmospheric environment.This study collected aerosol(PM_(2.5))samples from the summit of Mount Tai in North China to investigate the concentration,molecular composition,and optical properties of HULIS.The average concentration of HULIS in the PM_(2.5) in this study was 1.26±0.54μg/m^(3),comprising for 56%of the water-soluble organic carbon(WSOC),with levels lower than urban areas but higher than other mountainous regions.Mass spectrometry revealed that CHO and CHON components,with high aromaticity and phenolic groups,are major contributors to absorption and fluorescence.These results indicate that HULIS is mainly composed of lignin and proteins/amino sugars,derived from combustion and secondary formation,and possesses a high light absorption capacity(withMAE365(mass absorption efficiency)and AAE(A˚ngstrom exponent)indices of 0.62m^(2)/g and 4.99,respectively).Parallel factor analysis identified three fluorescence components of HULIS,with proportions of 60.8%for less oxygen humic-like substances,21.0%for high oxygen humic-like substances,and 18.2%for protein-like substances.Our study highlights the significance of the light-absorbing capacity and secondary formation of HULIS at Mount Tai,laying the groundwork for investigation into the climate effects,formation mechanisms,and sources of HULIS generation. 展开更多

Perfluoroalkyl and polyfluoroalkyl substances(PFASs)pollution with their toxicity,carcinogenicity,and persistence has been concerned worldwide.Research into novel materials for detecting and removing PFASs has increased rapidly,particularly in regard to the emergence of well-characterized single-atom materials(SAMs).Owing to the high selectivity,high atom utilization,and abundant active sites of SAMs,these materials exhibit remarkable efficacy in the detection and removal of PFASs.In this work,recent advances in the synthesis of SAMs for the detection and removal PFASs are reviewed.In-depth discussions of the structure-activity relationship and reaction mechanisms have demonstrated the high efficiency,activity,and selectivity of SAMs for the detection,adsorption,and degradation of PFASs.To optimize the application of SAMs in PFASs remediation,this review comprehensively surveys SAMs applications for PFASs and analyzes potential design strategies based on synthesis methods and corresponding properties.Synthesis strategies such as wet-chemistry,which offer ease of operation and high potential for large-scale production,are recommended for the further exploration of specific SAMs for the detection and removal of PFASs.Finally,this review identifies the challenges and opportunities for development of SAMs for the detection and remediation of PFASs,providing an outlook on strategic goals for a green economy and sustainable development. 展开更多
