文摘The association between the exposure of organochlorine pesticides(OCPs)and serum uric acid(UA)levels remained uncertain.In this study,to investigate the combined effects of OCP mixtures on hyperuricemia,we analyzed serum OCPs and UA levels in adults from the National Health and Nutrition Examination Survey(2005–2016).Four statistical models including weighted logistic regression,weighted quantile sum(WQS),quantile g-computation(QGC),and bayesian kernel machine regression(BKMR)were used to assess the relationship between mixed chemical exposures and hyperuricemia.Subgroup analyses were conducted to explore potential modifiers.Among 6,529 participants,the prevalence of hyperuricemia was 21.15%.Logistic regression revealed a significant association between both hexachlorobenzene(HCB)and trans-nonachlor and hyperuricemia in the fifth quintile(OR:1.54,95%CI:1.08–2.19;OR:1.58,95%CI:1.05–2.39,respectively),utilizing the first quintile as a reference.WQS and QGC analyses showed significant overall effects of OCPs on hyperuricemia,with an OR of 1.25(95%CI:1.09–1.44)and 1.20(95%CI:1.06–1.37),respectively.BKMR indicated a positive trend between mixed OCPs and hyperuricemia,with HCB having the largest weight in all three mixture analyses.Subgroup analyses revealed that females,individuals aged 50 years and above,and those with a low income were more vulnerable to mixed OCP exposure.These results highlight the urgent need to protect vulnerable populations from OCPs and to properly evaluate the health effects of multiple exposures on hyperuricemia using mutual validation approaches.

文摘Japan recently announced the plan to discharge over 1.2 million tons of radioactive water into the Pacific Ocean,which contained hazardous radionuclides such as^(60)Co,^(90)Sr,^(125)Sb,^(129)I,^(3)H,^(137)Cs,and^(99)TcO^(4)^(-),etc.The contaminated water will pose an enormous threat to global ecosystems and human health.Developing materials and technologies for efficient radionuclide removal is highly desirable and arduous because of the extreme conditions,including super acidity or alkalinity,high ionic strength,and strong ionizing radiation.Recently,advanced porous material,such as porous POPs,MOFs,COFs,PAFs,etc.,has shown promise of improved separation of radionuclides due to their intrinsic structural advantages.Furthermore,emerging technologies applied to radionuclide removal have also been summarized.In order to better deal with radionuclide contamination,higher requirements for the design of nanomaterials and technologies applied to practical radionuclide removal are proposed.Finally,we call for comprehensive implementation of strategies and strengthened cooperation to mitigate the harm caused by radioactive contamination to oceans,atmosphere,soil,and human health.

文摘Nanoscale zero-valent iron loaded on biochar(nZVI@BC)has been proven to be effective in activating persulfate to remediate soil organic pollutants.However,studies on subsequent plant growth and microbial community changes in remediated soil remain limited.In this study,nZVI@BC,nZVI,and nanoscale biochar(nBC)were ballmill produced and applied as amendments in pot experiments with PAH-contaminated soil to investigate their impacts on soil-crop(radish,Raphanus sativus L.)systems,and the widely distributed phenanthrene(Phe)was selected as model pollutant.The results indicate that nZVI@BC could induce more(75%)Phe accumulation in radish compared to the control treatment,but did not result in significant differences in plant biomass or enzyme activity.In non-contaminated treatments,the Fe content of radish shoots increased from 86.875.61 mg/kg DW without material application to 125.2011.93 mg/kg DW with nZVI@BC,while no significant differences were observed in roots.nZVI@BC and nBC increased the non-desorbed fraction of PAHs with low bio-availability by 13.6%and 10.2%,respectively,after 45 days compared to the control treatment.Illumina MiSeq sequencing revealed that nZVI@BC did not adversely affect the richness and diversity of soil microbial communities.Instead,it promoted the enrichment of bacteria related to the degradation of organic pollutants,such as Lysobacter and Spingomonas.The findings suggest that nZVI@BC after chemical oxidation remediation might be harmful to subsequent plants and ecosystems but much better than nZVI alone.The amount of nZVI@BC should be accurately calculated before chemical oxidation remediation.

文摘This study aims to evaluate the association between social determinants,environmental exposure metrics,and the risk of asthma emergency department(ED)visits in the New York State(NYS)Medicaid population using smallarea analysis.Traffic densities for each census tract in NYS were calculated using the length of road segments within each tract and total area of the tract to produce a measure of average number of vehicles per square meter per day.Data on social determinants of health including internal and external environments and other demographic factors were obtained from various sources.Poisson regression analyses were conducted to identify significant factors associated with asthma ED visits in Medicaid claim and encounter data for years 2005–2015.High traffic density in NYS excluding New York City(NYC)correlated with increased risk of asthma ED visits(RR 1.69;95%CI:1.42,2.00),mitigated by adjusting for environmental and social determinants(RR 1.00;95%CI:0.85,1.19).Similar trends were observed in NYC only(RR 1.19;95%CI:1.00,1.41),with the adjusted risk remaining elevated(RR 1.14;95%CI:0.98,1.33)albeit not statistically significant.Living in census tracts with high concentrated disadvantage index,high proportions of minorities,and less green space predicted higher asthma ED visits.We mapped predicted rates and model residuals to identify areas of high risk.Our results support previous findings that environmental and social risk factors in poor and urban areas contribute to asthma exacerbations in the NYS Medicaid population,even if they may not necessarily contribute to its development.

文摘Ambient particles severely threaten human health worldwide.Compared to larger particles,ultrafine particles(UFPs)are highly concentrated in ambient environments,have a larger specific surface area,and are retained for a longer time in the lung.Recent studies have found that they can be transported into various extra-pulmonary organs by crossing the air-blood barrier(ABB).Therefore,to understand the adverse effects of UFPs,it is crucial to thoroughly investigate their bio-distribution and clearance pathways in vivo after inhalation,as well as their toxicological mechanisms.This review highlights emerging evidence on the bio-distribution of UFPs in pulmonary and extra-pulmonary organs.It explores how UFPs penetrate the ABB,the blood-brain barrier(BBB),and the placental barrier(PB)and subsequently undergo clearance by the liver,kidney,or intestine.In addition,the potential underlying toxicological mechanisms of UFPs are summarized,providing fundamental insights into how UFPs induce adverse health effects.

文摘Cerebral small vessel disease(CSVD),a chronic and progressive vascular disorder closely associated with stroke and dementia,is primarily identified and diagnosed in cranial magnetic resonance imaging(MRI).Given the limited evidence on the relationship between air pollution and CSVD,this study aimed to investigate the links between multiple air pollutants exposure and CSVD risk.Eligible subjects and their cranial MRI data were obtained from the Multi-modality Medical Imaging Study Based on Kailuan Study,totaling 1216 participants.Ordinal and binary logistic regression models were utilized to evaluate the associations between air pollution exposure and the neuroimaging markers of CSVD.For each interquartile range increase in air pollutant exposure during the examination year,the odds ratios and 95% confidence intervals of the increased white matter hyperintensity burden were 1.45(1.15,1.84)for PM_(2.5),1.72(1.27,2.34)for PM_(10),1.26(1.05,1.51)for SO_(2),1.52(1.16,2.00)for NO_(2),and 1.63(1.26,2.13)for CO.The results remained consistent even when the model was fitted using air pollution from different exposure windows.Furthermore,the estimated effect sizes for the total burden of CSVD were 1.20(1.01,1.43)for PM_(2.5),1.39(1.12,1.74)for PM_(10),1.26(1.03,1.53)for NO_(2),and 1.30(1.08,1.58)for CO.These findings suggest that a positive link between air pollutants exposure and neuroimaging markers of CSVD in the Chinese population,revealing the importance of controlling environmental pollutants to protect the population against cerebral small vessel damage.

文摘Aerosol transmission has been officially recognized by the world health authority resulting from its overwhelming experimental and epidemiological evidences.Despite substantial progress,few additional actions were taken to prevent aerosol transmission,and many key scientific questions still await urgent investigations.The grand challenge,the effective control of aerosol transmission of COVID-19,remains unsolved.A better understanding of the viral shedding into the air has been developed,but its temporal pattern is largely unknown.Sampling tools,as one of the critical elements for studying SARS-CoV-2 aerosol,are not readily available around the world.Many of them are less capable of preserving the viability of SARS-CoV-2,thus offering no clues about viral aerosol infectivity.As evidenced,the viability of SARS-CoV-2 is also directly impacted by temperature,humidity,sunlight,and air pollutants.For SARS-CoV-2 aerosol detection,liquid samplers,together with real-time polymerase chain reaction(RT-PCR),are currently used in certain enclosed or semi-enclosed environments.Sensitive and rapid COVID-19 screening technologies are in great need.Among others,the breath-borne-based method emerges with global attention due to its advantages in sample collection and early disease detection.To collectively confront these challenges,scientists from different fields around the world need to fight together for the welfare of mankind.This review summarized the current understanding of the aerosol transmission of SARS-CoV-2 and identified the key knowledge gaps with a to-do list.This review also serves as a call for efforts to develop technologies to better protect the people in a forthcoming reopening world.

文摘Evaluating the plant risk of soil pollution by plant physiological indices usually requires a long cycle and has significant uncertainty.In this study,oxidative potential(OP)of the in situ heavy metal contaminated soils was measured by the dithiothreitol method.The oxidative stress response of the model plant ryegrass(Lolium perenne L.)induced by heavy metal contaminated soil was evaluated by the biomarkers,including superoxide dismutase and total antioxidant capacity.The comprehensive biomarker response index has a significant exponential correlation with the OP of soil(r¼0.923,p<0.01)in ryegrass.Metabolomics analysis also showed a significant relationship of the metabolic effect level index of amino acids and sugars with OP.Random forest was selected from four machine learning models to screen the metabolites most relevant to OP,and Shapley additive explanations analysis was used to explain the contribution and the influence direction of the features on the model.Based on the selected 20 metabolites,the metabolic pathways most related to OP in plants,including alkaloid synthesis and amino acids metabolism,were identified.Compared to the plant physiological indices,OP is a more stable and faster indicator for the plant risk assessment of heavy metals contaminated soil.

文摘Human-induced inputs of nitrogen(N)and phosphorus(P)into the biosphere have reached unprecedented levels,particularly N,leading to an escalating global anthropogenic N:P ratio.This ratio has emerged as a significant driver of environmental change,impacting organisms,ecosystems,and global food security.However,the implications of this ratio for human health have been largely overlooked and remain uncertain.This article aims to fill this knowledge gap by exploring the potential effects of N:P ratios on both non-infectious and infectious diseases.Preliminary data emphasize the importance of investigating the influence of N:P ratios on human health,suggesting a potential role in the rise of non-infectious diseases,such as cancer,as well as the proliferation of infectious diseases,including Zika and malaria.These findings highlight the urgent need for increased attention from the scientific community and policymakers regarding the complex impacts of the human-induced biospheric N:P ratio.It is crucial to investigate and understand the underlying mechanisms and drivers behind these effects.Furthermore,there is significant potential for improving human health through the manipulation of N:P ratios and the availability of N and P.This applies not only to medical treatments but also to innovative fertilizer management strategies.These avenues present promising opportunities to address the challenges associated with human health in an ever-changing world.

文摘Global biodiversity is the most essential component of the planet,and the Kunming-Montreal Global Biodiversity Framework(GBF)has been unanimously adopted by 196 parties worldwide in 2022 to achieve the global vision of a world of living in harmony with nature by 2050.Of particular importance is the timely update of the National Biodiversity Strategies and Action Plans(NBSAPs)and/or National Targets aligned with the GBF before the sixteenth meeting of the Conference of the Parties(COP16)to the Convention on Biological Diversity.Upon comprehensive evaluation of updated NBSAPs of 47 parties and updated national targets of 126 parties,we proposed pathways that could better inform the updating processes.First,the essential elements of the goals and targets of the GBF applicable to national circumstances should be equivalently translated into national policies and instruments.Second,when specific national circumstances do not match with those essential elements,parties need to determine their own national biodiversity targets based on their situation but in a way that maintains and reflects the ambition of the GBF.Furthermore,the key factors that promote the success of biodiversity conservation are highlighted in terms of the target alignment with the GBF,the ownership enhancement,and the capacity building.We anticipate that these measures could facilitate immediate actions to update the NBSAPs to align with the GBF at the highest level while remaining cost-effectiveness.

文摘Fungi are widely distributed in the environment,and some are beneficial to medicine,industry,agriculture,and food.For example,Penicillium chrysogenum,Acremonium chrysogenum,and Aspergillus terreus can synthesizeβ-lactams,which can be used as drugs[1];Aspergillus niger and Trichoderma reesei are well-known industrial enzyme producers[2].
文摘The occurrence of per-and polyfluoroalkyl substances(PFAS)in water cycles poses a challenge to drinking water quality and safety.In order to counteract the large knowledge gap regarding PFAS in German drinking water,89 drinking water samples from all over Germany were collected with the help of residents and were analyzed for 26 PFAS by high-performance liquid chromatography with tandem mass spectrometry(HPLC-MS/MS).The 20 PFAS recently regulated by sum concentration(PFAS_(∑20)),as well as six other PFAS,were quantified by targeted analysis.In all drinking water samples,PFAS_(∑20 )was below the limit of 0.1μg/L,but the sum concentrations ranged widely from below the limit of quantification up to 80.2 ng/L.The sum concentrations(PFASP4)of perfluorohexanesulfonate(PFHxS),perfluorooctanesulfonate(PFOS),perfluorooctanoate(PFOA),and perfluorononanoate of 20 ng/L were exceeded in two samples.The most frequently detected individual substances were PFOS(in 52%of the samples),perfluorobutanesulfonate(52%),perfluorohexanoate(PFHxA)(44%),perfluoropentanoate(43%)and PFHxS(35%).The highest single concentrations were 23.5 ng/L for PFHxS,15.3 ng/L for PFOS,and 10.1 ng/L for PFHxA.No regionally elevated concentrations were identified,but some highly urbanized areas showed elevated levels.Concentrations of substitution PFAS,including 2,3,3,3-tetrafluoro-2-(heptafluoropropoxy)propanoate and 2,2,3-trifluor-3-[1,1,2,2,3,3-hexafluor-3-(trifluormethoxy)propoxy]-propanoate(anion of ADONA),were very low compared to regulated PFAS.The most frequently detected PFAS were examined for co-occurrences,but no definite correlations could be found.
文摘Biodiversity is undergoing unprecedented changes characterized by long-term,complex,and lagging consequences[1].Understanding the dynamic changes of biodiversity is essential for the conservation of biodiversity[2].Biodiversity monitoring is periodic measurements of biodiversity within a given area,such as data collection regarding the structure and function of ecosystems,the composition and distribution of species,and environmental factors.Based on the collected data,analyses could be performed to determine the trends of biodiversity change and potential drivers and assist in the evaluation of conservation effectiveness and decision-making[2,3].
