Abstract. Open biomass burning is an important source of air pollution in China and globally. Joint observations were conducted five cities (Shanghai, Hangzhou, Ningbo, Suzhou Nanjing) the Yangtze River delta, a heavy haze episode with visibility 2.9–9.8 km was observed from 28 May to 6 June 2011. The contribution quantified using both ambient monitoring data WRF/CMAQ (Weather Research Forecasting (WRF) Community Multiscale Air Quality (CMAQ)) model simulation. It found that average maximum...
Fine particulate matter (PM2.5) can promote chronic diseases through the fundamental mechanism of inflammation; however, systemic information is lacking on inflammatory PM2.5 components. To decipher organic components from personal exposure that were associated with respiratory and circulatory responses in older adults, we developed an exposomic approach using trace amounts particles applied it 424 samples collected a panel study Beijing. Applying integrated multivariate univariate...
Electrophilic compounds belong to a group of critical components fine particulate matter (PM2.5) with significant health risk, but little is known regarding their occurrence and sources in the atmosphere. In this study, we developed nontargeted approach analyze electrophilic urban Beijing identified 147 ones diurnal variation, among which oxygenated aromatic (OACs) are predominant species. The discrepancy hierarchical clustering analysis atmospheric transformation markers, e.g.,...
Fine particulate matter (PM
Hepatic steatosis is the first step in a series of events that drives hepatic disease and has been considerably associated with exposure to fine particulate matter (PM2.5). Although chemical constituents particles negative health effects, specific components PM2.5 trigger remain unclear. New strategies prioritizing identification key highest potential cause adverse effects among numerous are needed. Herein, we established high-resolution mass spectrometry (MS) data set comprising hydrophobic...
BackgroundGlobally, there have been many cases of coronavirus disease 2019 (COVID-19) among medical staff; however, the main factors associated with infection are not well understood.AimTo identify super-factors causing COVID-19 in staff China.MethodsA cross-sectional study was conducted between January 1st and February 30th, 2020, which front-line members who took part care treatment patients were enrolled. Epidemiological demographic data infected uninfected groups collected compared....
Organic nitrates (ONs) are an important component of secondary organic aerosols that play significant roles in atmospheric chemical processes such as ozone formation and a reservoir nitrogen oxides (NOx). However, hindered by the availability analytical techniques, characteristics ON molecules remain unclear regions influenced anthropogenic volatile compounds (VOCs) pollution. In this study, we achieved isomeric identification particle-phase ONs regions. Using gas chromatography...

During megacity lockdown, a team of social work practitioners and researchers in Beijing developed rapid, innovative, Internet-based intervention that provided social-emotional support for participating families through indoor micro-gardening. As COVID-19 continues to restrict in-person interactions traditional activities, this type online community building should become major method crisis service provision.
Ozone (O3) has been implicated in exacerbating the adverse health effects of ambient PM2.5, yet role chemical composition this process remains unclear. This study aimed to systematically evaluate how use O3 enhances inflammation induced by PM2.5 compounds. Utilizing exposomic characterization 1327 compounds personal from a panel elderly urban residents, our analysis revealed that enhanced associations pro-inflammatory biomarkers, i.e., exhaled nitric oxide, interleukin-6, serum...
The ongoing COVID-19 pandemic has motivated social workers to reckon with and transform traditions in service delivery. development, application, evaluation of technology-enhanced practices have become more vital than ever. Garden on the Balcony (GOB) was an innovative internet-based work designed respond rapidly outbreak Beijing. This paper introduces underlying perspectives design GOB reports participants’ reflections program understand its mechanisms implications. Interview data from...
Previous in vitro studies identified carboxylic acids as the major metabolites of methylated polycyclic aromatic hydrocarbons (PAHs). We have previously detected phenanthrene-2-carboxylic acid (2-PHECA) human urine, but a direct linkage between this biomarker and external exposure to PAHs remains unestablished. Herein, we analyzed phenanthrene (PHE) 2-MePHE 589 personal PM2.5 samples hydroxy-phenanthrenes (ΣOH-PHEs) 2-PHECA paired urine from 120 urban residents. observed higher PHE lower...
Pulses are vital for nutrition security and considered a cost-effective option improving the diets of low-income consumers in developing countries. Sub-Saharan Africa has highest proportion people living extreme poverty per capita pulse consumption world. Most studies on demand have largely depended aggregated data at regional level there is little information household patterns across sub-population groups within same geographical location. This study uses most recently collected LSMS-ISA...
Metabolic disorder can exacerbate oxidative damage following exposure to fine particulate matter (PM2.5), but the role of chemical composition in this process remains unclear. This study comprehensively assessed stress effect from synergy metabolic and organic components PM2.5 as well their molecular features. We high-throughput characterized 942 chemicals an elderly urban population found association between markers exhaled nitric oxide (eNO) urinary malondialdehyde (MDA) 330 32 compounds,...
