Abstract. Nitro-aromatic compounds (NACs) were measured hourly at a rural site in China during wintertime to monitor the changes due local and regional impacts of biomass burning (BB). Concurrent continuous measurements concentrations 16 NACs gas particle phases performed with time-of-flight chemical ionization mass spectrometer (CIMS) equipped Filter Inlet for Gases AEROsols (FIGAERO) unit using iodide as reagent ion. accounted <2 % concentration organic matter (OM) total particulate...
Rapid warming in the Arctic has a huge impact on global environment. Atmospheric brown carbon (BrC) is one of least understood and uncertain agents due to scarcity observations. Here, we performed direct observations atmospheric BrC quantified its light-absorbing properties during 2-month circum-Arctic cruise summer 2017. Through observation-constrained modeling, show that BrC, mainly originated from biomass burning mid- high latitudes Northern Hemisphere (∼60%), can be strong agent region,...
Abstract Organic aerosol (OA) constituted a large fraction of particles during severe haze episodes in winter northern China, yet our understanding its physical and chemical processing was limited. Here we investigate the sources processes OA four 2016 using high‐resolution mass spectrometer. The PM 2.5 reached 400 μg/m 3 severest episode (Ep1) when Beijing issued red alert implemented strict emission controls. Our results showed that secondary (SOA) dominated on average accounting for...
Epidemiological studies have consistently linked exposure to PM2.5 with adverse health effects. The oxidative potential (OP) of aerosol particles has been widely suggested as a measure their toxicity. Several acellular chemical assays are now readily employed OP; however, uncertainty remains regarding the atmospheric conditions and specific components that drive OP. A limited number simultaneously utilised multiple OP wide range concurrent measurements investigated seasonality In this work,...
Abstract. This study presents the source apportionment of PM2.5 performed by positive matrix factorization (PMF) on data presented here which were collected at urban (Institute Atmospheric Physics – IAP) and rural (Pinggu PG) sites in Beijing as part Pollution Human Health a Chinese megacity (APHH-Beijing) field campaigns. The campaigns carried out from 9 November to 11 December 2016 22 May 24 June 2017. PMF analysis included both organic inorganic species, seven-factor output provided most...
Abstract. In order to better understand the molecular composition and sources of organic aerosols in Tianjin, a coastal megacity North China, ambient fine aerosol (PM2.5) samples were collected on day/night basis from November December 2016 May June 2017. The PM2.5 components, including aliphatic lipids (n-alkanes, fatty acids, alcohols), sugar compounds, photooxidation products isoprene, monoterpene, β-caryophyllene, naphthalene, toluene, was analysed using gas chromatography–mass...
Abstract Biomass burning (BB) aerosols, primary biological aerosol particles, and secondary organic are critical components of particulate matter in the atmosphere. In this study, saccharides, lignin/resin acids, biogenic aerosols tracers, aromatic hydroxyacids/polyacids were measured total suspended particles collected from April 2012 to March 2013 at an urban site Beijing using gas chromatography/mass spectrometry. The concentration levoglucosan was elevated during 18–20 June. high ratio...
Abstract. This study investigates the seasonal variation, molecular distribution and stable carbon isotopic composition of diacids, oxocarboxylic acids α-dicarbonyls to better understand sources formation processes fine aerosols (PM2.5) in Beijing. The concentrations total dicarboxylic varied from 110 2580 ng m−3, whereas oxoacids (9.50–353 m−3) dicarbonyls (1.50–85.9 were less abundant. Oxalic acid was found be most abundant individual species, followed by succinic or occasionally...
Abstract Primary biological aerosol particles are ubiquitous in the global atmosphere and can affect cloud formation, deteriorate air quality, cause human infections. Mt. Tai (1,534 m a.s.l.) is an elevated site North China Plain where atmospheric aerosols reflect both regional advection long‐range transport. In this study, we deployed a Wideband Integrated Bioaerosol Sensor (WIBS‐4A) collected total suspended eight‐stage size‐segregated samples at summit of spring from 21 March to 8 April...
Water-soluble organic aerosol (WSOA) constitutes a large fraction of (OA) and plays an important role in affecting hygroscopicity cloud condensation nuclei formation. Here, we characterized WSOA fine particles that were collected at ground level 260 m on meteorological tower Beijing winter using offline mass spectrometry (AMS) compared them with the simultaneous real-time online AMS measurements. Our results showed increases from nonheating season to heating by 43% 53% m, respectively. was...
Online detection of bioaerosols based on the light-induced fluorescence (LIF) technique is still challenging due to complexity and external/internal mixing with nonbiological fluorescent compositions. Although many lab studies have measured properties biological materials, there a scarcity knowledge sources aerosol particles (FAP) in ambient atmosphere. Here, we fill this gap by combining online measurement an LIF-based instrument (wideband integrated bioaerosol sensor, WIBS, 0.8–20 μm)...
Summary A chemotherapy‐based mobilization regimen in patients who mobilize poorly, based on etoposide, cytarabine and pegfilgrastim (EAP), has recently been introduced. The aim of this prospective study was to investigate the efficacy safety EAP with poorly mobilizing multiple myeloma (MM) or lymphoma. This single‐arm clinical trial performed at eight public hospitals China registered as a (NCT05510089). inclusion criteria were; (1) diagnosis MM lymphoma, (2) defined ‘poor mobilizer’ (3)...
Abstract. Carbonaceous aerosol is a dominant component of fine particles in Beijing. However, it challenging to apportion its sources. Here, we applied newly developed method which combined radiocarbon (14C) with organic tracers the sources carbonaceous at an urban (IAP) and rural (PG) site PM2.5 filter samples (24 h) were collected both sites from 10 November 11 December 2016 22 May 24 June 2017. 14C was determined 25 (13 IAP 12 PG) representing low pollution haze conditions. Biomass...
The rapid advancement of large multi-modality models (LMMs) has significantly propelled the integration artificial intelligence into practical applications. Visual Question Answering (VQA) systems, which can process multi-modal data including vision, text, and audio, hold great potential for assisting Impairment (VI) community in navigating complex dynamic real-world environments. However, existing VI assistive LMMs overlook emotional needs individuals, current benchmarks lack evaluation...
The demand for ultra‐high‐definition display technology has spurred the prosperity of multiple resonance induced thermally activated delayed fluorescence (MR‐TADF) materials with narrow full‐width at half‐maximum (FWHM) and high efficiency, making them highly promising candidates high‐color‐purity organic light‐emitting diodes (OLEDs) displays. Indolocarbazole, a rigid aza‐polycyclic aromatic hydrocarbon framework, shown significant potential as building block constructing MR‐TADF emitters...
Abstract Microbes in the sea surface microlayer (SML) are key to connecting ocean and atmosphere, affecting exchange of matter, momentum, heat at interface. However, their sources have never been quantified systematically. Seawater has long deemed major source, whereas atmospheric deposition is regarded as trivial or merely providing additional nutrients. Here, combining observations quantitative budget analyses, we show that during Indonesian peatland wildfire events smoke can directly...
