Abstract. Ambient nitrate has been of increasing concern in PM2.5, while there are still large uncertainties quantifying the formation aerosol. The pathways aerosol at an urban site and a suburban Pearl River Delta (PRD) investigated using observation-constrained box model. Throughout campaigns, pollution episodes were constantly accompanied with increase concentrations fractions both sites. simulations demonstrate that chemical reactions daytime night contributed significantly to boundary...
Abstract The removal of cupric ions from aqueous solution by a biosorption column in which the Rhizopus arrhizus fungal biomass was immobilized reticulated foam support particles studied. Solution pH found to be crucial copper uptake, with optimum range being 6·7–7·0. efficiency usually higher at low influent concentration and long residence time. presence other cations anions inhibited uptake following order: for cations, Mn 2+ ≫ Zn > Cd Mg Ca ; anions, EDTA SO Cl − . process fully...
Negligible losses were observed for many atmospheric trace species after traversing the PFA Teflon tubing that was hundreds of meters in length.
We have systematically examined the gas and particle phase emissions from seven wood combustion devices. Among total carbon mass emitted (excluding CO2), CO were dominant, together with nonmethane volatile organic compounds (NMVOCs) (10–40%). Automated devices 1–3 orders of magnitude lower CH4 (0.002–0.60 g kg–1 wood) NMVOCs (0.01–1 compared to batch-operated (CH4: 0.25–2.80 wood; NMVOCs: 2.5–19 wood). 60–90% in starting devices, except for first load cycles. Partial-load conditions or...
Abstract. Reactive oxygen species (ROS) are believed to contribute the adverse health effects of aerosols. This may happen by inhaled particle-bound (exogenic) ROS (PB-ROS) or formed within respiratory tract certain aerosol components (endogenic ROS). We investigated chemical composition aerosols and their exogenic content at two contrasting locations Beijing (China) Bern (Switzerland). apportioned ambient organic different sources attributed observed water-soluble PB-ROS them. The...
Abstract. Current process-based research mainly uses box models to evaluate photochemical ozone production and destruction rates, it is unclear what extent the reaction mechanisms are elucidated. Here, we modified improved a net rate (NPOPR, P(O3)net) detection system based on current dual-channel chamber technique, which makes instrument applicable different ambient environments, its various operating indicators were characterized, i.e., “airtightness”, light transmittance, wall losses of...
Abstract. Inhalation of atmospheric particles is linked to human diseases. Reactive oxygen species (ROS) present in these aerosols may play an important role. However, the ROS content and their formation pathways are still largely unknown. Here, we have developed online offline analyzer using a 2′,7′-dichlorofluorescin (DCFH) based assay. The was calibrated with H2O2 its sensitivity characterized suite model organic compounds. instrument detection limit determined as 3 times noise 1.3 nmol...
The Changjiang Estuary and its adjacent East China Sea are among the largest coastal hypoxic sites in world. oxygen depletion near-bottom waters (e.g., meters above seabed) off is caused by water column respiration (WCR) sedimentary (SOR). It essential to quantify contributions of WCR SOR total apparent utilization (AOU) understand occurrence hypoxia Estuary. In this work, we analyzed δ 18 O 2 /Ar values marine dissolved gas samples collected during a field investigation July 2018. We...
Two new sweet oleanene-type triterpene oligoglycosides, named apioglycyrrhizin and araboglycyrrhizin, were isolated from the air-drie root of Glycyrrhiza inflata [Chinese Glycyrrhizae Radix, Shinkyo-kanzo in Japanese], their structures have been determined on basis chemical physicochemical evidence.
Three new saponins, named notoginsenosides-R3 (11), -R4 (12), and -R6 (13) were isolated from Sanchi-Ginseng, roots of Panax notoginseng. The structures these saponins established as 20 (S)-protopanaxatriol 6-O-β-D-glucopyranosyl-20-O-β-D-glucopyranosyl (1→6)-β-D-glucopyranoside (S)-protopanaxadiol 3- [O-β-D-glucopyranosyl (1→2)-β-D-glucopyranosyl]-20-O-β-D-xylopyranosyl (1→6)-β-D-glucopyranosyl 6-O-β-D-glucopyranosyl-20-O-α-D-glucopyranosyl (13), respectively. Besides two known...
Abstract. Wood combustion emissions can induce oxidative stress in the human respiratory tract by reactive oxygen species (ROS) aerosol particles, which are emitted either directly or formed through oxidation atmosphere. To improve our understanding of particle-bound ROS (PB-ROS) generation potential wood emissions, a suite smog chamber (SC) and mass (PAM) experiments were conducted under well-determined conditions for different devices technologies, fuel types, operation methods, regimes,...
This paper describes the matrix effect during analysis of ten antibiotic compounds in water by SPE followed HPLC‐ESI‐MS/MS. The target analytes were tetracycline, oxytetracycline (tetracyclines), sulfathiazole, sulfamethazine, sulfadiazine (sulfonamides), erythromycin‐H 2 O, roxithromycine, spiramycin (macrolides), ofloxacin, and norfloxacin (quinolones). was examined for internal standards five different matrixes, with signal suppression being increased order: ultrapure water, tap river...
Abstract. HO2 uptake kinetics onto ambient aerosols play pivotal roles in tropospheric chemistry but are not fully understood. Field measurements of aerosol chemical and physical properties should be linked to molecular-level kinetics; however, given that the reactivity is low, traditional analytical techniques unable achieve this goal. We developed an online approach precisely investigate lower-limit values (i) reactivities gases (ii) coefficients (γ) during 2019 Air QUAlity Study (AQUAS)...
