The concentrations of eight organophosphate esters (OPEs) have been investigated in air, snow and seawater samples collected during the cruise ARK-XXVIII/2 from sixth June to third July 2014 across North Atlantic Arctic. sum gaseous particle (ΣOPE) ranged 35 343 pg/m3. three chlorinated OPEs accounted for 88 ± 5% ΣOPE. most abundant OPE was tris(2-chloroethyl) phosphate (TCEP), with ranging 30 227 pg/m3, followed by major OPEs, such as tris(1-chloro-2-propyl) (TCPP, 0.8 82 pg/m3),...
Nine organophosphate esters (OPEs) were investigated in air samples collected over the Bohai and Yellow Seas (East Asia) during a research cruise between June 28 July 13, 2016. These same OPEs quantified at site (North Huangcheng Island, NHI) middle of Strait from May 16, 2015, to March 21, The median total OPE (ΣOPE) concentration was 280 pg/m3. Tris(1-chloro-2-propyl) (TCPP) most abundant OPE, followed by tris(2-chloroethyl) phosphate (TCEP), tri-iso-butyl (TiBP), tri-n-butyl (TnBP)....
Incomplete understanding of the sources secondary organic aerosol (SOA) leads to large uncertainty in both air quality management and climate change assessment. Chemical reactions occurring atmospheric aqueous phase represent an important source SOA mass, yet, effects anthropogenic emissions on (aqSOA) are not well constrained. Here we use compound-specific dual-carbon isotopic fingerprints (δ13C Δ14C) dominant aqSOA molecules, such as oxalic acid, track precursor formation mechanisms aqSOA....
This paper develops a conceptual model and an indicator system for measuring economic resilience of resource-based cities based on the theory evolutionary related concepts persistence, adaptation, transformation. Nineteen resource- in Northeast China were analyzed using system. The results showed that Liaoning Jilin provinces had higher than Heilongjiang Province. Panjin, Benxi, Anshan Province top three cities, while Shuangyashan other coal-based ranked last. Metals- petroleum-based...
Polycyclic aromatic hydrocarbons (PAH) are produced from incomplete combustion of organic matter and released as environmental contaminants activities such transports, wood combustion, coal-fired power plants. In numerous urban areas worldwide, the levels PAH exposure considered critical regarding public health issues. The possibility to detect metabolites biologically incorporated in human hair was demonstrated proposed biomarkers exposure. Nevertheless, distinguish different between...
The high use of pesticides worldwide and the constant exposure humans to these toxic-by-design chemicals have drawn attention on possible consequences human health. However, information general population remain very limited in most countries, especially urban areas. In present work, hair analysis was conducted investigate 204 women living two Chinese cities (Baoding Dalian) 110 30 metabolites following families: organochlorines, organophosphates, carbamates, pyrethroids, neonicotinoids,...
As with the fast advances in technologies of big Earth data and information communication, Web-based 3D GIS system has come a long way from few years ago. These reflect many aspects such as higher real-time performance, enhanced interactivity, more realistic visualization effect improved user interface. This paper aims to present comprehensive up-to-date Web for Emergency Response using current vue.js web application framework well-known Cesium API, taking landslide disaster an example....
The inherent physico-chemical properties of commercial konjac powders often limited their application across various industries. While existing modification techniques had produced with diverse physical attributes, these methods were frequently associated high costs and environmental concerns. Hence, there was a critical need to develop cost-effective, environmentally friendly, straightforward method for modifying powders. This study investigated the effects moisture combined drying on key...
Although organochlorine pesticides (OCPs) have been banned for more than three decades, their concentrations only decreased gradually. This may be largely attributable to environmental persistence, illegal application, and exemption usage. study assessed the historic current regional context dichlorodiphenyltrichloroethane (DDT), chlordane, hexachlorobenzene (HCB), which were added Stockholm Convention in 2001. An air sampling campaign was carried out 2018 nine cities of Pearl River Delta...
An investigation of permafrost in the Gaize area west Qinghai—Tibet Plateau China was conducted October and November 2010 2011. It found that mean annual ground temperature >−1 °C with a thickness <60 m widespread alpine steppe below an altitude 5400 a.s.l. The active layer usually deeper than 3 maximum about 5.7 m. Overall, ice/water content top 15 frozen soil <10%. altitudinal limit 5100, 5000, 4950 on south-, east-west-, north-facing slopes, respectively. A map constructed using ARCGIS...
The concentrations of 16 polycyclic aromatic hydrocarbons (∑ 16PAHs) were measured by gas chromatography equipped with a mass spectrometry detector (GC-MS) in 56 topsoil samples around Guanting Reservior (GTR), which is an important water source for Beijing. Low to medium levels PAH contamination (mean=394.2±580.7 ng g−1 dry weight (d.w.)) was evident throughout the region. In addition, localised areas high near steel and cement factories identified, ∑ 16PAHs as 4110 ng/g, (d.w.). There...
A nonoverlapping domain decomposition algorithm is proposed to solve the linear system arising from mixed finite element approximation of incompressible Stokes equations. continuous space for pressure used. In algorithm, Lagrange multipliers are used enforce continuity velocity component across subdomain boundary. The enforced in primal form, i.e., neighboring subdomains share same degrees freedom on interface and no needed. After eliminating all variables independent interior parts...
Quasiclassical trajectories have been run for the title atmospheric reaction over range of temperatures 5 ≤ T/K 3000 on a recently proposed single-sheeted double many-body expansion (DMBE) potential energy surface ground-state N2O((1)A'). As typical in capture-like reaction, rate constant decreases with temperature 50 800 K, while showing small dependence at higher regimes. At room temperature, it is predicted to value (20.1 ± 0.2) × 10(-12) cm(3) s(-1). The calculated cross sections show...
