Abstract Recent studies have reported a variety of health consequences climate change. However, the vulnerability individuals and cities to change remains be evaluated. We project excess cause-, age-, region-, education-specific mortality attributable future high temperatures in 161 Chinese districts/counties using 28 global models (GCMs) under two representative concentration pathways (RCPs). To assess influence population ageing on projection heat-related mortality, we further age-specific...
While current research has demonstrated that the operation of some laser printers results in emission high concentrations ultrafine particles, fundamental gaps knowledge relation to emissions still remain. In particular, there have been no answers provided questions such as following: (1) What is composition particles? (2) are their formation mechanisms? (3) Why emitters, while others low? Considering widespread use and human exposure these understanding process particle critical importance....
Abstract. Over the past 10 years (2005–2014), ground-level O3 in Hong Kong has consistently increased all seasons except winter, despite yearly reduction of its precursors, i.e. nitrogen oxides (NOx = NO + NO2), total volatile organic compounds (TVOCs), and carbon monoxide (CO). To explain contradictory phenomena, an observation-based box model (OBM) coupled with CB05 mechanism was applied order to understand influence both locally produced regional transport. The simulation showed...
Abstract. Marine atmosphere is usually considered to be a clean environment, but this study indicates that the near-coast waters of South China Sea (SCS) suffer from even worse air quality than coastal cities. The analyses were based on concurrent field measurements target pollutants and meteorological parameters conducted at suburban site (Tung Chung, TC) nearby marine (Wan Shan, WS) August November 2013. observations showed levels primary significantly lower WS those TC, while ozone (O3)...
Tungsten disulfide (WS2), as a representative layered transition metal dichalcogenide (TMDC) material, possesses important potential for applications in highly sensitive sensors. Here, sensitivity-enhanced surface plasmon resonance (SPR) sensor with film modified by an overlayer of WS2 nanosheets is proposed and demonstrated. The SPR sensitivity related to the thickness overlayer, which can be tailored coating ethanol suspension different concentrations or number times repeated post-coating....
Abstract. Filter samples of fine particulate matters were collected at four sites in northern China (urban, rural, and mountain) summer winter, the contents nine nitrated phenols quantified laboratory with use ultra-high-performance liquid chromatography coupled mass spectrometry. During sampling periods, concentrations exhibited distinct temporal spatial variation. On average, total concentration urban Jinan wintertime reached 48.4 ng m−3, those summertime 9.8, 5.7, 5.9, 2.5 m−3 Jinan,...
Abstract High concentrations of organic aerosol (OA) occur in Asian countries, leading to great health burdens. Clean air actions have resulted significant emission reductions pollutants China. However, long-term nation-wide trends OA and their causes remain unknown. Here, we present both observational model evidence demonstrating widespread decreases with a greater reduction primary than secondary (SOA) China during the period 2013 2020. Most decline is attributed reduced residential fuel...
Reactive oxygen species (ROS) play an important role in atmospheric pollution, and their detection is essential for assessing air quality health risks. This study developed validated a standardized methodology using the BPEAnit probe specially designed particle-into-liquid sampler, Particle Into Nitroxide Quencher (PINQ), to measure reactive monitoring applications. The method demonstrated high sensitivity, with limit of 0.03 nmol·m-3, robust linearity (R2 = 0.9999), negligible system...
A novel strategy to modify the plasmonic interface by spin-coating an overlayer of graphene oxide sheets (GOSs) on top surface plasmon resonance (SPR) sensor is proposed and demonstrated. Thanks excellent electrical conductivity, large area, high-refractive index GOSs layer, GOSs-modified SPR (GOSs-SPR) achieves improved sensitivity in detection bulky refractive solutions bovine serum albumin (BSA) solutions. The maximum 2715.1 nm/RIU achieved three spin-coatings shows enhancement 20.2% than...
Abstract Zwitterionic polymers demonstrate as a class of antifouling materials with long blood circulation in living subjects. Despite extensive research on their abilities, the responsive zwitterionic that can change properties by mild outside signals are poorly explored. Herein, sulfamide‐based monomer is developed and used to synthesize series polysulfamide‐based (poly (2‐((2‐(methacryloyloxy)ethyl) dimethylammonio)acetyl) (phenylsulfonyl) amide (PMEDAPA)) nanogels drug carriers for...
Severe episodic air pollution blankets entire cities and regions have a profound impact on humans their activities. We compiled daily fine particle (PM2.5) data from 100 in five continents, investigated the trends of number, frequency, duration episodes, compared these with baseline trend pollution. showed that factors contributing to events are complex; however, long-term measures abate emissions all anthropogenic sources at times is also most efficient way reduce occurrence severe events....
An increasing number of researchers have hypothesized that ozone may be involved in the particle formation processes occur during printing, however no studies investigated this further. In current study, hypothesis was tested a chamber study by adding supplemental to after print job without measurable emissions. Subsequent concentration and size distribution measurements showed new particles were formed minutes addition ozone. The results demonstrated did react with printer-generated...
Abstract. To investigate the atmospheric oxidative capacity (AOC) in forested high mountain areas adjacent to photochemistry-active Pearl River Delta (PRD) region southern China, one-month online observations of isoprene and its oxidation products methyl vinyl ketone (MVK) methacrolein (MACR) were conducted at a national background station Nanling Mountains summer 2016. The results showed that observed daytime levels (377±46 pptv) significantly lower comparison with other forest sites within...
Mountainous background areas are typically considered to have a clean atmosphere where peroxyacetyl nitrate (PAN) can be decomposed. This study demonstrated that PAN was photochemically formed with simulated production rate of 0.28 ± 0.06 ppbv h–1 in the Nanling mountains (1690 m a.s.l.) South China and net formation dependent on both volatile organic compounds (VOCs) NOx precursors (transition regime). In contrast dominated acetaldehyde oxidation previous urban rural research, at primarily...
