Abstract A need for multi-functional assessment tools evaluating trade-offs and co-benefits various types of Nature-Based Solutions (NBS) has been increasingly identified in recent years. Methodologically, concepts a tool are presented which include quantifying the demand potential NBS to enhance ecosystem service (ES) provision, linking ESs readily quantifiable legislatively-relevant environmental quality indicators (EQIs). The objective application is identify optimal placement across...
Ambient air pollution is a major global health concern. Yet, no study has thoroughly assessed its link to respiratory mortality. Our research evaluated the combined and individual effects of pollutants on mortality risks based UK Biobank. A total 366,478 participants were studied. Cox proportional hazards model was used estimate risk from long-term exposure five pollutants, summarized as weighted score. During median 13.6 years follow-up, 6113 deaths due diseases recorded. The hazard ratios...
As the prototype Curtius rearrangement reaction, carbamoyl azide decomposes into aminoisocyanate and molecular nitrogen. However, key intermediate carbamoylnitrene was previously undetected, even though decomposition of azides has been studied frequently since its discovery in 1890s. Upon ArF laser (λ=193 nm) photolysis, stepwise two simplest H2 NC(O)N3 Me2 NC(O)N3, isolated solid noble gas matrices, occurs with formation corresponding carbamoylnitrenes NC(O)N NC(O)N. Both triplet species...
Humic acid urea fertilizer (HA-N) is a new type of slow-release nitrogenous that can enhance utilization rate urea, and consequently increases crop yield. However, there were few researches about the effect HA-N on nitrogen absorption in sweet potato production. Hence, accumulation distribution, use efficiency (NUE), yield was studied field using 15N tracer technique. Results showed significantly increased number storage roots per plant average fresh weight root, as well by 29.6% compared...
Thiophosphoryl nitrenes, R2P(S)N, are thiazirine-like intermediates that have been chemically inferred from trapping products in early solution studies. In this work, photolysis of the simplest thiophosphoryl azide, F2P(S)N3, solid noble-gas matrices enabled a first-time spectroscopic (IR and UV-vis) identification nitrene F2P(S)N its singlet ground state. Upon visible-light irradiation (≥495 nm), it converts into thionitroso isomer F2P-N═S, which can also be produced gas phase flash vacuum...
Abstract The stepwise decomposition of carbonyl diisocyanate, OC(NCO) 2 , has been studied by using IR spectroscopy in solid argon matrices at 16 K. Upon irradiation with an ArF laser ( λ =193 nm), diisocyanate split off CO and furnished a new nitrene, OCNC(O)N, its triplet ground state. Two conformers the syn anti that were derived from two (62 % – 38 ) identified characterized combining quantum chemical calculations. Subsequent visible light >395 nm) caused Curtius rearrangement nitrene...
Difluorophosphoryl azide F<sub>2</sub>P(O)N<sub>3</sub> has one dominating conformer in the gas phase at ambient temperature. It decomposes upon flash vacuum pyrolysis to hitherto unknown nitrene F<sub>2</sub>P(O)N.
Carbonyl diazide, (N3)2CO (I), is a highly explosive compound. The isolation of the substance in neat form was found to provide unique access two other high-energy molecules, namely, N3–NCO (III) and cycl-N2CO (IV), among decomposition products (I). To understand underlying reaction mechanism, reactions including thermal conversion conformers (I) were revisited, potential energy surface (PES) computationally explored by using methods B3LYP/6-311+G(3df) CBS-QB3. most stable syn–syn structure...
Both air pollution and physical inactivity contribute to the increased risk of incident chronic kidney disease (CKD). However, detrimental effects exposure could be augmented by an elevated intake pollutants during exercise. In present study, we analyzed 367,978 participants who were CKD-free at baseline (2006-2010) based on UK Biobank. Air included fine particulate matter (PM2.5 PM10), nitrogen dioxide (NO2), oxides (NOX). Physical activity (PA) was obtained self-reported questionnaire....
Methylsulfoxide radicals CH3SOx (x = 1-4) are key reactive sulfur species (RSS) in the atmospheric oxidation of volatile organic compounds (VOSCs). Through flash vacuum pyrolysis (FVP) trifluoromethanesulfinic acid methyl ester CF3S(O)OCH3 at 1000 K, methoxysulfinyl radical CH3OSO has been generated gas phase and subsequently characterized cryogenic N2, Ar, Ne matrices by IR spectroscopy. Upon 266 nm laser irradiation, efficiently isomerizes to less stable methylsulfonyl CH3SO2 without...
太湖水环境是国内外关注的焦点,其生态环境质量影响到流域经济社会发展.2007年太湖水危机事件,催生了对太湖的综合整治.本文基于2007-2016十年对太湖水质与蓝藻水华面积等的监测,分析了太湖水环境的演变趋势.太湖十年水质变化阶段性明显,2008-2012年各项水质指标下降明显,而后趋于平缓,近3年个别指标如总磷、叶绿素a浓度等呈现快速上升的反弹趋势;另外,水质指标在空间上的差异性逐步缩小,原来污染严重的西北部水域水质改善效果较为显著,其正从污水湖向自然湖状态过渡,而原来水质相对较好的东南部水域水质却逐步下降.本文也综述分析了太湖鱼类群落结构变化与水质环境变化的相关性,基于太湖局部水域的鱼类调控实践,提出了太湖现阶段以渔改水的鲢鳙控藻非经典生物操纵与鱼类结构调控的经典生物操纵结合的渔业途径.湖泊富营养化治理需要充分关注到鱼类对湖泊浮游生物和水质变化的重要驱动效应,需要充分考虑到鱼类群落结构优化和食物网调控对环境的改善作用.;Currently,water environment in the Lake Taihu has become one of focuses due to...
Sulfonyl azide isocyanate, (OCN)S(O)2N3, was prepared and characterized by IR (gas, matrix-isolation), Raman (liquid), UV-vis spectroscopy. Upon flash vacuum pyrolysis (FVP) at ca. 1000 K, gaseous (OCN)S(O)2N3 decomposes completely yields fragments N2, SO2, SO3, NCN, N3, NCO, CO, CN, NO. In contrast, the splits off N2 furnishes a transient triplet sulfonyl nitrene intermediate (OCN)S(O)2N upon 266 nm laser irradiation in solid Ne-matrix 2.8 K. Subsequent photolysis of with visible light (λ =...

UV irradiation decreases higher energy ZnNC isomer favor lower ZnCN product. Cadmium produce analogous primary molecules. Laser also produces plume radiation which initiates H‐atom detachment HCN. The freed H atom can add radical HNC isomer. matrix traps but more intensely absorbing isocyanide...
Timely short-term spatial air quality forecasting is essential for monitoring and prevention in urban agglomerations, providing a new perspective on joint pollution prevention. However, single model or correlation analysis insufficient to meet the strong demand. Thus, this paper proposed complex real-time decision-making assistance system, using hybrid module social network analysis. Firstly, before an accurate was constructed, text sentiment strategy based multiple feature selection methods...
