Stormwater runoff at airports is a significant and costly issue, especially for the stormwater laden with deicing contaminants of high Biochemical Oxygen Demand （BOD） and aquatic toxicity. To reduce the loading of deicing constituents in stormwater and to manage the increasing pressure of tightening regulations, identifying fate and transport and evaluating environmental risks of deicing stormwater are of critical importance. In this review, the regulatory development of airport deicing stormwater management was first discussed, along with the milestone Airport Cooperative Research Program （ACRP） Report 14 publication. The deicer usage and fugitive losses can be reduced and the amount of deicer collected can be increased by having a better understanding of the fate and transport of deicing constituents in stormwater. As such, an overview and evaluation of the constituents of concern in deicers were provided to support the assessment of environmental impacts and mitigation recommendations. The state of knowledge of airport deicing stormwater management was then reviewed, which needs to be synthesized into a national guidance document. A guidebook and a decision tool for airports were proposed to adopt specific practical stormwater management strategies while balancing their priorities in environmental, economic, and social values against operational constraints. These challenges pose great opportunities to improve the current practices of airport deicing stormwater management.

While fire is an inherent part of the Australian landscape,the bushfires that occurred in eastern Australia from September 2019 to early February 2020 were unprecedented(Figure 1).Bushfires across the nation burned more than 12.6 million hectares(an area slightly bigger than Belgium,Denmark,and the Netherlands combined),emitted about 430 tonnes of carbon dioxide into the atmosphere(about three-quarters of the country's total annual carbon dioxide emissions),directly caused at least 33 deaths and over one billion animals were killed(https://***/news/science/2020-03-05/bushfire-crisis-five-big-numbers/12007716).

Aims Invasive species often have higher relative growth rates(RGR)than their native *** use efficiency,total leaf area and specific leaf area(SLA)are traits that may confer RGR differences between natives and invasives,but trait differences are less prominent when the invasive species belongs to the same plant functional type as the dominant native ***,we test if traits displayed soon after germination confer an early size ***,we predicted that invasive species seedlings grow faster than the natives because they lack trade-offs that more strongly constrain the growth of native *** We quantified plant morphological and physiological traits and RGR during early seedling growth at high and low nutrient levels in three dominant perennial native C_(4) grasses:Panicum virgatum L.(switchgrass),Schizachyrium scoparium(Michx.)Nash(little bluestem)and Andropogon gerardii Vitman(big bluestem);and a perennial C_(4) exotic invasive grass,Sorghum halepense(L.)Pers.(Johnsongrass).Important Findings After 2 weeks of growth,Johnsongrass seedlings had greater biomass,SLA and photosynthetic nitrogen use efficiency,but lower leaf N concentrations(%leaf N)and root:shoot ratio than *** growth continued,Johnsongrass more quickly produced larger and thicker leaves than the natives,which dampened the growth advantage past the first 2 to 3 weeks of *** in carbon gain appears to be the best explanation for the early growth advantage of *** natives,growth was constrained by an apparent trade-off between allocation to root biomass,which reduced SLA,and production of leaves with high N content,which increased carbon *** Johnsongrass,root:shoot ratio did not interact with other traits,and%leaf N was decoupled from RGR as a result of a trade-off between the positive indirect association of%leaf N with RGR and the negative direct association of%leaf N with RGR.

目的探索血红素氧合酶(HO-1)对体内血栓形成的调节功能,并探求其可能机制。方法基因敲除技术培育出C57BL/6J HO-1杂合小鼠(HO-1+/-),在杂合小鼠子代中用PCR方法筛选出同代野生型小鼠(Wt)以及基因缺失型小鼠(HO-1-/-);用FeCl3刺激鼠颈动脉并记录栓塞时间;Western blot及化学法确定实验动物血小板HO-1、环状一磷酸鸟苷(cGMP)表达水平,并用常规方法检测血小板聚集率。结果Wt小鼠的平均栓塞时间为(15.56±1.25)min,HO-1-/-小鼠为(12.85±0.55)min,差异无统计学意义(n=14,P>0.05)。经氧化血红素预刺激后,Wt小鼠的栓塞时间[(16.25±1.20)min]与HO-1-/-小鼠[(11.96±0.98)min]相比显著延长(P<0.05)。同时,连续3d的氧化血红素注射,可使Wt小鼠血小板中HO-1的蛋白表达提高约4倍;腺苷二磷酸(ADP)诱导的血小板聚集在Wt小鼠中出现显著降低;Wt小鼠与HO-1-/-小鼠血小板相比cGMP水平可被氧化血红素显著上调。结论在HO-1表达升高的应激条件下,血小板性血栓的形成受到抑制,此作用依赖于体内HO-1的存在,并与cGMP有关。

Since economic reforms began in 1978, China＇s urban population has increased by half a billion. Over the next 20years, cities will likely add another 300 million people through local population growth, migration and the integration of nearby rural areas, Cities account for the majority of resource use and pollution so achieving greener growth will depend on developing and implementing a more sustainable urbanization model. China＇s leaders have responded to these challenges with ambitious goals and comprehensive environmental laws and regulations. These have so far not significantly reduced the harm from air, water and soil pollution.＂ in large measure because China ＂s green governance does not match its green ambitions. Drawing on the World Bank ＇s work on green growth and a recent joint urbanization study by the Development Research Center of China＇s State Council and the Worm Bank, this paper reviews recent academic research on green governance in urban China and discusses its main implications in the context of emerging global green growth concepts.
