Obstructive sleep apnea syndrome (OSAS) increases the risk of post-surgery complications. This study uses Berlin Questionnaire (BQ) to identify Chinese adult surgical patients who are at a high risk of OSAS and to determine if the BQ could be used to detect potential high risk of adverse respiratory events in the post anesthesia care unit (PACU). Results indicated that only 11.4% of the patients were considered at a high risk of OSAS. Age and body mass index are the key factors for the risk of OSAS prevalence in China and also gender specific. Furthermore, the incidence of adverse respiratory events in the PACU was higher in patients with high risk of OSAS than others (6.8% vs. 0.9%, <0.001). They also stayed longer than others in the PACU (95±28 min vs. 62±19 min, <0.001). Age, high risk for OSAS, and smoking were independent risk factors for the occurrence of adverse respiratory events in the PACU. The BQ may be adopted as a screening tool for anesthesiologists in China to identify patients who are at high risk of OSAS and determine the potential risk of developing postoperative respiratory complications in the PACU.

The concept of energy internet has been gradually accepted, which can optimize the consumption of fossil energy and renewable energy resources. When wind power is integrated into the main grid, ramp events caused by stochastic wind power fluctuation may threaten the security of power systems. This paper proposes a dynamic programming method in smoothing ramp events. First, the energy internet model of wind power, pumped storage power station, and gas power station is established. Then, the optimization problem in the energy internet is transformed into a multi-stage dynamic programming problem, and the dynamic programming method proposed is applied to solve the optimization problem. Finally, the evaluation functions are introduced to evaluate pollutant emissions. The results show that the dynamic programming method proposed is effective for smoothing wind power and reducing ramp events in energy internet.

本文是近期针对华北地区霾的长期变化特征持续强霾事件发生的环境和动力条件方面研究的个结。华北地区近50 年来霾日呈现明显的上升趋势,尤其是进入21 世纪以来,霾日增加明显同时,持续性霾事件的发生频次也呈现类似的上升趋势华北地区霾污染事件频发可以归因于不利的气象环境条件和人为排放的大量污染物的共同作用。气象环境条件方面主要表现为:在气变暖的大背景下,华北地区冬季气温的持续上升、地面风速的减小以及大气稳定度的加强均对霾日的增加有显著影响。厄尔尼诺(El Nino) 年冬季,东亚大槽偏弱,冷空气活动弱,华北地区盛行异常偏南风,有利于霾天气的形成;而拉尼娜(La Nina) 年冬季,东亚大槽偏强,冷空气活动强,华北地区盛行异常偏北风,不利于霾天气的形成华北地区持续强霾事件主要发生在平直西风型和高压脊型两类环流形势下,对流层中低层为持续深厚的下沉气流,使大气边界层厚度减少污染物扩散能力减弱,有利于霾天气的维持和加剧。

首先概括极端天气气候事件以及“气候极值”的相关定义,并把极端事件分为单要素的极端事件、与天气现象有关的极端事件、多要素极端事件和极端气候事件。在此基础上,总结上述几类极端事件在气候变暖背景下的变化趋势及影响。指出气候变暖背景下我国长江中下游区域强降水事件更趋频繁,我国东部地区高温热浪天气更为明显;东北华北地区干旱趋势增加,尤其在20世纪末期和21世纪初期最为明显;近10年来西南地区干旱频繁发生。为减轻日益增加的重大气象灾害的损失,我国有必要加强高影响极端事件的监测、预警能力建设,同时还必须根据极端天气气候事件变化规律加强工程性防御措施,以防范和应对强降水引发的洪涝灾害和城市渍涝,以及与降水持续不足有关的重大干旱和高温热浪等气象灾害。
Understanding and addressing the environmental risk of microplastics
《环境科学与工程前沿(英文)》 2023年 第17卷 第1期 doi: 10.1007/s11783-023-1612-5
Over the past decades, the plastic production has been dramatically increased. Indeed, a category of small plastic particles mainly with the shapes of fragments, fibers, or spheres, called microplastics (particles smaller than 5 mm) and nanoplastics (particles smaller than 1 μm) have attracted particular attention. Because of its wide distribution in the environment and potential adverse effects to animal and human, microplastic pollution has been reported as a serious environment problem receiving increased attention in recent years. As one of the commonly detected emerging contaminants in the environment, recent evidence indicates that the concentration of microplastics show an increasing trend, for the reason that up to 12.7 million metric tons of plastic litter is released into aquatic environment from land-based sources each year. Furthermore, microplastic exposure levels of model organisms in laboratory studies are usually several orders of magnitude higher than those found in environment, and the microplastics exposure conditions are also different with those observed in the environment. Additionally, the detection of microplastics in feces indicates that they can be excreted out of the bodies of animal and human. Hence, great uncertainties might exist in microplastics exposure and health risk assessment based on current studies, which might be exaggerated. Policies reduce microplastic emission sources and hence minimize their environmental risks are determined. To promote the above policies, we must first overcome the technical obstacles of detecting microplastics in various samples.
