Strategic environmental assessment in China

Journal of Environmental Science and Engineering 2008年第1期2卷 56-66页

作者： yu peng zhou jing-xuan College of Environmental Science and Engineering Huazhong University of Science and Technology Wuhan 430074 China

In the past three decades, especially in recent years, the environment has unceasingly deteriorated with rapid development of Chinese economy, and the inherent limitations of conventional project EIA have come to light. Thus, to pursue a broader course of sustainable development, the Chinese government has attached more and more importance to SEA. Strategic Environmental Assessment （SEA） is a frontier subject in the field of Environmental Impact Assessment （EIA）. This article describes the current situation of SEA in China, discusses major problems with SEA, and then recommends improvements in the system. EIA Act of the People＇s Republic of China was promulgated which explicitly provides SEA is required in regional and sector plans and programs. In order to promote comprehensive development of SEA, a lot of work has been done by SEPA. Some SEA ＂experiments＂ have been implemented, and some research has been conducted on the topic in China. But SEA as applied today in China is confronted with a host of methodological and institutional limitations. Moreover, public participation is often extremely limited, because the system restricts public participation. Policies and strategies are kept secret from the public. Most of the research has been focused on the concept, theory, and framework of SEA. Comprehensive application of SEA in China has yet to occur, and only a limited number of case studies are available. We believe SEA can be improved by the following recommendations： dividing SEA into two stages, formulating legislation to safeguard the funds for SEA, guiding actively the public to participate in SEA, completing basic data bank about SEA, and setting up Hall for Workshop of Meta-synthetic Engineering for SEA.

[Construction of a 17 β-estradiol sensor based on a magnetic graphene oxide/aptamer separating material]

Se pu = Chinese journal of chromatography 2025年第1期43卷 87-95页

作者： Xin-yu Jin Le-yuan Chen Ya-Nna Liu Wen-jing Xie Han-Yong peng State Key Laboratory of Environmental Chemistry and Ecotoxicology Research Center for Eco-Environmental Sciences Chinese Academy of Sciences Beijing 100085 China.

17-Estradiol (E2) is a natural steroidal estrogen essential for a variety of physiological functions in organisms. However, external E2, which is renowned for its potent biological effects, is also considered to be an endocrine-disrupting compound (EDC) capable of disturbing the normal operation of the endocrine system, even at nanogram-per-liter (ng/L) concentrations. Studies have revealed that medical and livestock wastewater can be contaminated with E2, which poses potential risks to human health. Currently, the primary method for detecting E2 relies on liquid chromatography-mass spectrometry, which is limited with regard to on-site or large-scale sample testing due to instrumental constraints. Herein, we developed a magnetic graphene oxide (MGO)/aptamer separating material. The MGO was synthesized by creating a water-in-oil microemulsion at 90 ℃, an agarose hydrogel to load the FeO nanoparticles, and layered graphene oxide (GO). In contrast to conventional methods, such as chemical co-precipitation and solvothermal approaches, this method is more time-efficient and does not require high temperature or pressure. Moreover, the use of a physical encapsulation technique for enwrapping the FeO nanoparticles and layered GO eliminates the need for chemical modification. This approach reduces the use of harmful chemicals, ensures complete loading, and results in highly efficient encapsulation. The MGO was characterized using Fourier-transform infrared (FT-IR) spectroscopy and transmission electron microscopy (TEM), as well as dynamic light scattering (DLS) and Zeta potential analyses, which revealed that the FeO nanoparticles had been successfully loaded onto the GO to produce MGO particles mainly around 5 μm in size. Additionally, this study demonstrated that the aqueous MGO dispersion is highly stable. This substance was used to develop a fluorescent biosensor that uses a "turn-on" mechanism to rapidly and highly sensitively detect E2. MGO is capable of adsorbing a fl

Surfactant Effects on the Permeability of Photosynthetic Membrane from Rhodobacter sphaeroides 2.4.1 Probed by Electrochromic Shift of Endogenous Carotenoids

引用

Chemical Research in Chinese Universities 2018年第6期34卷 989-994页

作者： zhou xuan yu Jie WANG peng ZHANG Jianping Department of Chemistry Renmin University of China Beijing 100872 P. R. China

Four surfactants, sodium cholate（SC）, n-dodecyl-β-D-maltopyranoside（DDM）, lauryldimethylalnine oxide（LDAO） and Triton X-100（TX）, which are generally used in photosynthetic pigment-protein complexes preparation, were studied on their interaction with photosynthetic membrane from Rhodobacter sphaeroides 2.4.1 by elec- trochromic absorption band-shift of endogenous carotenoids and by vesicle size measurements as well. The surfactant critical micelle concentration（cmc） was found to be negatively correlated with the capability of enhancing the per-meability of photosynthetic membranes to proton, and more elaborated model of snrfactants interacting with membranes was obtained. The electrochromic absorption band-shill measurement might develop into a useful tool to evaluate the effects of surfactants on various membranes.

近年来,水利水电工程中暴发了沼蛤(淡水壳菜)污损问题,不同程度地影响了水利和水电工程的输水、生产等安全,引起了国内外社会广泛关注。本文研究结果显示,沼蛤在长江流域主要分布于四川及以下的低海拔区,四川以上高海拔区未见记录;基于COI和ITS 1基因联合构建的系统发育树分析显示,长江流域沼蛤可能存在两个类群,其中COI序列A+T含量(64.7%)显著高于C+G含量(35.3%),种内遗传距离范围为0~0.123;COI序列总单倍型多样性指数为0.893,核苷酸多样性指数为0.069;ITS 1序列A+T含量为45.3%,C+G含量为54.7%,种内遗传距离范围为0~0.061;ITS 1序列总单倍型多样性指数为0.679,核苷酸多样性指数为0.028。基于COI基因分析的两个亲缘关系类群间的遗传分化系数为0.844,基因差异分化系数为0.118;基于ITS 1基因分析的相应参数分别为0.927和0.492。基于形态学特征分析显示,长江流域沼蛤的长高比、长宽比和韧带长度差异显著,可明显分成两个类群,且与COI和ITS 1基因分析显示的两个类群相对应。基于栖息生境分析显示,长江流域沼蛤类群1主要生活在水流较缓、底质以卵石为主的区域,表现为缓流型;类群2主要生活在水流较急、底质以泥沙为主的区域,表现为激流型,对环境的适应性更强,分布范围较类群1更广,在传播扩散能力方面表现更强。本研究有助于了解长江流域沼蛤基础生物学信息,可为流域沼蛤的综合防控提供重要参考。

Advances in Manufacturing 2016年第3期4卷 217-224页

作者： Wen-jing zhou Ke-Qin peng Ying-Jie yu Department of Precision Mechanical Engineering ShanghaiUniversity Shanghai 200072 P. R. China

We measure the surface roughness of the mechanical parts based on digital holography. A digital off- axis hologram recording setup for reflective samples is built. Firstly, the height reconstruction error 2.3% of the setup is calibrated by using the quartz step height standard （VLSI- SHS-880QC）. Then, the standard scribed-line model and the grinding roughness specimen are selected as the test samples and their surface roughness are 0.095 6 jam and 0.025 3 jam, with errors 6.3%, 0.9%, respectively. The results are in good agreement with the given roughness parameters. At last, we also analyze the window effect of the filter on the roughness measurement value based on digital holography. In conclu- sion, the paper demonstrated effectively that the digital holography could provide the surface feature for the rough- ness measurement with high accuracy.
