Effects of Bap and Cr(Ⅵ)on the Growth and Ecophysiology of Mangrove Kandelia candel Seedlings [PDF]
, 2008 在玻璃温室、自然透光下采用人工砂基栽培，研究Bap、Cr和二者的复合污染在不同浓度梯度和不同胁迫时间下，对红树植物秋茄（Kandeliacandel）幼苗的生长及生理生态效应的影响。设置Bap的系列胁迫浓度为100、200、300、400、800µg·L-1，以不加Bap为对照；Cr6+的系列胁迫浓度为0.5、2.5、5、10、25、50、100mg·L-1，以不加Cr6+为对照；Bap和Cr的复合胁迫浓度为100、200、300µg·L-1Bap分别与5、10、25mg·L ...

Vulnerability of tropical fish communities across depth in the central Indian Ocean
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Coral reefs and their fish communities below scuba diving depth (>30 m), in mesophotic coral ecosystems (MCEs) (∼30–150 m), in rariphotic (150–300 m), and in upper bathyal waters (300–500 m) are often underexplored, especially in the Indian Ocean.

Shuitu Baochi Xuebao, 2006 采用回归正交设计方案，研究了Cd、Cu、Ni复合污染对6种土壤酶（脲酶、转化酶、蛋白酶、磷酸酶、过氧化氢酶、脱氢酶）活性的影响。结果表明：6种土壤酶活性与Cd，Cu，Ni复合污染之间均呈显著或极显著的相关关系，但Cd，Cu，Ni复合污染对各种土壤酶活性的影响存在着明显差异。在复合效应影响中，重金属对土壤酶活性的抑制效应顺序为：Cd〉Cu〉Ni，Cd，Cu对土壤酶的活性多表现为抑制作用，而Ni多表现为激活作用，Cd，Cu，Ni对磷酸酶均表现出一定的激活效应。Cd，Cu ...

Ecophysiological Responses in Kandelia Obovata (S., L.) Yong and Migration and Transformation of Cadmium under Cadmium and Pyrene Combined Stress [PDF]
, 2014 红树林生态系统对维护河口和海滨生态平衡具有重要意义。近年来，大量污染物被排放到红树林湿地生态系统中，其中重金属和多环芳烃（PAHs）尤为明显。重金属和PAHs具有较强的“三致”毒性及持久性而倍受关注。本文通过盆栽实验探讨镉（Cd）与芘(Pyr)复合污染对红树植物生长的影响以及红树植物生理和解剖结构应答机制、Pyr对Cd在沉积物-植物根表-植物体内的迁移行为的影响、Cd对Pyr降解的影响，旨在丰富红树林湿地重金属-有机污染物复合污染的研究 ...

Analysis of the Response of Hepatic CYP1A in Sebastiscus marmoratus to Marine Pollution Using Loop-mediated Isothermal Amplification [PDF]
, 2014 细胞色素P450(CytochromeP450)酶系的诱导已被认为是反映环境污染状况最灵敏的生物学反应之一，其中CYP1A(CytochromeP4501A)对污染物响应敏感，可作为生物标志物反映水体受原油等有机污染物污染的情况。因此，建立一种快速简便的方法检测CYP1A对环境监测具有重要意义。 环介导等温扩增法(Loop-mediatedisothermalamplification,LAMP)是一种新型的核酸扩增技术，因具有灵敏度高、特异性强、简便、快速等优点目前已广泛应用于细菌、寄生虫 ...

Implications of Tobacco Use on Pathogen‐Driven Diseases: A Public Health and Policy Perspective
World Medical &Health Policy, Volume 17, Issue 3, Page 468-474, September 2025.ABSTRACT The tobacco epidemic remains one of the most significant global public health challenges, responsible for over 8 million deaths annually, with a substantial portion occurring among non‐smokers exposed to second‐hand smoke. While cigarette smoking remains the most prevalent form of tobacco use worldwide, the rise of electronic nicotine delivery

Shuitu Baochi Xuebao, 2006 通过盆栽实验研究了酸雨影响下紫色土Zn-Cd复合污染对莴笋的影响。结果表明：酸雨影响下，Zn为低水平时，Zn-Cd复合污染对莴笋表现为拮抗增产；Zn为高水平时，复合污染对莴笋表现为协同减产。重金属累积量在Zn-Cd复合污染时表现为Cd对Zn的作用和Zn对Cd的作用恰好相反：在Zn为低浓度时，Zn促进了莴笋对Cd的吸收，Cd抑制了莴笋对Zn的吸收；在Zn为高浓度时，Zn抑制了莴笋对Cd的吸收，Cd促进了莴笋对Zn的吸收。酸雨对莴笋的生长起抑制作用，莴笋生物量随着酸雨pH值的升高而增加 ...

Literary Reflection on Chinese Ecological Problems Inspired by Ariyosi Sawako's Report of China [PDF]
, 2014 日本当代著名女作家有吉佐和子的《有吉佐和子的中国报告》,既表达了对20世纪70年代中国生态问题的忧虑,也肯定了当时中国的一些环保举措。本文从生态批评的视角剖析作者在该报告中对中国生态问题的思考,指出有吉佐和子对生态问题的文学思考具有现实意义,其具有国际化视野的文学创作,客观上为世界生态文学的发展作出了贡献,这也是今天重读该作的重要意义所在。Ariyosi Sawako's Report of China,which was written by Ariyosi Sawako,a famous ...

Threats posed by land use to water quality in South Africa's strategic water source areas
World Water Policy, Volume 11, Issue 1, Page 155-164, February 2025.Abstract Understanding the negative impacts of land use/land cover (LULC) on water quality is key to developing effective integrated catchment management strategies. However, in line with the Integrated Water Resources Management (IWRM) philosophy, this necessitates the generation and application of useful scientific knowledge, which stakeholders and ...
