环境生物技术 meaning in Chinese
environmental biotechnology
Examples
- Application of environmental biotechnology to pollution control
环境生物技术在污染治理方面的应用 - On the basis of the investigation of the content and distribution of heavy metals in sediments and benthic organisms from the sewage stream in guangzhou city , the antagonistic effect of selenium on the harm of mercury ( hg2 + ) to the tissues in swordtail fish ( xiphophorus helleri ) , the 22nd offspring purely cultivated by pearl river fishery research institute , were measured by physiological and biochemical indexes and observation of electron microscopy
本研究中首先调查了广州市河涌沉积物及底栖生物体内重金属含量及分布，并以珠江水产研究所培育的水生实验动物?剑尾鱼为实验材料，利用环境生物技术，电镜观察等技术方法研究了重金属?汞对剑尾鱼组织的毒害及机体必需微量元素硒对其毒害的拮抗性影响。 - Abstract : by analyzing the study results on mictroorganism genetics and enzymology in the environmental biological technology over the world and the trend of the development and application of environmental biological technology in water pollution control , this paper intents to provide a reference for choosing the applied wastewater treatment technology
文摘:分析了国内外关于微生物遗传学、酶学在环境生物技术领域中的研究进展以及环境生物技术在污水治理中的开发与应用及其发展趋势，为选择实用的污水处理技术提供了参考依据。 - Using cd , cu , zn and cr as experimental toxicants and crucian as experimental creature , we employed the environmental biotechniques ( flame atomic absorption spectrophotometry , the method of improved pyrogallol autoxidation and electron microscopy ) to study the acute toxicity and secure concentrations of heavy metals to crucian ; the accumulation and distribution of mixed heavy metals to fingling crucian ; the activities of superoxide dismutase ( sod ) of gill and liver tissues and the hispathological and ultrastructural change of superfine structure of liver and kidney of crucian after cadmium exposure . through which , we intended to fully and systemically study the toxic influence of heavy metals to fish , and preliminarily discuss the influence of heavy metals pollution to the diversified level of fish such as individual , organ , tissue , cell and molecule . thus we tried to provide scientific evidence to establish preventative management measures , avoid and relieve the harm of heavy metals pollution to aquicolous ecosystem in time
随后以这几种重金属作为实验毒物，以鲫鱼为实验动物，应用环境生物技术、火焰原子吸收分光光度法、邻苯三酚自氧化法、透射电镜等技术研究了重金属cu 、 zn 、 cd和cr对鲫鱼的急性毒性及其安全浓度评价、混合重金属在鲫鱼幼体组织内的积累和分布、 cd对鲫鱼鳃和肝脏中sod活性的影响、 cd对鲫鱼肝细胞和肾细胞超微结构的影响等，全面和系统地研究了水环境中重金属暴露对鱼类的毒性影响，初步探讨了重金属污染对鱼类的个体? ?器官? ?组织? ?细胞? ?分子等各水平层次的影响，为制定渔业生产上预防性的管理措施提供科学依据，及时避免或减轻重金属污染对水生生态系统造成的损害。
