宁波市主要湖库浮游藻类调查及营养状态研究

对宁波市11个湖库水质进行了调研,包括浮游藻类和理化指标。从浮游藻类的生物量、优势种以及藻类群落组成等指标评价了水质;还用修正的营养状态指数法评价了水质。结果表明,部分湖库已经出现富营养化。用浮游藻类评价与修正的营养状态指数法评价这些湖库,结果不完全一致,对此做了原因分析。同时提出防止湖库受污染的几点建议。     

上海市陆源入海排污口污染物分析与评价研究

对上海市12个陆源入海排污口污染状况进行了研究。在常规项目监测的基础上,采用GC-MS定性分析了样品中的有毒有机物。同时还对5个排污口进行了遗传毒性的实验分析。结果表明,某些排污口常规污染指标均符合排放标准但同时又分析鉴定出大量有毒有机物存在的现象。文章对监测结果加以细致分析和评价研究,提出在排污口监测中应当引入有毒有机污染物和遗传毒性的监测。

A behavior based safety approach at a Kuwait research institution

INTRODUCTION: Behavior based safety (BBS) initiatives are the current trend toward improving safety performance. METHOD: This study outlines the framework of the BBS process and summarizes several behavioral safety approaches to accident prevention. RESULTS: Although most of the published research has focused on the improvement of safe behavior in industry, this study is the first to apply the current approach of behavior based safety in a research/educational setting. An experiment conducted at a research institution demonstrated the effectiveness of a well-designed behavior based safety process. A follow-up study indicated that the BBS produced a lasting effect for the experimental group. IMPACT ON INDUSTRY: Results from this study can be the driving force to implement behavior-based safety processes into educational, research, and training organizations.     

Ethical considerations for community-based participatory research with Sami communities in North Finland

This study examines the perspectives of Sami community members and university researchers regarding the ethical considerations for engagement in Community-Based Participatory Research (CBPR) with Sami communities in northern Finland. Key informant interviews were conducted with Sami people from Finland who were exposed to or participated in research in their communities as well as with researchers who have conducted research with the Sami in Finland across diverse topics. Five themes were identified: establishing trust, research preparation, research comprehension, research ethics, and inclusion in research. The differences in participant perspectives were compared based on their community versus researcher roles. Our findings emphasize the need for (1) strategies to develop and maintain trust between Sami communities and researchers; (2) methods to bridge concepts of bias projected onto Sami communities and researchers by the others’ differing world views and beliefs about research; and (3) increased education in community-engaged methods for social and natural scientists working with Sami communities. This study supports the need for the development of formalized ethical protocols for conducting community-based engaged research with and for Sami people in Finland that ensure mutually beneficial research for all involved.

一株好氧反硝化菌的分离及特性研究

利用富集培养的方法从城镇污水处理厂的活性污泥中分离到1株好氧反硝化菌,命名为CW。通过形态、生理生化特征和16SrRNA基因序列分析,初步鉴定为睾丸酮丛毛单胞菌(Comamonas testosteroni)。生长特性的研究表明最佳碳源是乙酸钠,最佳碳氮比10:1,最佳DO4.0～6.0mg/L,在此条件下培养24h后,对初始浓度108mg/L的硝酸盐降到27mg/L,去除率达到75%,亚硝酸盐积累仅为4mg/L。以组合载体为填料,挂膜后对污水进行处理,HRT48h,DO5.0mg/L左右,氨氮去除率达到95%左右,最终的NO3-N和NO2-N分别由起始的40～52mg/L和21～28mg/L降为--12～15mg/L和7～9mg/L。
