东海区小黄鱼总允许渔获量初探

根据1991~2003年中国渔业统计年鉴以及东海区渔业资源动态监测网各网站监测产量和捕捞努力量(投网次数)数据,通过同时期东海区小黄鱼产量对海区总捕捞努力量进行标准化,运用剩余产量模型中的Fox模型估算东海区小黄鱼最大持续产量(MS Y)、最适产量(Y0.1)和总允许渔获量(TAC)。结果表明,东海区小黄鱼的最大持续产量为116 565 t,相应捕捞努力量(fMSY)为4 988 315网次,最适产量为113 068 t,相应捕捞努力量(f0.1)为3 890 886网次,TACMSY=99 317 t,TAC0.1=77 468 t。建议以东海区小黄鱼总允许渔获量(TAC0.1)作为渔获量限额指标,对小黄鱼的总允许渔获量进行管理。     

危险废物处理处置技术评价方法研究

在对不同危险废物处理处置技术评价方法适用性进行分析的基础上,对危险废物处理处置技术评价方法进行了系统研究.结果发现专家评价法和环境技术评价(EnTA)法以定性评价为主,简单易行,应用范围广泛;生命周期评价(LCA)法以定量为主,但由于数据采集困难,目前在应用上还面临很多困难;层次分析(AHP)法把定性与定量评价融合得比较好,对于解决危险废物处理处置技术的选择问题行之有效.     

Heterogeneous water phase catalysis as an environmental application: a review

Catalytic water phase processes as an environmental application is a relatively novel subject with tremendous potential in the near future. This review of 120 references presents the wide scale of heterogeneous water phase applications studied mainly within past five years. Both oxidation and hydrogenation processes are included as well as TiO₂ assisted photocatalysis. According to the references, heterogeneous catalysis is developing rapidly. New bimetallic catalysts and supports with higher surface area have improved catalytic efficiency in both oxidation and hydrogenation processes. It also seems that study on use of some waste materials such as red mud as catalyst is a very progressive field. On the whole, the chemical aspects are pretty well known, but the catalyst durability, and in many cases activity as well, has to be improved.     

华北山区环境综合整治与生态建设

华北山区位于华北平原与陕甘黄土高原以及内蒙古高原之间，是我国经济欠发达地区之一。它又是我国华北平原、京津唐等大城市工农业和生活用水的主要源地，生态环境类型复杂多样，但由于人类活动频繁，自然植被破坏严重，生态系统结构紊乱，功能脆弱，自身恢复能力较弱。积极开展华北山区的环境综合整治与生态建设不仅对解决当地人民的生活和生存问题具有重要的意义，而且对于我国华北地区经济的发展也具有重要的战略意义。本文详细分析了华北山区的生态系统特点和存在的问题，并在此基础上提出在该区环境综合整治与生态建设的具体措施和途径。     

海洋环境污染监测方案设计研究

海洋环境污染监测方案是一项复杂的系统工程。中国经过２０多年海洋环境污好监测的实践活动，积累了丰富的经验。但是，由于未能对海洋环境污染监测方案进行深入细致的研讨，致使今天我国海洋环境污染监测尚停留在定性或半定量描述阶段。该文第一次把有关海洋环境污染监测相结合，通过运用逻辑构思方法和监测方法学，详细分析监测方案设计中的各个阶段，监测目标的提出，到方案的实施；从监测数据的加工，到监测信息的发布都进行了辩证的分析。本文既是中国海洋环境污染监测方案的设计指南，也是中国海洋环境污染监测工作的集大成。     

Changing the story? The discourse of ecological modernisation in the European Union

ABSTRACT

Over the last three decades, ecological modernisation (EM) has emerged as a powerful political discourse, in which economic growth, environmental protection and energy security are mutually reinforcing. Here, the trajectory of EM in the European Union is traced, using a discourse analysis of the seven Environmental Action Programmes. The discourse articulated in these documents points towards an encroaching ‘double depoliticisation’. First, political decisions are discursively constructed as a matter of market rationality rather than a democratic process that engages with different political positions. Second, EM is reified as the only feasible solution, and alternative and contesting discourses are marginalised. Thus not only are political differences erased from the discourse, but the discourse is itself removed from political debate.     

Conditions for successful environmental justice mobilizations: an analysis of 50 cases

ABSTRACT

The environmental justice (EJ) literature can benefit from comparative analysis that helps to identify conditions for more and less successful outcomes. A data set of 50 EJ cases in the U.S. was developed with high and low remediation as the outcome. Causal conditions were selected on theoretical grounds, and included five mobilizing strategies (local and state government coalitions, federal government attention, civil disobedience, litigation, and national NGO support) and three general conditions (absence of industry counter-mobilization, presence of water pollution, and proposed or new siting). Qualitative comparative analysis and other analyses indicated that all causal conditions were found in the high-remediation cases but that some conditions (water pollution and local–state coalitions) were more consistently associated with the high-remediation outcome. The analysis points to the value of systematic studies of the factors that affect local EJ outcomes and to the need for better case study collections.     

Ein Indikator für den Einsatz gef?hrlicher Stoffe in Produkten und Prozessen: Monoethylenglykol-?quivalente

Zusammenfassung  Zur Quantifizierung des Gefahrstoffeinsatzes in der Produktion ist im Rahmen der integrierten ?kologischen Bewertung des ?ko-Institutes (EcoGrade) eine eigene Methodik entwickelt worden. Indikator für den Gefahrstoffeinsatz sind Monoethylenglykol (‘MEG’)-?quivalente. Sie erm?glichen einen direkten, schadstoffbezogenen Prozess- und Produktvergleich (Bunke 2001). Die Bewertung basiert auf den R-S?tzen (Gefahrenhinweise) der Inhaltsstoffe. Die Methodik der MEG-?quivalente stellt eine Weiterentwicklung und Anwendung des Wirkfaktorenmodells der Technischen Regel für Gefahrstoffe (TRGS) 440 dar (AGS 2001). Die zur Bewertung erforderlichen Daten sind im Unternehmen vorhanden (Sicherheitsdatenbl?tter) bzw. ?ffentlich leicht zug?nglich (Gefahrstoffdatenbanken). Die Bilanzierung von Gefahrstoffen mit Hilfe der hier vorgestellten Methode erm?glicht es auch, in ?kobilanziellen Untersuchungen systematisch den Gefahrstoffeinsatz zu berücksichtigen. Die Methodik ist am Beispiel von Wohngeb?uden erprobt worden. Anmerkung: Als Gefahrstoffe, Schadstoffe, gef?hrliche Inhaltsstoffe bzw. gef?hrliche Stoffe werden in dieser Arbeit solche Stoffe definiert, die eines der Gef?hrlichkeitsmerkmale nach § 3 Chemikaliengesetz besitzen.
