人类社会发展到今天,创造了前所未有的文明,同时也带来了一系列环境问题。诸如废电脑、废家电、废通讯工具等废弃“电子垃圾”以及制造这砦电器过程中产生的各类废弃物占用着大量资源,对这蝼废旧电子器件和电子材料的不合理处置和回收会给环境造成极大污染。因此,广泛开展有关废旧电器和各类废旧电子材料回收利用方面的研究,使这些宝贵的二次资源得到科学合理的资源化和无害化处置,对保证人类所需生产和生活资源的永续利用,促进人类的可持续发展具有十分重要的意义。文章结合废旧电器回收利用进行了探讨。 相似文献

废荧光灯管中的有害物质如果处置不当,会对人体健康和环境造成危害。目前国内大部分废荧光灯管未得到无害化处置,主要在指定的法规、有效的政策以及完善的运营机制方面存在很多弊端,应引起社会各界的关注和政府部门的重视。本文结合国内外废荧光灯管回收处置现状,针对存在的问题,提出源头控制、分类收集、多渠道回收、建立资金及资金补贴机制以及技术手段措施,为从根本上解决废旧灯管回收难的问题,并探索社会源危险废物的管理提供对策建议。 相似文献

随着《电子废物污染环境防治管理办法》和《废弃电器电子产品处理基金征收使用管理办法》等法规的相继实施,电子废物的回收处理工作又一次成为社会关注的焦点。其中,《电子废物污染环境防治管理办法》第14条(电子电器产品、电子电气设备的生产者应当依据国家有关法律、行政法规或者规章的规定,限制或者淘汰有毒有害物质在产品或者设备中的使用……电子电器产品、电子电气设备的生产者、进口者和销售者,应当依据国家有关规定建立回收系统,回收废弃产品或者设备,并负责以环境无害化方式贮存、利用或者处置)和《废弃电器电子产品处理基金征收使用管理办法》第4条(电器电子产品生产者、进口电器电子产品的收货人或者其代理人应当按照本办法的规定履行基金缴纳义务)分别规定了电子产品生产商的回收处置责任,由此可以看出国家试图通过“生产者责任延伸制度”的贯彻来规范我国电子废物回收处理市场。 相似文献

Bangladesh is one of the most densely populated countries in the world with a very low per capita income. The increasing poverty and instability in the political front led to degradation of the environment and natural resources in the country. The present article reviews the current use of natural resources in Bangladesh and the emerging issues in sustainable management of those scarce resources. The paper shows that developments in one sector have adversely affected resources in related sectors and calls for an integrated approach to management of the environment and natural resources in a sustainable manner. The development of strong institutional mechanisms is necessary to facilitate the sustainable management of resources and to prevent further deterioration of the environment. 相似文献

Summary The author considers various moral, social and political issues that have become apparent from the aftermath of the WWF's twenty-fifth Anniversary Celebrations in Assisi, Italy. In particular, the difficulty of making people understand the very ethics of conservation, when their cultural history has shaped their minds quite differently, is highlighted, and this is reflected in the author's suggested subtitle for the paper, How to Love Nature Without Getting your Shoes Wet.But don't ever leave me alone with Nature, For I know too much about her not to be afraid (Alfred de Vigny)Maria Luisa Cohen is President of the Assisi Nature Council (See also,The Environmentalist, 5 (3) 227–229). 相似文献

The author considers the present greater awareness of the needs of the countryside brought about through public debate of the issues involved. The nature of countryside policies is considered and recent developments described. The paper concludes that much more positive planning is being undertaken to conserve the countryside, whilst allowing rural development to take place. 相似文献

Summary The need for trained technical personnel to monitor environmental systems is emphasised and detailed. Coincident with this
need is a virtual absence of appropriate training schemes. The philosophy behind and development of such a course in Farnborough
College of Technology is described. This course is a multidisciplinary Higher Diploma in Environmental Analysis and Monitoring
aimed specifically at training technicians to deal with pollution and its effects. The paper details course aims and objectives
and outlines the programme structure. As the staff at Farnborough have initiated such a training programme, we propose to
act as a resource exchange centre in this sphere. Thus our experience could aid in the curriculum development of other schemes.
Gareth Rees is Lecturer in Microbiology at Farnborough College of Technology. He has a first degree in Marine Zoology and
an M.Sc. in Biodeterioration of Materials. He has recently completed Ph.D. studies into ecological aspects of marine fungi.
At Farnborough he is leader of the Environmental Research Group, involved in several applied environmental microbiological
projects. 相似文献

This paper offers an analysis of the implementation performance of the EU Ambient Air Quality directive in the Netherlands. It provides a systematic evaluation of the implementation of a procedural provision – the obligation to design air quality policy. It draws on original data on air quality policy measures that have been collected in 13 medium-sized Dutch municipalities. The analysis of differences in the implementation performance was performed using a novel three-dimensional conceptual framework. The findings illustrate great differences in the implementation performance between the municipalities. The focused comparison allowed establishing very precisely where the implementation performance is poor or even lacking, and which municipalities take their EU implementation task more seriously than others. Most puzzling, environmental problem pressure turned out not to act as a sufficient trigger for municipalities to take far-reaching air quality measures. In contrast to previous research, a more nuanced picture is painted when it comes to the concepts of ‘compliance’, ‘non-compliance’ and ‘over-compliance’. A careful dissection of the implementation performance based on the aspects of the conceptual framework produces hands-on recommendations to municipalities seeking to improve their air quality policy. 相似文献

This article compares non-fuel mineral exploration in the USSR and the USA. It examines the organization of exploration; recent trends in the level and distribution of expenditures; exploration productivity; and planning and decision making. It shows that although the sequence of exploration stages and activities is very similar in both countries, substantial differences overshadow these similarities, largely because of different economic and political systems and mineral endowments. However, the article concludes that we still have much to learn before making a full comparison of Soviet and US exploration. 相似文献
