欧盟包装废物管理和总体产生特性分析

欧盟旱在1994年就颁布了包装和包装废物的指令,提出了包装废物管理的目标和管理内容,要求各成员国采取积极的经济和法律措施,建立自由流通的公平市场秩序。通过研究评估表明,包装和包装废物指令的实施产生了多方面的积极影响。统计数据表明,历年包装废物回收总量平稳增加,处置量平稳下降,单位GDP产值产生包装废物的系数基本保持稳定,但各国包装废物人均产生量存在较大差异。     

Optimization of the recovery of plastics for recycling by density media separation cyclones

Material recovery processes are presented as the optimum option for recycling plastic wastes as a means of recovering hydrocarbon resources. There exist a large variety of automated material recovery processes for recycling of such wastes but each with significant limitations. Of these, the separation based on differences in densities is advocated as the optimum process either for producing recycled products or preparing wastes for subsequent recovery processing.Density separation processes based on cyclone type density media separation (DMS) is presented as an important, potential method for increasing plastics recycling process capacities. It is demonstrated to have the capacity to separate a significantly larger range of particle sizes than those presently processed industrially. The mathematical relationship for the prediction of quality of typical LARCODEMS type density media separations by particle size and density as expressed by the Ecart Probable is presented.A proposed device configuration is presented for density media separation to optimize the recovery and purity of both density fractions produced. It is also suggested that to be economically viable, a large scale of operation is required for industrial plastics recycling operations recovering and producing a number of different plastics with a purity to be used as a substitute for virgin material.     

生态文明下的环境法制

生态文明建设的进程受到诸多因素的制约,如生态环境意识、环境立法、行政执法和司法缺陷、法律政策等,同时生态文明建设中面临诸多的难题,如公众参与、生态补偿、环境责任及环境纠纷等,应通过完善立法、执法及司法建设,以及完善公众参与机制、生态补偿机制、环境公益诉讼制度等保障机制来解决这些问题。本文首先通过比较分析生态文明与环境法制的关系,结合我国生态法制建设困境,提出了完善生态文明建设的一系列的环境法治保障措施,即从立法、执法、司法角度,从而实现科学发展观,构建和谐社会,最终实现环境—社会—经济协调发展的任务。     

Enhancing corporate compliance with worksite safety and health legislation

Introduction: A 2-year prospective study evaluated the effectiveness of a managerial training program to enhance corporate compliance with statewide worksite safety and health regulations. The program offered participants information about regulatory requirements and emphasized organizational and environmental strategies for reducing occupational injuries and illnesses. Objectives: To assess the effects of a train-the-trainer program on business managers' knowledge of statewide occupational safety and health legislation and on levels of corporate compliance with regulatory requirements. Methods: Forty-eight small- and medium-sized companies participated in the training sessions during the first year of the study. These firms were compared with 46 control companies that did not receive the training until the conclusion of the study. Results: Participation in the program was associated with higher levels of corporate regulatory compliance 12 months after the training sessions were held (controlling for baseline levels of corporate compliance with the regulations). Program effects on compliance levels were mediated by posttraining changes in managers' knowledge of regulatory requirements. Conclusions: The REACH OUT training program raised managers' awareness of and corporate compliance with statewide worksite safety and health regulations. Impact on Industry: Smaller companies face greater challenges than larger ones in developing and maintaining worksite safety and health programs. Barriers to regulatory compliance, especially in small- and medium-size companies, should be identified and removed to enhance the efficacy of these programs.     

化学品立法与环境保护

随着化学工业的快速发展,我国化学品的产量和贸易量呈逐年增加的趋势,因化学品所导致的环境污染也越来越严重.伴随着化学品贸易与环境管理的国际一体化趋势以及国内对环境保护的呼声越来越高,迫切要求建立、健全化学品环境管理法规.在对比分析了美国、欧盟、日本等发达国家或地区化学品立法特征的基础上,阐述了我国在化学品立法方面存在的缺陷,如预防预警、源头控制理念不足,缺乏优先管理和风险管理制度,监督管理环节薄弱,以及缺乏各部门之间协调配合的监督管理机制等;分析了我国化学品立法的必要性和紧迫性,提出了重点针对有毒有害化学物质进行管理的预防为主、源头控制、风险管理以及全过程管理的立法理念,并对立法管理对象以及需建立的管理制度和标准等主要内容提出了建议.      

我国水污染防治立法理念、机制和制度的创新

面对日益突出的水污染问题,我国现行《水污染防治法》难以适应水污染防治的要求,《水污染防治法》的修订及相关立法问题在国家立法机构、行政部门和环境法学界因而备受关注。对当前我国环境法理论界和实践部门关于水污染防治立法的观点和主张以及相关研究进展和成果进行了系统分析和整理,从为完善我国《水污染防治法》提供立法参考的目的出发,运用概括、分类和归纳的方法,对我国水污染防治立法理念、机制和制度创新进行了分析和归纳,并提出了具体的立法建议。     

Heavy Metals in Organs and Tissues of the European Black Vulture (Aegypius monachus): Dependence on Living Conditions

The distribution of Fe, Zn, Cu, Cd, Mn, Pb, and Ni in the organs and tissues (kidneys, liver, lungs, brain, heart, muscles, and feathers) of the European black vulture (Aegypius monachus) was studied. It was shown that heavy metals were not responsible for the mass mortality of these birds in southern Primorye in the winter of 2001–2002. The level of pollution with heavy metals of the range of European black vultures wintering in this region (northern China and western Mongolia) may be regarded as insignificant.     

A Report on the International Conference on Climate Policy after Marrakech: Towards Global Participation

The East-West Center convened the international conference on climate policy in Honolulu, Hawaii, on September 4–6, 2003. Sponsored by the Dutch Ministry of Housing, Spatial Planning and the Environment, the Japanese Ministry of the Environment, Industrial Technology Research Institute (Taiwan), and Institute for Global Environmental Strategies (Japan), this major event covered almost every important issue and featured perspectives from the most important parties and stakeholders in formulating and implementing climate policies and taking international climate negotiations further. It brought together a remarkable cross-section of world opinion on climate policy after Kyoto. This report provides a summary of each presentation and highlights discussions organized under the following six session headings: Session 1: Climate Change in Focus – From Science to Policy; Session 2: U.S. Climate Policy and Perspectives; Session 3: European Union Climate Policy and Perspectives; Session 4: Challenges for other Major Industrialized Countries; Session 5: Issues Related to Developing Countries; and Session 6: Panel Discussions: Where Do We Go from Here?.     

也谈对环境的损害--欧盟《预防和补救环境损害的环境责任指令》的启示

欧盟于2004年3月通过了一项预防和补救环境损害的环境责任指令,鲜明地将"环境损害"这一定义规定在该指令中,并且针对环境损害规定一系列预防和补救措施,具有较强的前瞻性.审视国内相关理论和立法,具有一定的滞后和欠缺.鉴于环境立法具有相当强的可借鉴性,围绕该指令进行相关理论和立法上的探讨.     

社会主义市场经济与环境立法

随着我国社会主义市场经济体制的逐步建立，环境立法也应随这相应发展，环境保护法制建设必要性和重要性，一是填补原有的立法空白，包括持续发展立法，环境保护组织立法环境保护行政法程序立法，二是现行环境法是一些不能与新形势相适应的内容必须加以修改完善，以排污收费为例，分析了实施中存在的问题，探讨了实行环境税的积极作用。
