Opportunities and constraints for Product-oriented Environmental Management Systems (P-EMS)

Product-oriented Environmental Management Systems (P-EMS) are a logical extension of current, often primarily process- of facility-oriented Environmental Management Systems. The Dutch government promotes P-EMS as part of its product-oriented environmental policies. The idea of P-EMS is to enable producers to make environmentally responsible decisions on product development and product strategies, in collaboration with suppliers and customers. This paper summarises example P-EMS projects in The Netherlands for two segments of industry, namely retail and manufacturing industry. Moreover two other initiatives will be covered that deal with the development of tools to facilitate P-EMS in two other industry sectors (food processing and building). Success factors that emerge from these initial experiences are: focus on partners that have a strong incentive to act, application of screening Life Cycle Assessments (LCA) or user-shells for LCA, and focus on improvements that can be implemented on the short term.     

建立上海市突发环境事件应急防范和处置体系的研究

随着人类活动的加剧和工业的不断发展，全球突发环境事件日渐频繁。因此，在日常工作中应加强突发环境事件的应急防范和反应体系建设。防患于未然。文章概述了国内外对突发环境事件的防范及应急处置现状，分析了突发环境事件的特点和危害，简要阐述了建立上海市突发环境事件应急处置指挥系统的重要性及必要性，重点介绍了上海市突发环境事件的应急指挥、应急响应及灾害评估体系，并介绍了与突发环境事件应急处置有关的几个问题。以增加系统的可操作性。同时。提出了加强上海市应急防范和处置系统建设的对策及建议。     

城市供水管网漏损控制潜力研究

在我国各城市普遍缺水的同时，城市供水管网的漏损状况却相当的严重，科学衡量漏损控制的潜力，对于控制漏损和科学地进行城市水资源规划和需求管理非常重要。从技术潜力、经济潜力、社会潜力三方面将城市供水管网漏损控制的潜力进行了分析。提出了以社会最优值作为漏损控制的目标，以社会潜力作为需求管理的依据，同时综合考虑技术潜力和经济潜力。社会最优控制水平和企业的经济漏损控制水平之间有时会存在很大差异。科学的划分政府和企业在控制漏损的义务是非常必要的，如果需要企业的漏损控制水平小于经济漏损水平时政府应该给予一定的补偿，这样才能增加企业控制管网漏损的积极性。     

A review of EMAS in Greece: is it effective?

EMAS certification is a common practice among the European companies. However, based on the data from the Greek Ministry of Environment, only 10 companies were EMAS certified in Greece by December 2003. The aim of this study is to identify and summarize the experiences of the EMAS certified companies that operate in Greece. Based on the results of the study, the major advantage from the EMAS implementation seems to be the closer monitoring of the production process while the main cost item is the infrastructure upgrading.

Fluoride distibution and the effect of some ions along Alexandria coastal Mediterranean seawater of Egypt

The coastal seawater of Mediterranean of Alexandria receives large amount of discharged waters containing industrial wastes, sewage, and agricultural and domestic drainage. Fluoride and some parameters were(chemical and physical) determined. The data gave indication that the content and the amount of the discharged water largely affect the chemical composition of the coastal water. Stepwise regression analysis was highly significant and the model was very fruitful, where the observed and calculated values were mostly concordant. This may indicated that there was a relation between fluoride content in coastal seawater and its content in the discharged water.     

世行贷款昆明滇池流域管理项目效益分析

滇池流域环境管理项目主要是针对控制或削减磷的入湖负荷及其人它如ＣＯＤ，ＢＯＤ，悬浮物，氮等污染负荷而设置的。应用针对滇池对海磷负荷－水质响应的数学模型可以预测此项目的直观效益。即项目实施后，可以避免滇池水质的继续恶化，保持其原有功能，虽然水质的磷指标仍将维持现在的水平，但ＣＯＤ，总氮等污染物可望有一定程度的消减。
