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.     

浅谈如何做好“十一五”环境统计工作

环境统计工作存在的问题：指标体系设置不合理、数据时效性差、数据质量不高、统计人员流动性大，采取的措施：精简完善指标体系、规范工作程序和审核办法、抓好统计范围、污染源监测及数据核查提高数据质量、加强统计队伍建设等。     

内蒙古巴彦淖尔市乌拉特中旗生态环境恶化的根源及其对策

通过对乌拉特中旗近20年来农牧业生产发展情况、气象环境质量状况等多方面调查，总结出乌拉特中旗生态环境恶化的根源，按照“围封轮牧，划区禁牧，舍饲养牧，移民休牧”的指导思想，并对如何改善乌拉特中旗生态环境提出具体的对策和措施。     

MERCK公司COD试剂的替代品开发

德国MERCK公司制造的COD测定仪器在我国环保行业、科研院所的水质监测工作中应用广泛,但配套试剂价格昂贵,限制了该仪器的使用。实验设计了高量程(100～1500mg/L)和低量程(25～100mg/L)COD替代试剂的开发方案。通过实验,确定了两个量程下COD替代试剂中K2Cr2O7、H2SO4-Ag2SO4、HgSO4的浓度和投加量以及测试方法。实验结果表明,在高量程和低量程范围内,使用COD替代试剂的测试结果与MERCK公司配套试剂的测试结果比较相符,反应时间也可缩短至30min。     

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.     

A decision tree approach modelling functional group abundance in a pasture ecosystem

Decision tree, one of the data mining approaches, was used to model the relative abundance of five functional groups of plant species, namely high fertility response grasses (HFRG), low fertility tolerance grasses (LFTG), legume, moss and flatweeds in a New Zealand hill-pasture ecosystem using aboveground biomass. The model outputs were integrated with a geographic information system (GIS) to map and validate the predictions on a pasture. The decision tree models clearly revealed the interactions between the functional groups and environmental and management factors, and also indicated the relative importance of these factors in influencing the functional group abundance. Soil Olsen P was the most significant factor influencing the abundance of LFTG and moss, while soil bulk density, slope and annual P fertiliser input were the most significant factors influencing the abundance of legume, HFRG and flatweeds, respectively. Generally, slope and soil Olsen P were the two key factors underlying the patterns of abundance for these five functional groups. For the five functional groups studied, there was an overall predictive accuracy of 75%. Modelling functional group abundance simplified the investigation of the complex interrelationship between species and environment in a pasture ecosystem. The integration of the decision tree with GIS in this study provides a platform to investigate community structure and functional composition for a pasture over space, and thus can be applied as a tool in pasture management.
