“Hey Friend,Buy Green”: Social Media Use to Influence Eco-Purchasing Involvement

This study addresses the use of message carriers to convey corporate social responsibility information to promote eco-purchasing involvement. The work tests various media formats transmitted via social media. The effects of corporate vs. peer communication in a corporate social responsibility campaign in stimulating self-reported eco-purchasing involvement are indicated. The research varies communication dimensions of a fictional corporate social responsibility campaign sent through social media. Multiple media formats; new release; article; and advertisement were tested, as was the inclusion of social media persuasive sentiment. The analysis of source/format combinations and source/format/sentiment combinations found statistically significant differences for consumer-to-consumer communication in stimulating eco-purchasing involvement in certain circumstances. This research suggests an emerging role for the consumer communicator as a content co-creator and validates the effective use of articles and news releases instead of advertising on social media, yielding managerial and scholarly implications.

Perceptions toward stewardship among residents living near U.S. Department of Energy Nuclear Facilities

Although stewardship has been widely defined and used in environmental management and planning, there is a dearth of studies that describe how the lay public perceives this concept. A national sample of residents in 14 states who live near DOE nuclear facilities were interviewed to delineate public understanding and awareness of the stewardship program of the U.S. Department of Energy (DOE). This study discusses the findings of the survey and discusses how institutional trust influences public participation and resident’s choices of potential stewards. Almost 40% of the respondents could not define stewardship; those who did, believed that ‘responsibility,’ ‘management,’ and ‘accountability’ are key elements of stewardship. In addition, about a third of the respondents identified Federal groups and the DOE as potential stewards.

湘潭锰矿重金属环境安全及植物耐性研究

采集了湘潭锰矿红旗分矿开采区、沙圹村恢复区的代表性当季蔬菜(莴笋叶Fruticicolidae、小白菜Brassica chinensis、香葱Allium schoenoprasum、空心菜Ipomoea aquatica)、废弃区的优势植物(商陆Phytolacca acinosa、野茼蒿Crassocephalum crepidioides、苍耳Xanthium sibiricum)和3个研究区的土壤,通过原子吸收分光光度法分析了Mn、Pb、Zn含量。结果表明:开采区蔬菜Mn含量(8.3~84.5 mg/kg)明显高于恢复区(2.7~55.6 mg/kg),开采区和恢复区蔬菜都明显受到Pb污染(0.6~33mg/kg),蔬菜Zn含量范围为1.9~6.5mg/kg;3个研究区域土壤重金属均明显超标,最严重的是Pb污染(1 993.5~2 213.5mg/kg)。商陆、野茼蒿和苍耳中重金属含量差异较大,对重金属的耐性强,其中商陆表现出最好的耐性与长势。研究结论对锰矿土地合理利用以及矿区土壤重金属治理提供一定的科学依据。     

Forging New Directions in Science and Environmental Politics and Policy: How Can Co-operation, Deliberation and Decision be Brought Together?

Science, politics and environmental policy have for several years been encountering social and institutional as well as scientific challenges, national and international. The normative basis of all sciences is pressurised from three sides: by awareness of the public, who claims more transparency and sensibility from the scientific institutions regarding factual or possible impacts of science-based industrial progress; by the industries, which try to speed up and intensify the industrialisation of knowledge; and by the public policies, which want to see the sciences engaged in ways to mitigate unintended consequences of economic, ecological and social developments. At the same time, environmental policy is undergoing a tremendous sea change both in conceptual and practical matters. Since the Brundtland Report in 1987 and accelerated after UNCED 1992, environmental policy has been struggling to become a groundbreaking new paradigm for the capacity of resolving social and political issues as well. Any successful attempt to alter traditional institutional and mental structures in policy-making toward sustainability presupposes a renewed association of co-operation, deliberation and decision making. Results from theory of democracy, studies in science and technology, and evaluation studies in environmental policy and politics can be utilised for this context.     

在电子废弃物管理中生产者责任延伸制度探讨

随着2003年我国家电、通讯和电脑等电子产品的报废高峰期和宽带电讯业发展的黄金时代的到来，电子废弃物的污染问题日益引起人们的关注。我国传统废弃物的处理和管理制度的不完善。已使我国沿海地区的电子垃圾泛滥成灾，甚至威胁到内陆地区。而且电子废弃物中大量的有用资源没有得到有效回收。也不符合政府最近提倡的全民节约原则。因此，国家制定了有关电子废弃物的生产者责任延伸（EPR）制的具体法律法规。本文从环境经济学角度。结合其它国家和地区的生产者责任延伸制的颁布和运行情况。对我国电子废弃物的管理中施行生产责任延伸制进行初步探讨。     

我国粉煤灰生态环境标准体系现状及建议

对我国粉煤灰管理相关的现行法律法规、部门规章和文件及有关标准进行了梳理,结果显示,现行生态环境标准中尚无专门针对粉煤灰的污染环境防治技术标准,粉煤灰的环境管理中适用的是一般工业固体废物相关标准,且标准数量较少,覆盖面不全。粉煤灰在产生、收集、运输环节还缺乏污染环境防治技术标准,也缺乏针对粉煤灰各综合利用方式的污染环境防治技术标准,不利于粉煤灰的综合利用和污染防控。目前,粉煤灰生态环境标准体系需要在全过程管理环节以及促进综合利用、污染防治、风险防控、信息化建设等方面进一步完善。

     

油气田开采钻井岩屑分类利用处置现状及环境管理

油气开采过程会产生大量水基钻屑和少量油基钻屑。当前,油气田钻井岩屑大多采用不落地处理工艺进行初步收集处理。钻井岩屑通常具有较高的pH、盐离子浓度、COD和含油量（油基钻屑）等,其合理处理处置是油气田绿色发展面临的一大难题。对比分析了国内外钻井岩屑的环境管理现状,系统梳理了我国钻屑环境管理方面存在的问题。同时,基于钻井岩屑污染特性综述了其后续资源化与无害化技术的研究和应用现状,并分析了各技术优缺点和处理效果。最后,对我国钻屑利用与处置提出了“建立水基钻屑分级分类管理制度、完善钻屑利用处置过程环境管理体系和加强钻屑源头减量和末端利用”的对策建议。

规模化养猪场生命周期环境影响评价

利用生命周期评价(LCA)方法建立规模化养猪场系统能源消耗和污染物排放清单,对系统生命周期不同阶段环境影响进行评价,通过评价找出降低环境影响的方法。研究了四个环境影响类型：能源消耗、富营养化、全球变暖和环境酸化,得出各类型环境影响指数分别为8.38×10^-3,1.91×10^-3,9.80×10^-3和2.01×10^-2;将系统生命周期分成饲料原料生产、生猪饲养和废物处理三个环节,得出各环节环境影响综合指数分别为2.52×10^-2,1.23×10^-2和2.71×10^-3。结果表明,饲料原料生产环节的环境影响最大,因此,减少氮肥的使用量并在生产过程中实施节能和清洁生产,是控制规模化养猪场生命周期环境影响的关键。
