危险废物处理处置技术评价方法研究

在对不同危险废物处理处置技术评价方法适用性进行分析的基础上,对危险废物处理处置技术评价方法进行了系统研究.结果发现专家评价法和环境技术评价(EnTA)法以定性评价为主,简单易行,应用范围广泛;生命周期评价(LCA)法以定量为主,但由于数据采集困难,目前在应用上还面临很多困难;层次分析(AHP)法把定性与定量评价融合得比较好,对于解决危险废物处理处置技术的选择问题行之有效.     

Changing the story? The discourse of ecological modernisation in the European Union

ABSTRACT

Over the last three decades, ecological modernisation (EM) has emerged as a powerful political discourse, in which economic growth, environmental protection and energy security are mutually reinforcing. Here, the trajectory of EM in the European Union is traced, using a discourse analysis of the seven Environmental Action Programmes. The discourse articulated in these documents points towards an encroaching ‘double depoliticisation’. First, political decisions are discursively constructed as a matter of market rationality rather than a democratic process that engages with different political positions. Second, EM is reified as the only feasible solution, and alternative and contesting discourses are marginalised. Thus not only are political differences erased from the discourse, but the discourse is itself removed from political debate.     

Conditions for successful environmental justice mobilizations: an analysis of 50 cases

ABSTRACT

The environmental justice (EJ) literature can benefit from comparative analysis that helps to identify conditions for more and less successful outcomes. A data set of 50 EJ cases in the U.S. was developed with high and low remediation as the outcome. Causal conditions were selected on theoretical grounds, and included five mobilizing strategies (local and state government coalitions, federal government attention, civil disobedience, litigation, and national NGO support) and three general conditions (absence of industry counter-mobilization, presence of water pollution, and proposed or new siting). Qualitative comparative analysis and other analyses indicated that all causal conditions were found in the high-remediation cases but that some conditions (water pollution and local–state coalitions) were more consistently associated with the high-remediation outcome. The analysis points to the value of systematic studies of the factors that affect local EJ outcomes and to the need for better case study collections.     

论我国环境侵权救济法律制度的完善

环境侵权是随着工业化和城市化的发展而出现的新型侵权行为之一。随着中国经济的迅速发展，由环境污染和生态破坏造成的环境污染侵权现象及其救济已成为中国的一大社会问题。中国目前尚缺乏对环境侵权救济法律制度的全面深入研究，有关立法也不完善，而西方发达国家有关环境侵权救济法的理论和实践已经较为成熟。拟借鉴西方国家的环境侵权救济法律制度，并立足中国国情，提出了完善中国环境侵权救济法律制度的若干建议。

宁波-舟山海域入海污染物环境容量研究

在宁波-舟山海域数值模拟潮流场的基础上,建立了该海域各污染源的响应系数场,计算了主要污染源COD、无机氮和活性磷酸盐的分担率场,及各污染源和控制单元的环境容量.研究结果将为该海域入海污染物总量控制提供科学依据.     

浙江省环境保护及相关产业现状分析及发展思路

通过对浙江省环境保护及相关产业现状的调查,基本摸清了当前全省环境保护产品、资源综合利用、环境保护服务和洁净产业等4个方面的发展情况,并从规模、地域、产业结构和效益等方面对其当前发展中存在的问题进行了全面分析,找出其发展过程中存在的问题.结合当前浙江"生态省"建设的现状,提出了浙江省环保相关产业发展的对策和思路,为决策和管理部门提供环境保护及相关产业健康快速发展的科学参考.     

中国淘汰滴滴涕的环境影响分析

目前中国仍在生产滴滴涕(DDT),并以其为原料生产三氯杀螨醇作为杀虫剂使用.为评价淘汰DDT对于中国生态环境的影响,采用情景分析的方法,估算了在采取不同的淘汰策略下土壤中DDT残留浓度的变化,以此来评价淘汰DDT的环境影响.与基线情景相比,三种控制情景下DDT的累积生产量都有不同程度的减少,相应土壤中的残留浓度也有不同的下降,且淘汰的速度越快土壤中DDT浓度下降的幅度越大.     

Photodechlorination of polychlorinated biphenyls in the presence of hydroquinone in aqueous alcoholic media

On exposure to sunlight or photolysis at λ >300nm, the dechlorination of a polychlorinated biphenyl mixture (Aroclor 1254) in the H donor alcohol 2-propanol under neutral conditions is enhanced by the presence of the photosensitizer hydroquinone. Dechlorination is strongly promoted by an increasingly aqueous solvent (1:1 water:alcohol) and by maintaining neutral conditions (pH 7.0 buffer) both in the presence and absence of sensitizer. Atmospheric oxygen (continuous aeration) retards the hydroquinone induced dechlorination less than the direct photolysis process.
