污染场地修复工程环境监理的实践与探索   总被引:1,自引:0,他引:1  
环境监理是污染场地修复过程中不可或缺的关键环节,在我国起步相对较晚,可供借鉴的实例很少。以苏州市某化工厂遗留场地污染土壤和地下水修复工程为例,阐述了不同阶段环境监理的工作内容,突出了原位和异位修复技术的环境监理工作要点,并提出建立污染土壤和地下水修复效果质量控制体系和原位修复效果长期跟踪监测机制等建议。  相似文献

Ecological tax reform involves the utilisation of the tax system to facilitate sustainable development. The generally accepted approach to ecological tax reform is to reduce tax rates on income and labour and to impose Pigouvian taxes on resource use and pollution emissions. While this approach is a vast improvement on current tax systems, it is an inadequate means of achieving sustainable development because it relies exclusively on the manipulation of market prices – an allocation instrument – when ecological sustainability is a throughput problem that requires a separate policy instrument to be adequately resolved. With the aid of a linear throughput representation of the economic process, it is argued that conventional ecological tax reform measures promote just two of the five behavioural modes put forward to achieve sustainable development. In order to promote all five behavioural modes, it is argued that ecological tax reform is best conducted with the incorporation of tradeable resource use permits and assurance bonds.  相似文献

Improvements in human wellbeing are dependent on improving ecosystems. Such considerations are particularly pertinent for regions of high ecological, but also social and cultural importance that are facing rapid change. One such region is the Great Barrier Reef (GBR). Although the GBR has world heritage status for its ‘outstanding universal value’, little is known about resident perceptions of its values. We surveyed 1545 residents, finding that absence of visible rubbish; healthy reef fish, coral cover, and mangroves; and iconic marine species, are considered to be more important to quality of life than the jobs and incomes associated with industry (most respondents were dissatisfied with the benefits they received from industry). Highly educated females placed more importance on environmental non-use values than other respondents; less educated males and those employed in mining found non-market use-values relatively more important. Environmental non-use values emerged as the most important management priority for all.

- DOI: http://dx.doi.org/10.1065/espr2006.01.003 Background Water Quality Criteria were firstly defined in the 1970s by the EPA in the USA and the EIFAC in Europe, recognizing the need for protecting water quality in order to allow the use of water resources by man. In the 1990s, the European Commission emphasized the importance of safeguarding structure and function of biologic communities. These approaches were chemically-based. The European Water Framework Directive (WFD) substantially changes the concept of Water Quality, by assuming that a water body needs to be protected as an environmental good and not as a resource to be exploited. In this frame, the biological-ecological quality assumes a prevailing role. Main Features The Water Quality concept introduced by the WFD is a challenge for environmental sciences. Reference conditions should be defined for different typologies of water bodies and for different European ecoregions. Suitable indicators should be developed in order to quantify ecological status and to define what a 'good' ecological status is. Procedures should be developed for correlating the deviation from a good ecological to the effects of multiple stressors on function and structure of the ecosystem. The protection of biodiversity becomes a key objective. In this frame, the traditional procedures for ecotoxicological risk assessment, mainly based on laboratory testing, should be overcome by more site-specific approaches, taking into account the characteristics and the homeostatic capabilities of natural communities. In the paper an overview of the present knowledge and of the new trends in ecotoxicology to get these objectives will be given. A procedure is suggested based on the concept of Species Sensitivity Distribution (SSD). Recommendations and Perspective . The need for more site-specific and ecologically-oriented approaches in ecotoxicology is strongly recommended. The development of new tools for implementing the concept of 'Stress Ecology' has been recently proposed by van Straalen (2003). In the same time, more 'cological realism'is needed in practically applicable procedures for regulatory purposes.  相似文献
