Using consequence analysis on some chlorine operation hazards and their possible effects on neighborhoods in central Taiwan

The applications of chlorine have been broadly used in many industrial products, such as bleaching agents, synthetic rubbers, plastics, disinfectants, iron chlorides, fire refractory materials, insecticides, and anti-freezers, etc. According to the Taiwan Environmental Protection Administration (TEPA), more than 30 thousand tons were used in the year 2000. In addition, there were more than 12 reported incidents from 2000 to 2003—mostly on using chlorine as disinfectants (five) and as process agents (four).

This study investigated 15 chlorine operation plants in central Taiwan. These chlorine usages included bleaching agents, disinfectants, iron chloride, synthesizing rubber plastics, and others. Thirteen plants were located in the industrial parks and two were in or near residential zones. The consequence analysis were used three different methods to analyze the worst-case scenarios (WCSs) and alternative release case scenarios (ACSs) in order to compare impact zones for applying various active and passive mitigation systems, such as confined space, scrubber, water-spray, and so no. For two plants in or near residential zones, multi-layers mitigation systems and operation limits should be implemented in order to enforce more stringent protection measures. However, there was no specific regulation for chlorine plants operated at different locations, such as industrial parks or residential zones. In order to reduce chemical accidents and their impacts on public safety, our results suggest that source mitigation/management and warning systems should be adopted simultaneously.

发展旅游对海岛环境的影响及应对策略研究

海岛作为一个独特的地理单元，旅游资源丰富，发展前景广阔，但在海岛旅游迅速发展的同时，海岛环境也受到极大的影响。而海岛又是环境敏感地区，生态环境脆弱，一旦破坏就难以恢复，所以重视海岛旅游出现的环境问题，加强对海岛环境的保护，促进海岛经济的可持续发展应引起广泛的关注和重视。     

自然生态小区建设指导原则及其建设内容探讨--以筠连县大雪山自然生态小区为例

自然生态小区是构建优美生态环境区域的生态“细胞工程”。它根据当地的自然状况和社会经济状况,以较小的经济和社会代价实现一定区域生态环境优美、生态文明有序、生态系统良性循环的社会经济生态综合体。由于自然生态小区的建设是新兴事物,其建设途径还有很多问题值得探讨。在自然生态小区建设投资方面,应当明确生态环境建设投资和生产赢利建设投资,对于前者应当以政府和政策性投资为主,而后者应当是在政策法规规范下的企业投资为主;在发展模式方面,应当促进环境友好的规模化高效益产业,包括有机绿色产业、地方特色产业、民族文化产业等;在效益分配方面,必须要充分考虑整个社区居民资源共享和利益合理分配,实现整个社区生态文明建设和经济发展目标的一致。     

新疆融雪措施对环境的影响及其防治对策

随着国民经济的飞速发展，促进和带动了城市化发展，在我国北方寒冷地区城市中，积雪对城市发展和交通安全运营的制约因素越来越受到各界人士的关注。有关部门引进并使用融雪剂去除冰雪，融雪剂在提高清除积雪效率的同时，也给城市的基础设施和生态环境带来潜在危害。为了正确合理的使用融雪剂，了解融雪剂的特性和它的融雪机理是十分必要的，在此基础上提出减轻危害的对策，为今后正确使用融雪剂提供参考依据。

Resource Use Dynamics and Land-Cover Change in Ang Nhai Village and Phou Phanang National Reserve Forest, Lao PDR

This study integrated aerial photographs from 1952, 1981, and 1998, and a satellite image from 2000 with oral histories and socioeconomic surveys to assess changes in forest and land cover in Ang Nhai village, Laos. The study documents the history of resource use and changes in household access to resources in the village. Three distinctive trends were observed in terms of forest and land cover—forest degradation, deforestation, and regeneration. Project results suggest that land and forest cover change dynamically under different circumstances. The case study also points out that integration into the market economy can induce intensification of unused lowland areas, while removing pressures from upland areas previously used for supplementing agricultural production. In addition, the creation of a national reserve forest to restrict local access and forest use was an ineffective tool for regulating encroachment and logging activities.     

Environmental Auditing and the Role of the Accountancy Profession: A Literature Review

This review of the literature on environmental auditing and the potential role of accountants distinguishes between compliance audits and audits of the environmental management system. After an extensive introduction to the concept, this review focuses on the similarities and differences between an environmental audit and a financial statement audit. The general approach to both types of audits is similar, except that environmental audits are largely unregulated. Both audits place an emphasis on the evaluation of control systems, which is an argument in favor of external auditors playing a role in environmental audits. Another argument for including external accountants is their code of ethics. However, these professionals seem to be reluctant to enter the field of environmental auditing. It is argued that this reluctance is because of a lack of generally accepted principles for conducting environmental audits. If external accountants are engaged in environmental auditing, they should be part of multidisciplinary teams that also include scientists and engineers to avoid a too strong focus on procedures. Rather than treating these audits as totally different, it is proposed that there be a move towards integrated, or even universal, audits.     

The challenges of sustainability in mining regions: The coal mining region of Santa Catarina, Brazil

Throughout history, mining communities have invariably found themselves striving for a good quality of life and a long‐term future. In the 21st century, problems of maintaining the economic vitality of mining regions are now compounded by concerns about the biophysical integrity of the local environment. In regions of the world where the economic viability of the resource is marginal and achieving a reasonable quality of life is a daily struggle, sustainable mining may seem to be a dubious prospect at best. Yet the twin imperatives of global political forces and burgeoning environmental concerns are requiring industry, governments and other interests to re‐conceptualize the way in which mining takes place in communities. Although mining itself may not be seen as an industry that contributes to the achievement of environmental objectives, it could — with careful planning — be used as a tool to foster a more sustainable and healthier community. This argument is considered in the context of the coal mining region of Santa Catarina, Brazil.
