Risk management practices under the current environmental regulations is a long, complex process that considers scientific, technologic, and management factors to develop various regulatory standards and pollution control measures. Using the mandatory enforcement approach, sometimes referred to as “command-and-control”, a set of preliminary environmental goals, such as better air and water qualities, were achieved. However, the information-intensive nature of the risk management process and the lack of flexibility in conventional regulatory methods to changing economic and technologic realities of the decade has created interest among risk managers to examine some innovative management approaches. Above all, environmental problems of a global scale require novel management methods while striving to achieve the desired environmental goals. As the principal analytical tool in risk management, quantitative risk assessment exerts considerable influence on the risk management process. Therefore, advances in risk management are closely associated with scientific developments that enhance the risk assessment process, particularly those efforts aimed at improving human exposure and toxicity assessments. Market incentives, information dissemination, creative enforcement practices, and interagency and intergovernmental interactions were identified as the key elements of innovative environmental risk management practices. This paper will present an overview of the emerging innovative risk management approaches.  相似文献

为满足快速增长的电力需求,缓解传统化石能源紧缺及其所伴随的大气污染问题,发电过程中几乎不产生常规大气污染物的核电逐渐成为我国重要的能源战略选择。但是,由于核电站在运行过程中,特别是发生重大核事故时,产生的放射性物质可能对健康造成负面影响,发展核电仍然存在较大的争议和阻力。在此背景下,需要构建科学、完善的核电风险评估与管理体系,以保障我国的核电行业健康、有序发展。在对国内外核电风险评估研究现状进行系统梳理的基础上,分析其对核电风险管理的意义,提出了我国未来构建核电风险评估与管理体系的建议。  相似文献

在环境风险管理中,需要针对不同的管理目标进行评估与排序,实现有限资源供给下的风险管理效率最大化提升。作为环境风险优先管理中的一个重要内容,比较风险评价是针对不同类型环境问题进行评估与排序的方法,它可以从宏观尺度上有效识别出各类环境问题的风险大小顺序,并有针对性进行管理优先级的设置。本文在对国内外比较风险评价研究进行系统梳理的基础上,分析其对我国环境风险管理的意义,提出我国在开展环境问题的比较风险评价、建立与完善环境风险管理工作优先级等方面的建议。  相似文献

生物安全领域的环境风险包括科技风险、生态风险和环境健康风险三种类型。我国目前尚未形成健全的生物安全风险规制制度体系,科技风险规制机制不健全、生态风险规制忽视生物多样性保护、环境健康风险规制领域尚存空白等问题依然存在。为此,应确立多元化的立法目的体系,推动风险规制的类型化制度安排,有效衔接生物安全立法与环境保护法律规范,以最大限度地预防和降低生物安全风险可能带来的损害。  相似文献

The ecological systems of Earth are subjected to a wide array of environmental stresses resulting from human activities. The development of appropriate environmental protection and management policies and the appropriate allocation of resources across environmental stresses require a systematic evaluation of relative risks. The data and methodologies for comprehensive ecological risk assessment do not exist, yet we do have considerable understanding of econological stress-response relationships. A methodology is presented to utilize present knowledge for assignment of relative risks to ecological systems and human welfare from anthropogenic stresses. The resultant priorities, developed for the US Environmental Protection Agency's (EPA) relative risk reduction project, highlight global climate change, habitat alteration, stratospheric ozone depletion, and species depletion as the highest environmental risks, significantly diverging from the present emphasis by EPA and the public on toxic chemical issues. Enhanced attention to ecological issues by EPA and development of ecological risk assessment methodologies that value ecological and economic issues equitably are key recommendations.  相似文献

当前野生动物保护公益诉讼主要呈现损害控制型司法模式的特性,该模式以刑事附带民事公益诉讼为常规渠道,救济对象是既成公益损害,救济方式是损害赔偿、修复及专项整治。诉讼方式谦抑性、因果关系推定规则以及案件线索发现机制事后性,为此模式的合理运行提供了理据。本文运用风险预防原则的理论框架,认为野生动物保护公益诉讼的救济客体不应局限于生态环境损害,公共卫生安全的风险预防等关联性客体也应纳入其中,而损害控制模式这种事后治理方法存在短板。基于此,应将公益诉讼的视角回溯至事前,大力倡导风险预防型司法模式。风险预防模式与损害控制模式属于二元协同关系,前者对后者发挥补强与优化功能。根据风险预防模式的救济观,可探索野生动物保护的预防性行政公益诉讼制度,并全方位构建程序规则,以实现公益诉讼的前瞻性价值。  相似文献

在介绍美国农药环境风险评估的概念、分级、地下水农药监测情况及水资源的立法保护等基础上,重点阐述了美国环保署在农药登记管理过程中使用的2个地下水风险评估模型,即SCI-GROW和PRZM-GW模型。SCI-GROW是以好氧条件土壤半衰期和土壤有机碳分配系数为自变量的经验线性回归模型,而PRZM-GW则是描述农药在土壤中运动的一维、有限差分模型。本文通过对美国环保署这2个特点鲜明的模型的介绍,希望能为我国的农药地下水风险评估及模型的开发提供一个新视角。  相似文献

To assist risk assessors at the Department of Energy’s Savannah River Site (SRS), a Geographic Information System (GIS) application was developed to provide relevant information about specific receptor species of resident wildlife that can be used for ecological risk assessment. Information was obtained from an extensive literature review of publications and reports on vertebrate- and contaminant-related research since 1954 and linked to a GIS. Although this GIS is a useful tool for risk assessors because the data quality is high, it does not describe the species’ site-wide spatial distribution or life history, which may be crucial when developing a risk assessment. Specific receptor species on the SRS were modeled to provide an estimate of an overall distribution (probability of being in an area). Each model is a stand-alone tool consisting of algorithms independent of the GIS data layers to which it is applied and therefore is dynamic and will respond to changes such as habitat disturbances and natural succession. This paper describes this modeling process and demonstrates how these resource selection models can then be used to produce spatially explicit exposure estimates. This approach is a template for other large federal facilities to establish a framework for site-specific risk assessments that use wildlife species as endpoints.Current address: Biology Department, University of South Dakota, Vermillion, SD 57069  相似文献

Understanding toxicant effects at higher levels of biological organization continues to be a challenge in ecotoxicology and ecological risk assessment. This is due in part to a tradition in ecotoxicology of considering the direct effects of toxicants on a limited number of model test species. However, the indirect effects of toxicity may be a significant factor influencing the manner in which ecosystem structure and function respond to anthropogenic stressors. Subsequently, failure to incorporate indirect effects into risk assessment paradigms may be a significant source of uncertainty in risk estimates. The current paper addresses the importance of indirect effects in an ecotoxicological context. Laboratory, mesocosm, and whole ecosystem research into indirect effects is reviewed. The implications of indirect effects for ecological risk assessment and potential areas of profitable future research are also discussed.  相似文献
