汽车尾气中有害气体的来源与防治措施 总被引:4,自引:0,他引:4
ResourceandTreatmentMeasuresfortheToxicEmissionofAutomobiles在发达的工业化国家中,汽车尾气(即汽车排出的废气)是构成大气污染的主要原因。例如在美国,汽车排放的一氧化碳占美国一氧化碳排放总量的66%,碳氧化合物占48%,氮氧化合物占40%。我国近几年来汽车产量猛增,保有量近二千万辆左右,年生产量也是140万辆左右,到2000年可突破保有量2000万辆,年生产量可达250万辆。如果我们不注意和采用有效的办法来控制汽车尾气的排污量,届时将会对大气形成极大的危害。一、汽车尾气中有客气体产生的来源汽车有害气体从下述的不同… 相似文献

Risk Management of Sediment Stress: A Framework for Sediment Risk Management Research 总被引:1,自引:0,他引:1
Research related to the ecological risk management of sediment stress in watersheds is placed under a common conceptual framework in order to help promote the timely advance of decision support methods for aquatic resource managers and watershed-level planning. The proposed risk management research program relies heavily on model development and verification, and should be applied under an adaptive management approach. The framework is centered on using best management practices (BMPs), including eco-restoration. It is designed to encourage the development of numerical representations of the performance of these management options, the integration of this information into sediment transport simulation models that account for uncertainty in both input and output, and would use strategic environmental monitoring to guide sediment-related risk management decisions for mixed land use watersheds. The goal of this project was to provide a sound scientific framework based on recent state of the practice in sediment-related risk assessment and management for research and regulatory activities. As a result, shortcomings in the extant data and measurement and modeling tools were identified that can help determine future research direction. The compilation of information is beneficial to the coordination of related work being conducted within and across entities responsible for managing watershed-scale risks to aquatic ecosystems. 相似文献

Considerable progress in addressing point source (end of pipe) pollution problems has been made, but it is now recognized
that further substantial environmental improvements depend on controlling nonpoint source pollution. A watershed approach
is being used more frequently to address these problems because traditional regulatory approaches do not focus on nonpoint
sources. The watershed approach is organized around the guiding principles of partnerships, geographic focus, and management
based on sound science and data. This helps to focus efforts on the highest priority problems within hydrologically-defined
geographic areas. Ecological risk assessment is a process to collect, organize, analyze, and present scientific information
to improve decision making. The U.S. Environmental Protection Agency (EPA) sponsored three watershed assessments and found
that integrating the watershed approach with ecological risk assessment increases the use of environmental monitoring and
assessment data in decision making. This paper describes the basics of the watershed approach, the ecological risk assessment
process, and how these two frameworks can be integrated. The three major principles of watershed ecological risk assessment
found to be most useful for increasing the use of science in decision making are (1) using assessment endpoints and conceptual
models, (2) holding regular interactions between scientists and managers, and (3) developing a focus for multiple stressor
analysis. Examples are provided illustrating how these principles were implemented in these assessments. 相似文献

公众参与在突发性环境污染事件风险管理中可以发挥重要作用。根据参与者在风险管理中的不同作用,将公众划分为个体公众、社会团体、专家学者、新闻媒体4个类型;从风险管理的3个阶段(预防与准备、应急响应、事故恢复)出发,对各阶段具体工作中所需要的公众参与者类型、参与内容及形式进行了探讨。该研究为突发性环境污染事件风险管理中的公众参与提供了一些新的思路和方法,对有效提高风险管理水平具有借鉴意义。 相似文献
