环境污染是人类生产与生活活动产生的污染物在环境中积累造成的,而工业污染源——各种类型的工厂——生产过程中排放的污染物是造成环境污染的重要原因。因此,要防治环境污染必须重视污染源调查这项基础工作,只有通过污染源调查,准确、系统地掌握污染源的污染排放情况和排放规律,才能正确地选择污染源治理方案,制订可行的环境污染防治对策。 相似文献

本文通过梳理我国污染源监管的历史沿革和日益严峻的环境污染问题,理清我国现阶段在污染源整个生命周期的不同阶段由不同环境部门主导的污染源监管模式和在此模式下形成的数出多源的数据库基本情况。从时间、空间、参与者三个角度分析该模式的缺点,针对环境统计、排污申报、排污收费等多个污染源数据库进行分析比较,列表找出各自数据的特点。通过分析指出我国污染源管理存在的不足,主要体现在污染源信息管理碎片化、多元化,数据互通性差,难以实现交换和共享,导致环境部门数据可靠性不高,信息公开不全面,社会公信力缺失。究其根本原因是我国目前缺乏一整套统一的、紧密衔接的污染源协同监管模式以及顺畅的污染源全过程管理数据流程。文章从实行排污许可证一证式管理制度、污染源企业报告制度、信息公开制度、加强违法处罚力度和完善企业环境信用等方面提出政策建议。 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

This paper provides an analysis of pollution prevention, treatment and cure with respect to solvent-based processes. It is postulated that, in new processes, considering environmental constraints in the early stages of process design can prevent pollution due to inefficient recovery of solvents or inefficient separation by solvents. Pollution in existing processes can also be prevented through early treatment that includes assessment of causes and effects of future changes in process conditions and/or environmental regulations. Pollution cure is more difficult, since the process is already violating some environmental constraints and any solution also needs to satisfy social and economic constraints. A technique for pollution prevention, treatment and cure that is based on the use of computer-aided tools is presented. Application of the technique is illustrated through a case study that highlights the important steps of the solution approach and serves as a proof of concept. 相似文献

Establishing aquatic restoration priorities using a watershed approach 总被引:11,自引:0,他引:11
Since the passage of the Clean Water Act in 1972, the United States has made great strides to reduce the threats to its rivers, lakes, and wetlands from pollution. However, despite our obvious successes, nearly half of the nation's surface water resources remain incapable of supporting basic aquatic values or maintaining water quality adequate for recreational swimming. The Clean Water Act established a significant federal presence in water quality regulation by controlling point and non-point sources of pollution. Point-sources of pollution were the major emphasis of the Act, but Section 208 specifically addressed non-point sources of pollution and designated silviculture and livestock grazing as sources of non-point pollution. Non-point source pollutants include runoff from agriculture, municipalities, timber harvesting, mining, and livestock grazing. Non-point source pollution now accounts for more than half of the United States water quality impairments. To successfully improve water quality, restoration practitioners must start with an understanding of what ecosystem processes are operating in the watershed and how they have been affected by outside variables. A watershed-based analysis template developed in the Pacific Northwest can be a valuable aid in developing that level of understanding. The watershed analysis technique identifies four ecosystem scales useful to identify stream restoration priorities: region, basin, watershed, and site. The watershed analysis technique is based on a set of technically rigorous and defensible procedures designed to provide information on what processes are active at the watershed scale, how those processes are distributed in time and space. They help describe what the current upland and riparian conditions of the watershed are and how these conditions in turn influence aquatic habitat and other beneficial uses. The analysis is organized as a set of six steps that direct an interdisciplinary team of specialists to examine the biotic and abiotic processes influencing aquatic habitat and species abundance. This process helps develop an understanding of the watershed within the context of the larger ecosystem. The understanding gained can then be used to identify and prioritize aquatic restoration activities at the appropriate temporal and spatial scale. The watershed approach prevents relying solely on site-level information, a common problem with historic restoration efforts. When the watershed analysis process was used in the Whitefish Mountains of northwest Montana, natural resource professionals were able to determine the dominant habitat forming processes important for native fishes and use that information to prioritize, plan, and implement the appropriate restoration activities at the watershed scale. Despite considerable investments of time and resources needed to complete an analysis at the watershed scale, the results can prevent the misdiagnosis of aquatic problems and help ensure that the objectives of aquatic restoration will be met. 相似文献
