Today, U.S. corporations are discovering the merit of combining the principles of total quality environmental management (TQEM) into their measurement and communications programs. This approach has been particularly productive in the permitting process that is necessary for starting, expanding, or sustaining plant operations—a procedure that can easily be thwarted in the absence of a prominent and aggressive communications component. The need to benchmark and measure such a communication program'S progress is critical both for internal management and for environmental regulators concerned that an applicant demonstrate a high degree of public involvement. 相似文献

Experiments were performed in a 1.5 MW pilot-scale furnace to investigate the differences between air- and oxy-fired flame behavior from a pulverized coal oxy-research burner designed for flexible operating conditions. The flame behavior was characterized by recording video images of the flames and by measuring radiation intensity along the flame length. Various strategies relating air- and oxy-fired operation of the burner primary register were investigated where the oxy-fired burner primary mass, momentum and velocity were matched to the air-fired conditions. Matching either burner primary mass or momentum under oxy-fired conditions with air-fired conditions resulted in a flame stabilized within the quarl. Matching primary velocity with air-fired conditions resulted in a detached flame indicating a delay in flame ignition for the oxyfired conditions. A decrease in primary velocity of 13% was necessary in order to stabilize a flame within the quarl similar to the air-fired case. Additional experiments also showed a flame could be stabilized with no oxygen enrichment of the primary (~3 vol.%, dry O2 in the primary). Experiments where oxygen was injected at the burner face indicated injection at the boundary of the primary and secondary flow paths strongly attach a flame and injection at the coal rich primary flow path increased the radiative intensity of the flame. 相似文献

This article argues that much of the economic criticism of the Integrated Programme for Commodities has been based on outdated and simplistic models and that fears of ‘dirigisme’ and price raising derive from a misunderstanding of the fundamental focus of the IPC on price stabilization. Moreover, the proposed IPC would, it is argued, generate benefits significantly in exces of its costs, which themselves have often been exaggerated. The article concludes by arguing that compensatory finance should be viewed as complementary to, not competitive with, the IPC. 相似文献

Industrial ecology is a new multidisciplinary field of study requiring that economic activity be integrated with, and have minimal impact on, surrounding natural systems. This systems-based approach is beginning to be implemented in private firms through the development of Design for Environment (DFE) methodologies and tools which support the integration of technological and environmental considerations in all economic activities. As part of this development process, a matrix system is proposed by the author by which the environmental and energy costs embedded in materials as used in generic applications may be identified, facilitating environmentally and economically efficient selection of materials. This Material Environmental Evaluation Matrix is supported by checklists which inform the evaluation process. A set of completed matrices for major materials in common applications forms the basis for an Environmentally Efficient Materials Database (EEMD). Once completed, the EEMD would inform consumers, product and process designers, business planners and managers, regulators and government purchasers, public interest groups, and others in their choice of optimal, environmentally and economically efficient, material options. 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

Securing flows for environmental purposes from an already fully utilized river is an impossible task--unless users are either coerced into freeing up water, or offered incentives to do so. One sensible strategy for motivating users to liberate volumes is to offer them economic compensation. The right amount for that compensation then becomes a key environmental management issue. This paper analyses a proposal to restore and maintain ecosystems on a stretch of the Río Conchos in northern Mexico, downstream from a large irrigation district that consumes nearly all local flows. We present here estimates of environmental flow requirements for these ecosystems and compute compensation figures for irrigators. These figures are derived from crop-specific irrigation water productivities we statistically estimate from a large set of historical production and irrigation data obtained from the district. This work has general implications for river ecosystem management in water-stressed basins, particularly in terms of the design of fair and effective water sharing mechanisms. 相似文献

A method for evaluating areas for national park status 总被引:1,自引:0,他引:1
Sümer Gülez 《Environmental management》1992,16(6):811-818
A procedure for evaluating different areas as national parks based on a scoring system is proposed. A National Park Evaluation
Form (NPEF) evaluating natural, cultural, and recreational resources in accordance with international criteria for national
parks is presented. The evaluation points given to an area indicate the possibility of the area becoming a national park.
In this method, subjectivity and bias have been minimized by a special application of the Delphi technique. The method outlined
here could help in the efforts of selecting and establishing national parks in many countries. 相似文献
