欧美经验对我国“十三五”大气污染防治战略的启示

当前,我国大气污染形势严峻,复合型污染特征突出。新修订的《中华人民共和国环境保护法》、《中华人民共和国大气污染防治法》、《环境空气质量标准》以及《大气污染防治行动计划》的发布和实施,对我国大气污染防治工作提出了更高要求。"十三五"时期是我国环境保护负重前行困难期和大有作为关键期,也是我国改善大气环境质量的攻坚期,需要系统谋划大气污染防治战略。欧盟和美国在制定大气污染防治战略时,以改善空气质量为核心,构建了涵盖一次污染物和二次污染物的多污染物目标体系,规定了环境浓度、排放量、直观感受(能见度)、健康以及管理等约束性指标,并且针对大气污染防治政策分析实施的成本与收益,开发相应的模型工具,基于收益成本比进行科学决策。本文对欧美环境规划和战略中的多污染物协同控制目标体系以及大气污染防治政策成本效益评估经验进行梳理,分析我国大气污染防治战略的现状和问题,并提出相关政策建议,以期为解决"心肺之患"、实现环保"十三五"总体目标提供参考。     

A human ecological assessment of air quality management: A convergence in economic and ecological thinking?

Traditional air pollution management practices are examined using the human ecological framework adopted by Boyden and others (1981) in their study of Hong Kong—the biohistorical or biosocial approach. The subsequent analysis of current air quality management practices assesses their effectiveness in protecting the overall health of both humans and the natural environment. The uncertainties inherent in air pollution management practices which emerge highlight the need to reduce emissions rather than rely on scientific knowledge to define clean air. The assessment also clearly defines roles for research in various areas such as atmospheric models, health effects, and environmental damage. The final recommendations emphasize the need for the introduction of such incentives to reduce emissions as economic instruments and warn against using health information to define clean air. Health and environmental damage information can, however, be used in risk assessment strategies together with atmospheric dispersion models.     

Can China control the side effects of motor vehicle growth?

Motor vehicle growth in China is the fastest in the world. This is placing great strain on the urban environment and causing a rapid increase in oil imports and motor vehicle carbon dioxide emissions. To deal with the environmental and health effects of air pollution, China has adopted a strong motor vehicle pollution control programme and imposed limits on fuel consumption of new light duty vehicles. The article will review these problems and programmes. Special focus will be given to the need to reduce sulphur levels in both gasoline and diesel fuel.     

Industry's role in air quality improvement: Environmental management opportunities for the 21st century

More than 200 years ago, Adam Smith, the founder of modern economics, wrote in the Wealth of Nations that “…consumption is the sole end and purpose of all production; and the interest of the producer ought to be attention to…that of the consumer.” In recent years, the rapid growth of the world economy has given Adam Smith's maxim new meaning. The age-old desire for consumption grows unabated and increasing numbers of consumers around the world are attaching new value to the environmental quality of goods and services and expressing concern over the environmental impacts of industrialization. That concern is growing because more than 70 percent of the world's urban population live in areas where the air is seriously polluted and as many as 750,000 people—the majority in developing countries—die each year of ailments caused by air pollution.¹ Over the past 25 years, corporations throughout the world have made dramatic changes in the way they do business as more people come to understand how the ecological system works and how polluted air and water endanger human health. The key to increasing industry's participation in the drive for higher standards of air quality is the growing realization that effective environmental management, technological development, and technology dissemination are cost-effective and profitable business strategies. Global competition is making firms around the world more customer-conscious and, to the extent that consumers demand products that minimize environmental degradation and enhance the quality of their lives, businesses in every industry must respond in order to survive.² This article examines how changes in business practices, driven by a better understanding of how natural environments function, are converging to provide new opportunities for environmental management that go beyond regulatory compliance to reduce air pollution. Although sound and well-enforced environmental regulations are an essential foundation for improving air quality, command-and-control systems alone are unlikely to achieve the lower levels of pollution that will be necessary to achieve sustainable development in the 21st century. In cooperation with government, businesses in every industry can play crucial roles in achieving higher standards of air quality while at the same time maintaining acceptable levels of economic growth. We explore three ways in which corporations can contribute to environmentally sustainable development: (1) by adopting proactive environmental management systems that focus on air pollution prevention; (2) by developing new technologies for air pollution control and reduction; and (3) by transferring air pollution control and prevention technologies through international trade and investment.     

城市环境安全模糊综合评价方法研究

北京作为我国的首都、环境保护的首善之区,在环境问题上应该,也必须是安全的。但实际上,北京大气污染、水体污染日益加剧,水资源紧张,环境安全形势严峻。本文根据2005—2014年十年环境污染统计数据,运用层次分析法、灰色聚类分析法对北京市城市环境安全进行了评价分析,结果表明,北京市城市环境安全度为6.3~6.89,属于较安全级别。十年来北京市环境安全状况呈好转趋势,环境安全度最低值出现在2006年,最高值出现在2011年,增幅9%。地表水的氨氮、BOD、高锰酸盐指数及大气污染中的PM10污染相对严重。PM10安全度指数2005—2007年偏低,由于奥运减排措施的持续作用及沙尘影响减弱,2006—2013年安全度逐年增高,2014年安全度略有下降,但整体呈好转趋势。北京市地表水污染仍为有机污染型,2005—2014年的十年间,通过结构减排、工程减排、监管减排等措施,地表水有机污染得到很大改善,各项污染物浓度总体呈下降趋势。总体而言,环境空气质量仍未达标,水环境污染仍较突出,应针对评价结果加大相应的环境治理措施,确保首都环境安全。

The Environmental Pollution Perception of Residents in Coal Mining Areas: A Case Study in the Hancheng Mine Area, Shaanxi Province, China

The environmental behavior of the residents depends on their perception of environmental pollution. Hence, it is important for scientific and policy experts to research on the impact of the environmental pollution perception of local residents. Owing to the richness of natural resources, Hancheng coal mine areas are abound in heavy industries, and environmental pollution is serious and typical in this area, thus, the residents are anxious about their health. Using questionnaires, this paper surveys the perception of residents living in the coal mine area. The influential factors of environmental perception were analyzed by the Rank Sum Test. The results were: (1) the majority of the residents in the coal mine area are not satisfied with their living environment. The perception order of pollution severity is: air pollution?>?noise pollution?>?sanitation?>?water pollution. The residents think that pollution is mainly caused by coal processing. Hence, coal mining is not the main reason of the pollution in the coal mine area. (2) Age and length of residence have significant positive effects on perceptions of air, water, and noise pollutions; whereas education has a significant negative effect on perceptions of water and noise pollutions, as well as sanitation. This phenomenon can be explained by the various cultural groups having varied perceptions on the environmental pollution. In addition, proximity to mine has significant negative effect on perceptions of water and noise pollution. In conclusion, the paper discusses the effects of demographical and social factors on the perception of environmental pollution and gives suggestions on the planning and management of the environment.     

Environmental Planning, Biodiversity and the Development Process: The Case of Hong Kong''s Chinese White Dolphins

Hong Kong has enjoyed more than 20 years of almost uninterrupted economic growth and the territory is widely recognized as one of the most successful of the newly industrializing economies. Economic success has, however, brought with it a variety of environmental problems including deterioration of air and water bodies and the loss of terrestrial and marine habitats. Environmental degradation also poses a serious threat to local biodiversity. Despite its stated commitment to environmental protection, the Hong Kong Government is still strongly growth-oriented and the territory's environmental institutions and policies often seem ineffective in resolving the conflicts that arise between development and the environment. To illustrate some of the contradictions inherent in Hong Kong's current approach to environmental and conservation issues, this paper focuses on the controversy surrounding the fate of the local population of the Indo-Pacific humped-back dolphin, or, as it is locally known, the Chinese white dolphin (Sousa chinensis). The dolphin's habitat has been disrupted by major development projects, marine pollution and fishing and shipping activity. It is possible that the species will be extinct in Hong Kong waters by the beginning of the next century. The paper examines the background to the controversy that has arisen surrounding the future of the dolphins and evaluates the Government's attempts to develop a conservation strategy to protect them. The preferred option—the creation of a dolphin sanctuary within a designated marine park area—has been strongly criticized by some local marine biologists and conservationists as being inadequate and inappropriate. The failure to address effectively the problems faced by the Chinese white dolphin may be attributed to the lack of an overall conservation strategy in Hong Kong, shortcomings in the territory's environmental impact assessment system and limited local scientific knowledge concerning the dolphin population.     

A review of the Nigerian petroleum industry and the associated environmental problems

Nigeria has abundant deposits of oil and natural gas and their exploitation has improved the economy substantially, but with serious environmental costs. Severe ecological damage has occurred in the Niger Delta area where most of the oil industries are based. Statutory rules and regulations for environmental protection applicable to the oil industry in Nigeria appear to be generally inadequate and ineffective. So far, air pollution has not been properly addressed. Natural gas is still being flared from many oil wells, with serious air pollution problems and a waste of this resource. The legal control of air pollution in the light of the ongoing operations of liquified natural gas (LNG) and compressed natural gas (CNG) projects is advised along with other measures for environmental quality, control and the conservation of resources.

Particulates pollution management and economic analysis of small rural enterprises in mountain areas: A case study of Wenquan town in China

At present, many rural enterprises in China's mountainous areas are developing rapidly, and due to poor planning and improper management, in an uncontrolled manner. These small enterprises are making atmospheric pollution far more serious and more difficult to control than before. Thus, as is the case with most developing countries, China is facing the challenge of managing the increased environmental pollution that is accompanying its economic development. This paper examines the case of cement dust pollution in the town of Wenquan in Sichuan province in order to determine how to adjust the relationship between development of rural enterprises and atmospheric environmental pollution in mountainous areas. Using the single objective linear programming method, and based on the principle of overall optimization, an optimal control plan for different pollution sources was worked out and an economic assessment on reclamation of cement dust was completed. According to our analysis, after implementation of this plan for four years, two months, the concentrations of suspended particles in Wenquan will achieve the requirement of the national third-order ambient air quality standard; the current serious dust pollution will be completely controlled; and the reclamation of cement dust will totally compensate for the cost of dust control and will result in 92,000 yuan of pure profit per year. At that time, the economy and environment will be in harmony.     

Attitudes About Recreation, Environmental Problems, and Estuarine Health Along the New Jersey Shore, USA

/ Management of ecosystems has advanced by an improvement in our understanding not only of how ecosystems function, but of how people perceive their functioning and what they consider to be environmental problems within those systems. Central to such management is understanding how people view estuaries. In this article I explore the perceptions and attitudes of people about coastal recreation, environmental problems, and future land use along the New Jersey shore (USA) by interviewing people who attended a duck decoy and craft show on Barnegat Bay. The people who were interviewed engaged in more days of fishing than any other recreational activity and engaged in camping the least. There were significant differences in recreational rates as a function of gender and location of residence, with men hunting and fishing more than women and photographing less than women. Jet skis were perceived as the most severe environmental problem, with chemical pollution, junk, oil runoff and overfishing as second level problems. Birds were perceived as not an environmental problem at all. Fishing, hiking, preservation, and camping ranked as the highest preferred future land uses for the two sites examined (Oyster Creek Nuclear Generating Station, Naval Weapons Station Earle). The preferred future land uses for these two sites, which are not under consideration for land-use changes, were very similar to those of people living near the Department of Energy's Savannah River Site in South Carolina, despite the media attention and considerations of nuclear storage.KEY WORDS: Recreation; Perceptions; Environmental problem; Gender; Land use; Coastal     

Studies on soil parameters of sediments from the River Ganga phosphorus mobilization,interactions with sediment and the phosphorus cycle

Large quantities of sediment are transported by the River Ganga (The Ganges) particularly In its deltaic region. Attempts have been made to study the physicochemical parameters of the bottom sediments of the River Ganga at various depths at Kamarhati and along the banks of the River Ganga in the lower deltaic region. The results give vital information regarding the pollution load carried by the river and the enrichment of its sediments with nutrients such as P, N and other substances such as C and S (as sulphates). The mobilization of the P, N, C and S (as sulphates) in the sediments is compared with their natural abundance. The enrichment of the river beds with P, the interaction of the sediment and the characteristics of the sediments are ascertained. Some aspects of the phosphorus cycle and its importance are also discussed. The recycling and reuse of sediments for agricultural purposes have been proposed in order to restore ecological imbalances due to nutrient loss.Mrs M. Chattopadhyay (née Ray) and D.

Emergent aspects of environment: A creative challenge

Summary Our environmental situation continues to decline faster than ever. This is demonstrated by, the growing spread of pollution of both the water and atmospheric systems, erosion of topsoil, tropical deforestation, desertification, mass extinction of species, depletion of the ozone layer, and climatic dislocations. Compounding the impact of these problems is growth in human numbers in developing countries, together with the associated factor of extensive poverty. The author asks why our environmental situation should continue to decline, despite a remarkable outburst of awareness on the part of the general public and its political leaders since the time of the Stockholm Conference on the Human Environment. The author concludes that the problem does not lie with inadequate effort, rather with misdirected effort: we persist in tackling the symptoms of problems, rather than the problems themselves, let alone the sources of the problems. The paper broaches these issues within a context of fast-growing interdependence among the community of nations — both economic and ecological interdependence — which presents yet more problems, but also raises many opportunities for creative action.Professor Norman Myers is a consultant in environment and development.

浙江省环境污染与经济发展关系的实证研究

本文在环境库兹涅茨曲线假设基础上,采用1991—2014年浙江省环境和经济数据,运用回归模型对其环境污染与经济发展的关系进行实证检验。结果表明:浙江工业废水、工业废气、工业SO2排放量和工业固体废弃物产生量均符合EKC假设,其中工业SO2和工业废水人均排放量与人均GDP呈倒U形关系,拐点分别出现在2005年与2010年;工业废气排放量和工业固体废弃物产生量尚处于倒U形左侧上升阶段,其中工业固体废弃物人均产生量已接近拐点。而生活污水排放量与EKC假设并不相符,人均生活污水排放量与人均GDP呈单调递增的线形关系。对EKC驱动因子的分析表明,加强政府环境治理,以不断完善的环境法规推动产业结构升级调整,以持续的技术进步与创新促进关键行业节能减排,有利于克服规模效应,推动浙江环境污染与经济发展的关系早日实现解耦。     

中国三大城市群经济能源交通结构对比及其对大气污染的影响分析

本文从经济、能源、交通结构三大领域分析了京津冀、长三角和珠三角三大城市群的异同点,探究了结构性特征对大气污染的影响。结果表明:我国东部三大城市群中,珠三角的空气质量最优,长三角次之,京津冀最差,空气污染程度自南向北呈现阶梯状上升态势;能源规模和结构、工业规模和结构、交通规模和结构同步呈现自南向北逐步偏化石燃料、偏重工业、偏公路运输的结构性特征,与空气污染的阶梯分布在一定程度上相吻合。从时间来看,空气污染呈现历史性发展和累积特征;从空间来看,重工业规模大、比重高,化石燃料在能源消费结构中占比高,汽车保有量和船舶货物吞吐量快速增高是京津冀和长三角大气污染重于珠三角的内在结构性主因。在数据分析的基础上,本文从分区施策和结构调整两方面提出了大气污染防控对策建议。

Fly ash for the treatment of Zn(II) rich effluents

Summary The ability of fly ash to remove Zn(II) from water by adsorption has been tested at different concentrations, temperatures and pH of the solution. It was found that low adsorbate concentration, small particle size of adsorbent and higher temperature favoured the removal of Zn(II) from aqueous solution. The Langmuir isotherm was used to represent the equilibrium data at different temperatures. The apparent heat of adsorption has been found to be 17.325 Kcal mol^–1, which indicates the process to be endothermic. The uptake of Zn(II) is diffusion controlled and the mass transfer coefficient is 3.56 × 10^–5 cm s ^–1.The maximum removal was noted at pH 7.5. Dr V.N. Singh is Professor and Head of the Department of Applied Chemistry, Dr A.K. and Prof. D.P.

Integrating fire management into land-use planning: A multiple-use management research,development, and applications program

The traditional view of fire as a destructive agent requiring immediate suppression is giving way to the view that fire can and should be used to meet land management goals. Thus,fire control is being replaced by the more general concept offire management, which is based on the need to integrate fire policy with land management objectives. The social, economic, and ecologic effects of fire must be evaluated in the selection of land management alternatives.The activities of fire management organizations—fire prevention, control, and use of fire—must respond to needs of land management. Many agencies have developed fire organizations as separate entities that set their own objectives. The many land and resource managers who have recognized the need to incorporate fire considerations into land-use planning have so far lacked the techniques to do so.As a natural process, fire has an important function in forest and range ecosystems. Fire can greatly influence the quantity and quality of resource outputs; it is a two-edged sword that can either harm or benefit our goals, depending upon the complex effects of fire and the nature of our wants.The Fire in Multiple-Use Management Research, Development, and Applications (RD&A) Program was initiated by the U.S. Department of Agriculture, Forest Service, at the Northern Forest Fire Lab in Missoula to assist land managers. This profile explains what an RD&A program is; discusses its mission, goals, and approach to the problem; and tells why the approach involves federal laboratories, universities, and private research foundations.     

Managing Asia's environmental crisis: EQM opportunities for remediation and technology transfer

Conditions of environmental pollution and degradation in Asia are among the worst in the world. Rapid economic growth and industrialization over the past half century have accelerated the pollution of air, water, and land resources in a region with the world's largest concentration of population. As the economics of Asia recover from financial crisis in the late 1990s, they will face a more serious environmental crisis in the early years of the 21st century. Remediation of soil and water contamination will become a stronger concern in the region, as the human health impacts become more visible and widespread. Although environmental remediation is only beginning to emerge in Asia as a solution to problems of natural resource degradation, the authors show how U.S. firms with experience in quality environmental management and biological remediation technologies will find new opportunities for exports and technology transfer. Environmental technology and services firms interested in Asia must understand both the opportunities for and barriers to operating in Asia.
