A pot experiment was conducted to investigate the influence of citric and oxalic acids effect on Pb and Zn uptake by corn and winter wheat. The experiment was employed with citric acid (CA) applied at 3 rates (0, 1.5 and 3.0 mmol kg-1 soil), oxalic acid (OA) at 3 rates (0, 1.5 and 3.0mmol kg-1 soil) and citric acid combined with oxalic acid (1.5 mmol citric acid combined with 1.5 mmol oxalic acid kg-1). Two types of soil were chose in the experiment. One was collected from the agricultural soil near a battery-recycling factory in Anhui province, China (site A) and the other was collected from a Pb-Zn mine residues in Hunan province, China (site B). The results showed that soil pH varied with the different treatment of citric and oxalic acids. However, there were no differences in all the treatments. 3.0mmol CA kg-1 soil addition significantly increased the concentrations of the CaCI2-extractable Pb and Zn and other treatments have no significantly increased. The highest shoot concentrations of Pb and Zn  相似文献

Although chemical control of pests increases crop production, it brings a lot of damage to environment and human health. There exist a number of alternative methods that are not so harmful to environment and human health. However, whether and how much in extent these technologies adopted are plausible depends on the comparison of benefit-cost between chemical control and the alternative control methods (such as Integrated Pest Management, IPM) and farmers' willingness-to-pay (WTP) for envirorment and human health. Using contingent valuation method (CVM), the author investigates farmers' WTP for environment and human health, recognizes the factors influencing WTP, and accordingly points out the importance of pest control technology extension and government regulation of pesticides.  相似文献

ABSTRACT

Formula 1 motor sport and the Men's World Cup of association football, two major sporting events on our calendars, are indirectly and directly responsible for environmental despoliation. They serve as advertisements for heavy industry, are designed for elite as much as mass consumption, and provide sponsors with dubious social licenses to operate. This occurs through the very mechanisms of the events themselves (engines in Formula 1, tourism in the World Cup) as well as their promotional externalities. I look at greenwashing claims made about these two sporting events and examine counter-discourses, then investigate economic and ecological citizenship. I suggest that a progressive agenda can be forwarded if Greenpeace, which runs campaigns related to these sports, works with its fellow elites, in the case of Formula 1, and with fans in the case of football. Doing so may be more effective than business-as-usual direct action.  相似文献

Abstract

This article discusses holistic well-being in a balanced work system theory framework. Holistic well-being is a combination of well-being in both work and non-work domains. Theories of balanced work systems and balanced organisations are retold in light of holistic well-being to show how different individuals in organisations can contribute to achieving desired outcomes at different process levels. Further, this article provides new insights and research challenges to the balanced organisation theory by including a sustainability aspect and by proposing a new concept of balanced value networks.  相似文献

Comparing agricultural management practices across scales and in different cultural settings can reveal shared insights into the capacity to adjust and respond to change and uncertainty. Differences make comparisons in environmental risk perceptions and responses particularly interesting and valuable, with obtained similarities being in many ways more interesting than found differences, which might be readily expected in places with remarkable geographical and demographic differences. People’s perception of climatic risks and hazards appears to be important to understand the context in which adaptation strategies to climate change emerge. Our intention, rather than compare the two case studies at the local scale, one in Mexico and one in Spain, is to identify existing common mechanisms to perceive climate change and to address adaptation among two very different geographical and cultural contexts. The study aims first to explore people’s perceptions of climate change and its outcomes; second to analyse the adaptation measures that they have developed and develop some preliminary ideas about their strategies; and third to consider the capacity of people to cope and adapt endogenously, in terms of the measures that people think that their governments should take to enhance/strengthen them at the local scale.  相似文献

Engineered nanomaterials (ENM) are expected to hold considerable potential for products that offer improved or novel functionalities. For example, nanotechnologies could open the way for the use of textile products outside their traditional fields of applications, for example, in the construction, medical, automobile, environmental and safety technology sectors. Consequently, nanotextiles could become ubiquitous in industrial and consumer products in future. Another ubiquitous field of application for ENM is fa?ade coatings. The environment and human health could be affected by unintended release of ENM from these products. The product life cycle and the product design determine the various environmental and health exposure situations. For example, ENM unintentionally released from geotextiles will probably end up in soils, whereas ENM unintentionally released from T-shirts may come into direct contact with humans and end up in wastewater. In this paper we have assessed the state of the art of ENM effects on the environment and human health on the basis of selected environmental and nanotoxicological studies and on our own environmental exposure modeling studies. Here, we focused on ENM that are already applied or may be applied in future to textile products and fa?ade coatings. These ENM's are mainly nanosilver (nano-Ag), nano titanium dioxide (nano-TiO(2)), nano silica (nano-SiO(2)), nano zinc oxide (nano-ZnO), nano alumina (nano-Al(2)O(3)), layered silica (e.g. montmorillonite, Al(2)[(OH)(2)/Si(4)O(10)]nH(2)O), carbon black, and carbon nanotubes (CNT). Knowing full well that innovators have to take decisions today, we have presented some criteria that should be useful in systematically analyzing and interpreting the state of the art on the effects of ENM. For the environment we established the following criteria: (1) the indication for hazardous effects, (2) dissolution in water increases/decreases toxic effects, (3) tendency for agglomeration or sedimentation, (4) fate during waste water treatment, and (5) stability during incineration. For human health the following criteria were defined: (1) acute toxicity, (2) chronic toxicity, (3) impairment of DNA, (4) crossing and damaging of tissue barriers, (5) brain damage and translocation and effects of ENM in the (6) skin, (7) gastrointestinal or (8) respiratory tract. Interestingly, some ENM might affect the environment less severely than they might affect human health, whereas the case for others is vice versa. This is especially true for CNT. The assessment of the environmental risks is highly dependent on the respective product life cycles and on the amounts of ENM produced globally.  相似文献

From an economic point of view, the industrial economy is efficient to overcome situations of a scarcity of goods. From a technological point of view, the resource efficiency of the manufacturing processes of the industrial economy has been permanently improved during the last 200 years. In addition, cleaner processes have been developed. However, from an ecologic point of view, an increasing world population with increasing consumption has produced a "global footprint" which approaches the carrying capacity of the planet. A circular economy and its high-value spin-offs-a lake economy and a performance or functional service economy-can fulfil customers' needs with considerably less resource consumption, less environmental impairment in production and considerably less end-of-life product waste, especially in situations of affluence, when a considerable stock of physical goods and infrastructures exists. Also, in situations of a scarcity of natural resources, both energy and materials, often characterised by rapidly rising resource prices, the economic actors of a circular economy have a high competitive advantage over the actors of the industrial economy, due to much lower procurement costs for materials and energy. From a social point of view, a circular economy increases the number of skilled jobs in regional enterprises. However, the shift from a linear manufacturing economy to a circular or service economy means a change in economic thinking from flow (throughput) management to stock (asset) management: in a manufacturing economy with largely unsaturated markets, total wealth increases through accumulation as resource throughput (flow) is transformed into a higher stock of goods of better quality (but in a manufacturing economy with largely saturated markets, wealth represented by the stock of goods will no longer increase); in a circular or service economy, total wealth increases through a smart management of existing physical assets (stock) that are adapted to changes in both technology and customer demand. This second approach not only applies to physical capital but equally to social capital, such as health and education and green GDP. To measure the social wealth of a population, it is not the amount of money spent on schools and hospitals that matters, butif this expenditure has led to a better education of the students, and a better health of the people.  相似文献

Science, politics and environmental policy have for several years been encountering social and institutional as well as scientific challenges, national and international. The normative basis of all sciences is pressurised from three sides: by awareness of the public, who claims more transparency and sensibility from the scientific institutions regarding factual or possible impacts of science-based industrial progress; by the industries, which try to speed up and intensify the industrialisation of knowledge; and by the public policies, which want to see the sciences engaged in ways to mitigate unintended consequences of economic, ecological and social developments. At the same time, environmental policy is undergoing a tremendous sea change both in conceptual and practical matters. Since the Brundtland Report in 1987 and accelerated after UNCED 1992, environmental policy has been struggling to become a groundbreaking new paradigm for the capacity of resolving social and political issues as well. Any successful attempt to alter traditional institutional and mental structures in policy-making toward sustainability presupposes a renewed association of co-operation, deliberation and decision making. Results from theory of democracy, studies in science and technology, and evaluation studies in environmental policy and politics can be utilised for this context.  相似文献

Abstract

Along with the rapid growth of economy in the postreform period after 1979, China has faced severe problems of resource overusing and environmental degradation which would threaten the sustainable development of economy and society. This article explores an effective mechanism of managing resource and environment in China. It examines some major resource and environmental issues, and constructs a framework of institution innovation to cover three sectors (government, market and society). In addition, the article analyzes their experience and evaluation in resource management and environmental conservation during the transitional period. We argue that the combination of market regulation, government intervention and public participation is an effective way of allocating resource and protecting environment. Some suggestions are put forward to balance the relationship between them, including coordinating role of government and market, building platform for market operation and creating an atmosphere of public participation.  相似文献

本文构建了多主体参与环境治理的动态一般均衡模型,进行了政府环境规制下的企业内生治理动机研究与公众参与外部性的分析,模拟结果显示,企业内生治理动机、社会福利等不同目标下对应的最优环境税率存在明显差异。随着政府环境税率的不断上升,企业环境技术研发投入会先上升后下降,当环境研发投入水平达到最大时,政府所征收的环境税完全激发了企业的内生治理动机。在环境税率提高的初期,研发引致的环境技术进步使得企业的全要素生产率得以提高,经济产出不断增加,社会福利水平得到增进。当环境税率上升到一定数值之后,环境税带来的资源配置扭曲效应高于环境负外部性的改善效应,对于经济而言,环境税成为扭曲性税收,并会降低社会福利水平。因此,应在保证经济增长和社会福利增进的同时有效激励企业内在治理动机,将环境税率设定在适当水平。本文还模拟了政府与公众参与的组合对于社会福利的影响情况,与仅考虑政府环境规制政策的情形相对比,政府征收环境税和社会组织参与的共同作用可以使得社会福利提高,充分表明了公众参与环境治理存在着正外部性。环境社会组织在一定程度上可以降低政府信息不对称等因素,改善环境治理状况。环境组织的参与还能够使得环境税所带来的环境治理改善和生产效率提高的双重红利逐渐释放。因此,在发挥政府规制与市场调节功能的同时,充分发挥环境社会组织和公众在环境治理中的作用,是改善环境质量、提高公众福利的重要方式。  相似文献

公用事业民营化及其环境行为政府管制的研究   总被引:1,自引:0,他引:1  
公用事业民营化的目的是在公用事业行业引入民间资本和市场竞争模式,提高公共产品服务的产出质量和效率。以电力行业的民营化为例,电力市场对于民营企业的开放能够在很大程度上提高我国电力生产水平.解决当前电力供求关系紧张的问题。但是,大量民营企业介入电力生产,由于其技术落后而导致的资源浪费以及污染物的无序排放给我国的环境保护带来了新的困扰。我们应该在科学发展观和构建社会主义和谐社会的目标指引下,加强政府对于电力企业等公用事业民营化企业生产经营活动的法律管制,同时加强和完善相关的环境立法,达到公用事业积极发展和环境保护目标实现的双赢目标。  相似文献

环境管制政策的局限性与变革--自愿性环境政策的兴起   总被引:8,自引:0,他引:8  
我国虽然基本上避免了环境质量急剧恶化的局面。但是现行环境政策并没有从根本上遏制环境状况不断恶化的趋势,我国环境政策的效率亟待摄高。究其原因,我国环境政策以行政直控的管制政策为主。具有强烈的行政管理色彩,使得政府和企业的博弈长期锁定在非合作状态。要摆脱这种困境,必须引入第三方激励、监督机制。促使双方的博弈转变为合作博弈。20世纪90年代中期自愿性环境政策的渐渐兴起,是企业和公众在产品市场上互相影响的结果。而政府起到引导激励、信号传递作用。文章从博弈论的角度对此进行了分析,自愿性环境政策缓解了环境管制成本与效果冲突的困境,是未来环境政策的一个重要的方向。  相似文献

This article focuses on the problems of water governance at a river basin level, and on the role of institutional coordination, participation and partnerships between multiple stakeholders towards sustainable water management. Its approach presupposes that institutional capacity building, strengthening coordination between government institutions (vertical and horizontal), on the one hand, and broadening participation and consolidating partnerships between public, private and civil society actors, on the other hand, is among effective tools in integrated water resource management in river basins. It explores environmental challenges, problems, emerging trends and recent institutional innovations in the Volga basin in Russia—the largest river basin in Europe. Transfer and adaptation of good practices in good water governance between the EU and Russia are discussed. This article presents some research findings and lessons learned from practice by the EC international project ‘CABRI—Cooperation along a big river: Institutional coordination among stakeholders for environmental risk management in the Volga basin’, which is assessed as one of the selected success stories of the European research.’  相似文献
