This research focuses on the heavy metal contamination of the paddy soils and rice from Kočani Field (eastern Macedonia) resulting
from irrigation by riverine water impacted by past and present base-metal mining activities and acid mine drainage. Very high
concentrations of As, Cd, Cu, Pb and Zn were found in the paddy soils (47.6, 6.4, 99, 983 and 1,245 μg g−1) and the rice (0.53, 0.31, 5.8, 0.5 and 67 μg g−1) in the western part of Kočani Field, close to the Zletovska River, which drains the mining facilities of the Pb–Zn mine
in Zletovo. In terms of health risk, the observed highest concentrations of these elements in the rice could have an effect
on human health and should be the subject of further investigations. 相似文献

This paper offers a new perspective on the environmental laws in Asian nations affecting the exploration, mining, and reclamation activities of the mineral resource industry: the perspective of the senior government officials in those countries, whose job is to enforce these new environmental laws. The article presents the results of a 1998 survey of national environmental officials in Asia conducted by the Colorado School of Mines and the Metal Mining Agency of Japan. Officials in 10 diverse countries—Cambodia, China, Indonesia, Lao PDR, Malaysia, Myanmar, Mongolia, Philippines, Thailand and Vietnam—responded to a detailed questionnaire covering applicable laws, agencies, protected areas, covered mineral activities, financial assurance, environmental impact assessment, public involvement, environmental standards, permit and reclamation requirements.
The survey confirms that Asian nations are part of the global trend towards national government regulatory structures that balance mineral development objectives with environmental considerations. The survey also shows developing regulatory systems (some embryonic, some more mature) utilizing a combination of mining and environmental acts, and often an 'insider' perspective of the national officials administering the laws. While that perspective is not without its biases (not least the rigor of enforcement), it may nevertheless be of use in company planning. The emerging regulatory picture contradicts the conventional notion that it is the 'lower' level of regulation in Asia that is attracting foreign direct investment in mining. 相似文献

The mining industry and the community: joining forces for sustainable social development 总被引:1,自引:0,他引:1
This article joins the continuing policy debate over the social responsibility of corporations, particularly in the mining industry. The author argues that the 'old school mining orthodoxy'—approaching the exploitation of mineral deposits solely from the technical and economic points of view—is long dead. Mining companies must also encompass the social dimension.
New policies for the mining industry are discussed in terms of recent worldwide trends and movements, e.g. globalization, economic interdependence and decentralization of governmental authority, and the rise of civil society as a political factor. These trends, together with the United Nations policies in quest of sustainable development and the consensus expressed at international conferences during the last decade, have deepened social awareness and set the stage for enhanced social responsiveness from the private sector. Socially responsible corporate policies include decentralization of decision-making to the field level, reaching out to stakeholders and shareholders, supporting governments which provide official development assistance for good governance and building broad partnerships to reduce social exposures. 相似文献

Identification of mining-related contaminants is important in order to assess the spreading of contaminants from mining as well as for site remediation purposes. This study focuses on lead (Pb) contamination in biota near the abandoned ‘Black Angel Mine’ in West Greenland in the period 1988-2008. Stable Pb isotope ratios and total Pb concentrations were determined in lichens, seaweed and mussels as well as in marine sediments. The results show that natural background Pb (207Pb/206Pb: 0.704-0.767) and Pb originating from the mine ore (207Pb/206Pb: 0.955) have distinct isotopic fingerprints. Total Pb in lichens, seaweed, and mussels was measured at values up to 633, 19 and 1536 mg kg−1 dry weight, respectively, and is shown to be a mixture of natural Pb and ore-Pb. This enables quantification of mining-related Pb and shows that application of Pb isotope data is a valuable tool for monitoring mining pollution. 相似文献

Mining generates risk of environmental and social harm for Indigenous peoples but can also generate substantial revenues for them, creating opportunities for community development in a context where economic and social disadvantage is the norm. Especially as mining revenues should, in part, compensate for mining’s negative social and environmental impacts, it is vital that mineral taxation on Indigenous lands reflect a careful assessment of appropriate tax mechanisms and a matching of these with community priorities. Yet little has been written that could serve as a guide for Indigenous decision makers. This article contributes to an understanding of the issues and choices facing Indigenous communities in designing mineral taxation regimes, by focusing on the question of economic risk. Risk arises as a key variable in choosing or designing a mineral taxation regime in three ways. Different approaches to mineral taxation are inherently more or less risky, in the sense that they are more or less certain to generate tax revenues. A second aspect of risk involves the degree of economic certainty or predictability associated with different types of commodities and projects. Third, the risk tolerance of Indigenous peoples and communities can vary significantly. We show how Indigenous groups can integrate and address these different dimensions of risk, by recognising the ‘risk consequences’ associated with different approaches to mineral taxation and choosing an approach that reflects, as fully as possible, the group’s risk tolerance. 相似文献

The environmental pollution associated with mining and metallurgical activities reaches its greatest extent in several Andean cities and villages. Many locations in this area have accumulated through centuries a large amount of mining wastes, often disregarding the magnitude of this situation. However, in these naturally mineralized regions, there is little information available stating the exact role of mining and metallurgical industries in urban pollution. In this study, we demonstrated that the various metallic elements present in indoor dust (As, Cd, Cu, Pb, Sb, Sn, Zn) had a common origin and this contamination was increased by the proximity to the mines. Lead dust concentration was found at concerning levels for public health. In addition, wrong behaviors such as carrying mining workwear home contributed to this indoor dust pollution. Consequently, the constant exposure of the population could represent a potential health hazard for vulnerable groups, especially children. 相似文献

GIS与环境模拟在环境地学研究中的作用和意义 总被引:6,自引:0,他引:6
21世纪全球环境问题将更加突出,环境地学应为研究、解决环境问题做出更多的贡献。但是,环境地学研究所采用的方法和手段还不能满足客观的需要。文章着重讨论了环境模拟系统(EnvironmentalImitationSystem,EIS)的建立及EIS与地理信息系统(GeographicalInformationSystem,GIS)的耦合等问题。作者通过研究,认为上述问题已基本得到解决.从而可以弥补GIS中环境模拟功能的不足,可使EIS纳入GIS的信息空间管理系统,进行信息空间管理、应用分析和信息叠加,并使信息可视化。文章最后指出.目前,可建立GIS-EIS联合系统,以实现信息互换和信息资源的二次开发、利用。 相似文献
