矿物资源量和储量分类的发展及中国固体矿产资源/储量分类的修订

矿物资源量和储量的分类已经有上百年的发展历史了,美国人曾经做出了重要的贡献。最早的分类是20世纪初的关于矿石的分类,之后提出了矿物资源的总分类及其框架,为国际通用矿物资源量和储量分类标准的形成奠定了基础。1989年澳大利亚的JORC标准首次颁布,1996年加拿大CIM标准颁布,1998年加拿大NI 43-101标准颁布,形成了国际通用的矿物资源量和储量的分类标准。中国矿产储量分类最早是采用前苏联的,历经半个世纪的演变,到1999年颁布了现行的矿产资源/储量分类。现行的矿产资源/储量分类与国际通用标准不相通,特别是不适应于市场经济环境,修订现行的矿产资源/储量分类势在必行。

建筑材料生命周期评价中不可再生资源耗竭性当量的研究

不可再生资源耗竭研究是生命周期评价体系的重要组成部分。在对不同材料进行生命周期评价时,传统的锑当量或铁当量会影响不可再生资源耗竭性结果的客观性。本文以传统建材产品为研究对象,利用CML方法,提出了不可再生资源耗竭性当量—硅当量,并比较了采用不同当量对建筑材料生命周期评价结果的影响。结果表明,采用硅当量得到的建筑材料环境负荷比采用铁当量得到的结果更符合实际。     

An environmental assessment of wood and steel reinforced concrete housing construction

Wooden type of housing is ubiquitous in Japan. It is the main structure for housing; however, due to the increase in residential developments, steel reinforced concrete houses are also on the rise. This paper assesses the environmental impacts of these two types of construction. An evaluation of the two types of construction in terms of energy usage and air emissions is done. A comparison of the damage costs due to the generated emissions is also considered. Four types of emissions generated are evaluated, namely carbon emissions (CO₂), nitrogen oxides (NO_x), sulfur oxides (SO_x) and suspended particulate matter (SPM). The life cycle of the two different housing construction types is traced and environmental impacts are determined. External costs are also calculated. Furthermore, different improvement assessment scenarios are simulated to ascertain several emission reduction possibilities. The study looks into the emitted emissions from the housing construction to its final disposal of a typical residential development in Saga, Japan. Results show that much of the environmental impacts from building a house are on the Global Warming Potential due to high carbon emissions. Moreover, the construction phase generated the highest pollutant emissions from nitrogen oxides, sulfur oxides and suspended particulate matter. Steel reinforced concrete (SRC) construction has a higher environmental impact compared to the wooden type of housing construction. A longer design life for a residential house gives a reduction of about 14% in carbon emissions. Using solar energy for the operation phase has gained a reduction of 73% in the total life cycle carbon emissions.

Learning from the social construction of environmental indicators: From the retrospective to the pro-active use of SCOT in technology development

This article explores the challenges, advantages and limitations of the pro-active use of the social construction of technology (SCOT) to improve the methods applied in the development of technology for use by a broad range of actors. Our example is the development of environmental indicators for buildings (EIFOBs). We compare the pro-active use of SCOT with both the ‘traditional’ use of SCOT and with the ‘traditional’ way of developing EIFOBs. pro-actively applying SCOT in developing EIFOBs has the potential of bridging some of the communication gaps at the boundaries between the various professional groups in a multi-actor decision-making process. Using SCOT in a pro-active way means the research becomes action research and the researcher goes beyond the role of a mere observer and becomes an actor too. This means the researcher has to consider the criteria for valid action research when designing and carrying out the research.

A sustainable framework for water resources management in an urban watershed: the case of Volos,Greece

The implementation of sustainable development principles in water resources management refers to an integrated management and coordination of the entirety of the actions and interventions that concern the water ecosystem, or parts of it, within a watershed. This procedure is accomplished through the development and application of an overall management plan at a hydrological basin level. This concept was followed by the water resources management plan of the city of Volos' watershed, which is presented in this paper. The main objective is the choice of the best set, among others, of hydraulic projects, which will be able to re-establish the balance in the basin's deficient water budget, satisfying at the same time future urban water demand. Decision making was carried out using a GIS tool and involved traditional water capture hydraulic projects on the one hand and sustainable water saving measures on the other. The whole procedure is being developed in an area with serious environmental problems, concerning mainly the groundwater resources. The particularity here is that the alternative solutions strongly depend on administrative agreement and consensus between relevant authorities.     

Comparative study of pre-treatment procedures for H monitoring in water samples from environmental protection programs

The determination of tritium activity in water samples is included in most environmental protection programs, and the recommended procedure consists of sample distillation and further measurement by liquid scintillation. Distillation is a simple but time consuming pre-treatment, especially in routine analysis. Here we evaluate alternative pre-treatments for tritium activity determination, such as filtration or the use of multiple selective ion exchange columns. 52 samples from different water sources (rain, surface, underground, sea and drinking water) in Spanish environmental protection programs, together with an IAEA reference material were analyzed. Results show that both pre-treatments can be applied as a preliminary tool to discriminate between tritium active and non active waters in environmental monitoring programs. In addition, filtration and multiple selective ion exchange column pre-treatments can be used as alternative procedures for tritium activity determination in the routine analyses of water samples with known and reproducible chemical and isotopic composition. Both methods are less time consuming than distillation and, in the case of filtration, extremely cheap.For waters with complex matrices, especially sea water, distillation is the recommended procedure due to the interference from salts contained in the sample.
