论述造纸行业控制可吸附有机卤化物的必要性

造纸业漂白过程会带来可吸附有机卤化合物的污染,这是一类含有包括二恶英在内的多种有毒有机物。随着全球贸易进程,控制造纸业可吸附有机卤化合物的排放已经刻不容缓。控制造纸行业可吸附有机卤化物应从工艺技术、排放标准执行、监测等方面着手。     

煤矿酸性矿井水的形成及主要处理技术

酸性矿井水是煤矿区环境地质灾害的一种重要类型。煤矿酸性矿井水是煤矿开采中由于硫铁矿与空气、水接触,在微生物作用下经过一系列地球化学反应产生的一种危害矿井生产、破坏生态环境的有害矿井排水。文章首先分析了酸性矿井水的形成机理,然后从酸性矿井水的危害入手,分析评价酸性矿井水各种处理方法的优缺点,并对酸性矿井水的处理技术进行总结,最后展望酸性矿井水处理的未来发展方向。

Occupational exposure to natural radioactivity in a zircon sand milling plant

Raw zirconium sand is one of the substances (naturally occurring radioactive material, NORM) which is widely used in the ceramic industry. This sand contains varying concentrations of natural radionuclides: mostly U-238 but also Th-232 and U-235, together with their daughters, and therefore may need to be regulated by Directive 96/29/EURATOM. This paper describes the method used to perform the radiological study on a zircon sand milling plant and presents the results obtained. Internal and external doses were evaluated using radioactivity readings from sand, airborne dust, intermediate materials and end products. The results on total effective dose show the need for this type of industry to be carefully controlled, since values near to 1 mSv were obtained.     

Strategic Framing of Climate Change by Industry Actors: A Meta-analysis

This study uses framing theory to analyze 38 studies on industry actors' climate change communication between 1990 and 2010. It identifies three consecutive phases, each characterized by one dominant master frame: in the early and mid-1990s the US fossil fuel and coal industry pushed the frame of scientific uncertainty. With the rundown to the Kyoto negotiations in 1997, the strategy shifted toward the socioeconomic consequences of mandatory emission reductions, particularly in the USA and Australia. At the same time, European industry actors started to promote industrial leadership in a climate protection, which today dominates across all the world regions. The study discusses potential triggers for the regional differences as well as the implications for further research.     

Exploration of Science Parks

Abstract

Science parks have developed greatly in the world, whereas empirical researches have showed that science parks based on linear model cannot guarantee the creation of innovation. Hi-tech innovation is derived from flow and management of information. The commercial and social interactions between in-parks and off-park firms and research institutions act as the key determinant for innovation. Industrial clustering is the rational choice for further developing Chinese science parks and solving some problems such as the lack of clear major industries and strong innovation sense, etc.     

Farmers' Willingness-to-Pay for Environment and Human Health and Adoption of IPM

Abstract

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 environment 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.     

Strategic Study on Integration of Port and City Development in Rizhao

Abstract

Agglomeration of the Yangtze Delta (UAYD), one of the most developed regions of China, has witnessed an increasing prevalence in building ecological cities when the ecological cities are pursued by many modern cities, and great achievements have been made in this regard. It is inevitable, however, that certain problems exist during the construction of ecological city, which include but not limited to non-harmonious development of urban complex ecosystem, and the difficulty in quantifying eco-city construction or incomplete quantification in assessing the construction of present and future eco-city. Based on the analysis on social-economic conditions and regional conditions of the UAYD, this paper attempts to set up an index system of eco-cities combining with local characteristics, and to adopt the indices of eco-city, urban harmony, and eco-city colligate to evaluate the ecological level, urban harmonious development and eco-city construction of cities within the UAYD. Results indicate that among 15 cities in UAYD, Suzhou City ranks the highest in terms of eco-city construction, whereas Nantong ranks relatively lower; sustainable eco-city construction is possible only when cities are developed in every respect of harmony.     

Economic Globalization and Industrial Pollution

Abstract

In order to study the relationship between economic globalization and industrial pollution, this paper developed the theoretical framework and used simultaneous equations. The result shows that economic globalization has influences on the industrial pollution mainly by the direct effect of scale, structure and technology as well as the indirect effect of income and policy. Considering all the factors, economic globalization, especially foreign direct investment (FDI), will reduce industrial pollution, in which technology spillover effect plays an important role.
