Transboundary air pollution balance in the new integrated European environment

Ten out of the 12 new EU members, used to belong to the so-called “former eastern block”, with a post WWII environmental policy radically different from the tendencies followed in Western Europe. The lack of conservation regulations has resulted in a rather harmful industrialization, regarding natural resources and environmental quality. While air pollution transfer is a phenomenon of transboundary level, there is a particular interest in examining the contribution of the new EU member states to the environmental pressure faced by the older member states and vice versa. The current study utilises the official data for almost 20 years published by the European Monitoring and Evaluation Program concerning the transboundary transfer of NO_x and SO₂ in order to analyse the situation and discuss the present and future environmental policy regarding air pollution.     

Influence of new town development on the urban heat island - The case of the Bundang area

Five new towns have been developed around the Seoul metropolitan area since 1996. However, these new towns generate lots of traffic and related problems in the areas including those new towns and Seoul as a result of increases in population and a lack of ecological-self-sufficiency. Currently, construction of another new town is under deliberation, and what should be a major consider is the notion that the new town be located within a wide, green zone. Many studies have revealed that green space can play an important role in improving urban eco-meteorological capability and air quality. In order to analyze the urban heat island which will be created by the new urban development, and to investigate the local thermal environment and its negative effects caused by a change of land use type and urbanization, Landsat TM images were used for extraction of urban surface temperature according to changes of land use over the last 15 years. These data are analyzed together with digital land use and topographic information. As a study result, it was found the urban heat island of the study area from 198.5 to 1999 rapidly developed which showed a difference of mean temperature above 2.0. Before the Bundang new town construction the temperature of the residential area was the same as a forest, but during the new town construction in 1991 analysis revealed the creation of an urban heat island. The temperature of a forest whose size is over 50% of the investigation area was lowest, and thus the presence of a forest is believed to have a direct cooling effect on the urban environment and its surroundings. The mean temperature of the residential and commercial areas in the study was found to be 4.5 higher than the forest, and therefore this part of land use is believed to be the main factor causing the temperature increase of the urban heat island.     

新型工业化进程中的消费与高新技术污染

随着新型工业化的发展,污染治理已实现了从单纯的末端治理向在生产过程中治理转变的跨越式发展。但新的环境问题如消费废弃物污染的面更广,内容更多和高新技术污染等相继出现。这些污染应引起人们的广泛关注。     

上海市机动车排污状况与污染控制战略

通过对上海市中心城区机动车行驶工史现状的主要特点及发展趋势的分析，计算出中心城区１９９５年机动车尾气排放的ＣＯ、ＮＭＨＣ和ＮＯｘ负荷，分别占区域内机动车和固定源产排放总量的７６％、９３％和４４％，据预测，到２０１０年，中心城区内机动车排出的ＣＯ、ＮＭＨＣ和ＮＯｘ负荷，将分别占区域中机动车和固定源排放总量的９４％、９８％和７５％，因此，针对机动车排污所面临的严峻挑战，需要采取加强机动车检查与维修（Ｉ
