沧州炼油厂恶臭污染与防治浅析

炼油厂在生产过程中产生的废气易引起环境恶臭污染，通过对污染源进行治理，加强生产管理，杜绝无组织排放，实行有效监督是防止恶臭污染的关键。     

济南市二氧化硫污染现状及防治对策

近年来，济南市的经济快速发展，但随之而来的环境污染特别是大气污染则日益加剧。空气中总悬浮颗粒物、二氧化硫和氮氧化物等主要污染物都不同程度的超过国家规定的环境质量标准，特别是冬季二氧化硫污染相当严重。据监测，１９９７年冬季采暖期间，空气中二氧化硫的平均浓度为０－３６５ｍｇ／Ｎｍ３，为非采暖期的３－６倍，若在逆温、静风等不良气候条件下，二氧化硫日均值可达１－０ｍｇ／Ｎｍ３，超过国家二级空气质量标准的５－７倍。由于受二氧化硫污染影响，冬季空气质量时有恶化。１９９７年１１月下旬连续数日出现酸雾。二氧化硫…

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.

燃煤引起的氟污染

氟是煤中的有害元素，煤燃烧时，煤中氟被释放出来，本文叙述了煤在燃烧过程中，氟化物形态的转化、释放氟的规律，氟在大气环境中的迁移，扩散机理，为氟污染的评价和防治提供科学依据。     

云南空气中TSP的现状与控制

云南省１９９０￣１９９６年１７个城镇的ＴＳＰ污染水平一直在０．２０ｍｇ／ｍ＾３左右波动，比较平稳。将年平均浓度值与超标率相比较，历年来ＴＳＰ的污染程度变化不大，但污染面有逐年扩大的趋势。因此，为提高空气质量达标率，必须加强管理和技术方面的措施。
