A Marine Pollution Study of Northeast Coastal Water Off Taiwan Island

The coastal water of northeast Taiwan island, called 'Yin-Yang Hai' for its distinct yellow colour compared with blue offshore water, was investigated from 1989 to 1990 by the authors. Biological study showed the dominant species of plankton to be Copepoda, Cladocera, planktonic eggs and Diatoma. Dominant species of benthos were young crabs, Amphipoda and Annelida, with Amphipoda usually occurring in heavily polluted areas. Heavy metal data showed that the concentration of copper was high. the copper and iron concentration in algae of the intertidal zone was also high. the concentrations of iron and copper in inshore water were also higher than in offshore water. By comparison of the pH and salinity distribution of this area, we conclude that this coastal water has been polluted by acid waste water from coastal industry. the suspended solids concentration in sea water is high. Flocculation occurring at the boundary of fresh and saline water might be a reason for the distinct yellow colour of the water of this area. Further study is required.

热带海洋环境中BHC和DDT的行为特征研究Ⅰ.中国珠江口区旱季BHC和DDT的含量与分布

本文于1994年11月用气相色谱法研究了旱季珠江口区环境中BHC和DDT的含量与分布。结果表明，表层海水BHC含量为0.187μg/L，DDT为0.080μｇ/L；底层海水BHC为0.117μｇ／L，DDT为0.506μｇ／L。沉积物BHC为11.15×10－9（干），DDT为33.46×10－9（干）。海水中的盐度、DO、C     

海洋现代沉积速率~（210）Pb－~（210）Bi法的射线测定研究

本文主要介绍了用~（２１０）Ｐｂ─~（２１０）Ｂｉ法测定海洋现代沉积速率和数据处理方法的研究。该方法测定的结果与~（２１０）Ｐｂ─~（２１０）Ｐｏ法和阴离子交换－ＥＤＴＡ纯化－硫酸钡镭沉淀－α计数法（简称~（２２６）Ｒａ法）以及厦门大学海洋系经研究改进的分离、纯化~（２１０）Ｐｂ的离子交换法的测定结果相当吻合。     

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
