The Thermal Discharges From Nuclear Power Plants in Taiwan

The increasing use of sea water for industrial cooling presents a real threat to the ecological environment in the ocean. in Taiwan where many electric power plants along the coast take sea water for cooling, people are concerned seriously about nuclear power plants. There are three nuclear power plants in Taiwan. Each plant has two units for generating power. the first two are located along the northern coast of Taiwan. the third is located in Kenting National Park along the coast of southernmost Taiwan. the plants take sea water for cooling, and discharge their heated effluents to the ocean surface from the coast. the thermal effluents have variable effects on the ecological environment near the plants. Fishermen living near the power plants complain that the heated water affects the inshore fishery catch. in addition, the thermal water from the second plant is easily accumulated near the coastal zone to influence the nearby swimming area in the summer-time. the thermal water from the third plant bleaches or kills some corals in shallow water near the outlet, and this conflicts with the interests of Kenting National Park.     

圆形烟道烟尘采样点位置确定之正误

采样点位置的确定是烟尘测试中的一项基础工作。在全国沿用10多年的确定圆形圆形烟道烟尘采样点位置的计算表中的数据,经验算有60％有误;原来以烟道中心为基准的计算公式虽然正确,但实用性差。为了进一步完善烟气测试理论,提高监测质量,提出以烟道内壁为基准的新计算公式。运用新、旧2种计算公式得到一致的计算结果—新计算表,进一步证实了原计算表中的错误。     

Multi-level screening of a proposed hazardous waste treatment and disposal facility site--a case study

A comprehensive environmental assessment (EA) is a pre-requisite before the site for developing a hazardous waste treatment and disposal facility (HWTDF) is selected. However, the resource limitations, especially for developing countries, often dictatethat the detailed EA be restricted to those sites, which are constraint free and have low hazard potentials. Thus, a preliminary screening exercise for assessing the suitability ofsite for developing the HWTDF needs to be carried out to avoid huge costs involved in detailed EA. While screening a HWTDF site,various factors such as present land use, ecologically sensitiveareas, geology and hydrogeology of the area, the quality and quantity of wastes, engineered safeguards, and the operationalprocedures that need to be adopted, are required to be addressed. In this paper, a multi-level screening criteria employing RemoteSensing, Constraint Mapping, Groundwater Pollution Potential Index (DRASTIC Index), and the Site Ranking was used to assess the suitability of a proposed site for the development of HWTDF.The study helped to identify various constraints at the proposedsite and their significance on the development of the HWTDF.

长江口滨岸潮滩沉积物中磷的环境地球化学特征

研究了长江口滨岸潮滩表层沉积物中磷的分布、形态等环境地球化学特征。结果表明该地区表层沉积物中磷的含量水平在18．0-31．4μmol/g之间，最大值出现在浦东白龙港污水排放口附近，长江口滨岸潮滩沉积物中磷的分布呈现明显的空间和季节性变化规律，这主要与潮滩不同地段磷的来源、沉积物质地的差异，以及水动力、环境介质条件和生物作用的时空变化密切相关。此外，沉积物中磷的形态分级研究表明大部分沉积磷以无机磷形式存在，其中无机磷又以钙结合磷为主；有机磷比例较少。其次，潮滩沉积物表层上覆水中可溶磷的浓度一般都大于沉积物间隙水，沉积物-水界面中磷主要以累积作用过程为主。

胶州湾潮间带和沿岸区硫酸盐还原菌含量分布

用 Ｍ Ｐ Ｎ 法对胶州湾潮间带和沿岸区的硫酸盐还原菌（ 缩写为 Ｓ Ｒ Ｂ） 含量作了研究，结果表明表层沉积物的 Ｓ Ｒ Ｂ 含量大约是４１ ×１０７ 个细胞／ｇ ，波动范围较大。水中的 Ｓ Ｒ Ｂ 含量约２５ ×１０２／ｍｌ。分析了 Ｓ Ｒ Ｂ 含量的分布状况，发现调查区内的 Ｓ Ｒ Ｂ 含量基本上呈现出北高南低、西高东低之势，即工业区、港口区的高于海水浴场、海滨旅游区的。证实了生活废弃物的排放致其环境 Ｓ Ｒ Ｂ 含量特高。 Ｓ Ｒ Ｂ 含量分布状况大体上与以往所测环境污染状况一致。对虾养殖池的 Ｓ Ｒ Ｂ 含量意味着水产养殖必须考虑这一因子的作用

Method of pollution sources assessment in relation to residential site selection

Much investigation supports a high incidence of disease and death rates when people live in ambient polluted air for a long time. Thus, the location of residential sites is important from a public health viewpoint. The method outlined in this paper is useful for determining the location of residential sites based on pollution sources assessment.
