项目摘要

The aim of this study is that performs the quantitative analysis of endocrine disrupting chemicals(environmental hormone) by the development of high-speed・high-powered concentration separation.The produced fruits during the term of three years are as follows :The 1st.year : 2002(1)The optimized condition of each factor was established for new phase separation phenomena with various kinds of polar solvent.(2)The concentration method using homogeneous liquid-liquid/high performance liquid chromatography system was developed.The 2nd.year : 2003(1)Capillary electrophoresis(CE) was found as an analytical method which adapted to homogeneous liquid-liquid extraction.(2)The harmony between high-speed treatment of sample water using solid extraction and homogeneous liquid-liquid extraction was discussed.Based on the investigated fruits until 2nd.year, the triplex concentration system(TRICOM method) was developed. It is constructed by solid extraction with blue cotton/homogeneous liquid-liquid extraction/CE on line concentration.The 3rd.year : 2004(1)In river water as a practical sample, ultra trace of polyaromatic compounds(PAHs) was determined by TRICOM method.(2)The evaluation of TRICOM was done in detail.In conclusion, the satisfactory results were obtained in this project according to the original plan. The proposed TRICOM system was able to determine the ppt levels of PAHs contained in environmental water. The all procedure time was within one hour and the maximum concentration rate was ten million times(from 20 liter to 2 micro liter). In the near future, not only this useful method will be applied to wide range of practical sample, but also the proposed concept will distribute to do break through in the marginal measurement.

这项研究的目的是通过发展高速和高功率浓度分离来对内分泌破坏化学物质（环境骑马）进行定量分析。在三年期间，生产的成果如下：1st.year：2002（2002（1）使用各种相位分离的浓度分离的方法是使用各种相位的浓度（2）。开发了液态液/高性能液相色谱系统。第二年：2003（1）毛细血管电泳（CE）作为一种分析方法，适用于均匀的液 - 液态萃取。（2）使用固体提取和均匀液体液体提取的固体液体液体的高速处理。开发了系统（Tricom方法）。它是通过蓝色棉/均匀液体液体提取/在线浓度上的固体提取来构建的。第三年：2004（1）在河水中作为实用样品，通过tricom方法确定了多芳族化合物（PAHS）的超痕迹。（2）详细完成了Tricom的评估。最终，按照满意度的结果，该计划的结果是在此项目中得到的。拟议的三粒系统能够确定环境水中包含的PAH的PPT水平。所有程序时间都在一小时内，最大浓度率为一千万次（从20升到2微升）。在不久的将来，不仅将这种有用的方法应用于各种实用样本，而且所提出的概念也将分布在边际测量中破裂。
