国外水环境标准与监测方法的发展（上）

介绍了国际卫生组织、美国国家环境保护局及日本最新公布的饮用水中污染物的规定标准、重点介绍了日本新增加的１５控制污染物的物理化学性质、产量和用途、在环境中的行为和毒性等。以有机污染物的监测分析方法为重点，评述了水中挥发性、半挥发性和难挥发性有机污染物试样处理的气提一捕集、顶空法、溶剂萃取法和固相萃取法，以及新的监测分析方法体系。并对日本１９９３年实施和１９９４年将要实施的水质监测新方法进行了概述。

Development of Water Environmental Standards and Monitoring Methods Abroad

Introduction of new standards of pollutants in drinking water published by WHO, USEPB and JIS were presented. The emphasis was laid on the physico-chemical properties, output, usage, environmental behaviour and toxicity of the newly added 15 pollutants, and monitoring and analysis of organic pollutants. The monitoring methods of volatile, semi-volatile and hardly volatile organic pollutants were described- The sample preparation procedures of purge-trap (PT), head-space (HS), solvent extraction (SE), solid phase extraction (SPE) and preconcentration, and some new analytical system were also introduced. Lastly, the Japanese new monitoring methods of water quality, which have been put into effect in 1993 or are going to carry out in 1994 were briefly reviewed.
