实验室和分析用途四氯化碳的管理现状

Management Status of CTC in Laboratory and Analytical Uses

消耗臭氧层物质(ODS)的淘汰是《关于消耗臭氧层物质的蒙特利尔议定书》中的一项重要任务,但由于四氯化碳(CTC)等一小部分ODS在实验室和分析用途中具有不可替代的作用,缔约方大会为此制定了相应的豁免条款。主要阐述了中国、欧盟、美国和日本关于实验室和分析用途CTC的管理现状,以及国内外涉及CTC标准的修订情况。

The phase-out of ozone depleting substances(ODS)is an important task in the Montreal Protocol on Substances that Deplete the Ozone Layer.However,a small fraction of ODS such as carbon tetrachloride(CTC)is irreplaceable in laboratory and analytical uses.The Conference of the Parties has formulated corresponding exemptions.This article mainly discussed the management status of CTC in laboratory and analytical uses in China,the European Union,the United States,and Japan,and the revision of CTC standards at home and abroad.
