一、国际上限制使用氟利昂的情况关于氟利昂对环境破坏问题,1974年美国加利福尼亚大学F·S·Lorad教授第一次发表了“氟利昂排放到大气中,几乎不分解地到达同温层,在同温层,由于紫外线的作用,被分解了的氯原子对臭氧进行破坏。其结果,到达地球表面的紫外线量增强。这样,除可能导致皮肤癌的发生率上升外,对人类的生活状态也会发生重大的影响”的论文。此后,1976年,美国环境保护团体发表了氟利昂分阶段地禁止作为空气溶胶喷射剂使用的主张,1978年开始实施了该主张。在联合国,国际环境计划会议上也提出了这个问题,1977年臭氧问题调整委员会开始工 I. International restrictions on the use of freon On the issue of freon damage to the environment, Prof. S. Lorad of the University of California, USA, for the first time in 1974 published the article “Freon emissions to the atmosphere, reaching the stratosphere almost invariably, Stratosphere, due to the role of ultraviolet light, the decomposition of chlorine atoms on the destruction of ozone .As a result, the amount of ultraviolet rays reaching the Earth’s surface increases. In addition to this may lead to an increase in the incidence of skin cancer, the state of human life will be A significant impact on the ”thesis. Since then, in 1976, the U.S. Environmental Protection Group published a proposition on the phased banning of Freon as an aerosol propellant, which was implemented in 1978. At the United Nations, the International Environment Planning Conference also raised this issue. In 1977, the Ozone Committee for Adjustment began to work
