国际臭氧层保护日 国际臭氧层保护日(International Day for the Preservation of the Ozone Layer)
每年的9月16日是国际臭氧层保护日。
随着人类活动的加剧,地球表面的臭氧层出现了严重的空洞,1974年被美国加利福尼亚大学的教授罗兰(F.Sherwood Rowland)和穆连(Mario Molina)发现。
1987年9月16日,全球46个国家的代表在加拿大蒙特利尔签署《关于消耗臭氧层物质的蒙特利尔议定书》(目前已有170多个国家签署),标志着各国将对保护臭氧层即将开始具体行动。
1995年,联合国规定,从当年起每年9月16日为国际臭氧层保护日,旨在纪念“蒙特利尔议定书”的签署,并唤起公众的环保意识。 1995年1月23日,联合国大会通过决议,确定从1995年开始,每年的9月16日为“国际保护臭氧层日”。旨在纪念1987年9月16日签署的《关于消耗臭氧层物质的蒙特利尔议定书》,要求所有缔约国根据“议定书”及其修正案的目标,采取具体行动纪念这一特殊的日子。

September 16 was designated by the United Nations General Assembly as the International Day for the Preservation of the Ozone Layer.
This designation was made on December 19 1994, in commemoration of the date, in 1987, on which nations signed the Montreal Protocol on Substances that Deplete the Ozone Layer.
In May 1985 in the journal Nature British Antarctic Survey scientists reported their discovery of an ‘ozone hole’ over Antarctica. The United Nations Environmental Programme proclaims 16 September the International Day for the Preservation of the Ozone Layer, commemorating the date in 1987 on which the Montreal Protocol on Substances that Deplete the Ozone Layer was signed. All but three of the UN Member States have now ratified the Protocol. The Montreal Protocol gives the world an example of how to successfully control a global environmental problem.
