大气溴甲烷的释放与控制研究

大气溴甲烷是破坏大气臭氧层的主要化合物之一,既有人为释放,也有自然释放,目前还存在着巨大的未知源。了解大气溴甲烷释放规律和控制措施,不仅对保护臭氧层具有重要意义,而且是大气溴甲烷含量的历史追溯和未来预测的重要基础,是全球变化研究热点。全面介绍了大气溴甲烷排放的途径和机制以及调控排放通量的主要措施,并分析了近期的优先研究领域。

A review of studies on the emission and control of atmospheric methyl bromide

Atmospheric methyl bromide (CH3Br) is considered one of the most most important ozone depletion compounds. It is believed that there are unknown sources of atmospheric CH3Br emissions even though some kinds of anthropogenic sources and natural sources have been identified. The realization of the properties of CH3Br emissions and the control methods, which is the basis both for the exploration of the history of and the prediction of the future of the content of atmospheric CH3Br,is very important on the protection of ozone layer. This issue is broadly focused recently. An comprehensive introduction of the sources,mechanisms,and control methods of atmospheric CHsBr releases are presented in the paper. Some preference study fields are also proposed.
