Human activities are placing enormous pressures on the biosphere. The introduction of new chemicals and the increasing ambient levels of existing chemicals have resulted in atmospheric degradation. This paper reviews some of the adverse effects of stratospheric ozone depletion and global warming. Because the atmospheric effects of ozone depletion are fairly well characterized, quantitative risk estimates have been developed. However, because the atmospheric effects of global warming are less understood, public health problems that could be intensified by climate change are assessed qualitatively. The interactive effects of these two phenomena are also discussed.
人类活动正在给生物圈带来巨大压力。新化学物质的引入以及现有化学物质在环境中的浓度不断增加,导致了大气退化。本文综述了平流层臭氧消耗和全球变暖的一些不利影响。由于臭氧消耗对大气的影响已得到较好的描述,因此已经制定了定量风险评估。然而,由于对全球变暖对大气的影响了解较少,所以对可能因气候变化而加剧的公共卫生问题进行了定性评估。本文还讨论了这两种现象的相互作用。
