Unit 5 Chemistry of the AtmosphereIntroduction to Chemistry of the Atmosphere➢The thin gaseous envelope that surrounds our planet is integral to the maintenance of life on earth.➢环绕我们星球的薄气层是地球上维持生命所不可或缺的。
➢The composition of the atmosphere is predominately determined by biological processes acting in concert with physical and chemical change.➢大气的组成主要是由与物理和化学变化协同作用的生物过程决定的。
➢Though the concentrations of the major atmospheric constituents oxygen and nitrogen remain the same,the concentration of trace species, which are key to many atmospheric processes are changing.➢虽然大气中主要成分氧和氮的浓度保持不变,但对许多大气过程起关键作用的微量物种的浓度正在发生变化。
➢It is becoming apparent that man's activities are beginning to change the composition of the atmosphere over range of scales, leading to, for example, increased acid deposition, local and regional ozone episodes, stratospheric ozone loss and potentially climate changem. In this part.➢越来越明显的是,人类的活动开始在一定范围内改变大气的组成,例如,导致酸沉降增加、局部和区域臭氧事件、平流层臭氧损失和潜在的气候变化。
