1、Making the bulbs requires workers to handle mercury in either solid or liquid form because a small amount of the metal is put into each bulb to start the chemical reaction that creates light.───制造这些灯泡需要工人们直接处理固态或液态的水银,因为每个灯泡中要封入小量的该种金属用来发生化学反应以发光。
2、Fluorescent lights use electricity to excite mercury vapor. This produces ultraviolet light that causes a phosphor coating inside the bulb to glow.───荧光灯用电激发水银蒸气。这会生成紫外线光而使得镀在灯管内壁上的磷涂层发光.
3、An incandescent bulb can emit as much as 18 mg of mercury into the air over its lifespan; a CFL emits 9 mg (including the mercury both in the bulb and that emitted by power plants).───单个白炽灯泡在其使用周期内会往空气释放高达18毫克的水银,而一个节能灯只会释放9毫克(包括灯泡和电厂释放量的总和)。
