If your old house has lead paint in good condition, cover it with fresh paint rather than removing it, which releases lead dust into the air. 如果你的房子曾经刷过含铅的油漆，并且漆层还比较好，最好的方法是用新的不含铅的油漆覆盖旧的漆层，而不是去除老的含铅的漆层，因为这样做，铅尘反而排放到空气当中了。 - 2
The lead poses little threat if undisturbed but "replacing old windows or drilling into walls to blow in insulation, for example, can contaminate the house with lead dust," CELA said. 在没有施加外力影响的情况下，铅的危害并不大。 但是CELA解释说：“比如，在更新旧的窗户或者钻进墙壁中嵌入绝缘材料的时候，可能使房间受到铅尘的污染。” - 3
