Nobody almost died from the lead poisoning! Did you even watch that episode? Morgan Edge poisoned the pools at some school in order to frame Lena. Also Lena established that the amount of lead in the atmosphere is only enough to affect Daxamites which seem to be killed by a low amount of lead. Mon-El is the only Daxamite left, and he dealt with that problem by removing his weakness in the future. All Lena would get out of removing all the lead would be the minor satisfaction of clearing the atmosphere of every substance that isn't air.
