The trash man is probably at a pretty low risk, but ultimately all the mercury in the CFL lamps that aren't properly recycled will end up in the earth, and hence the ground water, or to some extent in the air due to incineration of trash containing CFLs. In the long run we will probably regret ever introducing large numbers of them into the economy.
In the meantime, I intend to make sure the word about Tom Reed's vote gets out.
