Florescent lights that used to made here in the states, never used Mercury, that was an addition when they started being made in China. Now they are all made in China, and they are all dangerous. Even most of the reports I have heard, are less to do with breathing, which is what your report deals with Edward, and had something to do with contact. The contact part I never understood until I saw this article. Something to do with the mixture on Mercury that makes this a very dangerous contact toxim. I agree with you on Tuna, and tilapia, which are both rising on the Mercury lists, and now Tuna is rising on the Radio contamination charts as well.
