There are only a few domains in EU where mercury UV lamps are still allowed (like water treatment) and to my knowledge the phase out is already decided
- kragen 2y agothat's ridiculous, we're talking about metallic mercury in milligram quantities. you can swallow metallic mercury in kilogram quantities without apparent ill effects because its bioavailability is so low thanks for explaining the dismayingly superstitious situation!
- magicalhippo 2y agoIsn't the issue inhaling mercury vapor[1], not eating it for lunch? And lamps will have it in vapor form if they break while running, no? [1]: https://en.wikipedia.org/wiki/Mercury_poisoning#Elemental_mercury https://en.wikipedia.org/wiki/Mercury_poisoning#Elemental_me...
- kragen 2y agoyes, inhaling large amounts of mercury vapor is pretty bad, although still not in the same league as something like methylmercury or cadmium sulfide nanocrystals. i'm not really sure what happens if the lamp breaks while it's running, but i don't think it's a significant risk remember, what we're talking about here are perfectly normal fluorescent tubes, just without the phosphor and the ultraviolet-blocking glass. same thing that was in every office and classroom throughout the latter half of the 20th century. if the tube breaks the broken glass is a much bigger risk than the mercury
