The danger from acute exposure to minimal amounts of mercury is nil. Yet people like you like to create panic and close down schools and send out Hazmat crews for two lousy drops of mercury.
I'll bet you can't find a similar case in the last 40 years.
There was a case of mass mercury poisoning in Iraq in the early 1970's when people ate grain containing a mercury-based fungicide. I don't think there has been anything similar in the last 30 years.
You could pour it into your mouth and you would probably not suffer any permanent ill effects.
In the autobiography of Casanova he recounts what happened after he was given mercury as a cure for a venereal disease. It has such a profound effect on his mind that he joined a monastery in Switzerland. When the effects began to wear off he realized that he had made a big mistake.
The danger from acute exposure to minimal amounts of mercury is nil.
The problem with elemental mercury is that it vaporizes and can be breathed in over a long period of time if it is not cleaned up. So the hazmat crews are not needed because someone might touch mercury. But most people would not want to have their kids going to a classroom where spilled mercury had not been cleaned up. Undoubtedly there is a lot of over-reaction in this area.
There is no doubt that acute exposure to organic compounds of mercury can be highly toxic.
When I was a kid I spilled mercury in my room and some of it remained in cracks in the floor. It's probably still there. Unfortunately I cannot use myself as an example of someone who can point to no possible ill effects.
