Mercury is an element of the Periodic Table, dum-dum. The periodic element doesn't kill people.
Sometimes, I think. I think of the most important things in life. Like PG. [img src="http://i45.[tinypic].com/3133c60.png"][img src="http://i25.[tinypic].com/10ygymt.png"]
As mercury is a very volatile element, dangerous levels are readily attained in air. Mercury vapour should not exceed 0.1 mg m-3 in air. Air saturated with the vapour at 20°C contains mercury in a concentration far greater than that limit. The danger increases at higher temperatures. It is therefore important that mercury be handled with care. Containers of mercury should be securely covered and spillage should be avoided. Mercury should only be handled under in a well-ventilated area. If you are in possession of any mercury you are advised to contact a properly qualified chemist or public health laboratory for its safe disposal.
