Most people think of mercury as nothing but a toxic nuisance.  Actually, that is far from the truth.  While mercury is toxic in many situations, modern life as we know it would be essentially impossible without that element.  It is also a material known from antiquity, and has drawn the interest of learned folks since then.

Mercury is unique in that it is the only metal to be a liquid at room temperature.  Actually, it is liquid from around minus 39 degrees Celsius to around 360, so it has a almost a 400 hundred degree liquid phase.  That is also sort of odd, since many metals have much longer liquid ranges.

Let us investigate this unique material, and see how it impacts our lives.  You might be surprised.

Sen. Barack Obama can add another accomplishment to his legislative record.

Today, the Chicago Tribune reports Obama-sponsored mercury-storage bill now sent to Bush.

Stockpiles of toxic mercury kept by industry soon will be stored safely in the United States instead of ending up on the world market where it might pollute the environment.

Under bipartisan legislation Congress sent to President George W. Bush Monday for his expected signature, mercury exports would be banned in 2013 and the Energy Department would be required to store the heavy metal permanently.

The bill’s chief sponsor, Sen. Barack Obama, introduced the bill in response to… mercury contamination in fish.

And last year, because of pressure from Obama and “a handful of other senators”, the Department of Energy agreed to “keep its own 1,300-ton stockpile of mercury off the market” as well.
