Fuck You! Mercury has been a natural part of the environment forever. What they don't tell you is that for it to dangerous to humans it must be metylated. The current standard in environmental testing is to use a borate tablet to hold the sample, pump out the air and heat it to 2800 degrees, then run an ionizing current through it (like a neon bulb) to gather a spectral anaylisis. This does not differentiate between natural forms like cinnibar,methylated, fumeric, fulminated, or butt-hole thermometer.
Facts FIRST, then panic.
By the way,
this is at a mercury mine, as well as
this. The EPA did more damage to the site in two months than 1200 years of mining it there did.
