As the mercury rises so does the level of mercury in the soil

Increased greenhouse gases will not only increase the earth's temperature. They will apparently bring us more mercury in the soil and thus the plants and animals we eat. An experiment done by the Oak Ridge National Lab found increased CO2 in the atmosphere also increase the level of mercury in the soil.

As we are seeing in the Tennessee coal ash snafu, coal burning results in waste with mercury content. Both the gases and the ash. Here's some info from EPA on how to get mercury out of coal plant gaseous emissions. In the soil, mercury can be leach into the water table. It doesn't alter the taste of our drinking water.
