Improper disposal of mercury can impact state water supplies or be released into the air as gas emissions. Mercury is among a group of pollutants that do not break down or go away.

Mercury is a potent neurotoxin that interferes with the way nerve cells function and can cause damage to the brain, kidneys and lungs. For more information, click on the links below:
