MERCURY AND YOUR HEALTH
EFFECTS OF ELEMENTAL MERCURY EXPOSURE:
Elemental (metallic) mercury primarily causes health effects when it is breathed as a vapor where it can be absorbed through the lungs. These exposures can occur when elemental mercury is spilled or products that contain elemental mercury such as flourescent bulbs break and expose mercury to the air, particularly in warm or poorly-ventilated indoor spaces. Health effects from exposure to mercury will vary due to many factors.
Symptoms include these: tremors; emotional changes (e.g., mood swings, irritability, nervousness, excessive shyness); insomnia; neuromuscular changes (such as weakness, muscle atrophy, twitching); headaches; disturbances in sensations; changes in nerve responses; performance deficits on tests of cognitive function. At higher exposures there may be kidney effects, respiratory failure and death. People concerned about their exposure to elemental mercury should consult their physician.
