Mercury tends to vaporize when exposed to air. The warmer the air, the more quickly it vaporizes. Although swallowing mercury can be a problem, the greater risk results from inhalation and skin absorption. Symptoms and health-related problems can result within hours of exposure. Spilled mercury settles in cracks and absorbent material such as carpet, wood, drapes, and cloth. Over time, the vapors are emitted and inhaled by occupants. Remember, the problem with mercury is that it keeps on recycling itself. It vaporizes, is absorbed by materials in the environment, and again vaporizes. It is a problem that persists until there is intervention! This article discusses short, and long term symptoms of mercury exposure, where mercury is found beyond the school science laboratory, it's properties, safe alternatives, and intervention procedures should a spill occur.
