Cleanup Instructions for Small Mercury Spills - revised

Exposure to the small amount of mercury found in common household devices, such as fever thermometers, thermostats, or fluorescent light bulbs, is not likely to cause serious health problems. Humans are frequently exposed to greater quantities of mercury, much of it methylmercury, through diet. Nevertheless, all mercury spills, regardless of quantity, should be treated seriously and cleaned up ...
