Other causes are eating fish that have been exposed to mercury in the environment. Industrial and workplace exposure such as in a paint industry or hospital poses a potential threat of mercury poisoning. Even breakage of thermometer at home can cause serious mercury poisoning. The mercury vapors that linger in air can be particularly hazardous.
Exposure to mercury may even occur through cosmetics. There have been several cases of mercury poisoning in the South-West states by a company that sold a beauty cream with calomel  listed as an ingredient. Calomel  is mercurous chloride (HgCl2). This product had mercury levels around 10%. In Germany, there were cases of mercury poisoning through the use of over the counter hair bleaching products that had no warning label concerning the contents. The results were loss of hair and discolored fingernails.
Considering the severity of mercury poisoning, it is a must that you prevent any hazards of mercury exposure. Warn your family about the potential dangers of mercury in household items. Most importantly, guard your kids against accidental mercury exposure. Keep them away from the reach of mercury containing items like thermometers, medical devices, some disinfectants, fluorescent light bulbs, etc. Read the labels before buying any product and look for any mercury warning sign.
