The necklaces were bought in Mexico. They are often a beaded chain, cord, or leather strand with a glass pendant that contains mercury. The mercury appears as a silvery clump of liquid that rolls around in the hollow glass pendant. Pendants can be in various shapes, such as hearts, bottles, saber teeth and chili peppers. If your necklace breaks, leave the room, close the door, and get an adult right away.
Mercury vapors are very harmful.
Mercury is also found inside glass thermometers. Pediatricians are now urging parents to get rid of mercury thermometers in their homes. Thermometers should never be put into the trash. You can learn more about Mercury from a special kids page at the Environmental Protection Agency . Tell your parents that mercury necklaces and mercury thermometers should be taken to the Fort Worth Environmental Collection Center for proper disposal.
