Young children, who often play on the floor where metallic mercury may have been spilled, are particularly at risk for effects on the central nervous system. Mercury vapors are readily absorbed into the bloodstream from the lungs, and the human central nervous system, which is still developing during the first few years of life, may become damaged. The body gets rid of mercury through the urine and feces. Removal of this substance from the body can take up to several months after exposure. Children exposed to metallic mercury for long periods may have trouble learning in school.
Prevention is the key to avoiding poisoning in homes, schools, and families.
First, avoid using metallic mercury. Appropriate substitutes are available for nearly all uses of metallic mercury. Therefore, be sure you need to use it. If not, make arrangements to safely dispose of whatever metallic mercury you might have. If you do need to use metallic mercury, make sure it is safely stored in a leakproof container.
