Mercury
Mercury is an element that naturally occurs in rocks, soil, water, and air. In its pure form, mercury is a shiny, silver-white, odorless liquid. Mercury is the only metal that is liquid at room temperature. While mercury can come in many chemical forms, it cannot be created or destroyed because it is an element.
The health effects of mercury can range from none -- to subtle -- to severe -- and even death, depending on the specific form of mercury a person is exposed to, the route of the exposure (for example, inhalation or ingestion), the amount of mercury, and the duration of the exposure to mercury. Mercury primarily affects the nervous system (brain and nerves) and the kidney.
Mercury exposure is a serious concern for fetuses, infants and children because their rapidly developing nervous system is especially vulnerable. Our advice about mercury is designed to protect fetuses, infants and children, as well as adults.
