What does the U.S. Environmental Protection Agency (EPA) say about mercury?
The following information comes from the U.S. EPA website. Italicized text has been added by the staff at BanCFLs.com for clarification purposes. Mercury exists in three forms: elemental mercury (elemental mercury is the type used in the production of compact fluorescent lights), inorganic mercury compounds (primarily mercuric chloride), and organic mercury compounds (primarily methyl mercury). All forms of mercury are quite toxic, and each form exhibits different health effects.
