CHAMPIONSGATE, Fla., Nov. 24, 2010 /PRNewswire-USNewswire/ — A new risk assessment report submitted by the International Academy of Oral Medicine and Toxicology this month to the U.S. Food and Drug Administration (FDA) warns that mercury from dental fillings is estimated to cause 67.2 million Americans to exceed the Reference Exposure Level (REL) of 0.3 ug/m3 established by the U.S. Environmental Protection Agency (U.S. EPA) in 1995. If the more protective REL of 0.03 ug/m3 established in 2008 by the California Environmental Protection Agency is used, then the current safe-dose is probably exceeded by 122.3 million Americans.
