Fluorine, Fluoridation and Fluoride
CEU TYPE: Technical
WEBINAR TYPE: Technical
Summary: Fluorine is a naturally occurring element. It is a member of the halogen group of
elements and is very reactive. It is
never found free in nature.
The fluoride ion, F-,
is an important mineral for the human body, especially as it relates to dental
health. While a number of foods contain
fluoride, none of the foods contain sufficient fluoride for optimal health in
the amounts normally consumed. Naturally
occurring levels in water vary from 0.1 to 13 mg/l. Ocean water is typically in the range of 1.2 to
1.4 mg/l. Every natural water source on
the earth ever tested contains some natural level of fluoride. Thus it is impossible to study the nature
plant and animal life in the absence of fluoride. . A large portion of dietary
intake of fluoride (whether from water or food) passes through the digestive
system without being absorbed and is expelled in waste products from the body.
Various methods have been developed to supplement the
fluoride intake including topically application by dentists, addition of
fluoride to toothpaste, orally taken supplements for fluoride and fluoridation
of drinking water.
Fluoride has been added to drinking water on a wide scale
since mid-1940. Fluoridation of water provides an essential dietary supplement in much
the same way iodine is added to table salt. According to recent statistics from the US
Centers for Disease Control, nearly 99% of persons in Illinois on community
water systems receive fluoridated water.
This program will
explore the origin of fluoride, it’s application to water and also methods for
The presence of
fluoride can interfere with analyses of other chemicals (i.e. aluminum). This will be explored as well.
