fluoriidides
Fluorides are chemical compounds containing fluorine with a negative charge or in a lower oxidation state. They are commonly found in nature, particularly in minerals like fluorite, cryolite, and apatite. In water, fluorides exist as dissolved ions. The concentration of fluoride in natural water sources can vary significantly depending on geological factors. Human activities can also introduce fluorides into the environment, although natural sources are generally more prevalent.
Fluoride plays a significant role in human health, primarily through its beneficial effects on dental enamel.
