Fluorine: Key health benefits and risks Q & A

Fluorine is a non-metallic element which is toxic in its gaseous form. Fluorine is known to be beneficial to humans, specifically for its role in maintaining bones and tooth enamel, but it has not yet been proven to be essential for human health.

Q. I know that a compound of fluorine, called a fluoride, is often added to some brands of toothpaste, and even to some water supplies to help reduce cavities. Does it really work for that?
A. Yes. Tooth decay rates are much higher than average in areas in which the drinking water is naturally low in fluorine. When adequate amounts of fluoride are incorporated into tooth enamel, the rate of tooth decay is substantially reduced. Studies show that it works not only for children's teeth, but for adults, too.

Effect of climate change on health

As our climate changes, the risk of injury, illness, and death from the resulting heat waves, wildfires, intense storms, and floods rises.

Climate change poses a wide range of risks to population health - risks that will increase in future decades, often to critical levels, if global climate change continues on its current trajectory.

The majority of the adverse effects of climate change are experienced by poor and low-income communities around the world, who have much higher levels of vulnerability to environmental determinants of health, wealth and other factors, and much lower levels of capacity available for coping with environmental change.
