This limit is set by the World Health Organization (WHO) and is based on the latest scientific evidence. Fluoride is a naturally occurring mineral that is found in water, soil, and rocks. It is also added to some drinking water supplies to help prevent tooth decay. However, too much fluoride can cause health problems, such as dental fluorosis, which is a condition that causes white spots on the teeth. The WHO recommends that the fluoride concentration in drinking water should not exceed 1.5 mg\/liter to protect public health.<\/p>\n<p>Option A: 0.1 mg\/liter is too low.
