Fluoride pollution mainly affects the:

Explanation

Fluorides are given out during the refining of materials. Fluorides cause fluorosis. It is a disease that is defined by mottling of teeth, abnormal bones that are liable to fracture because fluorine replaces Ca2+ and makes the bones brittle. High levels of fluoride in drinking water can have adverse effects on dental and skeletal health. In areas with excessive fluoride in water, it can lead to dental fluorosis, a condition characterized by discolored, pitted, or mottled tooth enamel. In severe cases, excessive fluoride intake can result in skeletal fluorosis, which can cause joint pain, bone deformities, and reduced mobility.
