When air or drinking water is polluted, which elements may cause people's teeth and bones to be brittle and cause pollution?

When the atmosphere or drinking water is polluted, it may cause people's teeth and bones to become brittle. The element that causes this pollution is fluorine.

Fluorine is a nonmetallic element. The main symptoms of fluorosis caused by excessive storage in human body are yellow teeth, black legs, X-shaped or O-shaped legs, hunchback or bent arms. Light poisoning leads to dental fluorosis, severe poisoning leads to skeletal fluorosis, and even completely loses the ability of self-care in work and life. Once suffering from fluorosis, it will become a disease forever, and drugs can only slow down the aggravation of the disease. Endemic fluorosis is an endemic disease that seriously endangers people's health. It belongs to the category of biogeochemical diseases, including drinking water, burning coal and drinking tea. Among them, the pollution situation of coal burning in the west is obviously heavier than that in the north and other regions, and the heaviest is Guizhou and Hubei. This is one of the main reasons for large-scale poverty in Bijie and parts of southwest Guizhou.
