What happens when water contains 8-20 ppm of fluoride concentration?a)...
Effects of 8-20 ppm Fluoride Concentration in Water:

Crippling Fluorosis:
- When water contains 8-20 ppm of fluoride concentration, it can lead to crippling fluorosis.
- Crippling fluorosis is a severe skeletal disorder caused by excessive fluoride intake over a long period.
- It results in joint stiffness, severe pain, and skeletal deformities, ultimately leading to disability and reduced quality of life.
- This condition is irreversible and can have a significant impact on an individual's overall health and well-being.
In comparison to the other options provided:
- Blue baby disease is caused by high nitrate levels in water, not fluoride.
- Dental fluorosis occurs at lower fluoride concentrations and results in the discoloration and weakening of tooth enamel.
- Mottling of teeth is a cosmetic issue caused by excessive fluoride intake during tooth development.
Therefore, the correct answer in this case is crippling fluorosis.
