What may occur due to chronic exposure to low concentrations of chlorine gas? Chronic exposure may cause corrosion of the _____________.

• A. Teeth
• B. Lungs
• C. Bones
• D. Skin

Answer: (A)

Chlorine gas, when it contacts moisture, forms acids that attack hard tissues. In the mouth, saliva provides the moisture, so chronic, low-level exposure can slowly dissolve minerals from tooth enamel, leading to corrosion or erosion over time. This is a gradual chemical wear on teeth rather than an immediate injury to lungs, bones, or skin, which are less likely to show this specific chronic enamel damage at low exposure levels.
