Question

Even small exposure to ${\mathrm{H}}_2\mathrm{S}$ causes giddiness.

• A. True
• B. False

Answer 1

The correct option is A True

• Inhalation of high concentrations of hydrogen sulfide (${\mathrm{H}}_2\mathrm{S}$) can produce extremely rapid unconsciousness and death.
• Hydrogen sulfide is both an irritant and a chemical asphyxiant that affects both oxygen utilization and the central nervous
  system.
• An asphyxiant is a substance that can cause unconsciousness or death by suffocation.
• Low concentrations irritate the eyes, nose, throat, and respiratory system.

Therefore, the statement even small exposure to ${\mathrm{H}}_2\mathrm{S}$ causes giddiness is true.
