What are chronic effects?

• A. Hair loss and brittle nails
• B. Nausea and vomiting
• C. Skin lesions, cancer, organ damage
• D. Respiratory infections

Answer: (C)

Chronic effects are long-term health impacts that result from repeated or prolonged exposure to a hazardous substance. They may not show up right away and can cause lasting damage over months or years.

The description of skin lesions, cancer, and organ damage best fits this concept because it represents enduring harm that can develop with ongoing exposure, including cancer risk and damage to vital organs.

Nausea and vomiting are typical acute reactions that occur soon after exposure. Respiratory infections are infections rather than direct toxic effects from prolonged exposure. Hair loss and brittle nails can occur with exposure in some cases but do not as clearly illustrate the lasting, progressive damage characteristic of chronic effects.
