True or False: Exposure of aircrew to airborne toxins can lead to acute or chronic health effects?

• A. True
• B. False
• C. Sometimes
• D. Not sure

Answer: (A)

Airborne toxins can cause health effects in aircrew. Inhaled irritants or toxicants can trigger immediate, acute symptoms such as eye, nose, and throat irritation; coughing or chest tightness; headaches or dizziness; and nausea. With repeated or longer exposures, or higher doses, there can be longer-term, chronic effects like persistent cough, bronchitis or asthma-like symptoms, decreased lung function, and potential systemic or neurocognitive impacts depending on the substance involved. The aviation environment includes various toxin sources—cabin air contaminants, engine or oil fumes, ozone from electrical components, and smoke—in which both short-term and long-term health risks are plausible. Because these risks exist and depend on dose and duration, the statement is true.
