## Discrepancy

AFTER STARTING THE ENG FOR A SCENE FLIGHT, THE NURSE & MEDIC DETECTED AN UNIDENTIFIED ODOR.  ATTEMPTS TO LOCALIZE & IDENTIFY THE ODOR WERE UNSUCCESSFUL & WE ELECTED TO SHUT DOWN WITH NO FURTHER INCIDENT.  AFTER ADDITIONAL GND RUN, THE ODOR WAS DETERMINED TO BE DUST & POLLEN IN THE HEATER DUCT.  THE ACFT WAS RETURNED TO SERVICE.
