職業ばく露
Cycasin occurs naturally, in the seeds,
roots, and leaves of cycad plants which are found in the
tropical and subtropical regions of the world. Nuts from the
cycads are used to make chips, flour, and starch. Cycasin is
not produced or used commercially. The major potential
Exposure is the ingestion of the foods containing cycasin. It is estimated that about 50 55% of the inhabitants of
Guam are potentially exposed (50,000 60,000 persons) to
cycasin. Wastewater from the preparation of the cycad nuts
contain large amounts of cycasin and represents a potential
secondary exposure source.
