Extremely high levels of manganese (Mn) were encountered in foliar tissue of the monocot tree Pandanus tectorius from southern Guam with values exceeding 10,000 microg/g dry weight in some wetland representatives. Historically, dried Pandanus leaves were used extensively as a source of domestic fiber in the local Chamorro culture. A possible link between the use of this plant and a neurodegenerative disease complex that once plagued the island and is symptomatically similar to the occupational disease "manganism" poses an intriguing question that merits further investigation.
