AI Article Synopsis
- Extremely high manganese levels were found in the leaves of Pandanus tectorius in southern Guam, exceeding 10,000 microg/g dry weight in some cases.
- Historically, dried leaves of this plant were commonly used for fiber by the Chamorro people.
- There is concern about a potential connection between the high manganese content and a neurodegenerative disease similar to "manganism" that affected the island, prompting the need for further research.
Article Abstract
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.

The hala scale, Thysanococcus pandani Stickney, is an invasive insect that infests hala trees, Pandanus tectorius, and has recently arrived in the Hawaiian Islands of Maui, Oahu, and Molokai. Hala scale is native to Thailand, Indonesia, and Singapore and was accidentally introduced to Maui, with its first detection in Hana in 1995. The hala tree is a frequently planted ornamental plant throughout Hawaii's urban landscape and is also a native tree found in coastal areas of ecological suitability throughout the state.
