Title Asbestos-like fibres of biogenic silica in sugar cane
Bibliographic information 8 Oct. 1983, Vol.2, No.8354, p.857. Illus. 7 ref.
Abstract Before sugar cane is harvested, the field may be set on fire, creating large quantities of airborne plant residue. Electron images of the residues showed structures from the mature leaf composed almost entirely of silicon, symmetrically distributed along the fibres. 5g of mature leaf digest yielded 150 hypoderm fibres, 0.85Ám in diameter and 10-300Ám long. The percentage weight of biogenic silica in mature dried leaf was 5-7%. There may be implications for carcinogenesis among sugar cane workers.
