Cretan Brake (Pteris cretica L.): an Arsenic-accumulating Plant

WEI Chao-Yang, CHEN Tong-Bin *, HUANG Ze-Chun, ZHANG Xue-Qing (Department of Environmental Remediation, Institute of Geographical Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101,China).Acta Ecologica Sinica,2002,22(5  
The writers have conducted a series of field investigations in the areas with high soil arsenic background values in southern China's Hunan Province to search for arsenic accumulating-plants since 1999. It has been discovered that Cretan brake (Pteris cretica L.), from the same genus of a recently discovered As-hyperaccumulator Pteris vittata L., is also an arsenic-accumulating plant. Cretan brake thus provides us a new plant material to study the mechanism of As-accumulation. The authors suggest that further comparison studies on the two As-accumulating plants should be conducted in the future.
