摘要

Concentration of 7 heavy metals, Zn, Fe, Cu, Cr, Cd, Pb and Ni in mudflat sedimens, mangrove root sediments and root tissues of Acanthus ilicifolius, Aegicerus corn- iculatum and Kandelia cande form the Mai Po Nature Reserve, Northewst Hong Kong, were measured. Metal Concentrations in the upper 0-10 cm of the sediment cores From the mudflat were 4-25/100 higher than those found in The bottom 21-30 cm.
