In a reconnaissance soil geochemical and plant survey undertaken to study
the heavy metal uptake by major food crops in Malaysia, 241 soils were
analysed for cation exchange capacity (CEC), organic carbon (C), pH, electrical
onductivity (EC) and available phosphorus (P) using appropriate procedures.
These soils were also analysed for arsenic (As), cadmium (Cd), cobalt (Co),
chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb) and zinc (Zn)
using aqua regia digestion, together with 180 plant samples using nitric acid
digestion.
