Abstract
The quality of marketed vegetables cannot be guaranteed as many of them has been contaminated with heavy
metals such as lead, cadmium and arsenic. These heavy metals can act as either growth supporter or threat
depending on their types and amount absorbed by the plants. The consumption of an excessive amount of
heavy metals in vegetable may cause several diseases such as renal dysfunction and bone depletion. There
are few methods used to detect heavy metal contamination such as Atomic Absorption Analysis (AAS),
Neutron Activation Analysis (NAA), X-ray Fluorescence Spectroscopy (XRF) and Inductively Coupled Plasma
Spectrometry (ICPMS). This paper discusses all these methods to compare their efficiency, advantages and
disadvantages to select the best method for heavy metal detection in vegetables.
