Heavy metals determination in brinjals and tomatoes / Normaliza Ismail

Ismail, Normaliza (2009) Heavy metals determination in brinjals and tomatoes / Normaliza Ismail. [Student Project] (Unpublished)


In this study, 2 types of tomatoes and brinjals that were cherry tomato,
beefsteak tomato, long brinjal and oval brinjal were chosen as samples.
This study was carried out with the aim to assess the levels of arsenic
(As), cadmium (Cd), copper (Cu), manganese (Mn), lead (Pb) and zinc
(Zn) concentration in brinjals and tomatoes sold in supermarket.
Inductively Coupled Plasma (ICP) was used to determine the levels of
these metals. Samples were prepared by using dry ashing method. In this
study, only heavy metals of Cu, Mn, and Zn were found in tomatoes and
brinjals. Zn had the highest while Cu was the lowest mean concentration
for both types of brinjals and tomatoes. The concentration of copper is
higher in oval brinjal than in long brinjal. The concentration of
manganese and zinc were higher in long brinjal compared to oval
brinjal. The concentration of copper, manganese and zinc were higher in
cherry tomato than in beefsteak tomato. The concentrations of Cd, Cu
and Pb in both types of tomatoes and brinjals were lower than those
detected in Pakistan. The Zn level was higher than that found in
Pakistan tomatoes and brinjals. Although, the concentration of Zn was
higher than that reported studies in Pakistan for both tomatoes and
brinjals, it was below than Provisional Tolerable Daily Intakes (PTDI)
value. So, the, consumption of these vegetables does not pose a health
risk to human.
