Abstract
Most people administer herbal preparations of different types without
considering their side effects. Six sites were selected for the study based
on the frequency of consumption. The areas were Kofar Doka,
Danmagaji, Tudunwada, Sabongari, Kwangila and Samaru. Five
different samples were randomly collected from each area of the study.
Wet digestion method was employed to obtain clear solution of the
sample. Atomic Absorption Spectrophotometric technique was used to
quantify the levels of Lead and Cadmium in the digested samples. The
results obtained showed that the mean level of Lead in the analysed
samples ranges from 0.086 to 0.258mg/l, while that of Cadmium ranges
from 0.005 to 0.022mg/l. The levels of Lead and Cadmium were found to
exceed the WHO and USEPA permissible maximum guideline limits.
