Abstract: The
analysis of heavy metals Pb and Cd concentrations in fish and oyster have been
carried out by atomic
absorption spectrophotometer (AAS)
method. The wet
digestion method was used for preparation sample prior to AAS
detection. Sample was collected from three different location rivers at
Lamnyong, Pantee Pirak and Lumbago. The result showed that the Pb and Cd concentration
in fish and
oyster at difference
location were obtained
not difference significantly. Pb
and Cd contents in fish and oyster were found below lethal concentration. The AAS instrument
was still valid
to use as
the instrument which
is obtained of
accuration of 0.65% and precise
of 0,019 ppm still lower than threshold value of 1% and 0.04 ppm.
