Abstract:
A
sensitive and efficient method was optimized for determination
of lead in saliva and blood by Graphite Furnace Atomic
Absorption Spectroscopy (GFAAS). Calibration curves were linear
over the concentration range 10-200 ng mL-1. Intra-
and inter-day precision (relative standard deviation) values for
lead were less than 6.8%. The limits of quantification (LOQ) and
detection (LOD) of method were 7 ng mL-1 and 5 ng mL-1,
respectively. Also the optimized and validated GFAAS method was
successfully applied to 282 healthy adults saliva and blood from
three areas of Turkey. The mean levels of lead in saliva and
blood were found as 39.7 ± 17.74 ng mL-1 (equivalent
to 3.9 ± 1.77 μg dL-1) and 49.4 ± 23.14 ng mL-1
(equivalent to 4.9 ± 2.31 μg dL-1), respectively.
