Determination of Lead in Human Nail for Ten Years by Graphite Furnace Atomic Absorption Spectrometry

Zhang Tai

Abstract

There are 36 portions of nail's sample collected from same person quarterly in 10 years,and the content of lead in the samples was determined by graphite furnace atomic absorption spectrometry.This method has good precision and accuracy,the recovery rate is 91.3%—107% with relative standard deviation of 4.1%.
