## Abstract The metal content (Cu, Fe, Ni, Pb) of Finnish margarines manufactured in 1978โ80 were investigated by the flameless atomic absorption spectrophotometry method. Copper, iron and nickel were digested by the dry ashing method whereas for lead both dry ashing and wet ashing were employed. T
Feedstuffs can be effectively dissolved by treatment with concentrated sulfuric acid and \(30 \%\) hydrogen peroxide in approximately \(30 \mathrm{~min}\) for the rapid determination of elements at both the \(1 \%\) level and the trace level by flame and electrothermal atomic absorption spectrometry
