Özet:

 

In this study, we aimed to determine the levels of lead (Pb), cadmium  (Cd), arsenic (As) and mercury (Hg) in pasta samples.  These metals  were determined from samples of wheat, semolina and pasta taken during  their processing stages after taking into account the critical  production steps that may affect metallic contamination.   Determination of heavy metal contents was realized by an atomic  absorption spectrophotometer and the stage of sample preparation prior  to measurement by using a microwave digestion system in a closed  vessel.  Variations in the heavy metal content of the samples taken during the  production of pasta were found to be significant from the statistical  viewpoint (p < 0.05).  In general, a decrease was observed in  metallic content during semolina production and an increase was  observed during the transition from semolina to pasta.  The heavy  metal contents of samples studied were compared with those reported by  other researchers in different countries and similar values were  indicated.
