Determination of Some Heavy Metals Level in Kashar Cheese Produced in Thrace Region

Abstract

In this research, 50 samples of kashar che ese produced and sold in Trakya (Thrace) region, we re studied for analysis of heavymetalsasLead (Pb), tin(Sn), copper (Cu) and mercury (Hg). Heavy metal contents of samples vi/ere determined by AtomicAbsorptionSpectrophotometerlAAS) afterhavingbeenburned in a microwave oven.As a resultofthisstudy, average heavy me tal contents of 50 s amples found as; lead (Pb):0.0600 ppm, tin (Sn): 0.0366 ppm, copper (Cu): 0.5036 ppm, mercury(Hg): 0.0214 ppm. The obtained re suits show that mean concentrarions of copperandtininsamplesare below average levels whereas some results in lead and mercuryare above the average levels.

Bu çahjmada Trakya Bölgesinde üretilen kajar peynirlerinin kurjun (Pb), kalay (Sn), bakir (Cu) ve civa (Hg) i ce riklerinin belirlenmesi amaçlanmijtir. Bu a macla bölgedenSOadetkajar peyniri örnegi topi an mijtir.
