Levels of metals (Cd Pb Cu and Fe) in cows milk dairy products and hens eggs from the West Bank Palestine

Abdulkhaliq A., . and Swaileh K. M., . and Hussein R. M., . and Matani M., . Levels of metals (Cd Pb Cu and Fe) in cows milk dairy products and hens eggs from the West Bank Palestine. pp. 1089-1094. ISSN 2231-7546

Heavy metal contents in 160 samples of commercially available cows milk (powder and liquid) dairy products (yoghurt labaneh and white cheese) and hen eggs (conventional farms and courtyard farms) were investigated using GAAS. Mean concentrations of metals (g/g) in milk and dairy samples analyzed ranged between 0.022-0.057 for Cd ND-0.93 for Pb 0.62-0.85 for Cu and 3.2-12.91 for Fe. Results indicated high concentrations of Pb and Cd especially in powder milk samples. The lowest concentrations of metals were found in white cheese followed by liquid milk. Mean metal concentrations (g/g) in hens eggs were 0.021-0.049 for Cd 0.06-0.48 for Pb 2.29-3.26 for Cu and 15.25-33.52 for Fe. Hens eggs were found to contain significantly more Fe and Cu than milk or dairy products but generally less Pb and Cd. Finally further investigations are needed to identify the cause of elevated Pb and Cd levels especially in milk and dairy products.

Abstract

Heavy metal contents in 160 samples of commercially available cows milk (powder and liquid) dairy products (yoghurt labaneh and white cheese) and hen eggs (conventional farms and courtyard farms) were investigated using GAAS. Mean concentrations of metals (g/g) in milk and dairy samples analyzed ranged between 0.022-0.057 for Cd ND-0.93 for Pb 0.62-0.85 for Cu and 3.2-12.91 for Fe. Results indicated high concentrations of Pb and Cd especially in powder milk samples. The lowest concentrations of metals were found in white cheese followed by liquid milk. Mean metal concentrations (g/g) in hens eggs were 0.021-0.049 for Cd 0.06-0.48 for Pb 2.29-3.26 for Cu and 15.25-33.52 for Fe. Hens eggs were found to contain significantly more Fe and Cu than milk or dairy products but generally less Pb and Cd. Finally further investigations are needed to identify the cause of elevated Pb and Cd levels especially in milk and dairy products.
