The Heavy Metal Content in Chicken Eggs Consumed in Van Lake Territory

Dietary Intake of Metals from Fresh Cage-Reared Hens’ Eggs in Tenerife, Canary Islands

“…The concentrations of Cu and V obtained by Demirulus [43] are higher than those obtained in the present study. The concentration of Mg obtained by Alam Chowdhury et al [48] is lower (43.26 mg/kg) than that obtained here (81.2 mg/kg), and the level of nickel is higher (12.81 mg/kg) than that obtained at the present study.…”

“…As regards the metal content obtained in the yolk samples in the present research, the levels of Cu, Mn, Ni, and Zn obtained by Demirulus [43] are higher than those obtained here. The concentrations of Cu, Zn, Mn, and Mo reported by Giannenas et al [42] are higher than those obtained in the present study.…”

Essential elements content of hen egg-white in Markazi province (Iran)

“…Zinc content in egg yolk according to Mabe et al (2003) was 37.08 mg/kg and 30.35 ± 2.73 mg/kg according to Kaya et al (2009). Zinc level in albumen and yolk egg samples from Turkish villages and counties was 7.4 mg/kg, 4.3 mg/kg, 35.6 mg/kg, and 43.2 mg/kg, respectively (Demirulus, 2013). Demirulus argued that variation of Zn contents in yolk and albumen of eggs from villages and counties can be because of geographical and dietary differences and environmental pollution.…”

A Study on the Levels of Heavy Metals in Poultry Eggs in Chittoor District of Andhra Pradesh

“…Another study by Demirulus (2013) revealed the average concentrations of heavy metals were found as follows: Zn: 35.6 ppm and 42.2 ppm in yolk, 4.3 ppm and 7.4 ppm in albumen; Cu: 2.7 ppm and 10.5 ppm in yolk, 7.0 ppm and 1.5 ppm in albumen; Cd: 0.34 ppm and 1.24 ppm in yolk, 0.31 ppm and 1.25 ppm in albumen; Mn: 1.9 ppm and 6.8 ppm in yolk, 2.0 ppm and 4.5 ppm in albumen; Ni: 1.7 ppm and 3.1 ppm in yolk, 2.8 ppm and 3.7 ppm in albumen respectively and several studies conducted by different authors like Farhani et al, (2015) found the mean concentrations of heavy metals in egg-white as follows: 0.119 for Al, 0.785 for As, 0.750 for Pb, 0.249 for Cd, 0.270 for Hg and 0.186mg/kg for Sb and similarly Abbasi et al, (2015)showed the mean concentrations of cadmium, lead, arsenic, nickel, copper, iron and zinc in collected chicken eggs were 0.01, 0.074, 0.03, 0.014, 1.46, 34.37 and 12.55 mg/kg, respectively. The Study conducted on the important heavy metal (i.e.)…”
