This study was carried out to estimate the heavy metal contents (Pb, Cd, Cr, Cu, Mn) in avian eggs sold in Seoul area, Korea from August to December, 2010. The contents of lead, cadmium, chrome, copper, manganese were estimated by inductively coupled plasma mass spectrometry. The concentrations of heavy metals (mean±standard deviation, mg/kg) in the avian eggs were as follows: Pb 0.010±0.018, Cd 0.000±0.001, Cr 0.018±0.022, Cu 0.637±0.163, Mn 0.397±0.132. The contents of lead and cadmium in the eggs were lower than that in meat and other foods of previously reported results. Whereas the contents of copper, manganese were similar to the previously previous results. The average daily intakes of lead and cadmium in the avian eggs were 0.1 and 0.8% respectively, as compared with PTWI (Provisional Tolerable Weekly Intakes) established by FAO/WHO Expert Committee for Food Safety Evaluation.
