Humidity percent of samples was measured and then withe ash of samples obtained by electrical furace in 550 C°. Obtained ash dissolved by 1 ml concentrated nitric acid. Flaming atomic absorption used for determination of lead and cadmium concentrations. Results: The average of lead and cadmium concentrations in samples was 0.007 ± 0.001 and 0.3± 0.08 mg/kg, respectively. The detected contents of lead and cadmium elements were lower than standard limits of WHO in hen egg.
