title: Lead and cadmium concentrations in goat, cow, sheep, and buffalo milks from different regions of Iran.
abstract: In total, 137 goat, cow, sheep, and buffalo milk samples were collected in different regions of Iran and analysed to determine concentrations of lead and cadmium by a graphite furnace atomic absorption spectrometric method. The mean recovery of the analytical method was 96.3% and 104% for cadmium and lead, respectively. The mean lead and cadmium contents obtained from 137 samples were 1.93 ± 1.48 (range: 0.18-6.11 ng/ml) and 9.51 ± 4.93 ng/ml (range: 1.84 ng/ml-30.50 ng/ml), respectively. Lead concentration in 8.1% of sheep and 1.9% of cow milk samples was higher than the newly established Codex standard. The mean concentrations of cadmium and lead in animals aged ≤ 3 years (n=80; 1.40 ± 1.05 ng/ml and 7.91 ± 3.60 ng/ml, respectively) were lower than in animals aged >3 years (n=58; 2.69 ± 1.67 ng/ml and 11.8 ± 5.71 ng/ml, respectively).
