摘要: A total of 151 chicken eggs and 4 local feeds purchased directly from the poultry farms, at markets, along roadsides Ibadan, Nigeria, were analyzed for lead, cadmium, copper, iron, nickel, zinc, cobalt by carbon graphite atomic absorption spectrophotometry. The authors found strong, positive correlations between levels metals in corresponding eggs. overall average concentrations (mg/kg) each metal as follows: 0.59; 0.07; 0.78; 23.20; 0.03; 13.75; cobalt, 0.01. estimated daily intake iron per person was 19.5 μg, 2.4 25.6 762.3 respectively, whereas intakes 0.9 452.1 0.2 μg person. some this study did not differ appreciably determined other countries; lead cadmiu...
