title: Cadmium and lead in animal tissue (muscle, liver and kidney), cow milk and dairy products in Korea.
abstract: A survey of Cd and Pb in animal tissue, milk and dairy products was conducted. Muscle, liver and kidney of domestically produced cows, pigs, chickens and ducks were collected from eight regions in Korea. Raw cow milk was collected from 9 regions, and imported dairy products (butter, cheese, cream and powdered milk) were collected from 15 countries. Cd and Pb were analysed by inductively coupled plasma mass spectrometry (ICP-MS) after microwave digestion. Concentrations of Cd and Pb did not exceed the Korean legal maximum levels in any of the samples. Correlation coefficients were estimated between concentration of Cd or Pb and animal age and between muscle, liver and kidney. In cows, there were good correlations between age and Cd in kidney (r = 0.748) and between Cd in liver and in kidney (r = 0.878). Continuous monitoring will be an important role to safeguard consumers in the event of a food contamination incident.
