[Content of cadmium and lead in berries and seed fruits].
By the method of atomic absorption spectrometry (AAS) the content of cadmium and lead was determined in 217 samples of various fruits from an agricultural region. The purpose of the work was a preliminary trial for establishing whether under similar conditions of cultivation environment it would be possible to demonstrate differences in the ability of accumulating cadmium and lead in relation to the type and species of fruit-bearing plants. Berries were found to contain higher amounts of both elements than grain fruits. The mean values of these elements were for berries from 0.012 to 0.077 mg Cd/kg and from 0.04 to 0.15 mg Pb/kg, and in grain fruits these values were from 0.007 to 0.008 mg Cd/kg and from below 0.02 to 0.02 mg Pb/kg. The greater ability of Cd and Pb cumulation by berries may be due to the well known ability of this type of fruit to accumulate also other mineral components, such as Ca, Fe, P, Mg, K, and among these Ca and Fe are known to reduce the toxicity of Cd and Pb.
