Lead concentrations in plants and animal tissues.

The present study deals with the analysis of lead in pasture plants and tissues of goats(liver, kidney) from two areas (Arnea, Stratoni) of Central Macedonia, Greece. Analysis was carried out by Atomic Absorption Spectrometry on 42 plants and 66 specimens of goat tissues. The mean lead concentration in plants of Stratoni area was found 88 mg/kg dry weight (d/w) and of Arnea area 46 mg/kg d/w (P< 0,001). Mean lead concentration in plant specimens from both areas were higher than 20 mg/kg d/w which is the most usual concentration referred by several investigators. Mean lead concentration in tissue specimens from Stratoni area was found 0.60 mg/kg wet weight (w/w) for liver and 0.65 mg/kg w/w for kidney, while from Arnea area 0.46 mg/kg w/w and 0.27 mg/kg w/w respectively( P < 0.10 for liver, P < 0.001 for kidney). Lead levels found In tissues of goats were similar to those referred to international bibliography. [ABSTRACT FROM PUBLISHER]
