Abstract
Abstract Genotoxicity of Cu and Zn was assessed by use of the micronucleus (MN) test on Vicia faba roots. Plants were exposed to various leachates of raw and anaerobically digested pig slurry, with maximum total concentrations of 200 μM Cu and 600 μM Zn. The results indicated stabilisation of the organic matter during anaerobic digestion of the slurry and bioconversion of some phytotoxic organic compounds (e.g. phenols or p -cresol), but did not show a relationship between Cu and Zn concentrations and MN frequency. Exposure of Vicia plants to binary inorganic solutions of Cu and Zn (CuSO 4 /ZnSO 4 , 1:3) showed a significant micronucleus induction at concentrati...
