Changes of bound amino acids content of water-soluble proteins in meristematic cells of maize seedlings roots under the action of lead ions was investigated. Level of amino acid accumulation was dependent on xenobiotic concentration and time of germination. General tendency of nickel ions action was decrease of arginine, leucine, alanine content and increase of histidine, cysteine, serine, praline and valine amount.
