Using two independent physical methods (Rayleigh light scattering and electron paramagnetic resonance), the effect of lead, toxic heavy metal, on proteins in aqueous solutions (including blood serum proteins) was studied. A physical mechanism of interaction between heavy metal ions and charged biopolymers which is based on formation of strong bonds of metal ions with the surface of macromolecules is discussed. Based on the results obtained, a method to monitor natural liquid media pollution with heavy metals is proposed.
