Abstract Raman and infrared spectra were made of mercuryII, cadmium and aluminum benzoates To better understand the mechanism of toxic action of heavy metals, comparisons were made of the effects of mercuryI, mercuryII, leadII, cadmium barium, strontium, copperII, aluminum, ironIII zinc, magnesium, calcium, yttrium, lanthanumIII neodymiumIII, dysprosiumIII, luthetiumIII, lithium sodium, and potassium on the aromatic system of benzoic acid. Benzoic acid was considered to be model compound, representing a wide group of aromatic ligands present in enzymes. Oscillation (Raman, IR) and electronic (UV) spectroscopy methods were applied. Heavy toxic metals, particularly HgI, HgII, and PbII in contrast to Ca, Mg, Al, FeIII, Zn, Y, and LnIII perturb the aromatic system of benzoic acid by deforming the uniforming distribution of π electron charges in the ring.
