The main part of this contribution deals with polluting matter which are generated by burning of unprocessed amaranth-phytomass. Ash analysis showed that the residue ash contains: 1 mg/kg of cadmium; 5.05 mg/kg of cobalt; 11.28 mg/kg of copper; 4.9 mg/kg of nickel; 34.3 mg/kg of zinc. There are also mentioned further analyses besides the above mentioned elements in the contribution, but these did not overstep the SR limit of concentrations (the Slovak Republic limit of element concentrations) of topical elements. Results of the analyses, which were aimed at determination of concentration of chosen heavy metals in solid residue after thermal oxidation of amaranth biomass-phytomass, have proved that this plant has a tendency to absorb some heavy metals from the surroundings - the soil in which it was growing and without doubt they are dangerous by their physiological activity for living organisms.
