Ecophysiological parameters of soil–plant system under the effect of trivalent chro­ mium and hexavalent chromium were studied using small artificial ecosystems ─ the microcosms. Emission of carbon dioxide (CO2) and nitrogen oxides (NOx) from soil and soil–plant system, morphometry and carbon concentration in shoots of Phaseolus vulgaris L. were determined. We established that effect of Cr(VI) decreased CO2 emission and increased NOx emission from soil microcosms and soil–plant microcosms. In turn, the effect of Cr(III) did not cause statistically significant changes on the emission of in­ vestigated gases in microcosms models. An inverse relationship between CO2 and NOx emissions was found by the correlation analysis. The emission intensity of investigated gases from soil without plants was higher than that from soil with plant cover. This fact stresses that the soil devoid of plant cover is an additional source of greenhouse gases emissions. Statistically significant changes effect in of Cr(VI) on morphometry and car­ bon concentration in the shoots of investigated plants was not found. In turn, Cr(III) decreased leaf growth in length and carbon concentration in shoots of P. vulgaris. Changes of investigated parameters showed that the problem of contamination of soil and groundwater with Cr(III) is important as pollution by Cr(VI).
